buildTilemapAtlas
buildTilemapAtlas(
opts):TextureAtlasRegistry
Defined in: src/modules/tilemap/atlas.ts:29
Collects every unique GID across all visible tile layers, resolves each
to its source rectangle via gidToFrame, and registers the frames
under name in a new TextureAtlasRegistry.
The returned registry is ready to hand to
Canvas2DRenderContext.atlases. Callers that load multiple maps or
layer additional atlases on top can call registry.add(...) on the
result before passing it to the renderer.
The atlas is built synchronously — the image must already be loaded. Throws when the map has no tileset.
