Angle to Rotation

Questions & Answers

I’m trying to make the gun follow and look at the mouse in 2D. So I calculate the angle between the mouse position and front direction of the gun.

What is then the proper way to then rotate the gun based upon the angle?

EDIT: so that little stick needs to be aligned with the red ray.

This is why I cant use lookAt. The gun flips:

There’s really no reason to bring angles into this. You can transform the mouse position into world coordinates, then use Transform.LookAt() to orient the gun towards it.

I solved this by using Quaternion.FromToRotation. I will delete this question is it is messy and I did not describe the problem like I should have.
