AnimationClip.SetCurve

function SetCurve (relativePath : String, type : Type, propertyName : String, curve : AnimationCurve) : void

Parameters

Name	Description
relativePath	The path to the game object this curve applies to. relativePath is formatted similar to a pathname, e.g. "root/spine/leftArm". If relativePath is empty it refers to the game object the animation clip is attached to.
type	The class type of the component that is animated
propertyName	The name or path to the property being animated
curve	The animation curve

Description

Assigns the curve to animate a specific property.

If curve is null the curve will be removed. If a curve already exists for that property, it will be replaced.

Common names are: "localPosition.x", "localPosition.y", "localPosition.z", "localRotation.x", "localRotation.y", "localRotation.z", "localRotation.w" "localScale.x", "localScale.y", "localScale.z".

For performance reasons Transform position, rotation and scale can only be animated as one property.

JavaScripts

// Animates the x coordinate of a transform position

function Start () {
// Create the curve
var curve : AnimationCurve = AnimationCurve.Linear(0, 1, 2, 3);

// Create the clip with the curve
var clip : AnimationClip = new AnimationClip();
clip.SetCurve("", Transform, "localPosition.x", curve);

// Add and play the clip
animation.AddClip(clip, "test");
animation.Play("test");
}

class example(MonoBehaviour):

def Start():
curve as AnimationCurve = AnimationCurve.Linear(0, 1, 2, 3)
clip as AnimationClip = AnimationClip()
clip.SetCurve('', Transform, 'localPosition.x', curve)
animation.AddClip(clip, 'test')
animation.Play('test')

Material properties can be animated using the property name exported in the shader. Common property names are: "_MainTex", "_BumpMap", "_Color", "_SpecColor", "_Emission". How to animate different material property types:

Float properties: "PropertyName"
Vector4 properties: "PropertyName.x", "PropertyName.y", "PropertyName.z", "PropertyName.w"
Color properties "PropertyName.r", "PropertyName.g", "PropertyName.b", "PropertyName.a"
UV Rotation properties "PropertyName.rotation"
UV Offset and scale "PropertyName.offset.x", "PropertyName.offset.y", "PropertyName.scale.x", "PropertyName.scale.y"
To index into multiple materials on the same renderer you can prefix the attribute like this: "[1]._MainTex.offset.y"
