How would i smooth/damp rotation? [SOLVED]

So the effect i want to achieve is having a flashlights rotation lag behind my FPS camera, but i don't know how to do this. This is all the code i have right now. I'm so stumped...

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class FollowCam : MonoBehaviour
6. {
7.     public Transform target;
8.  
9.     public float smoothSpeed = 0.125f;
10.  
11.  
12.     void FixedUpdate()
13.     {
14.         transform.position = target.position;
15.        
16.        
17.     }
18. }
19.  

 

Simplest way to do a follow cam is this:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. public class FollowCam : MonoBehaviour
5. {
6.     public Transform target;
7.     public float cameraSpeed = 1f;
8.  
9.     void FixedUpdate()
10.     {
11.         transform.position = Vector3.MoveTowards(transform.position, target.position, cameraSpeed * Time.deltaTime);
12.     }
13. }

I'm assuming your target is using Rigidbody motion without interpolation.

however your question was about rotation, and I don't see any rotation code in what you shared. What have you tried so far?

 

Actually, what I'm trying to achieve is a normal spotlight attached to the camera, with position being fixed but rotation "lagging behind"; having to catch up to the camera's rotation. Should i add a rigid body to the spotlight?


Edit: Sorry for the nooby questions, started unity 2 weeks ago.

 

Oh ok. So I can help you properly can you answer some questions about your setup?

What kind of perspective does your game have? Is it first person? Is your camera attached to a player?

 

Yes, it it first person, with a simple character controller and a camera.

 

Ok so if you want the rotation to lag behind we have to make the flashlight a completely separate GameObject from the player (Not a child of the player at all). Then you can give it a script like this and point "target" at the camera:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. public class FollowCam : MonoBehaviour
5. {
6.     public Transform target;
7.     public float rotationSpeed = 30f; // degrees per second
8.     void LateUpdate()
9.     {
10.         // Lock position exactly.
11.         transform.position = target.position;
12.  
13.         // Play catchup with the rotation
14.        transform.rotation = Quaternion.RotateTowards(transform.rotation, target.rotation, rotationSpeed * Time.deltaTime);
15.     }
16. }

You might want to give the script a better name too. Just attach this to the flashlight and assign your player camera as "target" in the inspector.

 

WOW. Thank you SO much! It works perfectly! Still though, i have one question; it's fine if you don't want to answer. Could i apply some kind of curve/spline to make it ease out? Thanks in advance, i won't forget this!

Edit: Heard one way to do this is using SLERP.
