Add a way to rotate the hands around the Z axis

[jamie-pate]

I would suggest shift+E/Q+mousewheel to rotate the hands around the Z axis?

I've added it to my project by inheriting your scene :D

extends "res://addons/xr-simulator/XRSimulator.gd"

func _input(event):
	var mb := event as InputEventMouseButton
	if mb && mb.button_index in [MOUSE_BUTTON_WHEEL_DOWN, MOUSE_BUTTON_WHEEL_UP] && mb.shift_pressed:
		var amount := 1.0 if mb.button_index == MOUSE_BUTTON_WHEEL_DOWN else -1.0
		amount = (scroll_sensitivity * amount)/20
		var done := false
		if Input.is_physical_key_pressed(KEY_Q) or toggle_left_controller:
			left_controller.rotate_z(amount)
			done = true
		if Input.is_physical_key_pressed(KEY_E) or toggle_right_controller:
			right_controller.rotate_z(amount)
			done = true
		if done:
			return
	super(event)
