RB.EffectShader

Method - Static

public static void EffectShader(ShaderAsset shader)

Parameters

shader

ShaderAsset

Shader asset

Returns

Nothing.

Description

Set a custom post-processing effect shader which was previously created with ShaderAsset.Load. Using this method any post-processing effect can be created which takes the RetroBlit display as input, and any other inputs provided by RetroBlit shader methods.

Note that some RetroBlit built-in shaders will not work if a custom shader is specified, because they themselves are created by a built-in RetroBlit shader which will be replaced by a call to RB.EffectShader. To revert back to the built-in shader call RB.EffectReset.

See Assets/RetroBlit/Internal/Materials/PresentBasicShader.shader for an example of a minimal present shader, and Assets/RetroBlit/Resources/Demos/DemoReel/PresentRippleShader.shader for a simple ripple-effect shader.

Example

ShaderAsset shaderEffect = new ShaderAsset();

void Initialize() {
    shaderEffect.Load("shaders/ripple");
    RB.EffectShader(shaderEffect);
}

void Render() {
    // Animate a value in the post processing shader to create a moving ripple effect
    shaderEffect.FloatSet("wave", RB.Ticks / 25.0f);
}
