<method name="accumulate">
<return type="bool">
</return>
<argument index="0" name="with_event" type="InputEvent">
</argument>
<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.

</method>
<method name="as_text" qualifiers="const">
<return type="String">
</return>
<description>
Returns a [String] representation of the event.

</return>
<argument index="0" name="action" type="String">
</argument>
<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].

<method name="is_action" qualifiers="const">
<return type="bool">
</return>
<argument index="0" name="action" type="String">
</argument>
<description>
Returns [code]true[/code] if this input event matches a pre-defined action of any type.

</return>
<argument index="0" name="action" type="String">
</argument>
<argument index="1" name="allow_echo" type="bool" default="false">
</argument>
<description>
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].
</description>
</method>
<method name="is_action_released" qualifiers="const">
<return type="bool">
</return>
<argument index="0" name="action" type="String">
</argument>
<description>
Returns [code]true[/code] if the given action is released (i.e. not pressed). Not relevant for events of type [InputEventMouseMotion] or [InputEventScreenDrag].
</description>
</method>

<description>
Returns [code]true[/code] if this input event's type is one that can be assigned to an input action.
</description>
</method>

<return type="bool">
</return>
<description>
Returns [code]true[/code] if this input event is an echo event (only for events of type [InputEventKey]).
</description>
</method>
<method name="is_pressed" qualifiers="const">
<return type="bool">
</return>
<description>
Returns [code]true[/code] if this input event is pressed. Not relevant for events of type [InputEventMouseMotion] or [InputEventScreenDrag].

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].
