# 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 When you need specific API details, delegate to the **godot-api** skill.
