TileLayer

Defined in: packages/three-flatland/src/tilemap/TileLayer.ts:260

A layer of tiles in a tilemap.

Splits tiles into regional chunks for frustum culling, each rendered as a single InstancedMesh with Sprite2DMaterial. Maps up to chunkSize×chunkSize tiles naturally collapse into one chunk (one draw call).

Example

const layer = new TileLayer(
  layerData,
  tileset,
  16, // tileWidth
  16, // tileHeight
)

scene.add(layer)

// In update loop
layer.update(deltaMs)

// Standard three.js material state is supported on the live layer material.
layer.material.opacity = 0.8

Register shader effects through TileMap2D.addEffect; direct colorNode assignments are replaced when the tile projection rebuilds.
