<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>
|
|
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.

<description>
|
|
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.

<param 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 [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.

<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 [param exact_match] is [code]false[/code], it ignores additional input modifiers for [InputEventKey] and [InputEventMouseButton] events, and the direction for [InputEventJoypadMotion] events.

<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.
|

</method>
|
|
<method name="is_canceled" qualifiers="const">
|
|
<return type="bool" />
|
|
<description>
|
|
Returns [code]true[/code] if this input event has been canceled.
|

</method>
|
|
<method name="is_echo" qualifiers="const" keywords="is_repeat">
|
|
<return type="bool" />
|
|
<description>
|
|
Returns [code]true[/code] if this input event is an echo event (only for events of type [InputEventKey]). An echo event is a repeated key event sent when the user is holding down the key. Any other event type returns [code]false[/code].
|
|
[b]Note:[/b] The rate at which echo events are sent is typically around 20 events per second (after holding down the key for roughly half a second). However, the key repeat delay/speed can be changed by the user or disabled entirely in the operating system settings. To ensure your project works correctly on all configurations, do not assume the user has a specific key repeat configuration in your project's behavior.

<param index="0" name="event" type="InputEvent" />
|
|
<param index="1" name="exact_match" type="bool" default="true" />
|
|
<description>
|
|
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.
|
|
[b]Note:[/b] Only considers the event configuration (such as the keyboard key or joypad axis), not state information like [method is_pressed], [method is_released], [method is_echo], or [method is_canceled].

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.
