LevelPlay Unity package/SDK Integration

Treat this as an interactive workflow to run with the developer, not as background reference. Work through the steps below and the linked reference files rather than answering ad-integration questions from general knowledge.

The C# scripts generated in this skill are MonoBehaviour files for the user to save to their project, not for inline execution.

Follow the integration workflow sequentially, one step at a time. Ask only the questions for the current step — do not gather information for future steps in advance. Wait for the user's response at each checkpoint before proceeding.

LevelPlay is Unity's ad mediation platform: it connects your game to multiple ad networks simultaneously and runs a unified auction across multiple ad networks and bidders to maximize competition for each impression. This guide walks you through the full integration: installing the SDK, configuring dependencies for Android and iOS, initializing LevelPlay in your project, and implementing rewarded, interstitial, and banner ads. If you already have part of this set up, you can skip ahead to the relevant step.

Integration Workflow

0. New Integration or Migration?

Ask: "Are you starting a new LevelPlay integration, migrating an existing one (from an older SDK version or from Unity Ads), or troubleshooting an existing setup?"

New integration: proceed to Step 1.
Migration (SDK upgrade, replacing IronSource.Agent APIs, migrating from Unity Ads, or fixing a Maven Central Android build failure): Read references/migration-sdk-9.md. Ask which of the five scenarios applies — A = SDK upgrade, B = init API migration, C = ad unit API migration, D = Maven Central build failure, E = Unity Ads migration — then follow the matching scenario. After applying all code changes, work through the Migration Completeness Checklist (section C5 of the reference) — it catches requirements that a line-by-line translation misses because the legacy code had no equivalent line. Then run a compilation check if the environment allows (dotnet build, or ask the user to check the Unity console). If compilation errors appear, diagnose and fix them before presenting results. If no compilation check is possible, do not block or keep retrying — list the files you changed, ask the user to check the Unity console, and continue.
Troubleshooting or adding to an existing setup (ATT, GDPR, ILRD, Test Suite, build errors on a fresh integration, or adding a feature to an already-working integration): Identify what the user needs and go directly to the relevant step or reference from "When to Read Detailed References."

1. Verify Unity Environment

Check that the user is working in a Unity project by verifying Assets/ and ProjectSettings/ directories exist. If not in a Unity project, instruct the user to navigate to their Unity project directory. If those directories are not found but the user believes they are in the right place, ask: "It looks like you may not be at your project root — can you navigate to the top-level folder of your Unity project and confirm you can see Assets/ and ProjectSettings/ there?"

2. Understand Business Goals

Before implementing ad units, determine the user's optimization priorities to recommend the appropriate ad unit strategy. Ask:

"What's your primary optimization goal?"

Revenue-focused: Maximize ad revenue and impression opportunities
UX-focused: Prioritize gameplay flow and user satisfaction
Balanced: Optimize for both revenue and UX
Not sure yet: Default to Balanced and proceed. At Step 8, briefly note you're using Balanced since they were unsure, and invite them to indicate a different preference now that they've seen the format options.

Record this answer for later strategy recommendation in Step 8.

3. Install LevelPlay SDK via UPM

If the SDK is already installed: Ask the user to verify 'Ads Mediation' appears under 'Packages: In Project' in the Package Manager. If it does, proceed directly to Step 4.

Guide through installing the LevelPlay Unity package using Unity Package Manager:

Open Unity → Window > Package Manager
Select Unity Registry dropdown or Services tab
Search for "Ads Mediation" package
Review package description to confirm it's the LevelPlay SDK
Click Install button
Wait for package to download and import

When you install the package, you may see a prompt to install Mobile Dependency Resolver — click Import if it appears. This is covered in more detail in the next step.

Verify the package appears under "Packages: In Project" in Package Manager after installation.

Network Manager: Access Ads Mediation > Network Manager at any time to install additional ad network adapters and check for SDK and adapter updates.

For iOS builds, note that SKAdNetwork configuration will be needed later (reference references/ios-setup.md when ready for iOS builds).

4. Resolve Native Dependencies (Critical)

Critical for Android/iOS builds: LevelPlay requires native dependency resolution. Without this, code compiles in Unity Editor but fails during platform builds with gradle (Android) or CocoaPods (iOS) errors.

Platform checkpoint — ask before proceeding: "Which platform(s) are you targeting — iOS, Android, or both?" Record this. It determines which dependency resolution steps apply here, whether ATT is required (Step 6.5), and which testing steps are relevant (Step 10).

LevelPlay requires native Android/iOS libraries that Unity's package manager alone doesn't handle. A dependency manager bridges this gap. If you've never added one to your project, don't worry; we'll walk you through it.

Check for existing dependency manager:

Ask: "Do you have a dependency manager like Mobile Dependency Resolver (MDR), Unity External Dependency Manager (UEDM), or External Dependency Manager for Unity (EDM4U) installed? Check your Assets folder for these tools."

If unsure: Check Assets folder in Unity for folders named 'Mobile Dependency Resolver', 'External Dependency Manager', or 'EDM4U'. If you see any folder with these names, answer 'Yes'. If not, answer 'No'.

If they HAVE a dependency manager:

For Android:

With newer versions of Mobile Dependency Resolver (shipped with the Ads Mediation package): Dependencies auto-resolve on build (no manual action needed). If unsure, try building first — if it fails, manually resolve via the Android Resolver menu.
With older MDR or other managers: Go to Assets > [Your Dependency Manager] > Android Resolver > Resolve
Example paths:
- MDR: Assets > Mobile Dependency Resolver > Android Resolver > Resolve
- EDM4U: Assets > External Dependency Manager > Android Resolver > Resolve
Menu paths may vary depending on dependency manager version. Look for 'Android Resolver' under your dependency manager's menu.

For iOS:

All dependency managers require manual CocoaPods installation:
- MDR: Assets > Mobile Dependency Resolver > iOS Resolver > Install Cocoapods
- EDM4U: Assets > External Dependency Manager > iOS Resolver > Install Cocoapods
- UEDM: Similar path under Unity External Dependency Manager

Ask: "Have you run the dependency resolution for your target platform(s)?"

If targeting both Android and iOS, complete dependency resolution for both platforms before proceeding.

If they DON'T have a dependency manager:

If the user didn't see the Mobile Dependency Resolver prompt during installation (see Step 3), restart Unity Editor — the prompt may appear after restart. If it still doesn't appear, they may already have a dependency manager installed.

When prompted:

Click Import on the prompt to install Mobile Dependency Resolver
After installation:
- Android: Dependencies will auto-resolve on build (newer MDR versions)
- iOS: Go to Assets > Mobile Dependency Resolver > iOS Resolver > Install Cocoapods

Alternative: Install another dependency manager like EDM4U if preferred (search for installation instructions in their documentation).

Note: Unity is transitioning to Unity External Dependency Manager (UEDM). If available in your Unity version, prefer UEDM over MDR.

Verification:

After resolution, verify:

Android: Gradle dependencies in Assets/Plugins/Android/
iOS: Podfile references or CocoaPods installation confirmation in console

If dependency resolution fails: Check the Unity console for specific error messages and share them for troubleshooting — or see the Common Issues and Solutions section below for gradle and CocoaPods error guidance.

Android Custom Main Gradle Template (Older LevelPlay Versions):

For older LevelPlay Unity package versions, manually enable the Custom Main Gradle Template:

Go to Edit > Project Settings > Player
Select Android tab
Expand Publishing Settings
Under Build, check Custom Main Gradle Template

In newer LevelPlay Unity package versions (with newer Mobile Dependency Resolver), this is enabled automatically by default.

Android API 33+ Requirement:

If targeting Android API level 33 or higher, declare the AD_ID permission in AndroidManifest.xml:

<uses-permission android:name="com.google.android.gms.permission.AD_ID"/>

This permission is required for advertising ID access on Android 13+.

If you skip this step and target Android API 33+: advertising ID access will fail on Android 13+ devices.

5. Get App Key and Ad Unit IDs

Before initializing LevelPlay, collect credentials from the LevelPlay dashboard.

Dashboard: https://platform.ironsrc.com/

New to LevelPlay? Set up your app and ad units first:

App Key: In the dashboard, go to Apps in the left sidenav → find your app → copy the alphanumeric string displayed under the app title.

Ad Unit IDs: Go to Ad units in the left sidenav → select your app → copy the ID for each format you plan to implement (Rewarded, Interstitial, Banner).

Note: You need your App Key now for initialization (Step 7). Ad Unit IDs are only needed at Step 9 — if you haven't decided which ad formats to implement yet, just copy your App Key for now and return here after Step 8.

Keep both accessible — you'll need them in the next steps.

6. Configure AdMob Keys (If Using AdMob Network)

When to use: Only if using AdMob as a mediation network adapter in LevelPlay.

If using AdMob, configure platform-specific app keys in Unity Editor:

Access: Ads Mediation > Developer Settings > LevelPlay Mediation Settings

Configuration:

Android App Key: AdMob Android app key
iOS App Key: AdMob iOS app key

This configuration is required for AdMob to work as a mediation network in LevelPlay.

Troubleshooting: If you don't see the 'Ads Mediation' menu in Unity Editor, verify the Ads Mediation package is installed (Step 3) and restart Unity Editor.

6.5. Privacy & Regulation Settings (If Required)

Note: This skill provides technical integration guidance, including for LevelPlay's privacy APIs. It is not legal advice, and it does not determine which laws apply to your app — that depends on your users, your data practices, and your distribution. Consult your own legal counsel, and refer to Regulation Advanced Settings for Unity for the authoritative LevelPlay documentation.

Ask the user: "Do you need to configure privacy settings for GDPR, CCPA/CPRA (or certain state privacy consumer acts), or for child-directed apps?"

If YES to any:

Privacy settings must be configured BEFORE SDK initialization. See references/privacy-settings.md for complete implementation guide.

Quick examples:

GDPR:

SDK 9.5.0+ — global consent boolean:

using Unity.Services.LevelPlay;

// true = user has granted consent, false = user has not consented
LevelPlayPrivacySettings.SetGDPRConsent(true);

SDK 9.4.x — per-network consent dictionary (check your SDK version in Network Manager):

using Unity.Services.LevelPlay;
using System.Collections.Generic;

// Add an entry for each ad network you have installed
LevelPlayPrivacySettings.SetGDPRConsents(new Dictionary<string, bool> {
    { "UnityAds", true },
    { "IronSource", true }
    // See references/privacy-settings.md for the full network key list
});

If neither API compiles, your Unity package/SDK may be below 9.4.0 — upgrade via Ads Mediation > Network Manager.

CCPA (SDK 9.4.0+):

using Unity.Services.LevelPlay;

LevelPlayPrivacySettings.SetCCPA(true); // User opted out of data sale

COPPA (SDK 9.4.0+):

using Unity.Services.LevelPlay;

LevelPlayPrivacySettings.SetCOPPA(true); // Child-directed app

The CCPA and COPPA APIs above also require SDK 9.4.0+. If either fails to compile, upgrade your Unity package/SDK via Ads Mediation > Network Manager.

Call these BEFORE LevelPlay.Init() in Step 7.

For complete implementation with UI, consent management, and combined regulations, see references/privacy-settings.md.

For iOS builds — required regardless of privacy regulations above: Also implement App Tracking Transparency (ATT) before proceeding to Step 7. Apple requires ATT authorization before your app tracks users or accesses the device's advertising identifier on iOS 14.5+. Request ATT authorization before calling LevelPlay.Init() — this is both an Apple platform requirement and necessary for personalized ads (which also affects fill rate). See references/ios-setup.md for the ATT implementation code.

If NO privacy regulations and not targeting iOS: Skip this step and proceed to Step 7.

7. Initialize LevelPlay SDK

Installation checkpoint:

Before providing initialization code, confirm:

If the user confirmed they are not using AdMob, omit the Step 6 item from the confirmation below.

If following the sequential workflow and Steps 3 and 4 have already been confirmed in this conversation, skip those items — only ask about Step 5 and Step 6 (if AdMob).

"Please confirm these are working correctly:

Step 3: Do you see the 'Ads Mediation' package in Unity Package Manager under 'Packages: In Project'?
Step 4: Have you run dependency resolution for your target platform(s) without errors?
Step 5: Do you have your App Key copied from the LevelPlay dashboard?
Step 6 (only if using AdMob): Have you configured AdMob keys in Unity Editor settings?

Verify these are working before proceeding."

If they answer NO or are unsure:

Missing Step 3: Code will show CS0246 namespace errors → Direct to Step 3
Missing Step 4: Code compiles but Android/iOS builds will fail → Direct to Step 4
Missing Step 5: They won't have credentials to initialize → Direct to Step 5
Do not provide C# code until they confirm all steps are complete

If they answer YES:

Optional — Analytics: ILRD Wiring. Ask this question verbatim — do not summarize or rephrase it: "Do you use an analytics or attribution platform (Firebase, AppsFlyer, Adjust, Singular, or custom backend) that needs ad revenue data? If yes, the integration will include a logging stub for Impression Level Revenue (ILRD) — a few lines of code, no analytics platform setup required yet. (Yes / No / Not sure — defaults to yes)" Record the answer.
Proceed with initialization code.

LevelPlay SDK must be initialized before loading or showing any ads. Initialization should happen early in the application lifecycle.

Ask how they want to handle initialization. Present all four options exactly as listed — do not condense or omit any:

Create a new dedicated script for LevelPlay initialization
Add to an existing initialization/manager script they already have
Create a new LevelPlay script that your existing manager calls
Just show me the initialization code — I'll decide how to integrate it

Option 1: Creating a New Script

If creating a new script (e.g., LevelPlayInitializer.cs), use this complete class:

using UnityEngine;
using Unity.Services.LevelPlay;

public class LevelPlayInitializer : MonoBehaviour
{
    [SerializeField] private string appKey;

    void Awake()
    {
        // Persist across scene loads so ads stay initialized
        DontDestroyOnLoad(gameObject);
    }

    void Start()
    {
        // Register initialization callbacks
        LevelPlay.OnInitSuccess += OnInitSuccess;
        LevelPlay.OnInitFailed += OnInitFailed;

        // Initialize the SDK with your App Key
        LevelPlay.Init(appKey);
    }

    private void OnInitSuccess(LevelPlayConfiguration config)
    {
        Debug.Log("LevelPlay SDK initialized successfully");
        // SDK is now ready to load ads
    }

    private void OnInitFailed(LevelPlayInitError error)
    {
        Debug.LogError($"LevelPlay initialization failed: {error.ErrorMessage}");
    }

    void OnDestroy()
    {
        LevelPlay.OnInitSuccess -= OnInitSuccess;
        LevelPlay.OnInitFailed -= OnInitFailed;
    }
}

File location: Save as Assets/Scripts/LevelPlayInitializer.cs (or Assets/Scripts/Ads/LevelPlayInitializer.cs if you have an Ads subfolder)

After creating:

Attach script to a GameObject in your first scene
In Unity Inspector, find the "App Key" field
Paste your App Key from Step 5 into that field

If the user answered Yes or Not Sure to ILRD in Step 7, wire up impression-level revenue. How you subscribe depends on the SDK version — check it in Ads Mediation > Network Manager:

SDK 9.5.0+ (current): subscribe per ad instance using OnAdImpressionDataReady on each ad object (rewarded, interstitial, banner) when you create it — not here in the initializer. The global event below is deprecated on 9.5.0+ and generates a compiler warning. See references/ilrd-api.md for the per-instance setup, then skip the snippet below.
SDK 9.4.x and earlier: use the global event below, registered before LevelPlay.Init().

For SDK 9.4.x and earlier, add these lines inside Start() (before LevelPlay.Init(appKey)):

// SDK 9.4.x and earlier only. On 9.5.0+ use per-instance OnAdImpressionDataReady instead.
// Recommended: register as early as possible, before LevelPlay.Init(). Subscribing in
// OnInitSuccess also works, since impressions only fire after an ad is shown.
// Callback fires on a BACKGROUND thread — see references/ilrd-api.md for
// thread-safe forwarding patterns and a Firebase example.
LevelPlay.OnImpressionDataReady += OnImpressionDataReady;

Add this stub method to the class:

private void OnImpressionDataReady(LevelPlayImpressionData impressionData)
{
    // See references/ilrd-api.md for full implementation.
    // For now, just log so you can verify it fires:
    Debug.Log($"ILRD: {impressionData.AdNetwork} / {impressionData.AdFormat} / ${impressionData.Revenue}");
}

And unsubscribe in OnDestroy():

LevelPlay.OnImpressionDataReady -= OnImpressionDataReady;

Next: Once you confirm the log fires after your first ad impression, read references/ilrd-api.md to wire it up to your actual analytics platform. Note: ILRD callbacks do not fire with mock ads in the Unity Editor — you'll need a device build to verify this log fires (see Step 10).

Option 2: Adding to Existing Script

If adding to an existing script (e.g., GameManager.cs):

1. Add namespace at top of file:

using Unity.Services.LevelPlay;

2. In existing Start() or Awake() method, add initialization:

void Start()
{
    // Register initialization callbacks
    LevelPlay.OnInitSuccess += OnInitSuccess;
    LevelPlay.OnInitFailed += OnInitFailed;

    // Initialize the SDK - REPLACE with your actual App Key from Step 5
    LevelPlay.Init("YOUR_APP_KEY_HERE");

    // ... your other existing Start() code
}

3. Add callback methods to class:

private void OnInitSuccess(LevelPlayConfiguration config)
{
    Debug.Log("LevelPlay SDK initialized successfully");
    // SDK is ready - you can now create ad objects
}

private void OnInitFailed(LevelPlayInitError error)
{
    Debug.LogError($"LevelPlay initialization failed: {error.ErrorMessage}");
}

4. In existing OnDestroy() (or create if it doesn't exist), add:

void OnDestroy()
{
    // Unregister callbacks
    LevelPlay.OnInitSuccess -= OnInitSuccess;
    LevelPlay.OnInitFailed -= OnInitFailed;
}

If the user answered Yes or Not Sure to ILRD in Step 7, wire up ILRD following the version-aware guidance in Option 1 above — per ad instance via OnAdImpressionDataReady on SDK 9.5.0+, or the global event before LevelPlay.Init(...) (with a stub handler and unsubscribe in OnDestroy()) on SDK 9.4.x and earlier.

Replace "YOUR_APP_KEY_HERE" with your actual App Key from Step 5 (the alphanumeric string copied from the LevelPlay dashboard).

Note: If your existing script doesn't already persist across scenes, add DontDestroyOnLoad(gameObject); to its Awake() method to prevent re-initialization when loading new scenes.

Before testing, double-check that you've replaced the placeholder with your actual App Key. The App Key should be an alphanumeric string, NOT 'YOUR_APP_KEY_HERE'.

Option 3: Separate Script Called by Manager

If you want to keep ads code in its own script but have your existing manager control initialization:

1. Create LevelPlayInitializer.cs using the complete class code from Option 1

2. In existing manager script (e.g., GameManager.cs), add:

using UnityEngine;

public class GameManager : MonoBehaviour
{
    void Awake()
    {
        // Add LevelPlay initialization as a component
        gameObject.AddComponent<LevelPlayInitializer>();

        // ... your other initialization code
    }
}

This keeps ad code isolated in LevelPlayInitializer.cs while GameManager controls when it initializes.

Note: LevelPlayInitializer.Awake() calls DontDestroyOnLoad(gameObject), which will mark this entire GameObject — including your GameManager and any other components on it — as persistent across scenes. Ensure this is compatible with your scene management strategy.

If the user answered Yes or Not Sure to ILRD in Step 7, wire up ILRD following the version-aware guidance in Option 1 above (on SDK 9.5.0+ the per-instance subscriptions live in the ad manager classes, not LevelPlayInitializer.cs). No changes needed in GameManager.

Before testing, ensure you've entered your actual App Key in the Unity Inspector's App Key field on the LevelPlayInitializer component (see Option 1's After Creating steps above).

Option 4: Just Show Me the Code

Provide the complete initialization code from Option 1 as a standalone snippet, without instructions for attaching to a GameObject or setting up the Inspector. Include a note: "This is the full initialization class — save it as LevelPlayInitializer.cs, attach it to a persistent GameObject in your first scene, and set the App Key field in the Inspector."

Key points:

Always register OnInitSuccess and OnInitFailed callbacks before calling Init()
Call initialization early in app lifecycle (in Awake() or Start() of first scene)
Only initialize once. If initialization script is in first scene and you have multiple scenes, add DontDestroyOnLoad(gameObject); in Awake() to prevent re-initialization when loading new scenes
Wait for OnInitSuccess before creating ad objects

If initialization fails repeatedly, see the Common Issues section for troubleshooting. Common causes include incorrect App Key, no internet connection, or missing package dependencies.

For more advanced initialization options (user ID, consent management, etc.), see references/initialization-api.md.

8. Recommend Ad Unit Strategy

Based on the optimization goal identified in Step 2, recommend an ad unit strategy.

Recall the user's optimization goal from Step 2. If the conversation has been long or the answer is unclear, confirm: "Earlier you mentioned your optimization goal. To confirm, are you primarily focused on revenue, user experience, or a balance of both?"

Map the answer to the appropriate strategy:

User focused on maximizing revenue, impressions, or monetization → Use Revenue-Focused Strategy
User focused on user experience, retention, or avoiding annoyance → Use UX-Focused Strategy
User wants to balance both or mentioned both revenue and UX → Use Balanced Strategy
User answered "Not sure yet" in Step 2 → Use Balanced Strategy. After presenting the recommendation, add: "Since you weren't sure of your goal earlier, I've gone with the Balanced approach — if you'd prefer to lean more toward revenue or user experience now that you've seen the options, just say so."
If unclear, ask: "Would you prioritize revenue, user experience, or a balance of both?"

Revenue-Focused Strategy

Goal: Maximize ad revenue and impression opportunities

Recommended ad units:

Rewarded ads: Primary monetization driver
- Implement in multiple high-value moments
- Use for premium rewards, extra lives, bonus content
- Load ads proactively to ensure availability
Interstitial ads: Secondary revenue source
- Show at natural transition points (level complete, game over)
- Frequency cap: Every 3-5 minutes of gameplay (see references/interstitial-api.md)
Banner ads: Persistent revenue during gameplay
- Show during core gameplay loops
- Use smart positioning to avoid UI conflicts

Revenue lever: bid floor (optional)

Once ads are live, bid floors let you set a minimum bid price per ad unit — raising your average eCPM at the cost of lower fill rate. You'll be prompted in Step 9 to configure this or skip and add it later.

Implementation priority: Rewarded → Interstitial → Banner

The next step will ask you to choose which ad formats to implement from this priority list.

UX-Focused Strategy

Goal: Maintain excellent user experience while monetizing thoughtfully

Recommended ad units:

Rewarded ads: Primary and often only ad format
- User-initiated only (explicit opt-in)
- High-value rewards that feel generous
- No forced ads, ever
Interstitial ads: Optional, sparingly used
- Only at major session boundaries (e.g., exiting to main menu)
- Never interrupt active gameplay
Banner ads: Generally avoided or minimized
- If used, only during menu screens, not gameplay
- Small, non-intrusive sizes

Implementation priority: Rewarded only, or Rewarded → (optional) Interstitial

The next step will ask you to choose which ad formats to implement from this priority list.

Balanced Strategy

Goal: Optimize both revenue and user satisfaction

Recommended ad units:

Rewarded ads: Core monetization
- 2-3 strategic placements in high-engagement moments
- Rewards feel valuable but not exploitative
Interstitial ads: Moderate usage
- At natural breakpoints (level transitions, session ends)
- Frequency cap: Every 5-7 minutes (see references/interstitial-api.md)
Banner ads: Selective placement
- Show in menus or low-attention moments
- Hide during intense gameplay

Implementation priority: Rewarded → Interstitial → Banner (selective)

The next step will ask you to choose which ad formats to implement from this priority list. If the user wants to implement in a different order than recommended, accommodate that preference.

9. Implement Ad Units

Important: Read Best Practices First

Before implementing ad code, read the Best Practices section below (after Step 10). It contains essential patterns for loading strategy, error handling, memory management, and placement strategy. These patterns should be incorporated into all ad implementations.

Implementation checkpoint:

Before implementing ad units, confirm:

"Before providing ad implementation code, please confirm:

Did you complete SDK initialization in Step 7?
Did you receive the 'LevelPlay SDK initialized successfully' log message in your Unity console?

Verify initialization is working before proceeding with ad units."

If they answer NO or are unsure:

Direct back to Step 7 to complete initialization first
Do not provide ad implementation code until initialization is confirmed working

If they answer YES, proceed with ad implementation.

Ad format checkpoint — ask before generating any code: "Which ad formats do you want to implement? Rewarded, Interstitial, Banner, or a combination?" Only implement the formats the user selects. They can add more formats later using the 'Adding More Ad Formats Later' section.

Based on the chosen strategy, implement the appropriate ad formats.

Implementation flexibility: Implement formats one at a time or all at once. Choose which formats you want to implement now, and you can always add more formats later (see 'Adding More Ad Formats Later' section below).

First, ask the user how they want to organize the ad code. Do not generate any code until they have answered:

"How would you like to structure your ad implementation?"

Separate manager scripts for each ad format - Create individual scripts like RewardedAdManager.cs, InterstitialAdManager.cs, BannerAdManager.cs (good for larger projects, clear separation of concerns)
One unified AdManager script - Create a single AdManager.cs that handles all ad formats (simpler, everything in one place)
Just show me the code snippets - Provide implementation code without wrapping it in specific files, so you can integrate it however you prefer
I already have ad manager code - Review and help fix/update existing implementation

Based on their answer, adapt your response accordingly.

Then present the optional bid floor feature (skip for Option 4 — review existing code instead):

Present bid floor ranges only for the formats the user is implementing in this session. Reference starting ranges: Rewarded: $0.50–$2.00 | Interstitial: $0.20–$1.00 | Banner: $0.05–$0.20. Include only the ranges for formats being implemented.

"Optional — Advanced: Bid Floors

Most publishers skip this initially and add it once they have real dashboard data. You can safely skip now and return to it later.

If you'd like to set bid floors now: a bid floor sets a minimum bid price (USD) per ad unit — it raises your average eCPM at the cost of lower fill rate. Starting ranges: [ranges for formats being implemented]

Reply with values per format, or just say 'skip' — you can add them any time."

Record the answer per format. Wire Config.Builder().SetBidFloor(...) into the ad construction for any format where a value was provided. Formats marked 'skip' use the basic constructor.

If they choose Option 4 (existing code):

Ask: "Please share your existing ad manager code for review"
Wait for them to provide the code
Analyze the existing implementation:
- Check if they're using current LevelPlay Ad Unit API (LevelPlayRewardedAd, LevelPlayInterstitialAd, LevelPlayBannerAd)
- Identify if they're using deprecated IronSource.Agent APIs
- Check for proper callback registration/unsubscription
- Look for missing error handling or memory leaks
Provide specific guidance:
- If using deprecated APIs: "You're using the old IronSource.Agent API. Here's how to migrate to the new LevelPlay Ad Unit API:"
- If using current APIs with issues: "Your implementation looks good but I noticed [specific issues]. Here's how to fix them:"
- If implementation is correct: "Your implementation looks solid. Which additional ad formats would you like to add?"
Offer to either:
- Provide fixes as code snippets to integrate into existing files
- Suggest refactoring if the code has structural issues
When adding new formats after reviewing existing code, present the bid floor prompt scoped to those new formats only, confirm whether to match their existing code organization pattern or use a new one, then follow the same implementation guidelines as Options 1–3 above.

For each ad format, follow the implementation guidelines in detailed references:

Rewarded ads: See references/rewarded-api.md
Interstitial ads: See references/interstitial-api.md
Banner ads: See references/banner-api.md

General Implementation Pattern

All ad formats follow a similar lifecycle:

Load: Request an ad from LevelPlay
Listen: Register callbacks for ad events (loaded, failed, shown, clicked, closed)
Check readiness: Verify ad is ready before showing
Show: Display the ad to the user
Handle callbacks: Respond to user interactions and ad lifecycle events

Code Generation Guidelines

If the user mentions they have existing code, ask to see it before providing implementation guidance. This allows you to provide targeted fixes rather than generating new code from scratch.

Adapt output based on the user's chosen organization approach:

Option 1: Separate manager scripts

Create complete, production-ready .cs files for each ad format
Name them clearly: RewardedAdManager.cs, InterstitialAdManager.cs, BannerAdManager.cs
Include full class structure with proper namespaces
Each manager handles one ad format completely

Option 2: Unified AdManager

Create a single AdManager.cs file
Include methods and callbacks for all requested ad formats in one class
Use clear method naming to distinguish between formats (e.g., LoadRewardedAd(), LoadInterstitial())
Keep code organized with regions or comments separating each ad format

Option 3: Code snippets only

Provide focused code blocks without full class wrappers
Clearly label each snippet (e.g., "Rewarded Ad Initialization", "Interstitial Event Callbacks")
Explain where/how to integrate each snippet
Note any dependencies between snippets

Regardless of chosen approach, always include:

All manager classes must inherit from MonoBehaviour — required for Unity lifecycle methods (Start(), OnDestroy()) and to attach the script to a GameObject
After generating any manager script, instruct the user to attach it to a persistent GameObject in their scene (the same one as the initializer, with DontDestroyOnLoad)
For banner and interstitial managers, call DestroyAd() in OnDestroy() so ads are destroyed and memory is freed when the manager is destroyed
Rewarded and interstitial show paths check IsAdReady() before ShowAd(). If the game uses dashboard placements, also check the static IsPlacementCapped(placementName) — capping is configured per placement in the LevelPlay dashboard, and showing a capped placement fails
Proper event subscription and unsubscription (to avoid memory leaks)
Null checks and defensive programming
Debug logs for troubleshooting
Clear variable names that match LevelPlay conventions
Error handling and graceful degradation

Bid floor handling (per-format):

If the user provided a bid floor value for a format, wrap construction in Config.Builder().SetBidFloor(value).Build() and pass the config to the constructor.
If the user said 'skip' for that format, use the basic constructor (new LevelPlayRewardedAd(adUnitId)).
Apply per-format: a publisher may set a floor on rewarded but skip banner.

Example (with bid floor):

var config = new LevelPlayRewardedAd.Config.Builder()
    .SetBidFloor(0.80)
    .Build();
rewardedAd = new LevelPlayRewardedAd(adUnitId, config);

Example (skipped):

rewardedAd = new LevelPlayRewardedAd(adUnitId);

Impression Level Revenue Tracking: If the user answered Yes or Not Sure to ILRD in Step 7, the ILRD callback was wired up during setup (per ad instance on SDK 9.5.0+, or globally in the init script on SDK 9.4.x and earlier). See references/ilrd-api.md to forward the data to the analytics platform (Firebase, AppsFlyer, Adjust, Singular, or custom backend).

If the user said "No" to ILRD and wants to add it now, see references/ilrd-api.md — how you subscribe depends on the SDK version: per ad instance via OnAdImpressionDataReady on SDK 9.5.0+, or the global LevelPlay.OnImpressionDataReady (before LevelPlay.Init()) on SDK 9.4.x and earlier.

10. Testing and Validation

LevelPlay provides two validation approaches for different stages of development:

Early Development: Mock Ads in Unity Editor

For early iteration and callback testing, use mock ads in Unity Editor. Unity automatically provides mock ads when you press Play in the Editor - no special configuration needed.

How it works:

When you press Play in Unity Editor, Unity automatically provides mock ads - no special configuration needed. Mock ads work with ANY App Key and Ad Unit ID values (including dummy values like "test" or "editor"). However, recommend using real App Key and real Ad Unit IDs from the LevelPlay dashboard so you don't forget to update them before building to device.

Example setup (works in both Editor and device builds):

The same initialization code you wrote in Step 7 works in both Editor (with mock ads) and device builds (with real ads). For example:

// Initialize with your actual App Key (replace "abc123..." with yours)
// Mock ads work with any value, but use your real key to avoid forgetting to update it later
LevelPlay.Init("abc123youractualappkey");

Example for rewarded ads (works in both Editor and device):

// In OnInitSuccess callback:
// Use your real ad unit ID from LevelPlay dashboard (replace "12345..." with yours)
// Mock ads work with any value, but use your real IDs to avoid forgetting to update them later
LevelPlayRewardedAd rewardedAd = new LevelPlayRewardedAd("12345youractualadunitid");
rewardedAd.OnAdLoaded += OnAdLoaded;
rewardedAd.OnAdRewarded += OnAdRewarded;
rewardedAd.LoadAd();

Key points:

Mock ads work with any App Key/Ad Unit ID values (you can even use "test" or "editor")
Recommended: Use your real credentials from Step 5 to avoid forgetting to update them later
Mock ads appear automatically when testing in Unity Editor
Real ads appear automatically when building to device
Same code works everywhere - no switching or conditional compilation needed
Android API 33+: If targeting Android 13+ devices, verify you've added the AD_ID permission to AndroidManifest.xml (see Step 4)

What mock ads validate:

Ad integration flow works correctly
Most callbacks fire as expected (see callback behavior below)
Ad loading, showing, and closing logic
Ad positioning and layout (for banners)
Basic ad logic and state management

Mock ad callback behavior:

Mock ads in Unity Editor fire most callbacks, but not all:

Callbacks that FIRE:

OnAdLoaded - Always fires after LoadAd()
OnAdDisplayed - Fires when ShowAd() is called
OnAdRewarded - Fires for rewarded ads (with test reward)
OnAdClosed - Fires when mock ad is dismissed

Callbacks that DON'T fire:

OnAdLoadFailed - Mock ads always succeed loading
OnAdDisplayFailed - Mock ads always succeed showing
OnAdClicked - Mock ads don't simulate user clicks
OnAdExpanded / OnAdCollapsed - Banner expand/collapse not simulated
OnAdLeftApplication - No real ad redirect in Editor
OnAdInfoChanged - Mock ads don't update ad info dynamically
ILRD impression callback (OnAdImpressionDataReady on 9.5.0+, or global LevelPlay.OnImpressionDataReady on 9.4.x and earlier) - No impression data generated in Editor

This means you can test your happy-path flow in Editor, but must test error handling on real devices.

Note on SDK initialization in the Editor: LevelPlay.OnInitSuccess may not fire in all SDK configurations when running in the Unity Editor. If your initialization callback doesn't trigger and your ad objects never load as a result, try creating them directly in Start() after calling LevelPlay.Init() rather than waiting for the callback — mock ads will appear even without OnInitSuccess firing.

Mock ads limitations:

Don't simulate network latency or failures
Don't test real ad network behavior
Don't validate reward logic server-side
Placeholder UI instead of real ad creatives
Error callbacks never fire

Best for: Early development, rapid iteration on ad logic, callback testing

Integration Validation: LevelPlay Test Suite (Recommended)

The Test Suite is the primary method for comprehensive validation. It tests your integration with real ad networks on device.

What Test Suite validates:

All ad formats (Rewarded, Interstitial, Banner) with real ads
SDK initialization with production App Key
All callbacks fire correctly in production environment
Real ad network behavior, latency, and edge cases
Ad rendering and user interaction flows

Before running the Test Suite:

Unity Ads is pre-installed — the Ads Mediation package includes the Unity Ads adapter by default, so you have at least one network ready without any additional setup. For ads to fill on device, verify your LevelPlay dashboard has active instances configured for your ad units.
Enable Development Build in Build Profiles (called Build Settings in Unity versions before Unity 6) before building to device. Without it, SDK console output won't be visible, making it very difficult to diagnose issues if something doesn't work as expected.

Setup (requires device build):

Add these two lines to your existing LevelPlayInitializer.cs — do not create a new file or replace your existing initializer:

At the top of Start(), before LevelPlay.Init(appKey):

LevelPlay.SetMetaData("is_test_suite", "enable");

Inside your OnInitSuccess callback:

LevelPlay.LaunchTestSuite();

Important: Remove both lines before your production release. Test Suite should only be used during development and testing.

Don't have a LevelPlayInitializer.cs yet? Use this complete template:

using UnityEngine;
using Unity.Services.LevelPlay;

public class LevelPlayInitializer : MonoBehaviour
{
    [SerializeField] private string appKey;

    void Awake()
    {
        DontDestroyOnLoad(gameObject);
    }

    void Start()
    {
        // Enable Test Suite — REMOVE before production release
        LevelPlay.SetMetaData("is_test_suite", "enable");

        LevelPlay.OnInitSuccess += OnInitSuccess;
        LevelPlay.OnInitFailed += OnInitFailed;
        LevelPlay.Init(appKey);
    }

    private void OnInitSuccess(LevelPlayConfiguration config)
    {
        Debug.Log("LevelPlay initialized successfully");
        // Launch Test Suite — REMOVE before production release
        LevelPlay.LaunchTestSuite();
    }

    private void OnInitFailed(LevelPlayInitError error)
    {
        Debug.LogError($"LevelPlay initialization failed: {error.ErrorMessage}");
    }

    void OnDestroy()
    {
        LevelPlay.OnInitSuccess -= OnInitSuccess;
        LevelPlay.OnInitFailed -= OnInitFailed;
    }
}

After creating this script:

Attach it to a GameObject in your first scene
In the Unity Inspector, find the "App Key" field
Paste your App Key from Step 5 into that field

Key points:

LevelPlay.SetMetaData("is_test_suite", "enable"); must be called BEFORE LevelPlay.Init() — if the Test Suite doesn't appear after launch, this is the most likely cause
LevelPlay.LaunchTestSuite(); is called AFTER successful initialization (in OnInitSuccess)
Requires device build - Test Suite does not work in Unity Editor
Use production App Key, not "editor"
Build to Android or iOS device and run the app
Test Suite UI will appear automatically after initialization

Testing workflow:

Add Test Suite code (SetMetaData before Init, LaunchTestSuite after OnInitSuccess)
Build to Android or iOS device
Run the app on device
Test Suite UI launches automatically
Follow on-screen instructions to test each ad format
Verify all ad formats load and callbacks fire correctly

Best for: Integration validation before production, final testing with real ad networks

Production Release Checklist

Before releasing to production:

Adding More Ad Formats Later

If you've already integrated some ad formats and want to add more:

Skip to Step 9 - You don't need to repeat the initial setup steps. Before proceeding, verify your existing initialization still works by checking the Unity console for the 'LevelPlay SDK initialized successfully' log.
Choose the additional formats you want to implement
Follow the same organization pattern you used before:
- If you created separate manager scripts, create a new manager script for the new format
- If you used a unified AdManager, add the new format's code to your existing AdManager class
- If you used code snippets, integrate new snippets following the same pattern
Follow the same implementation guidelines from Step 9 for the new ad format
Test the new format following Step 10 testing guidelines

Example: If you initially implemented only Rewarded ads using separate manager scripts, and now want to add Interstitial ads:

Create InterstitialAdManager.cs following the same structure as your RewardedAdManager.cs
Follow the interstitial implementation guidelines from references/interstitial-api.md
Test the interstitial ads in Unity Editor and on device

Your existing ad formats will continue to work while you add new ones. You can add formats incrementally without disrupting your current implementation.

Best Practices

Loading Strategy

Rewarded Ads:

LoadAd() must be called explicitly — the SDK no longer auto-manages loading as it did in the legacy IronSource API
Create the ad object and subscribe events in OnInitSuccess; trigger LoadAd() from a publisher-controlled point (a button, scene entry, or gameplay moment)
Reloading after close is optional and publisher-controlled, not automatic; see references/rewarded-api.md for both the explicit and eager preload patterns

Interstitial Ads:

Load proactively before natural break points
Maintain a loaded interstitial for opportunistic moments
Reload after showing

Banner Ads:

Load when entering scenes where banners will be displayed
Destroy banners when leaving those scenes to free memory

Placement Strategy

Align ad placements with user engagement moments:

High engagement (post-victory, level up): Best for rewarded ads
Natural transitions (level complete, menu navigation): Good for interstitials
Low attention (waiting periods, menus): Acceptable for banners

Error Handling

Always handle ad load failures gracefully:

private void OnAdLoadFailed(LevelPlayAdError error)
{
    Debug.LogWarning($"Ad failed to load: {error.ErrorMessage}");

    // Retry loading after a delay
    Invoke(nameof(LoadAd), 30f); // Retry in 30 seconds

    // Provide fallback UX if ad was requested by user
    // Don't leave users stuck waiting for an ad that won't load
}

Memory Management

Properly unsubscribe from events to prevent memory leaks:

void OnDestroy()
{
    // Unsubscribe from all LevelPlay events
    if (rewardedAd != null)
    {
        rewardedAd.OnAdLoaded -= OnAdLoaded;
        rewardedAd.OnAdLoadFailed -= OnAdLoadFailed;
        // ... unsubscribe from all other events
    }
}

Common Issues and Solutions

Note: This section addresses issues that can occur during integration. If you haven't started the integration yet, begin with Step 1: Verify Environment.

Issue: CS0246 - Type or namespace 'Unity.Services.LevelPlay' not found

Root cause: Ads Mediation package not installed in Unity project

Symptoms:

Compiler errors: The type or namespace name 'LevelPlay' could not be found
Compiler errors: The type or namespace name 'Unity.Services.LevelPlay' could not be found
Red underlines in Unity Editor on all LevelPlay code

Solutions:

Stop providing code immediately
Ask: "Can you confirm the Ads Mediation package is installed? Check Window > Package Manager and verify 'Ads Mediation' appears under 'Packages: In Project'"
If not installed, direct to Step 3 to install via Unity Package Manager
Have them restart Unity Editor after installation (important!)
Verify installation by checking that using Unity.Services.LevelPlay; no longer shows errors
Only resume code generation after confirmation and verification

Prevention: Always verify package installation at Step 7 checkpoint before generating any code.

Issue: Android gradle build fails / iOS build fails with dependency errors

Root cause: Native dependencies not resolved

Symptoms:

Android: Gradle build errors mentioning missing dependencies or classes
iOS: CocoaPods errors, missing frameworks, or linker errors
Code compiles perfectly in Unity Editor but fails during platform build
Build succeeds in Editor but crashes immediately on device

Solutions:

Verify you have a dependency manager installed (Mobile Dependency Resolver, Unity External Dependency Manager, or EDM4U)
Check your project's Assets folder for dependency manager tools
Run dependency resolution:
- Android (newer MDR versions): Should auto-resolve on build. If failing, manually resolve via Assets > Mobile Dependency Resolver > Android Resolver > Resolve
- Android (older/other managers): Assets > [Your Dependency Manager] > Android Resolver > Resolve
- iOS (all managers): Assets > [Your Dependency Manager] > iOS Resolver > Install Cocoapods
Verify resolution:
- Android: Check Assets/Plugins/Android/ for gradle files
- iOS: Look for Podfile or CocoaPods confirmation in console
If you don't have a dependency manager, restart Unity - you should see a prompt to install Mobile Dependency Resolver
Rebuild for your target platform after resolution

Prevention: Complete Step 4 (dependency resolution) before building for Android/iOS.

Issue: Ads not loading

Possible causes:

SDK not initialized before loading ads
Incorrect App Key
Ad object created before initialization completes
Network connectivity issues
Ad inventory not available in test region

Solutions:

Verify LevelPlay.Init() is called and OnInitSuccess fires before creating ad objects
Create ad objects only after OnInitSuccess callback
Check App Key matches LevelPlay dashboard
Test on real devices with active internet connection
Enable test mode in LevelPlay dashboard for guaranteed test ads (Note: dashboard test mode is separate from mock ads in the Unity Editor — it enables real test ads on device)

Issue: Callbacks not firing

Possible causes:

Events registered after SDK initialization
Missing event subscriptions
Script destroyed before callbacks execute

Solutions:

Register callbacks before calling Init()
Verify all callbacks are subscribed (check with Debug.Log statements)
Use persistent GameObject with DontDestroyOnLoad if needed

Issue: Platform-specific build errors

iOS:

Ensure SKAdNetwork IDs are configured in Info.plist
Verify ATT is implemented correctly (see references/ios-setup.md)
Check Xcode build settings for required frameworks

Android:

Verify Google Play Services is included
Check AndroidManifest.xml for required permissions
Ensure Gradle dependencies are resolved
