public static Vector2 SmoothDamp(Vector2 current, Vector2 target, ref Vector2 currentVelocity, float smoothTime, float maxSpeed = Mathf.Infinity, float deltaTime = Time.deltaTime);

Parameters

currentThe current position.
targetThe position we are trying to reach.
currentVelocityThe current velocity, this value is modified by the function every time you call it.
smoothTimeApproximately the time it will take to reach the target. A smaller value will reach the target faster.
maxSpeedOptionally allows you to clamp the maximum speed.
deltaTimeThe time since the last call to this function. By default Time.deltaTime.

Description

Gradually changes a vector towards a desired goal over time.

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