Question

JavaScript => public static function SmoothDamp(current: Vector2, target: Vector2, ref currentVelocity: Vector2, smoothTime: float, maxSpeed: float = Mathf.Infinity, deltaTime: float = Time.deltaTime): Vector2;
C# => public static Vector2 SmoothDamp(Vector2 current, Vector2 target, ref Vector2 currentVelocity, float smoothTime, float maxSpeed = Mathf.Infinity, float deltaTime = Time.deltaTime);

Parameters 参数

current	The current position. 当前位置。
target	The position we are trying to reach. 我们尝试到达的位置 。
currentVelocity	The current velocity, this value is modified by the function every time you call it. 当前速度，该值每次通过函数修改。
smoothTime	Approximately the time it will take to reach the target. A smaller value will reach the target faster. 大约花费的时间达到目标。一个较小的值将达到目标速度更快。
maxSpeed	Optionally allows you to clamp the maximum speed. 选择允许的最大速度。
deltaTime	The time since the last call to this function. By default Time.deltaTime. 最后调用函数的时间。默认情况下Time.deltaTime。

Description 描述

Gradually changes a vector towards a desired goal over time.

随着时间的推移逐渐改变一个向量朝着期望的目标。

The vector is smoothed by some spring-damper like function, which will never overshoot.

这个弹簧阻尼函数是平滑的，不会过量。
