core singleton class Input inherits Object (unsafe).

Official documentation

See the documentation of this class in the Godot engine’s official documentation. The method descriptions are generated from it and typically contain code samples in GDScript, not Rust.

Class hierarchy

Input inherits methods from:

Safety

All types in the Godot API have “interior mutability” in Rust parlance. To enforce that the official thread-safety guidelines are followed, the typestate pattern is used in the Ref and TRef smart pointers, and the Instance API. The typestate Access in these types tracks whether the access is unique, shared, or exclusive to the current thread. For more information, see the type-level documentation on Ref.

Implementations

Constants

Returns a reference to the singleton instance.

This will simulate pressing the specified action. The strength can be used for non-boolean actions, it’s ranged between 0 and 1 representing the intensity of the given action. Note: 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 _input, use [method parse_input_event] instead.

Default Arguments

  • strength - 1.0

If the specified action is already pressed, this will release it.

Adds a new mapping entry (in SDL2 format) to the mapping database. Optionally update already connected devices.

Default Arguments

  • update_existing - false

Returns the acceleration of the device’s accelerometer, if the device has one. Otherwise, the method returns [constant Vector3.ZERO]. 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. Note: This method only works on iOS, Android, and UWP. On other platforms, it always returns [constant Vector3.ZERO].

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.

Returns an [Array] containing the device IDs of all currently connected joypads.

Returns the currently assigned cursor shape (see [enum CursorShape]).

Returns the gravity of the device’s accelerometer, if the device has one. Otherwise, the method returns [constant Vector3.ZERO]. Note: This method only works on Android and iOS. On other platforms, it always returns [constant Vector3.ZERO].

Returns the rotation rate in rad/s around a device’s X, Y, and Z axes of the gyroscope, if the device has one. Otherwise, the method returns [constant Vector3.ZERO]. Note: This method only works on Android. On other platforms, it always returns [constant Vector3.ZERO].

Returns the current value of the joypad axis at given index (see [enum JoystickList]).

Returns the index of the provided axis name.

Receives a [enum JoystickList] axis and returns its equivalent name as a string.

Returns the index of the provided button name.

Receives a gamepad button from [enum JoystickList] and returns its equivalent name as a string.

Returns a SDL2-compatible device GUID on platforms that use gamepad remapping. Returns "Default Gamepad" otherwise.

Returns the name of the joypad at the specified device index.

Returns the duration of the current vibration effect in seconds.

Returns the strength of the joypad vibration: x is the strength of the weak motor, and y is the strength of the strong motor.

Returns the mouse speed for the last time the cursor was moved, and this until the next frame where the mouse moves. This means that even if the mouse is not moving, this function will still return the value of the last motion.

Returns the the magnetic field strength in micro-Tesla for all axes of the device’s magnetometer, if the device has one. Otherwise, the method returns [constant Vector3.ZERO]. Note: This method only works on Android and UWP. On other platforms, it always returns [constant Vector3.ZERO].

Returns mouse buttons as a bitmask. If multiple mouse buttons are pressed at the same time, the bits are added together.

Returns the mouse mode. See the constants for more information.

Returns true when the user starts pressing the action event, meaning it’s true only on the frame that the user pressed down the button. This is useful for code that needs to run only once when an action is pressed, instead of every frame while it’s pressed.

Returns true when the user stops pressing the action event, meaning it’s true only on the frame that the user released the button.

Returns true 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.

Returns true if you are pressing the joypad button (see [enum JoystickList]).

Returns true 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 true if you are pressing the key. You can pass a [enum KeyList] constant.

Returns true if you are pressing the mouse button specified with [enum ButtonList].

Notifies the Input singleton that a connection has changed, to update the state for the device 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.

Sample code is GDScript unless otherwise noted.

Feeds an InputEvent to the game. Can be used to artificially trigger input events from code. Also generates [method Node._input] calls. Example:

var a = InputEventAction.new()
a.action = "ui_cancel"
a.pressed = true
Input.parse_input_event(a)

Removes all mappings from the internal database that match the given GUID.

Sets a custom mouse cursor image, which is only visible inside the game window. The hotspot can also be specified. Passing null to the image parameter resets to the system cursor. See [enum CursorShape] for the list of shapes. image’s size must be lower than 256×256. hotspot must be within image’s size. Note: AnimatedTextures aren’t supported as custom mouse cursors. If using an AnimatedTexture, only the first frame will be displayed. Note: Only images imported with the Lossless, Lossy or Uncompressed compression modes are supported. The Video RAM compression mode can’t be used for custom cursors.

Default Arguments

  • shape - 0
  • hotspot - Vector2( 0, 0 )

Sets the default cursor shape to be used in the viewport instead of [constant CURSOR_ARROW]. Note: If you want to change the default cursor shape for Control’s nodes, use [member Control.mouse_default_cursor_shape] instead. Note: This method generates an InputEventMouseMotion to update cursor immediately.

Default Arguments

  • shape - 0

Sets the mouse mode. See the constants for more information.

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.

Starts to vibrate the joypad. Joypads usually come with two rumble motors, a strong and a weak one. weak_magnitude is the strength of the weak motor (between 0 and 1) and strong_magnitude is the strength of the strong motor (between 0 and 1). duration is the duration of the effect in seconds (a duration of 0 will try to play the vibration indefinitely). Note: 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.

Default Arguments

  • duration - 0

Stops the vibration of the joypad.

Vibrate Android and iOS devices. Note: It needs VIBRATE permission for Android at export settings. iOS does not support duration.

Default Arguments

  • duration_ms - 500

Sets the mouse position to the specified vector.

Methods from Deref<Target = Object>

Adds a user-defined signal. Arguments are optional, but can be added as an [Array] of dictionaries, each containing name: String and type: int (see [enum Variant.Type]) entries.

Default Arguments

  • arguments - [ ]

Sample code is GDScript unless otherwise noted.

Calls the method on the object and returns the result. This method supports a variable number of arguments, so parameters are passed as a comma separated list. Example:

call("set", "position", Vector2(42.0, 0.0))

Note: In C#, the method name must be specified as snake_case if it is defined by a built-in Godot node. This doesn’t apply to user-defined methods where you should use the same convention as in the C# source (typically PascalCase).

Safety

This function bypasses Rust’s static type checks (aliasing, thread boundaries, calls to free(), …).

Sample code is GDScript unless otherwise noted.

Calls the method on the object during idle time. This method supports a variable number of arguments, so parameters are passed as a comma separated list. Example:

call_deferred("set", "position", Vector2(42.0, 0.0))

Note: In C#, the method name must be specified as snake_case if it is defined by a built-in Godot node. This doesn’t apply to user-defined methods where you should use the same convention as in the C# source (typically PascalCase).

Safety

This function bypasses Rust’s static type checks (aliasing, thread boundaries, calls to free(), …).

Sample code is GDScript unless otherwise noted.

Calls the method on the object and returns the result. Contrarily to [method call], this method does not support a variable number of arguments but expects all parameters to be via a single [Array].

callv("set", [ "position", Vector2(42.0, 0.0) ])

Safety

This function bypasses Rust’s static type checks (aliasing, thread boundaries, calls to free(), …).

Returns true if the object can translate strings. See [method set_message_translation] and [method tr].

Sample code is GDScript unless otherwise noted.

Connects a signal to a method on a target object. Pass optional binds to the call as an [Array] of parameters. These parameters will be passed to the method after any parameter used in the call to [method emit_signal]. Use flags to set deferred or one-shot connections. See [enum ConnectFlags] constants. A signal can only be connected once to a method. It will throw an error if already connected, unless the signal was connected with [constant CONNECT_REFERENCE_COUNTED]. To avoid this, first, use [method is_connected] to check for existing connections. If the target is destroyed in the game’s lifecycle, the connection will be lost. Examples:

connect("pressed", self, "_on_Button_pressed") # BaseButton signal
connect("text_entered", self, "_on_LineEdit_text_entered") # LineEdit signal
connect("hit", self, "_on_Player_hit", [ weapon_type, damage ]) # User-defined signal

An example of the relationship between binds passed to [method connect] and parameters used when calling [method emit_signal]:

connect("hit", self, "_on_Player_hit", [ weapon_type, damage ]) # weapon_type and damage are passed last
emit_signal("hit", "Dark lord", 5) # "Dark lord" and 5 are passed first
func _on_Player_hit(hit_by, level, weapon_type, damage):
    print("Hit by %s (lvl %d) with weapon %s for %d damage" % [hit_by, level, weapon_type, damage])

Default Arguments

  • binds - [ ]
  • flags - 0

Disconnects a signal from a method on the given target. If you try to disconnect a connection that does not exist, the method will throw an error. Use [method is_connected] to ensure that the connection exists.

Sample code is GDScript unless otherwise noted.

Emits the given signal. The signal must exist, so it should be a built-in signal of this class or one of its parent classes, or a user-defined signal. This method supports a variable number of arguments, so parameters are passed as a comma separated list. Example:

emit_signal("hit", weapon_type, damage)
emit_signal("game_over")

Returns the Variant value of the given property. If the property doesn’t exist, this will return null. Note: In C#, the property name must be specified as snake_case if it is defined by a built-in Godot node. This doesn’t apply to user-defined properties where you should use the same convention as in the C# source (typically PascalCase).

Returns the object’s class as a String.

Returns an [Array] of dictionaries with information about signals that are connected to the object. Each Dictionary contains three String entries:

  • source is a reference to the signal emitter.
  • signal_name is the name of the connected signal.
  • method_name is the name of the method to which the signal is connected.

Gets the object’s property indexed by the given NodePath. The node path should be relative to the current object and can use the colon character (:) to access nested properties. Examples: "position:x" or "material:next_pass:blend_mode".

Returns the object’s unique instance ID. This ID can be saved in EncodedObjectAsID, and can be used to retrieve the object instance with [method @GDScript.instance_from_id].

Returns the object’s metadata entry for the given name.

Returns the object’s metadata as a [PoolStringArray].

Returns the object’s methods and their signatures as an [Array].

Returns the object’s property list as an [Array] of dictionaries. Each property’s Dictionary contain at least name: String and type: int (see [enum Variant.Type]) entries. Optionally, it can also include hint: int (see [enum PropertyHint]), hint_string: String, and usage: int (see [enum PropertyUsageFlags]).

Returns the object’s Script instance, or null if none is assigned.

Returns an [Array] of connections for the given signal.

Returns the list of signals as an [Array] of dictionaries.

Returns true if a metadata entry is found with the given name.

Returns true if the object contains the given method.

Returns true if the given signal exists.

Returns true if the given user-defined signal exists. Only signals added using [method add_user_signal] are taken into account.

Returns true if signal emission blocking is enabled.

Returns true if the object inherits from the given class.

Returns true if a connection exists for a given signal, target, and method.

Returns true if the [method Node.queue_free] method was called for the object.

Send a given notification to the object, which will also trigger a call to the [method _notification] method of all classes that the object inherits from. If reversed is true, [method _notification] is called first on the object’s own class, and then up to its successive parent classes. If reversed is false, [method _notification] is called first on the highest ancestor (Object itself), and then down to its successive inheriting classes.

Default Arguments

  • reversed - false

Notify the editor that the property list has changed, so that editor plugins can take the new values into account. Does nothing on export builds.

Removes a given entry from the object’s metadata. See also [method set_meta].

Assigns a new value to the given property. If the property does not exist, nothing will happen. Note: In C#, the property name must be specified as snake_case if it is defined by a built-in Godot node. This doesn’t apply to user-defined properties where you should use the same convention as in the C# source (typically PascalCase).

If set to true, signal emission is blocked.

Assigns a new value to the given property, after the current frame’s physics step. This is equivalent to calling [method set] via [method call_deferred], i.e. call_deferred("set", property, value). Note: In C#, the property name must be specified as snake_case if it is defined by a built-in Godot node. This doesn’t apply to user-defined properties where you should use the same convention as in the C# source (typically PascalCase).

Sample code is GDScript unless otherwise noted.

Assigns a new value to the property identified by the NodePath. The node path should be relative to the current object and can use the colon character (:) to access nested properties. Example:

set_indexed("position", Vector2(42, 0))
set_indexed("position:y", -10)
print(position) # (42, -10)

Defines whether the object can translate strings (with calls to [method tr]). Enabled by default.

Adds, changes or removes a given entry in the object’s metadata. Metadata are serialized and can take any Variant value. To remove a given entry from the object’s metadata, use [method remove_meta]. Metadata is also removed if its value is set to null. This means you can also use set_meta("name", null) to remove metadata for "name".

Assigns a script to the object. Each object can have a single script assigned to it, which are used to extend its functionality. If the object already had a script, the previous script instance will be freed and its variables and state will be lost. The new script’s [method _init] method will be called.

Returns a String representing the object. If not overridden, defaults to "[ClassName:RID]". Override the method [method _to_string] to customize the String representation.

Translates a message using translation catalogs configured in the Project Settings. Only works if message translation is enabled (which it is by default), otherwise it returns the message unchanged. See [method set_message_translation].
