A singleton that deals with inputs. This includes key presses, mouse buttons and movement, joypads, and input actions. Actions and their events can be set in the [b]Input Map[/b] tab in the [b]Project > Project Settings[/b], or with the [InputMap] class.
[b]Note:[/b] This method will not cause any [method Node._input] calls. It is intended to be used with [method is_action_pressed] and [method is_action_just_pressed]. If you want to simulate [code]_input[/code], use [method parse_input_event] instead.
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 ([member 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.
Note this method returns an empty [Vector3] when running from the editor even when your device has an accelerometer. You must export your project to a supported device to read values from the accelerometer.
[b]Note:[/b] This method only works on iOS, Android, and UWP. On other platforms, it always returns [constant Vector3.ZERO]. On Android the unit of measurement for each axis is m/s² while on iOS and UWP it's a multiple of the Earth's gravitational acceleration [code]g[/code] (~9.81 m/s²).
Returns a value between 0 and 1 representing the raw intensity of the given action, ignoring the action's deadzone. In most cases, you should use [method get_action_strength] instead.
If [code]exact[/code] is [code]false[/code], it ignores additional input modifiers for [InputEventKey] and [InputEventMouseButton] events, and the direction for [InputEventJoypadMotion] events.
Returns a value between 0 and 1 representing the intensity of the given action. In a joypad, for example, the further away the axis (analog sticks or L2, R2 triggers) is from the dead zone, the closer the value will be to 1. If the action is mapped to a control that has no axis as the keyboard, the value returned will be 0 or 1.
If [code]exact[/code] is [code]false[/code], it ignores additional input modifiers for [InputEventKey] and [InputEventMouseButton] events, and the direction for [InputEventJoypadMotion] events.
[b]Note:[/b] This method only works on Android and iOS. On other platforms, it always returns [constant Vector3.ZERO]. On Android the unit of measurement for each axis is m/s² while on iOS it's a multiple of the Earth's gravitational acceleration [code]g[/code] (~9.81 m/s²).
Returns the rotation rate in rad/s around a device's X, Y, and Z axes of the gyroscope sensor, if the device has one. Otherwise, the method returns [constant Vector3.ZERO].
[b]Note:[/b] This method only works on Android and iOS. On other platforms, it always returns [constant Vector3.ZERO].
Returns the last mouse speed. To provide a precise and jitter-free speed, mouse speed is only calculated every 0.1s. Therefore, mouse speed will lag mouse movements.
Returns the magnetic field strength in micro-Tesla for all axes of the device's magnetometer sensor, if the device has one. Otherwise, the method returns [constant Vector3.ZERO].
Gets an input vector by specifying four actions for the positive and negative X and Y axes.
This method is useful when getting vector input, such as from a joystick, directional pad, arrows, or WASD. The vector has its length limited to 1 and has a circular deadzone, which is useful for using vector input as movement.
By default, the deadzone is automatically calculated from the average of the action deadzones. However, you can override the deadzone to be whatever you want (on the range of 0 to 1).
Returns [code]true[/code] when the user starts pressing the action event, meaning it's [code]true[/code] only on the frame that the user pressed down the button.
If [code]exact[/code] 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_just_pressed] may return [code]false[/code] even if one of the action's keys is pressed. See [url=$DOCS_URL/tutorials/inputs/input_examples.html#keyboard-events]Input examples[/url] in the documentation for more information.
Returns [code]true[/code] when the user stops pressing the action event, meaning it's [code]true[/code] only on the frame that the user released the button.
If [code]exact[/code] is [code]false[/code], it ignores additional input modifiers for [InputEventKey] and [InputEventMouseButton] events, and the direction for [InputEventJoypadMotion] events.
Returns [code]true[/code] if you are pressing the action event. Note that if an action has multiple buttons assigned and more than one of them is pressed, releasing one button will release the action, even if some other button assigned to this action is still pressed.
If [code]exact[/code] is [code]false[/code], it ignores additional input modifiers for [InputEventKey] and [InputEventMouseButton] events, and the direction for [InputEventJoypadMotion] events.
[b]Note:[/b] Due to keyboard ghosting, [method is_action_pressed] may return [code]false[/code] even if one of the action's keys is pressed. See [url=$DOCS_URL/tutorials/inputs/input_examples.html#keyboard-events]Input examples[/url] in the documentation for more information.
Returns [code]true[/code] if the system knows the specified device. This means that it sets all button and axis indices exactly as defined in [enum JoystickList]. Unknown joypads are not expected to match these constants, but you can still retrieve events from them.
Returns [code]true[/code] if you are pressing the key in the current keyboard layout. You can pass a [enum KeyList] constant.
[method is_key_pressed] is only recommended over [method is_physical_key_pressed] in non-game applications. This ensures that shortcut keys behave as expected depending on the user's keyboard layout, as keyboard shortcuts are generally dependent on the keyboard layout in non-game applications. If in doubt, use [method is_physical_key_pressed].
[b]Note:[/b] Due to keyboard ghosting, [method is_key_pressed] may return [code]false[/code] even if one of the action's keys is pressed. See [url=$DOCS_URL/tutorials/inputs/input_examples.html#keyboard-events]Input examples[/url] in the documentation for more information.
Returns [code]true[/code] if you are pressing the key in the physical location on the 101/102-key US QWERTY keyboard. You can pass a [enum KeyList] constant.
[method is_physical_key_pressed] is recommended over [method is_key_pressed] for in-game actions, as it will make W/A/S/D layouts work regardless of the user's keyboard layout. [method is_physical_key_pressed] will also ensure that the top row number keys work on any keyboard layout. If in doubt, use [method is_physical_key_pressed].
[b]Note:[/b] Due to keyboard ghosting, [method is_physical_key_pressed] may return [code]false[/code] even if one of the action's keys is pressed. See [url=$DOCS_URL/tutorials/inputs/input_examples.html#keyboard-events]Input examples[/url] in the documentation for more information.
Notifies the [Input] singleton that a connection has changed, to update the state for the [code]device[/code] index.
This is used internally and should not have to be called from user scripts. See [signal joy_connection_changed] for the signal emitted when this is triggered internally.
Sets the acceleration value of the accelerometer sensor. Can be used for debugging on devices without a hardware sensor, for example in an editor on a PC.
[b]Note:[/b] This value can be immediately overwritten by the hardware sensor value on Android and iOS.
Sets a custom mouse cursor image, which is only visible inside the game window. The hotspot can also be specified. Passing [code]null[/code] to the image parameter resets to the system cursor. See [enum CursorShape] for the list of shapes.
[b]Note:[/b] [AnimatedTexture]s aren't supported as custom mouse cursors. If using an [AnimatedTexture], only the first frame will be displayed.
[b]Note:[/b] Only images imported with the [b]Lossless[/b], [b]Lossy[/b] or [b]Uncompressed[/b] compression modes are supported. The [b]Video RAM[/b] compression mode can't be used for custom cursors.
[b]Note:[/b] On the web platform, the maximum allowed cursor image size is 128×128. Cursor images larger than 32×32 will also only be displayed if the mouse cursor image is entirely located within the page for [url=https://chromestatus.com/feature/5825971391299584]security reasons[/url].
Sets the gravity value of the accelerometer sensor. Can be used for debugging on devices without a hardware sensor, for example in an editor on a PC.
[b]Note:[/b] This value can be immediately overwritten by the hardware sensor value on Android and iOS.

Starts to vibrate the joypad. Joypads usually come with two rumble motors, a strong and a weak one. [code]weak_magnitude[/code] is the strength of the weak motor (between 0 and 1) and [code]strong_magnitude[/code] is the strength of the strong motor (between 0 and 1). [code]duration[/code] is the duration of the effect in seconds (a duration of 0 will try to play the vibration indefinitely). The vibration can be stopped early by calling [method stop_joy_vibration].
[b]Note:[/b] Not every hardware is compatible with long effect durations; it is recommended to restart an effect if it has to be played for more than a few seconds.
Vibrate the handheld device for the specified duration in milliseconds.
[b]Note:[/b] This method is implemented on Android, iOS, and HTML5. It has no effect on other platforms.
[b]Note:[/b] For Android, [method vibrate_handheld] requires enabling the [code]VIBRATE[/code] permission in the export preset. Otherwise, [method vibrate_handheld] will have no effect.
[b]Note:[/b] For iOS, specifying the duration is only supported in iOS 13 and later.
[b]Note:[/b] Some web browsers such as Safari and Firefox for Android do not support [method vibrate_handheld].
Sets the mouse position to the specified vector, provided in pixels and relative to an origin at the upper left corner of the game window.
Mouse position is clipped to the limits of the screen resolution, or to the limits of the game window if [enum MouseMode] is set to [constant MOUSE_MODE_CONFINED].
If [code]true[/code], similar input events sent by the operating system are accumulated. 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 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.
[b]Note:[/b] Input accumulation is [i]enabled[/i] by default. It is recommended to keep it enabled for games which don't require very reactive input, as this will decrease CPU usage.
Wait cursor. Indicates that the application is busy performing an operation. This cursor shape denotes that the application isn't usable during the operation (e.g. something is blocking its main thread).
Busy cursor. Indicates that the application is busy performing an operation. This cursor shape denotes that the application is still usable during the operation.
Window resize mouse cursor. The cursor is a double-headed arrow that goes from the bottom left to the top right. It tells the user they can resize the window or the panel both horizontally and vertically.
Window resize mouse cursor. The cursor is a double-headed arrow that goes from the top left to the bottom right, the opposite of [constant CURSOR_BDIAGSIZE]. It tells the user they can resize the window or the panel both horizontally and vertically.
