Code Snippets

The namespace

using ChocDino.UIFX;

Add the BlurFilter component to your GameObject

// Add the component to your GameObject and set default properties
var blur = AddComponent<BlurFilter>();

blur.Algorithm = BlurAlgorithm.MultiBox;
blur.Downsample = Downsample.Auto;
blur.Blur = 4f;
blur.Strength = 1f;
blur.BlurAxes2D = BlurAxes2D.Default;
blur.ApplyAlphaCurve = false;
blur.AlphaCurve = new AnimationCurve(new Keyframe(0f, 1f, -1f, -1f), new Keyframe(1f, 0f, -1f, -1f));  // AlphaCurve is optional and can be null

Globally scale all BlurFilter Strength

BlurFilter.GlobalStrength = 0.5f;
