Generic input event. Base class of all sort of input event. See [method Node._input]. https://docs.godotengine.org/en/latest/tutorials/inputs/inputevent.html https://docs.godotengine.org/en/latest/tutorials/2d/2d_transforms.html 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. Returns a [String] representation of the event. 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]. Returns [code]true[/code] if this input event matches a pre-defined action of any type. 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]. Returns [code]true[/code] if the given action is released (i.e. not pressed). Not relevant for events of type [InputEventMouseMotion] or [InputEventScreenDrag]. Returns [code]true[/code] if this input event's type is one that can be assigned to an input action. Returns [code]true[/code] if this input event is an echo event (only for events of type [InputEventKey]). Returns [code]true[/code] if this input event is pressed. Not relevant for events of type [InputEventMouseMotion] or [InputEventScreenDrag]. Returns [code]true[/code] if the given input event is checking for the same key ([InputEventKey]), button ([InputEventJoypadButton]) or action ([InputEventAction]). 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]. The event's device ID. [b]Note:[/b] This device ID will always be [code]-1[/code] for emulated mouse input from a touchscreen. This can be used to distinguish emulated mouse input from physical mouse input.
