Sprite rotating around a point at constant distance.

Hey all,
I'm trying to make a sprite rotate around another one (or a point) at a constant distance.
I tried to lookat the point then apply translate on the rotating object. But the movement is weird :



Here's my code :

Code (csharp):

1.  
2. Vector3 v3 = targetTransform.position - transform.position;
3. float angle = Mathf.Atan2(v3.y, v3.x) * Mathf.Rad2Deg;
4.  
5. //The translate :
6. transform.Translate (Vector3.up * movementSpeed * Time.deltaTime);
7.  
8. //The lookat :
9. qTo = Quaternion.AngleAxis (angle, Vector3.forward);
10. transform.rotation = qTo;
11.  
12.  

Where am I wrong ?

Thanks !

 

Is this the wrong forum ?

 

What about Transform.RotateAround? (Probably Scripting would have been a better category since this isn't specifically about the 2D features.)

Thank you Eric,
It was easy with rotateAround ... rtfm balou, rtfm.
