Vector3.Lerp 插值

# [Vector3](Vector3.html).Lerp 插值

static function *Lerp* (*from* : [Vector3](Vector3.html), *to* : [Vector3](Vector3.html), *t* : float) : [Vector3](Vector3.html)

*Description* 描述

Linearly interpolates between two vectors.

两个向量之间的线性插值。

Interpolates from towards to by amount t.

按照数字 t 在 from 到 to 之间插值。

t is clamped between [0...1]. When t = 0 returns from. When t = 1 returns to.
When t = 0.5 returns the average of from and to.

t 是夹在 [0...1]之间，当 t = 0 时，返回 from，当 t = 1 时，返回 to。当 t = 0.5 返回 from 和 to 的平均数。

```
using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	public Transform start;
	public Transform end;
	void Update() {
		transform.position = Vector3.Lerp(start.position, end.position, Time.time);
	}
}
```

```
// Animates the position to move from start to end within one second
//在1秒时间动画位置移动从from开始到to结束。
var start : Transform;
var end : Transform;
function Update () {
	transform.position = Vector3.Lerp(start.position, end.position, Time.time);
}
```

另一个例子：

```
using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
	public Transform target;
	public float smooth = 5.0F;
	void Update() {
		transform.position = Vector3.Lerp(transform.position, target.position, Time.deltaTime * smooth);
	}
}
```

```
// Follows the target position like with a spring
//像弹簧一个跟随目标物体
var target : Transform;
var smooth = 5.0;
function Update () {
	transform.position = Vector3.Lerp (
	transform.position, target.position,
	Time.deltaTime * smooth);
}
```
