Sprite rotating around a point at constant distance.

Unity Engine

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 :

Vector3 v3 = targetTransform.position - transform.position;
float angle = Mathf.Atan2(v3.y, v3.x) * Mathf.Rad2Deg;

//The translate :
transform.Translate (Vector3.up * movementSpeed * Time.deltaTime);

//The lookat :
qTo = Quaternion.AngleAxis (angle, Vector3.forward);
transform.rotation = qTo;

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.
