Unity Editor Control Skill

You are an expert Unity developer. This skill enables you to directly control Unity Editor through a REST API. Use the Python helper script in scripts/unity_skills.py to execute Unity operations.

Prerequisites

1. Unity Editor must be running with the UnitySkills package installed
2. REST server must be started: Window > UnitySkills > Start Server
3. Server endpoint: http://localhost:8090

Quick Start

# Import the helper from the scripts/ directory
import sys
sys.path.insert(0, 'scripts')  # Adjust path to skill's scripts directory
from unity_skills import call_skill, is_unity_running, wait_for_unity

# Check if Unity is ready
if is_unity_running():
    # Create a cube
    call_skill('gameobject_create', name='MyCube', primitiveType='Cube', x=0, y=1, z=0)
    # Set its color to red
    call_skill('material_set_color', gameObjectName='MyCube', r=1, g=0, b=0)

⚠️ Important: Script Creation & Domain Reload

When creating C# scripts with script_create, Unity recompiles all scripts (Domain Reload). The server temporarily stops during compilation and auto-restarts.

# After creating a script, wait for Unity to recompile
result = call_skill('script_create', name='MyScript', template='MonoBehaviour')
if result.get('success'):
    wait_for_unity(timeout=10)  # Wait for server to come back

Workflow Examples

Create a Game Scene

# 1. Create ground
call_skill('gameobject_create', name='Ground', primitiveType='Plane', x=0, y=0, z=0)
call_skill('gameobject_set_transform', name='Ground', scaleX=5, scaleY=1, scaleZ=5)

# 2. Create player
call_skill('gameobject_create', name='Player', primitiveType='Capsule', x=0, y=1, z=0)
call_skill('component_add', name='Player', componentType='Rigidbody')

# 3. Add lighting
call_skill('light_create', name='Sun', lightType='Directional', intensity=1.5)

# 4. Save the scene
call_skill('scene_save', scenePath='Assets/Scenes/GameScene.unity')

Create UI Menu
