enchant.gl.Shader(vshader, fshader)

Class to control WebGL shader program. A shader program will be created by delivering the vertex shader source and fragment shader source.

{String} fShaderSource

Fragment shader source

{String} vShaderSource

Vertex shader source

compile()

Compile shader program. Will be automatically compiled when shader source is delivered from constructor.

var shader = new Shader();
// Deliver shader program source.
shader.vShaderSource = vert;
shader.fShaderSource = frag;
// Compile.
shader.compile();

destroy()

Destroy object.
setAttributes(params)

Sets attribute variables to shader program. Used in enchant.gl.Sprite3D contents and elsewhere.
```
var shader = new Shader(vert, frag);
shader.setAttributes({
    aVertexPosition: indices,
    aNormal: normals
});
```
Parameters:

{*} params

Level
setUniforms(params)

Set uniform variables to shader program. Used in enchant.gl.Sprite3D and elsewhere.
```
var shader = new Shader(vert, frag);
shader.setUniforms({
    uDiffuse: diffuse,
    uLightColor: lightColor
});
```
Parameters:

{*} params

Level
use()

Set shader program to be used.
