WebGLBufferWrapper

Phaser.Renderer.WebGL.Wrappers.WebGLBufferWrapper

Wrapper for a WebGL buffer, containing all the information that was used to create it. This can be a VertexBuffer or IndexBuffer.

A WebGLBuffer should never be exposed outside the WebGLRenderer, so the WebGLRenderer can handle context loss and other events without other systems having to be aware of it. Always use WebGLBufferWrapper instead.

Constructor

new WebGLBufferWrapper(gl, initialDataOrSize, bufferType, bufferUsage)

Parameters

name

type

optional

description

gl

WebGLRenderingContext

No

The WebGLRenderingContext to create the WebGLBuffer for.

initialDataOrSize

ArrayBuffer | number

No

Either an ArrayBuffer of data, or the size of the buffer to create.

bufferType

GLenum

No

The type of the buffer being created.

bufferUsage

GLenum

No

The usage of the buffer being created. gl.DYNAMIC_DRAW, gl.STATIC_DRAW or gl.STREAM_DRAW.

initialDataOrSize

initialDataOrSize: ArrayBuffer, number

Description:

The initial data or size of the buffer.

Note that this will be used to recreate the buffer if the WebGL context is lost.

webGLBuffer

webGLBuffer: WebGLBuffer

Description:

The WebGLBuffer being wrapped by this class.

This property could change at any time. Therefore, you should never store a reference to this value. It should only be passed directly to the WebGL API for drawing.

Public Methods

createResource

<instance> createResource()

Description:

Creates a WebGLBuffer for this WebGLBufferWrapper.

This is called automatically by the constructor. It may also be called again if the WebGLBuffer needs re-creating.

Since: 3.80.0


destroy

<instance> destroy()

Description:

Remove this WebGLBufferWrapper from the GL context.
