How to fade between 3 GUI textures?

If you're using GUITextures, you must have 3 of them (one for each texture) and control the individual guiTexture.color.a values - 0 is invisible, 1 is fully visible. You could define limits where the crossfade occurs, and create AnimationCurves to control each texture - like this:

var anxiety: float = 10; // your anxiety variable var gTex1: GUITexture; // drag the first texture here var gTex2: GUITexture; // drag the 2nd here var gTex3: GUITexture; // drag the 3rd here var lim12: float = 10; // 1st to 2nd limit var lim23: float = 20; // 2nd to 3rd limit var crossRange: float = 5; // crossfade range

public var alpha1: AnimationCurve; public var alpha2: AnimationCurve; public var alpha3: AnimationCurve;

function Start(){ var margin = crossRange/2; // find the necessary curve points: var v1 = lim12-margin; var v2 = lim12+margin; var v3 = lim23-margin; var v4 = lim23+margin; // create curves for each texture: alpha1 = AnimationCurve(Keyframe(0,1), Keyframe(v1,1), Keyframe(v2,0)); alpha2 = AnimationCurve(Keyframe(v1,0), Keyframe(v2,1), Keyframe(v3,1), Keyframe(v4,0)); alpha3 = AnimationCurve(Keyframe(0,0), Keyframe(v3,0), Keyframe(v4,1)); }

function Update(){ gTex1.color.a = alpha1.Evaluate(anxiety); gTex2.color.a = alpha2.Evaluate(anxiety); gTex3.color.a = alpha3.Evaluate(anxiety); }
