Properties

frameTime

frameTime: number = 0

The current frame time in milliseconds

Remarks

This is used to populate the lastRenderableChangeTime property of Texture instances when their renderable state changes.

Set by stage via updateFrameTime method.

hasCreateImageBitmap

hasCreateImageBitmap: boolean = !!self.createImageBitmap

hasWorker

hasWorker: boolean = !!self.Worker

imageBitmapSupported

imageBitmapSupported: {
    basic: boolean;
    full: boolean;
    options: boolean;
} = ...

imageWorkerManager

imageWorkerManager: null | ImageWorkerManager = null

inverseKeyCache

inverseKeyCache: WeakMap<Texture, string> = ...

Map of cache keys by texture

keyCache

keyCache: Map<string, Texture> = ...

Map of textures by cache key

renderer

renderer: CoreRenderer

Renderer that this texture manager is associated with

Remarks

This MUST be set before the texture manager is used. Otherwise errors will occur when using the texture manager.

txConstructors

txConstructors: Partial<TextureMap> = {}

Map of texture constructors by their type name
