Vector2.SmoothDamp

Declaration

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

Parameters

current The current position.
target The position we are trying to reach.
currentVelocity The current velocity, this value is modified by the function every time you call it.
smoothTime Approximately the time it will take to reach the target. A smaller value will reach the target faster.
maxSpeed Optionally allows you to clamp the maximum speed.
deltaTime The 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.

// Smooth towards the target

using UnityEngine; using System.Collections;

public class ExampleClass : MonoBehaviour { public Transform target; public float smoothTime = 0.3F; private Vector2 velocity = Vector2.zero;

void Update() { // Define a target position above and behind the target transform Vector2 targetPosition = target.TransformPoint(new Vector2(0, 5));

// Smoothly move the camera towards that target position transform.position = Vector2.SmoothDamp(transform.position, targetPosition, ref velocity, smoothTime); } }
