Methods

Private applyOpacity

Private createMeshBuffer

Private destroyUIMaterials

  • _destroyUIMaterials(): void

getUIMaterial

  • getUIMaterial(mat: Material): UIMaterial

Private postprocess

  • postprocess(node: Node): void

Private preprocess

  • preprocess(node: Node): void

Private recursiveScreenNode

  • recursiveScreenNode(screen: Node): void

removeUIMaterial

  • removeUIMaterial(hash: number): void

Private renderScreens

  • _renderScreens(): void

Private requireBufferBatch

  • _requireBufferBatch(): void

Private reset

  • _reset(): void

Private screenSort

Private walk

  • walk(node: Node, level?: number): void

addScreen

  • addScreen(comp: Canvas): void

autoMergeBatches

commitComp

  • UI 渲染组件数据提交流程（针对提交的顶点数据是世界坐标的提交流程，例如：除 Graphics 和 UIModel 的大部分 ui 组件）。 此处的数据最终会生成需要提交渲染的 model 数据。

    Parameters

    • comp: UIRenderable

      当前执行组件。

    • Default value frame: GFXTexture | null = null

      当前执行组件贴图。

    • assembler: any

      当前组件渲染数据组装器。

    • Default value sampler: GFXSampler | null = null

    Returns void

commitModel

  • UI 渲染组件数据提交流程（针对例如： Graphics 和 UIModel 等数据量较为庞大的 ui 组件）。

    Parameters

    Returns void

commitStaticBatch

destroy

  • destroy(): void

finishMergeBatches

  • finishMergeBatches(): void

forceMergeBatches

getRenderSceneGetter

  • getRenderSceneGetter(): get

getScreen

  • getScreen(visibility: number): null | Canvas

initialize

  • initialize(): boolean

removeScreen

  • removeScreen(comp: Canvas): void

render

  • render(): void

sortScreens

  • sortScreens(): void

update

  • update(dt: number): void
