			</description>
		</method>
		<method name="flush_buffered_events">
			<return type="void" />
			<description>
				Sends all input events which are in the current buffer to the game loop. These events may have been buffered as a result of accumulated input ([method set_use_accumulated_input]) or agile input flushing ([member ProjectSettings.input_devices/buffering/agile_event_flushing]).
				The engine will already do this itself at key execution points (at least once per frame). However, this can be useful in advanced cases where you want precise control over the timing of event handling.
			</description>
		</method>
		<method name="get_accelerometer" qualifiers="const">
			<return type="Vector3" />
			<description>
				Returns the acceleration of the device's accelerometer sensor, if the device has one. Otherwise, the method returns [constant Vector3.ZERO].
				Note this method returns an empty [Vector3] when running from the editor even when your device has an accelerometer. You must export your project to a supported device to read values from the accelerometer.
				[b]Note:[/b] This method only works on iOS, Android, and UWP. On other platforms, it always returns [constant Vector3.ZERO]. On Android the unit of measurement for each axis is m/s² while on iOS and UWP it's a multiple of the Earth's gravitational acceleration [code]g[/code] (~9.81 m/s²).

		<method name="is_key_pressed" qualifiers="const">
			<return type="bool" />
			<argument index="0" name="scancode" type="int" />
			<description>
				Returns [code]true[/code] if you are pressing the key in the current keyboard layout. You can pass a [enum KeyList] constant.
				[method is_key_pressed] is only recommended over [method is_physical_key_pressed] in non-game applications. This ensures that shortcut keys behave as expected depending on the user's keyboard layout, as keyboard shortcuts are generally dependent on the keyboard layout in non-game applications. If in doubt, use [method is_physical_key_pressed].
				[b]Note:[/b] Due to keyboard ghosting, [method is_key_pressed] may return [code]false[/code] even if one of the action's keys is pressed. See [url=$DOCS_URL/tutorials/inputs/input_examples.html#keyboard-events]Input examples[/url] in the documentation for more information.
			</description>
		</method>
		<method name="is_mouse_button_pressed" qualifiers="const">

			</description>
		</method>
		<method name="is_physical_key_pressed" qualifiers="const">
			<return type="bool" />
			<argument index="0" name="scancode" type="int" />
			<description>
				Returns [code]true[/code] if you are pressing the key in the physical location on the 101/102-key US QWERTY keyboard. You can pass a [enum KeyList] constant.
				[method is_physical_key_pressed] is recommended over [method is_key_pressed] for in-game actions, as it will make W/A/S/D layouts work regardless of the user's keyboard layout. [method is_physical_key_pressed] will also ensure that the top row number keys work on any keyboard layout. If in doubt, use [method is_physical_key_pressed].
				[b]Note:[/b] Due to keyboard ghosting, [method is_physical_key_pressed] may return [code]false[/code] even if one of the action's keys is pressed. See [url=$DOCS_URL/tutorials/inputs/input_examples.html#keyboard-events]Input examples[/url] in the documentation for more information.

				[codeblock]
				var a = InputEventAction.new()
				a.action = "ui_cancel"
				a.pressed = true
				Input.parse_input_event(a)
				[/codeblock]

			<argument index="2" name="hotspot" type="Vector2" default="Vector2( 0, 0 )" />
			<description>
				Sets a custom mouse cursor image, which is only visible inside the game window. The hotspot can also be specified. Passing [code]null[/code] to the image parameter resets to the system cursor. See [enum CursorShape] for the list of shapes.
				[code]image[/code]'s size must be lower than 256×256.
				[code]hotspot[/code] must be within [code]image[/code]'s size.
				[b]Note:[/b] [AnimatedTexture]s aren't supported as custom mouse cursors. If using an [AnimatedTexture], only the first frame will be displayed.
				[b]Note:[/b] Only images imported with the [b]Lossless[/b], [b]Lossy[/b] or [b]Uncompressed[/b] compression modes are supported. The [b]Video RAM[/b] compression mode can't be used for custom cursors.
			</description>
		</method>
		<method name="set_default_cursor_shape">
			<return type="void" />
			<argument index="0" name="shape" type="int" enum="Input.CursorShape" default="0" />
			<description>
				Sets the default cursor shape to be used in the viewport instead of [constant CURSOR_ARROW].
				[b]Note:[/b] If you want to change the default cursor shape for [Control]'s nodes, use [member Control.mouse_default_cursor_shape] instead.
				[b]Note:[/b] This method generates an [InputEventMouseMotion] to update cursor immediately.
			</description>
		</method>
		<method name="set_gravity">
			<return type="void" />
			<argument index="0" name="value" type="Vector3" />
			<description>
				Sets the gravity value of the accelerometer sensor. Can be used for debugging on devices without a hardware sensor, for example in an editor on a PC.
				[b]Note:[/b] This value can be immediately overwritten by the hardware sensor value on Android and iOS.
			</description>
		</method>
		<method name="set_gyroscope">
			<return type="void" />
			<argument index="0" name="value" type="Vector3" />
			<description>
				Sets the value of the rotation rate of the gyroscope sensor. Can be used for debugging on devices without a hardware sensor, for example in an editor on a PC.
				[b]Note:[/b] This value can be immediately overwritten by the hardware sensor value on Android and iOS.

		<method name="set_mouse_mode">

			<description>
				Sets the mouse mode. See the constants for more information.
			</description>
		</method>
		<method name="set_use_accumulated_input">
			<return type="void" />
			<argument index="0" name="enable" type="bool" />
			<description>
				Enables or disables the accumulation of similar input events sent by the operating system. When input accumulation is enabled, all input events generated during a frame will be merged and emitted when the frame is done rendering. Therefore, this limits the number of input method calls per second to the rendering FPS.
				Input accumulation is enabled by default. It can be disabled to get slightly more precise/reactive input at the cost of increased CPU usage. In applications where drawing freehand lines is required, input accumulation should generally be disabled while the user is drawing the line to get results that closely follow the actual input.

		<method name="start_joy_vibration">
			<return type="void" />
			<argument index="0" name="device" type="int" />
			<argument index="1" name="weak_magnitude" type="float" />
			<argument index="2" name="strong_magnitude" type="float" />
			<argument index="3" name="duration" type="float" default="0" />
			<description>
				Starts to vibrate the joypad. Joypads usually come with two rumble motors, a strong and a weak one. [code]weak_magnitude[/code] is the strength of the weak motor (between 0 and 1) and [code]strong_magnitude[/code] is the strength of the strong motor (between 0 and 1). [code]duration[/code] is the duration of the effect in seconds (a duration of 0 will try to play the vibration indefinitely).
				[b]Note:[/b] Not every hardware is compatible with long effect durations; it is recommended to restart an effect if it has to be played for more than a few seconds.
			</description>
		</method>
		<method name="stop_joy_vibration">
