# Class: Layer

Defined in: [layer.ts:24](https://github.com/debuffjp/debuff/blob/b018c1a068ef1bc6d0d897e130238baa96957244/packages/spryte/src/layer.ts#L24)

Sprites recorded once with `draw.record()` and drawn again with `draw.replay()`, for things that don't
change from frame to frame: a tilemap, a background, a level's scenery. On WebGL2 a replay is a few draw
calls however many sprites the layer holds, instead of the per-sprite work of drawing them again.

A layer keeps the sprite images it was recorded with. Change a tile, and record the layer again.

> **dispose**(): `void`

Defined in: [layer.ts:45](https://github.com/debuffjp/debuff/blob/b018c1a068ef1bc6d0d897e130238baa96957244/packages/spryte/src/layer.ts#L45)
