AnimationClip.SetCurve

Parameters

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.

**Note:** SetCurve will only work at runtime for Legacy AnimationClips. For Non-Legacy AnimationClips it is an editor-only function.

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

var anim: Animation;

function Start() {
	anim = GetComponent.<Animation>();

	// Animates the x coordinate of a transform position.
	// Create the curve.
	var curve : AnimationCurve = AnimationCurve.Linear(0, 1, 2, 3);

	// Create the clip with the curve.
	var clip : AnimationClip = new AnimationClip();
	clip.legacy = true;
	clip.SetCurve("", Transform, "localPosition.x", curve);
	
	// Add and play the clip
	anim.AddClip(clip, "test");
	anim.Play("test");
}
@script RequireComponent(Animation)

using UnityEngine;
using System.Collections;

[RequireComponent(typeof(Animation))]
public class ExampleClass : MonoBehaviour {
    public Animation anim;
    void Start() {
        anim = GetComponent<Animation>();
        AnimationCurve curve = AnimationCurve.Linear(0, 1, 2, 3);
        AnimationClip clip = new AnimationClip();
        clip.legacy = true;
        clip.SetCurve("", typeof(Transform), "localPosition.x", curve);
        anim.AddClip(clip, "test");
        anim.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"

var anim: Animation;

function Start() {
	anim = GetComponent.<Animation>();

	// Animate color's alpha and main texture's horizontal offset.
	var clip = new AnimationClip ();
	clip.legacy = true;
	clip.SetCurve ("", Material, "_Color.a",
	AnimationCurve (Keyframe(0, 0, 0, 0), Keyframe(1, 1, 0, 0)));
	clip.SetCurve ("", Material, "_MainTex.offset.x",
	AnimationCurve.Linear(0, 1, 2, 3));
	anim.AddClip (clip, clip.name);
	anim.Play(clip.name);
}
@script RequireComponent(Animation)

using UnityEngine;
using System.Collections;

[RequireComponent(typeof(Animation))]
public class ExampleClass : MonoBehaviour {
    public Animation anim;
    void Start() {
        anim = GetComponent<Animation>();
        AnimationClip clip = new AnimationClip();
        clip.legacy = true;
        clip.SetCurve("", typeof(Material), "_Color.a", new AnimationCurve(new Keyframe(0, 0, 0, 0), new Keyframe(1, 1, 0, 0)));
        clip.SetCurve("", typeof(Material), "_MainTex.offset.x", AnimationCurve.Linear(0, 1, 2, 3));
        anim.AddClip(clip, clip.name);
        anim.Play(clip.name);
    }
}

Property names can be looked up by setting Asset Serialization to Force Text mode in the Editor settings. The text files that are then written by the editor will include the names of the properties. For example, the yaml file written for a Scene object will include the Camera settings. Looking at this yaml file will show:
m_BackGroundColor: {r: .192156866, g: .301960796, b: .474509805, a: .0196078438}
m_NormalizedViewPortRect:
serializedVersion: 2
x: 0
y: 0
width: 1
height: 1
near clip plane: .300000012
far clip plane: 1000
field of view: 60
orthographic: 0
orthographic size: 5
m_Depth: -1
This shows that the name for the FOV parameter is "field of view". If you wanted to create an animation clip to animate the camera field of view, you would pass "field of view" as the propertyName.
