constructor

new TextureSystem(renderer: Renderer): TextureSystem
Parameters
- renderer: Renderer
  The renderer this system works for.
Returns TextureSystem

Properties

`Readonly`boundTextures

boundTextures: BaseTexture<Resource, IAutoDetectOptions>[]

Bound textures.

`Readonly`currentLocation

currentLocation: number

Current location.

emptyTextures

emptyTextures: { [key: number]: GLTexture }

`Readonly`managedTextures

managedTextures: BaseTexture<Resource, IAutoDetectOptions>[]

List of managed textures.

Methods

bind

bind(
texture: BaseTexture<Resource, IAutoDetectOptions> | Texture<Resource>,
location?: number,
): void
Bind a texture to a specific location

If you want to unbind something, please use unbind(texture) instead of bind(null, textureLocation)
Parameters
- texture: BaseTexture<Resource, IAutoDetectOptions> | Texture<Resource>
  Texture to bind
- Optionallocation: number
  Location to bind at
Returns void

contextChange

contextChange(): void
Sets up the renderer context and necessary buffers.

Returns void

destroy

destroy(): void
Generic destroy methods to be overridden by the subclass

Returns void
Implementation of ISystem.destroy

ensureSamplerType

ensureSamplerType(maxTextures: number): void
Ensures that current boundTextures all have FLOAT sampler type, see PIXI.SAMPLER_TYPES for explanation.
Parameters
- maxTextures: number
  number of locations to check
Returns void

initTextureType

initTextureType(texture: BaseTexture, glTexture: GLTexture): void
Parameters
- texture: BaseTexture
- glTexture: GLTexture
Returns void

reset

reset(): void
Resets texture location and bound textures Actual bind(null, i) calls will be performed at next unbind() call

Returns void

unbind

unbind(texture?: BaseTexture<Resource, IAutoDetectOptions>): void
Unbind a texture.
Parameters
- Optionaltexture: BaseTexture<Resource, IAutoDetectOptions>
  Texture to bind
Returns void
