Turret needs to aim at mouse cursor while maintaining constant limited speed

[waxen laurel]

I have tried 3 different methods and cannot think of any others, I will list the methods below and why they have not worked for me.

This is the most effective method I've found but it flips direction (and goes all the way around) when going from 360 to 0

if abs(difference) < SPEED * delta:
  rotation = rotation_angle
else:
  rotation += signf(difference) * SPEED * delta ```

lerp does not have a constant movement value, and just following the mouse does not have the delay or movement speed limit I am looking for.
Pls help :<

The dot product might help you determine whether to turn right or left.

In the example, they use it to determine in front or behind, but it works the same for left and right. Use the character's y basis vector instead of their x-vector.

Godot has a helper function, I think it's called angle_difference, which you should use instead of plain minus

Heres the updated functional code for anyone in the future with a similar issue
