<description>
Stores information about mouse click events. See [method Node._input].
[b]Note:[/b] On Wear OS devices, rotary input is mapped to [constant MOUSE_BUTTON_WHEEL_UP] and [constant MOUSE_BUTTON_WHEEL_DOWN]. This can be changed to [constant MOUSE_BUTTON_WHEEL_LEFT] and [constant MOUSE_BUTTON_WHEEL_RIGHT] with the [member ProjectSettings.input_devices/pointing/android/rotary_input_scroll_axis] setting.
