my code doesnt seem to work pls help me

how can i change that ?

iv got a other problem now with some code

func _unhandled_input(event):
	_mouse_input = event is InputEventMouseMotion and Input.get_mouse_mode()
Input.MOUSE_MODE_CAPTURED
	if _mouse_input:
		_rotation_input = event.relative.x
		_tilt_input = event.relative.y

This is the error i get :

Line 25:Unexpected "Identifier" in class body.
Line 26:Unexpected "Indent" in class body.
Line 27:Unexpected "Indent" in class body.
Line 28:Unexpected "Identifier" in class body.
Line 30:Expected end of file.

i was watching a video to make mouse movement , idk how to fix it xp

thank you but now i can just look down till the camera is fully rotated how do i fix that the camera has a up and down limmit ?

func _ready():
	original_scale = scale
	Input.set_mouse_mode(Input.MOUSE_MODE_CAPTURED)

func _input(event):
	if event is InputEventMouseMotion:
		rotate_y(deg_to_rad(-event.relative.x * mouse_sens))
		head.rotate_x(deg_to_rad(-event.relative.y * mouse_sens))

this is what i have

iv got a other problem i imprted a rooted model from mixamo and now my cammera movement is broken if i move my cursor the cammera does a barrel rol , and also my keybinds are broken
