Texture

Texture 

Wrapper around a native texture data.

• Texture
  • .constructor(engine, param) ⇒ Texture
  • .engine
  • .height
  • .id
  • .valid
  • .width
  • .destroy() ⇒ void
  • .equals(otherTexture) ⇒ boolean
  • .update() ⇒ void
  • .updateSubImage(x, y, w, h) ⇒ void

.constructor(engine: WonderlandEngine, param: number | HTMLCanvasElement | HTMLImageElement | HTMLVideoElement) ⇒ Texture 

.engine 

Hosting engine instance.

.height 

Height of the texture.

.id 

Index in this manager.

.valid 

Whether this texture is valid.

.width 

Width of the texture.

.destroy() ⇒ void 

Destroy and free the texture’s texture altas space and memory.

It is best practice to set the texture variable to null after calling destroy to prevent accidental use of the invalid texture:

1
2

  texture.destroy();
  texture = null;

.equals(otherTexture: undefined | null | Texture) ⇒ boolean 

Checks equality by comparing whether the wrapped native texture ids are equal.

Returns: Whether this texture equals the given texture.

.update() ⇒ void 

Update the texture to match the HTML element (e.g. reflect the current frame of a video).

.updateSubImage(x: number, y: number, w: number, h: number) ⇒ void 

Update a subrange on the texture to match the HTML element (e.g. reflect the current frame of a video).

Usage:

// Copies rectangle of pixel starting from (10, 20)
texture.updateSubImage(10, 20, 600, 400);
