Even more angle problems.

Hi guys.

So I used Quaternion.Angle here to get the angle between 2 vectors also by including rotation, so now my problem is that when the player moves around the other object the angle changes. Is there a way to get get an angle just from the player rotation and the other object rotation, without including the position of the 2 vectors. Hope you understand.

So here is my script so far:

 targetAngle = Quaternion.Angle(transform.rotation,playerTarget.transform.rotation);
 if(engaged==true && targetAngle >= 120)
 {
 //The rest of the shooting script. Not needed here.
 }

I used 120 here becouse I used debug.log and it seemed good... untill i started moving around. Any clues?

Wait, the rotation of playerTarget doesn't change and neither does your object's rotation? In that case, targetAngle must be the same. If it changes, one of the rotations/quaternions most definitely changes. The game objects' relative positions do not change the outcome of Quaternion.Angle, as it takes the angle of two quaternions, which solely describe a rotation in Unity, as opposed to getting the angle between vectors.
