I am making a simple 2d game and was trying to make a gun rotation script. The gun needs to flip when the cursor is on the left side of the screen.
This is the code I am using:
extends Sprite
var mouseposition
func _process(delta):
mouseposition = get_local_mouse_position()
set_flip_v(mouseposition.x <= 0)
The gun flips as it should but then I add this line:
rotation += mouseposition.angle()
After this the gun starts to rotate but the flip line doesn’t seem to work.
What am I doing wrong?

Problem is, that you rotate the object in it’s local coordinates → so the mouse local_mouse_position is not what you expect.
One solution is to compare mouse_global with object’s global:
mouseposition = get_global_mouse_position() - global_position;
rotation = mouseposition.angle();
set_flip_v(mouseposition.x <= 0);
The other (better) is to rotate the object within global’s space:
mouseposition = get_local_mouse_position()
set_flip_v(mouseposition.x <= 0)
global_rotation += mouseposition.angle()
Generaly it’s better to alter globals, not locals → because moving object in local will affect it’s collisions local_mouse and many more things.
thank you for your help
