RotateAround get just called once

I wanted to rotate the Camera around an object when the player touches and moves his finger on screen.

The problem is that it just rotate once.

I removed some code so its easy to replicate.

- if i click on screen and keep touching, the Debug gives me "pre" and "post", but just ONE rotation
- if i keep touching, it gives me still pre and post, but no rotation
- i tried transform.rotation *= Quaternion.Euler(0, rotation,0) , just to see if i can control the camera, which is the case, and it keeps rotating itself when holding the touch

The following script is on the camera

Code (CSharp):

1.  
2.  
3. if(Input.touchCount == 1)
4.         {
5.             Debug.Log("pre");
6.             transform.RotateAround(Vector3.zero, Vector3.up, 10f);
7.             transform.LookAt(Vector3.zero);
8.             Debug.Log("post");
9.         }
10.  

 

very important to note here that transform.LookAt sets the orientation, in other words, it overwrites the current rotation to a new one where the local z direction points at the given position

so.... your transform.RotateAround does nothing to the rotation itself, after all, you immediately overwrite its result

Edit:
just noticed that you do RotateAround and LookAt on the same point (Vector3.zero), so you probably dont mind that LookAt overwrites the orientation
is the problem that your object stops moving?

 

try this:

Code (CSharp):

1. if(Input.touchCount == 1)
2. {
3.    transform.RotateAround(Vector3.zero, Vector3.up, 1f);
4.    Vector3 relativePos = Vector3.zero - transform.position;
5.    Quaternion rotation = Quaternion.LookRotation(relativePos, Vector3.up);
6.    transform.rotation = rotation;
7. }

the LookAt apparently also overwrites your position change, this code works around that by doing the same as LookAt but calculating and writing the rotation separately, see:
https://docs.unity3d.com/ScriptReference/Quaternion.LookRotation.html

 

This works great
Thank you very much
