Description

"this code allows for not only a nice quaternion camera that will actually allow you to look up 90 degrees and down 90 degrees without gimbal lock, but you can even set it farther so you can actually move the mouse so you 'look between your legs' or 'bend backwards' - you can also use your menu settings to individually adjust your mouse sensitivity on X or Y if you want to. by default, it uses a common mouse sensitivity."

Main code

#in variables before functions
@export var camera : Node3D
var current_pitch:float = 0.0
var current_yaw:float = 0.0
@export var common_mouse_sensitivity:float = 0.09
var mouse_sens_x:float = common_mouse_sensitivity
var mouse_sens_y:float = common_mouse_sensitivity

func _input(event:InputEvent) -> void:
    if event is InputEventMouseMotion and Input.mouse_mode == Input.MOUSE_MODE_CAPTURED:
        var mouse_motion_event: InputEventMouseMotion = event as InputEventMouseMotion

        var yaw_delta: float = mouse_motion_event.relative.x * mouse_sens_x
        var pitch_delta: float = mouse_motion_event.relative.y * mouse_sens_y

        sway_mouse_input = Vector2(-yaw_delta,-pitch_delta)

        current_yaw_func(yaw_delta)
        current_pitch_func(pitch_delta)

func current_yaw_func(yaw_delta: float) -> void:
    current_yaw =  wrapf(current_yaw + yaw_delta, -360.0, 360.0)
    basis = Basis()
    rotate_object_local(Vector3.DOWN, deg_to_rad(current_yaw))
    orthonormalize()

func current_pitch_func(pitch_delta: float) -> void:
    current_pitch = wrapf(current_pitch + pitch_delta, -360.0, 360.0)
    current_pitch = clampf(current_pitch, -90.0, 90.0)
    camera.basis = Basis()
    camera.rotate_object_local(Vector3.LEFT, deg_to_rad(current_pitch))
    orthonormalize()
