AnimationClip.SetCurve 设置曲线

# [AnimationClip](AnimationClip.html).SetCurve 设置曲线

function *SetCurve* (*relativePath* : string, *type* :
Type, *propertyName* : string, *curve* : [AnimationCurve](../AnimationCurve/AnimationCurve.html)) : void

### Parameters**参数**

* *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.
  应用给该曲线的游戏物体的路径。relativePath 被格式化类似路径，如"root/spine/leftArm"。如果 relativePath 为空，表示动画剪辑附加的游戏物体。
* *type*
  The class type of the component that is
  animated
  被动画的组件的类类型
* *propertyName*
  The name or path to the property being
  animated
  被动画的属性的名字或路径
* *curve*
  The animation curve //动画曲线

*Description* 描述

Assigns the curve to animate a specific property.

给动画指定曲线一个特殊的属性。

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

如果曲线为 null，曲线将被移除，如果曲线属性已经存在，曲线将被替换。

通常的名称是: "localPosition.x", "localPosition.y", "localPosition.z",
"localRotation.x", "localRotation.y", "localRotation.z", "localRotation.w"
"localScale.x", "localScale.y", "localScale.z".

For performance reasons [Transform](../Transform/Transform.html)
position, rotation and scale can only be animated as one property.

出于性能原因，Transform 的 position, rotation 和 scale 只能被动画作为一个属性。

using System.Collections;

public class example : MonoBehaviour {
	void Start() {
		AnimationCurve curve = AnimationCurve.Linear(0, 1, 2, 3);
		AnimationClip clip = new AnimationClip();
		clip.SetCurve("", typeof(Transform), "localPosition.x", curve);
		animation.AddClip(clip, "test");
		animation.Play("test");
	}
}
```

```
// Animates the x coordinate of a transform position
//动画transform位置的x轴坐标

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

// Create the clip with the curve
	//创建曲线的剪辑
	var clip : AnimationClip = new AnimationClip();
	clip.SetCurve("", Transform, "localPosition.x", curve);

// Add and play the clip
	//点击并播放剪辑
	animation.AddClip(clip, "test");
	animation.Play("test");
}

[Material](../Material/Material.html) 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:

[Material](../Material/Material.html) 材质属性可以动画，使用 shader 导出的属性名字。通常的名称是:
"_MainTex", "_BumpMap", "_Color", "_SpecColor", "_Emission".如何动画不懂财政属性类型：

```
Float属性： "PropertyName"  		
        Vector4 属性： "PropertyName.x", "PropertyName.y", "PropertyName.z", "PropertyName.w"
        Color 属性： "PropertyName.r", "PropertyName.g", "PropertyName.b", "PropertyName.a"
        UV 旋转属性："PropertyName.rotation"
        UV 偏移和缩放： "PropertyName.offset.x", "PropertyName.offset.y", "PropertyName.scale.x", "PropertyName.scale.y"
        对于在同一renderer的多个索引材质，你能想这样添加前缀："[1]._MainTex.offset.y"
```
