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。
另一个例子:
// 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);
}
插值的使用很平凡,比如在网络坐标的传送中,每间隔一个fixupdate传送一次的坐标在使用过程中就需要使用到插值的方法达到平滑移动的效果。
