Data Layer Overview

All static game data lives in pytemon/data/:

Helper accessors live in data/__init__.py:

from pytemon.data import get_pokemon, get_move, get_trainer

Pokemon Data Structure (POKEMON)

"PIKACHU": {
    "number": 25,
    "name": "PIKACHU",
    "types": ["Electric"],
    "base_stats": {
        "hp": 35, "attack": 55, "defense": 30,
        "special": 50, "speed": 90
    },
    "base_moves": ["THUNDER SHOCK", "GROWL"],
    "learnset": {
        9: "THUNDER WAVE", 26: "SWIFT", 33: "AGILITY"
    },
    "evolution": {
        "method": "item",
        "item": "Thunder Stone",
        "into": "RAICHU"
    },
    "catch_rate": 190,
    "base_exp": 82,
    "description": "It stores static electricity in its cheeks.",
}

Move Data Structure (MOVES)

"THUNDER SHOCK": {
    "name": "THUNDER SHOCK",
    "type": "Electric",
    "category": "Special",   # "Physical" | "Special" | "Status"
    "power": 40,
    "accuracy": 100,
    "pp": 30,
    "effect": "paralysis",           # optional
    "effect_chance": 10,             # optional (0-100)
    "description": "A jolt of electricity.",
}

Effect values: "paralysis", "sleep", "poison", "bad_poison", "burn", "freeze", "flinch", "raise_attack", "lower_defense" — see battle_engine.py for the full list.

Locations (locations.py)

Each location is a Location dataclass:

@dataclass
class Location:
    name: str
    location_type: str   # "town" | "route" | "city" | "dungeon"
    connected_to: list[str]
    wild_pokemon: list[dict]   # [{"species": "RATTATA", "min_level": 2, "max_level": 5}]
    description: str
    has_pokemon_center: bool = False
    has_pokemart: bool = False
    gym_leader: str | None = None

LOCATIONS dict is the registry. get_location(name) returns the Location or None.

Navigation rules:

• Only connected locations can be moved to directly
• Towns/cities are hubs; routes connect them
• can_move_to(current, destination, game_data) checks badges/story flags too

Trainers (trainer_data.py)

Trainer(
    id="youngster_joey",
    name="Joey",
    trainer_class="Youngster",
    location="Route 1",
    pokemon=[
        TrainerPokemon(species="RATTATA", level=4),
    ],
    prize_money=80,
    intro_text=["My Rattata is top percentage!"],
    defeat_text=["Aw man!"],
    victory_text=["I won!"],
    badge_reward="",   # empty unless this is a gym leader
    badge_id="",
)

Gym leader trainers have trainer_class="Gym Leader" and non-empty badge_reward/badge_id.

Gyms (gym_system.py)

GYMS dict maps city name → gym config:

"Pewter City": {
    "badge": "Boulder Badge",
    "badge_id": "boulder",
    "specialty": "Rock",
    "leader_id": "brock",
    "trainers": ["pewter_trainer_1"],
    "min_badges": 0,
}

can_challenge_gym(gs, location) returns (bool, reason_str). award_badge(gs, badge_name, output) grants the badge.

Evolution (evolution.py)

Evolution conditions supported:

# By level
"evolution": {"method": "level", "level": 16, "into": "IVYSAUR"}

# By item
"evolution": {"method": "item", "item": "Fire Stone", "into": "ARCANINE"}

# By trade
"evolution": {"method": "trade", "into": "ALAKAZAM"}

check_evolution(pokemon) returns (can_evolve: bool, into: str | None, method: str). perform_evolution(gs, pokemon, output) does the actual evolution.

Adding New Content

New Pokemon

1. Add entry to POKEMON in data/pokemon_data.py
2. If it has evolutions, ensure both pre- and post-evolution are in POKEMON
3. Add to wild encounter tables in LOCATIONS if it appears in the wild

New Move

1. Add entry to MOVES in data/move_data.py
2. Add to relevant Pokemon's base_moves or learnset
3. If it has a new effect type, handle it in BattleState.apply_status_effect

New Location

1. Add Location instance to LOCATIONS in locations.py
2. Add the name to connected_to on adjacent locations (bidirectional)
3. Add wild Pokemon if it's a route

New Gym Leader

1. Add Trainer with trainer_class="Gym Leader" to trainer_data.py
2. Add gym entry to GYMS in gym_system.py
3. Set badge_reward and badge_id on the Trainer

Common Checks

# Check if a pokemon can evolve
from pytemon.evolution import check_evolution
can, into, method = check_evolution(pokemon)

# Check if a location exists
from pytemon.locations import get_location
loc = get_location("Cerulean City")   # None if not found

# Check if a move exists
from pytemon.data import get_move
move = get_move("SURF")   # None if not in MOVES

# Check if a trainer exists
from pytemon.data import get_trainer
trainer = get_trainer("brock")
