description

Reviews Godot TileMap implementation for known pitfalls. Triggers AFTER implementation, when code involves TileMapLayer, TileSet, TileSetAtlasSource, TileSetScenesCollectionSource, terrain painting, set_cell, erase_cell, get_cell_tile_data, collision polygons on tiles, or NavigationRegion2D with tile-based navigation. Do NOT use this skill for planning or teaching — only for post-implementation review.

TileMap Review

Post-implementation reviewer for Godot TileMap code. Checks against known gotchas that LLMs consistently get wrong.

When to trigger

After TileMap-related code is written or modified. Look for:

• TileMapLayer, TileSet, TileSetAtlasSource, TileSetScenesCollectionSource nodes
• Cell operations (set_cell, erase_cell, set_cells_terrain_connect)
• TileData access (get_cell_tile_data)
• Collision/navigation polygon configuration on tiles
• y_sort_enabled on TileMapLayer
• NavigationRegion2D with TileMapLayer children

Review process

1. Read gotchas.md
2. Scan the implemented code against each gotcha
3. For each hit:
   • Cite the gotcha ID (e.g. G1)
   • Show the offending code
   • Provide the fix
4. If no hits, report clean
5. Optionally run checklist.md static checks for automated verification
