	<methods>
		<method name="accumulate">
			<return type="bool" />
			<argument index="0" name="with_event" type="InputEvent" />
			<description>
				Returns [code]true[/code] if the given input event and this input event can be added together (only for events of type [InputEventMouseMotion]).
				The given input event's position, global position and speed will be copied. The resulting [code]relative[/code] is a sum of both events. Both events' modifiers have to be identical.
			</description>
		</method>
		<method name="as_text" qualifiers="const">
			<return type="String" />
			<description>
				Returns a [String] representation of the event.
			</description>
		</method>
		<method name="get_action_strength" qualifiers="const">
			<return type="float" />
			<argument index="0" name="action" type="String" />
			<argument index="1" name="exact_match" type="bool" default="false" />
			<description>
				Returns a value between 0.0 and 1.0 depending on the given actions' state. Useful for getting the value of events of type [InputEventJoypadMotion].
				If [code]exact_match[/code] is [code]false[/code], it ignores additional input modifiers for [InputEventKey] and [InputEventMouseButton] events, and the direction for [InputEventJoypadMotion] events.
			</description>
		</method>
		<method name="is_action" qualifiers="const">
			<return type="bool" />
			<argument index="0" name="action" type="String" />
			<argument index="1" name="exact_match" type="bool" default="false" />
			<description>
				Returns [code]true[/code] if this input event matches a pre-defined action of any type.
				If [code]exact_match[/code] is [code]false[/code], it ignores additional input modifiers for [InputEventKey] and [InputEventMouseButton] events, and the direction for [InputEventJoypadMotion] events.
			</description>
		</method>
		<method name="is_action_pressed" qualifiers="const">
			<return type="bool" />
			<argument index="0" name="action" type="String" />
			<argument index="1" name="allow_echo" type="bool" default="false" />
			<argument index="2" name="exact_match" type="bool" default="false" />
			<description>
				Returns [code]true[/code] if the given action is being pressed (and is not an echo event for [InputEventKey] events, unless [code]allow_echo[/code] is [code]true[/code]). Not relevant for events of type [InputEventMouseMotion] or [InputEventScreenDrag].
				If [code]exact_match[/code] is [code]false[/code], it ignores additional input modifiers for [InputEventKey] and [InputEventMouseButton] events, and the direction for [InputEventJoypadMotion] events.
				[b]Note:[/b] Due to keyboard ghosting, [method is_action_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.

		<method name="is_action_released" qualifiers="const">
			<return type="bool" />
			<argument index="0" name="action" type="String" />
			<argument index="1" name="exact_match" type="bool" default="false" />
			<description>
				Returns [code]true[/code] if the given action is released (i.e. not pressed). Not relevant for events of type [InputEventMouseMotion] or [InputEventScreenDrag].
				If [code]exact_match[/code] is [code]false[/code], it ignores additional input modifiers for [InputEventKey] and [InputEventMouseButton] events, and the direction for [InputEventJoypadMotion] events.
			</description>
		</method>
		<method name="is_action_type" qualifiers="const">
			<return type="bool" />
			<description>
				Returns [code]true[/code] if this input event's type is one that can be assigned to an input action.
			</description>
		</method>
		<method name="is_canceled" qualifiers="const">
			<return type="bool" />
			<description>
				Returns [code]true[/code] if this input event has been canceled.
			</description>
		</method>
		<method name="is_echo" qualifiers="const">
			<return type="bool" />
			<description>
				Returns [code]true[/code] if this input event is an echo event (only for events of type [InputEventKey]).
			</description>
		</method>
		<method name="is_pressed" qualifiers="const">
			<return type="bool" />
			<description>
				Returns [code]true[/code] if this input event is pressed. Not relevant for events of type [InputEventMouseMotion] or [InputEventScreenDrag].
				[b]Note:[/b] Due to keyboard ghosting, [method is_action_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_released" qualifiers="const">
			<return type="bool" />
			<description>
				Returns [code]true[/code] if this input event is released. Not relevant for events of type [InputEventMouseMotion] or [InputEventScreenDrag].
			</description>
		</method>
		<method name="shortcut_match" qualifiers="const">
			<return type="bool" />
			<argument index="0" name="event" type="InputEvent" />
			<argument index="1" name="exact_match" type="bool" default="true" />
			<description>
				Returns [code]true[/code] if the specified [code]event[/code] matches this event. Only valid for action events i.e key ([InputEventKey]), button ([InputEventMouseButton] or [InputEventJoypadButton]), axis [InputEventJoypadMotion] or action ([InputEventAction]) events.
				If [code]exact_match[/code] is [code]false[/code], it ignores additional input modifiers for [InputEventKey] and [InputEventMouseButton] events, and the direction for [InputEventJoypadMotion] events.

		</method>
		<method name="xformed_by" qualifiers="const">
			<return type="InputEvent" />
			<argument index="0" name="xform" type="Transform2D" />
			<argument index="1" name="local_ofs" type="Vector2" default="Vector2( 0, 0 )" />
			<description>
				Returns a copy of the given input event which has been offset by [code]local_ofs[/code] and transformed by [code]xform[/code]. Relevant for events of type [InputEventMouseButton], [InputEventMouseMotion], [InputEventScreenTouch], [InputEventScreenDrag], [InputEventMagnifyGesture] and [InputEventPanGesture].
