Abstract base class for input events. Abstract base class of all types of input events. See [method Node._input]. $DOCS_URL/tutorials/inputs/inputevent.html $DOCS_URL/tutorials/2d/2d_transforms.html https://godotengine.org/asset-library/asset/515 https://godotengine.org/asset-library/asset/676 Returns [code]true[/code] if the given input event and this input event can be added together (only for events of type [InputEventMouseMotion]). The given input event's position, global position and speed will be copied. The resulting [code]relative[/code] is a sum of both events. Both events' modifiers have to be identical. Returns a [String] representation of the event. Returns a value between 0.0 and 1.0 depending on the given actions' state. Useful for getting the value of events of type [InputEventJoypadMotion]. If [param exact_match] is [code]false[/code], it ignores additional input modifiers for [InputEventKey] and [InputEventMouseButton] events, and the direction for [InputEventJoypadMotion] events. Returns [code]true[/code] if this input event matches a pre-defined action of any type. If [param exact_match] is [code]false[/code], it ignores additional input modifiers for [InputEventKey] and [InputEventMouseButton] events, and the direction for [InputEventJoypadMotion] events. Returns [code]true[/code] if the given action is being pressed (and is not an echo event for [InputEventKey] events, unless [param allow_echo] is [code]true[/code]). Not relevant for events of type [InputEventMouseMotion] or [InputEventScreenDrag]. If [param exact_match] is [code]false[/code], it ignores additional input modifiers for [InputEventKey] and [InputEventMouseButton] events, and the direction for [InputEventJoypadMotion] events. [b]Note:[/b] Due to keyboard ghosting, [method is_action_pressed] may return [code]false[/code] even if one of the action's keys is pressed. See [url=$DOCS_URL/tutorials/inputs/input_examples.html#keyboard-events]Input examples[/url] in the documentation for more information. Returns [code]true[/code] if the given action is released (i.e. not pressed). Not relevant for events of type [InputEventMouseMotion] or [InputEventScreenDrag]. If [param exact_match] is [code]false[/code], it ignores additional input modifiers for [InputEventKey] and [InputEventMouseButton] events, and the direction for [InputEventJoypadMotion] events. 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 has been canceled. Returns [code]true[/code] if this input event is an echo event (only for events of type [InputEventKey]). Any other event type returns [code]false[/code]. Returns [code]true[/code] if the specified [param event] matches this event. Only valid for action events i.e key ([InputEventKey]), button ([InputEventMouseButton] or [InputEventJoypadButton]), axis [InputEventJoypadMotion] or action ([InputEventAction]) events. If [param exact_match] is [code]false[/code], it ignores additional input modifiers for [InputEventKey] and [InputEventMouseButton] events, and the direction for [InputEventJoypadMotion] events. 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_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 this input event is released. Not relevant for events of type [InputEventMouseMotion] or [InputEventScreenDrag]. Returns a copy of the given input event which has been offset by [param local_ofs] and transformed by [param xform]. Relevant for events of type [InputEventMouseButton], [InputEventMouseMotion], [InputEventScreenTouch], [InputEventScreenDrag], [InputEventMagnifyGesture] and [InputEventPanGesture]. The event's device ID. [b]Note:[/b] [member device] can be negative for special use cases that don't refer to devices physically present on the system. See [constant DEVICE_ID_EMULATION]. Device ID used for emulated mouse input from a touchscreen, or for emulated touch input from a mouse. This can be used to distinguish emulated mouse input from physical mouse input, or emulated touch input from physical touch input.
