Generic input event. Base class of all sort of input event. See [method Node._input]. $DOCS_URL/tutorials/inputs/inputevent.html $DOCS_URL/tutorials/2d/2d_transforms.html https://godotengine.org/asset-library/asset/515 https://godotengine.org/asset-library/asset/676 Returns [code]true[/code] if the given input event and this input event can be added together (only for events of type [InputEventMouseMotion]). The given input event's position, global position and speed will be copied. The resulting [code]relative[/code] is a sum of both events. Both events' modifiers have to be identical. Returns a [String] representation of the event. Returns [code]true[/code] if this input event's type is one that can be assigned to an input action. Returns [code]true[/code] if this input event is an echo event (only for events of type [InputEventKey]). Returns [code]true[/code] if this input event is pressed. Not relevant for events of type [InputEventMouseMotion] or [InputEventScreenDrag]. [b]Note:[/b] Due to keyboard ghosting, [method is_action_pressed] may return [code]false[/code] even if one of the action's keys is pressed. See [url=$DOCS_URL/tutorials/inputs/input_examples.html#keyboard-events]Input examples[/url] in the documentation for more information. 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. 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.
