| 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. |
Gradually changes an angle given in degrees towards a desired goal angle over time.
The value is smoothed by some spring-damper like function. The function can be used to smooth any kind of value, positions, colors, scalars. The most common use is for smoothing a follow camera.
using UnityEngine;
public class Example : MonoBehaviour { //A simple smooth follow camera, // that follows the targets forward direction
Transform target; float smooth = 0.3f; float distance = 5.0f; float yVelocity = 0.0f;
void Update() { // Damp angle from current y-angle towards target y-angle float yAngle = Mathf.SmoothDampAngle(transform.eulerAngles.y, target.eulerAngles.y, ref yVelocity, smooth); // Position at the target Vector3 position = target.position; // Then offset by distance behind the new angle position += Quaternion.Euler(0, yAngle, 0) * new Vector3(0, 0, -distance); // Apply the position transform.position = position;
// Look at the target transform.LookAt(target); } }
