I have a problem…

I have a 2D game with guns and stuff (pokemon 2D style not top down) and i have the problem that my body dont turns in the direction my gun is shooting at.

For the Player I have a normal Kinematic body and For the bullets I have an area that turns with mouse_position ( look_at(get_global_mouse_position)) )
And my Player only have animations for north, east, south and west…

Is it possible to shoot in the direction my character is looking at ( east, west, south or nord) ?

If it’s the case, you can measure the angle between player and mouse to determine which way they are facing. Then set the animation accordingly

func _process(delta):
	var angle_to_mouse = global_position.angle_to_point(get_global_mouse_position())
	angle_to_mouse = rad2deg(angle_to_mouse)
	angle_to_mouse = wrapf(angle_to_mouse, 0, 360)

	if angle_to_mouse < 45 or angle_to_mouse >= 315:
		animation = "left"
	elif angle_to_mouse >= 45 and angle_to_mouse < 135:
		animation = "up"
	elif angle_to_mouse >= 135 and angle_to_mouse < 225:
		animation = "right"
		animation = "down"

Then for the bullet, you can check which direction the character is facing, and set the direction vector to the bullet on instancing it.

func shoot():
	var bullet = bullet_scene.instance()
	bullet.global_position = global_position
	match animation:
			bullet.dir = Vector2.LEFT
			bullet.dir = Vector2.RIGHT
			bullet.dir = Vector2.DOWN
			bullet.dir = Vector2.UP

And here’s the bullet script

extends Sprite

var dir: Vector2

func _physics_process(delta):
	position += dir * 10
