input¶

(module)

Module for accessing input devices such as touches, keyboard, mouse and gamepads

Touches¶

class touch¶

Represents a single touch over time. Generated in response to touch events by the device in response to user interactions

id: number: An id that can be used to uniquely identify the touch

state: enum

The current state of the touch, can be:

BEGAN - the touch began this frame
MOVING - the touch moved this frame
ENDED - the touch ended this frame
CANCELLED - the touch was cancelled (usually by another view or gesture recognizer)

type: enum

The type of touch, can be:

touch.direct - a touch resulting from direct contact with the screen
touch.indirect - a touch that does not result from direct contact with the screen
touch.pencil - a touch resulting from the pencil
touch.pointer - a touch resulting from a button based device

x: number: The x position of the touch (in screen coordinates)

y: number: The y position of the touch (in screen coordinates)

prevX: number: The previous x position of the touch (in screen coordinates)

prevY: number: The previous y position of the touch (in screen coordinates)

deltaX: number: The x position delta of the touch (in screen coordinates)

deltaY: number: The y position delta of the touch (in screen coordinates)

pos: vec2: The position of the touch (in screen coordinates) as a vector

prevPos: vec2: The previous position of the touch (in screen coordinates) as a vector

delta: number: The position delta of the touch (in screen coordinates) as a vector

force: number: The amount of force being applied (only applies to pencil type touches)

maxForce: number: The maximum amount of force that can be applied (only applies to pencil type touches)

timestamp: number: The time when this touch event occured (only applies to pencil type touches)

azimuth: number: The azimuth angle of the pencil (only applies to pencil type touches)

altitude: number: The altitude angle of the pencil

radiusTolerance: number: The amount the estimated radius can vary due to hardware tolerances

radius: number: The estimated radius of the touch

precisePos: vec2: The precise location of the touch (if available)

precisePrevPos: vec2: The previous precise location of the touch (if available)

Gestures¶

class gesture¶

Represents a single gesture event

state: enum¶: The current state of the gesture

location: vec2¶: The location of the gesture event on the screen

translation: vec2¶: The translation of the gesture event relative to its starting location

delta: vec2¶: The delta of the gesture event since last update

pinchScale: number¶: The scale of a pinch gesture relative to its starting distance

pinchDelta: number¶: The delta of the pinch distance since last update

pinchVelocity: number¶: The current change in pinch distance over time

rotationAngle: number¶: The current angle of a rotation gesture relative to its’ starting angle

rotationVelocity: number¶: The current change in rotation angle over time

touchCount: integer¶: The current number of touches associated with this gesture

class gesture.tap¶

Tap gesture recognizer (using system gesture recognizer for implementation)

static gesture.tap(callback[, minTouches = 1, maxTouches = 1])¶: Creates and registers a new tap gesture recognizer that will call callback(gesture) when recognized

enabled: boolean¶: Enables/disables this gesture recognizer

class gesture.pan¶

Pan gesture recognizer (using system gesture recognizer for implementation)

static gesture.pan(callback[, minTouches = 1, maxTouches = 1])¶: Creates and registers a new pan gesture recognizer that will call callback(gesture) when recognized

enabled: boolean¶: Enables/disables this gesture recognizer

class gesture.pinch¶

Pinch gesture recognizer (using system gesture recognizer for implementation)

static gesture.pinch(callback)¶: Creates and registers a new pinch gesture recognizer that will call callback(gesture) when recognized

enabled: boolean¶: Enables/disables this gesture recognizer

class gesture.rotation¶

Rotation gesture recognizer (using system gesture recognizer for implementation)

static gesture.rotation(callback)¶: Creates and registers a new rotation gesture recognizer that will call callback(gesture) when recognized

enabled: boolean¶: Enables/disables this gesture recognizer

Keyboard¶

key.pressing(keyCode)¶

Queries whether the key is currently being pressed this frame

Parameters:: keyCode (constant) – The keyCode to query
Returns:: Is the key being pressed this frame
Return type:: boolean

key.wasPressed(keyCode)¶

Queries whether the key is was pressed down this frame

Parameters:: keyCode (constant) – The keyCode to query
Returns:: Was the key pressed down this frame
Return type:: boolean

key.wasReleased(keyCode)¶

Queries whether the supplied key code was released this frame

Parameters:: keyCode (constant) – The keyCode to query
Returns:: Was the key released this frame
Return type:: boolean

key.modifiers()¶

Queries the current key modifiers as a bit field, which is composed of the following bit mask constants:

key.leftAlt
key.rightAlt
key.alt
key.leftCtrl
key.rightCtrl
key.ctrl
key.leftCmd
key.rightCmd
key.cmd

Parameters:: keyCode (constant) – The keyCode to query
Returns:: Was the key released this frame
Return type:: boolean
