<description>
Sends all input events which are in the current buffer to the game loop. These events may have been buffered as a result of accumulated input ([method set_use_accumulated_input]) or agile input flushing ([member ProjectSettings.input_devices/buffering/agile_event_flushing]).

The engine will already do this itself at key execution points (at least once per frame). However, this can be useful in advanced cases where you want precise control over the timing of event handling.

<description>
Enables or disables the accumulation of similar input events sent by the operating system. When input accumulation is enabled, all input events generated during a frame will be merged and emitted when the frame is done rendering. Therefore, this limits the number of input method calls per second to the rendering FPS.
Input accumulation is enabled by default. It can be disabled to get slightly more precise/reactive input at the cost of increased CPU usage. In applications where drawing freehand lines is required, input accumulation should generally be disabled while the user is drawing the line to get results that closely follow the actual input.

Contains mouse and pen motion information. Supports relative, absolute positions and velocity. See [method Node._input].
[b]Note:[/b] By default, this event is only emitted once per frame rendered at most. If you need more precise input reporting, call [method Input.set_use_accumulated_input] with [code]false[/code] to make events emitted as often as possible. If you use InputEventMouseMotion to draw lines, consider implementing [url=https://en.wikipedia.org/wiki/Bresenham%27s_line_algorithm]Bresenham's line algorithm[/url] as well to avoid visible gaps in lines if the user is moving the mouse quickly.
