	<description>
		A Singleton that deals with inputs. This includes key presses, mouse buttons and movement, joypads, and input actions. Actions and their events can be set in the [b]Input Map[/b] tab in the [b]Project &gt; Project Settings[/b], or with the [InputMap] class.

			</return>
			<argument index="0" name="action" type="String">
			</argument>
			<argument index="1" name="strength" type="float" default="1.0">
			</argument>
			<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.
