WebGLTextureWrapper

Wrapper for a WebGL texture, containing all the information that was used to create it.

A WebGLTexture 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 WebGLTextureWrapper instead.

Constructor

new WebGLTextureWrapper(renderer, mipLevel, minFilter, magFilter, wrapT, wrapS, format, pixels, width, height, [pma], [forceSize], [flipY])

Parameters

nametypeoptionaldefaultdescription
rendererPhaser.Renderer.WebGL.WebGLRendererNoThe WebGLRenderer instance that owns this wrapper.
mipLevelnumberNoMip level of the texture.
minFilternumberNoFiltering of the texture.
magFilternumberNoFiltering of the texture.
wrapTnumberNoWrapping mode of the texture.
wrapSnumberNoWrapping mode of the texture.
formatnumberNoWhich format does the texture use.
pixelsobjectNoThe pixel data used to populate the texture. Can be a Canvas, Video, ImageData, Uint8Array, or compressed texture object.

Public Members​

batchUnit​

batchUnit: number​

Description:

The texture unit this texture will be bound to in the current rendering batch.

This should be set by the batcher. It is a quick way to tell whether this texture has been included in the batch. If it is -1, it has not.

flipY​

flipY: boolean​

Description:

Sets the UNPACK_FLIP_Y_WEBGL flag the WebGL Texture uses during upload.

forceSize: boolean​

Description:

Whether to use the width and height properties, regardless of pixel dimensions.

Since: 3.80.0


format​

format: number​

Description:

The WebGL pixel format of the texture (e.g. gl.RGBA or gl.RGB).

Source: src/renderer/webgl/wrappers/WebGLTextureWrapper.js#L131
Since: 3.80.0


height​

height: number​

Description:

Height of the texture in pixels.

Source: src/renderer/webgl/wrappers/WebGLTextureWrapper.js#L158
Since: 3.80.0


isRenderTexture​

isRenderTexture: boolean​

Description:

Whether this is used as a RenderTexture.

Source: src/renderer/webgl/wrappers/WebGLTextureWrapper.js#L70
Since: 3.80.0


magFilter​

magFilter: number​

Description:

The magnification filter for the texture, as a WebGL filter constant (e.g. gl.LINEAR or gl.NEAREST). Applied when the texture is scaled up.

Source: src/renderer/webgl/wrappers/WebGLTextureWrapper.js#L100
Since: 3.80.0


minFilter​

minFilter: number​

Description:

The minification filter for the texture, as a WebGL filter constant (e.g. gl.LINEAR or gl.NEAREST). Applied when the texture is scaled down.

Source: src/renderer/webgl/wrappers/WebGLTextureWrapper.js#L89
Since: 3.80.0


mipLevel​

mipLevel: number​

Description:

Mip level of the texture.

Source: src/renderer/webgl/wrappers/WebGLTextureWrapper.js#L80
Since: 3.80.0


pixels​

pixels: object​

Description:

Pixel data. This is the source data used to create the WebGLTexture.

Source: src/renderer/webgl/wrappers/WebGLTextureWrapper.js#L140
Since: 3.80.0


pma​

pma: boolean​

Description:

Does the texture have premultiplied alpha?

Source: src/renderer/webgl/wrappers/WebGLTextureWrapper.js#L167
Since: 3.80.0


renderer​

renderer: Phaser.Renderer.WebGL.WebGLRenderer​

Description:

The WebGLRenderer this WebGLTexture belongs to.

Source: src/renderer/webgl/wrappers/WebGLTextureWrapper.js#L47
Since: 4.0.0


spectorMetadata​

spectorMetadata: object​

Description:

The __SPECTOR_Metadata property of the WebGLTexture, used to add extra data to the debug SpectorJS integration.

Source: src/renderer/webgl/wrappers/WebGLTextureWrapper.js#L418
Since: 3.80.0


webGLTexture​

webGLTexture: WebGLTexture​

Description:

The WebGLTexture that this wrapper is wrapping.

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.

Source: src/renderer/webgl/wrappers/WebGLTextureWrapper.js#L56
Since: 3.80.0


width​

width: number​

Description:

Width of the texture in pixels.

Source: src/renderer/webgl/wrappers/WebGLTextureWrapper.js#L149
Since: 3.80.0


wrapS​

wrapS: number​

Description:

The wrapping mode for the S (horizontal) axis of the texture, as a WebGL wrap constant (e.g. gl.REPEAT or gl.CLAMP_TO_EDGE).

Source: src/renderer/webgl/wrappers/WebGLTextureWrapper.js#L121
Since: 3.80.0


wrapT​

wrapT: number​

Description:

The wrapping mode for the T (vertical) axis of the texture, as a WebGL wrap constant (e.g. gl.REPEAT or gl.CLAMP_TO_EDGE).

Source: src/renderer/webgl/wrappers/WebGLTextureWrapper.js#L111

Public Methods​

_processTexture​

<instance> _processTexture()​

Description:

Set all parameters of this WebGLTexture per the stored values.

Access: protected

Source: src/renderer/webgl/wrappers/WebGLTextureWrapper.js#L342
Since: 4.0.0


createResource​

<instance> createResource()​

Description:

Creates a WebGLTexture from the given parameters.

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

Source: src/renderer/webgl/wrappers/WebGLTextureWrapper.js#L224
Since: 3.80.0


destroy​

<instance> destroy()​

Description:

Deletes the WebGLTexture from the GPU, if it has not been already.

Source: src/renderer/webgl/wrappers/WebGLTextureWrapper.js#L443
Since: 3.80.0


resize​

<instance> resize(width, height)​

Description:

Resizes the WebGLTexture to the new dimensions. This will destroy the contents of the texture.

Wrap mode will be updated: REPEAT if the new size is power-of-two, CLAMP_TO_EDGE if not.

Parameters:

nametypeoptionaldescription
widthnumberNoThe new width of the WebGLTexture.
heightnumberNoThe new height of the WebGLTexture.

Source: src/renderer/webgl/wrappers/WebGLTextureWrapper.js#L263
Since: 4.0.0


update​

<instance> update(source, width, height, flipY, wrapS, wrapT, minFilter, magFilter, format)​

Description:

Updates the WebGLTexture from an updated source.

This should only be used when the source is a Canvas or Video element.

Because textures usually change into something complex and unique, this method forces all properties to update without checking.

Parameters:

nametypeoptionaldescription
sourceobjectNoThe source to update the WebGLTexture with.
widthnumberNoThe new width of the WebGLTexture.
heightnumberNoThe new height of the WebGLTexture.
flipYbooleanNoShould the WebGLTexture set UNPACK_FLIP_Y_WEBGL?
wrapSnumberNoThe new wrapping mode for the WebGLTexture.
wrapTnumberNoThe new wrapping mode for the WebGLTexture.
minFilternumberNoThe new minification filter for the WebGLTexture.
magFilternumberNoThe new magnification filter for the WebGLTexture.
formatnumberNoThe new format for the WebGLTexture.
