Entities can now specify per-tile sprite indices via the sprite_grid property. When set, each tile in a multi-tile entity renders its own sprite from the texture atlas instead of the single entity sprite. API: entity.tile_size = (3, 2) entity.sprite_grid = [[10, 11, 12], [20, 21, 22]] entity.sprite_grid = None # revert to single sprite Accepts nested lists, flat lists, or tuples. Use -1 for empty tiles. Dimensions must match tile_width x tile_height. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
