Vector3 Lerp差值计算

转载自：http://game.ceeger.com/Script/Vector3/Vector3.Lerp.html

static function Lerp (from : Vector3, to : Vector3, t : float) : Vector3

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。

• 0C#
• JavaScript

// 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：

• C#
• JavaScript

// Follows the target position like with a spring //像弹簧一样跟随目标物体
var target : Transform;
var smooth = 5.0;
function Update () {
	transform.position = Vector3.Lerp (
	transform.position, target.position,
	Time.deltaTime * smooth);
}
