Roll-a-Ball Tutorial Camera still doing loop de loop as it follows the sphere.

Question

Hi everyone. I followed the exact steps for the Roll-a-Ball tutorial and I was able to affix my camera to the sphere but it is still doing a rotation (a vertical rotation around the z-axis) as I'm moving the sphere. I am using a prefab of a beach ball I downloaded from the assets store, could some setting in there be affecting it?

Hi @GSGregory! No, I didn't make it a child object. The camera is its own game object with a camera controller script attached. The following script is directly from Unity's tutorial on YouTube.

public class CameraController : MonoBehaviour { public GameObject player;

 private Vector3 offset;
 void Start()
 {
     offset = transform.position - player.transform.position;
 }

 // Update is called once per frame
 void Update()
 {
     
 }
 void LateUpdate()
 {
    transform.position = player.transform.position + offset;
     
 }

Hmm. I'm looking at the tutorial currently and trying to figure out what the issue is. In the meantime this is the script I currently use to manage my own camera.

 {
     public GameObject target;
     public Vector3 offset;
     public Transform targetTransform;
     public float offsetMax = 20f;
     public float offsetMin = 10f;
 
 
     // Update is called once per frame
     void LateUpdate()
     {
         transform.position = target.transform.position + offset;
         transform.LookAt(targetTransform);
 
         if (Input.mouseScrollDelta.y > 0 && offset.y < offsetMax)
         {
             offset.y += Input.mouseScrollDelta.y;
         }
 
         if (Input.mouseScrollDelta.y < 0 && offset.y > offsetMin)
         {
             offset.y += Input.mouseScrollDelta.y;
         }
     }
 }

Btw, what is the offset set to?

Can you link to the beachball you used?

Yes, of course! I got it from the Assets store.

Thank you so much for your help so far. I'm completely brand new to this!

I apologize if I answer thing in the wrong terms:

If by offset, do you mean the difference between the player's position and the camera's position...could I answer that by listing the vectors? I don't think I have offset set to anything... The position of my object is (-323, 70, -49), the camera is (-323, 89, -68) rotated at 45 degrees on the x-axis.

I also tried your script without messing with any values and it's still doing that weird rolling motion as I move the ball. So strange!
