Vector3.Lerp 插值


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。

// 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);}

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);}
