	<methods>
		<method name="action_press">
			<return type="void" />
			<argument index="0" name="action" type="StringName" />
			<argument index="1" name="strength" type="float" default="1.0" />
			<description>
				This will simulate pressing the specified action.
				The strength can be used for non-boolean actions, it's ranged between 0 and 1 representing the intensity of the given action.
				[b]Note:[/b] This method will not cause any [method Node._input] calls. It is intended to be used with [method is_action_pressed] and [method is_action_just_pressed]. If you want to simulate [code]_input[/code], use [method parse_input_event] instead.
			</description>
		</method>
		<method name="action_release">
			<return type="void" />
			<argument index="0" name="action" type="StringName" />
			<description>
				If the specified action is already pressed, this will release it.
			</description>
		</method>
		<method name="add_joy_mapping">

			</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 in m/s² 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].

		<method name="get_action_raw_strength" qualifiers="const">
			<return type="float" />
			<argument index="0" name="action" type="StringName" />
			<argument index="1" name="exact_match" type="bool" default="false" />
			<description>
				Returns a value between 0 and 1 representing the raw intensity of the given action, ignoring the action's deadzone. In most cases, you should use [method get_action_strength] instead.
				If [code]exact_match[/code] is [code]false[/code], it ignores the input modifiers for [InputEventKey] and [InputEventMouseButton] events, and the direction for [InputEventJoypadMotion] events.
			</description>
		</method>
		<method name="get_action_strength" qualifiers="const">
			<return type="float" />
			<argument index="0" name="action" type="StringName" />
			<argument index="1" name="exact_match" type="bool" default="false" />
			<description>
				Returns a value between 0 and 1 representing the intensity of the given action. In a joypad, for example, the further away the axis (analog sticks or L2, R2 triggers) is from the dead zone, the closer the value will be to 1. If the action is mapped to a control that has no axis as the keyboard, the value returned will be 0 or 1.
				If [code]exact_match[/code] is [code]false[/code], it ignores the input modifiers for [InputEventKey] and [InputEventMouseButton] events, and the direction for [InputEventJoypadMotion] events.
			</description>

			<description>
				Returns [code]true[/code] when the user starts pressing the action event, meaning it's [code]true[/code] only on the frame that the user pressed down the button.
				This is useful for code that needs to run only once when an action is pressed, instead of every frame while it's pressed.
				If [code]exact_match[/code] is [code]false[/code], it ignores the input modifiers for [InputEventKey] and [InputEventMouseButton] events, and the direction for [InputEventJoypadMotion] events.
			</description>

		<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.
