Methods

addRenderer

addRenderer<T, P>(id, rendererClass, params?, active?): Promise<T>
Add a renderer to this layer. It's constructed with the layer's own width/height, so callers pass only the class and its config - never dimensions.
Type Parameters
- T extends LayerRenderer<never>
- P = unknown
Parameters
- id: string
  unique id for this renderer within the layer
- rendererClass: (new (width, height, params?) => T)
  the renderer class (not an instance)
  - - new (width, height, params?): T
    - Parameters
      width: number
      height: number
      Optional params: P
      Returns T
- Optional params: P
  optional config forwarded to the renderer constructor
- active: boolean = true
  if true (default) the renderer is added to the render queue
Returns Promise<T>
the constructed, initialised renderer instance
Example
```
const shaky = await layer.addRenderer('shaky', ShakyRenderer, { mode: 'decay' })
  shaky.triggerShake()
```
Inherited from BaseLayer.addRenderer
- Defined in src/layers/base-layer.ts:133

removeRenderer

removeRenderer(id): void
Remove a renderer from this layer. If it was in the render queue, it will be removed from there too.
Parameters
- id: string
  Renderer id to remove. If not found, this is a no-op.
Returns void
Inherited from BaseLayer.removeRenderer
- Defined in src/layers/base-layer.ts:181

deactivateRenderer

deactivateRenderer(id): void
Pause a renderer without destroying it. The instance is kept and can be re-enabled with activateRenderer. Order in the queue is preserved.
Parameters
- id: string
  Renderer id to deactivate. No-op if not found or already inactive.
Returns void
Inherited from BaseLayer.deactivateRenderer
- Defined in src/layers/base-layer.ts:194

activateRenderer

activateRenderer(id): void
Re-enable a previously deactivated renderer, restoring it at its original position in the queue. The renderer must have been registered via the constructor renderers dict or addRenderer.
Parameters
- id: string
  Renderer id to activate.
Returns void
Throws
if the renderer is not registered on this layer.
Inherited from BaseLayer.activateRenderer
- Defined in src/layers/base-layer.ts:206
