Properties
  NameDescription
Public propertyAllowSimultaneousExecutionIfPlatformSpecificViewsAreDifferent
Allows simultaneous execution if the platform specific views do no match. Default is true.
(Inherited from GestureRecognizer.)
Public propertyClearTrackedTouchesOnEndOrFail
Whether tracked touches are cleared when the gesture ends or fails, default is false. By setting to true, you allow the gesture to possibly execute again with a different touch even if the original touch it failed on is still on-going. This is a special case, so be sure to watch for problems if you set this to true, as leaving it false ensures the most correct behavior, especially with lots of gestures at once.
(Inherited from GestureRecognizer.)
Public propertyCurrentTrackedTouches
The current tracked touches for the gesture
(Inherited from GestureRecognizer.)
Public propertyCustomData
Custom data for the gesture that you can attach, or just leave null if you don't need this This is useful if you want to retrieve this in a callback function, but it is not require for the gesture to work properly
(Inherited from GestureRecognizer.)
Public propertyDeltaX
Change in focus x in pixels
(Inherited from GestureRecognizer.)
Public propertyDeltaY
Change in focus y in pixels
(Inherited from GestureRecognizer.)
Public propertyDistanceX
The distance (in pixels) the gesture focus has moved from where it started along the x axis
(Inherited from GestureRecognizer.)
Public propertyDistanceY
The distance (in pixels) the gesture focus has moved from where it started along the y axis
(Inherited from GestureRecognizer.)
Public propertyEnabled
Whether the gesture is Enabled. Default is true.
(Inherited from GestureRecognizer.)
Public propertyFocusX
Focus x value in pixels (average of all touches)
(Inherited from GestureRecognizer.)
Public propertyFocusY
Focus y value in pixels (average of all touches)
(Inherited from GestureRecognizer.)
Public propertyIsRestarting
True if gesture is in process of restarting, false otherwise
(Inherited from GestureRecognizer.)
Public propertyMaximumNumberOfTouchesToTrack
The maximum number of touches to track. This gesture will never track more touches than this. Default is usually 1 or 2. Not all gestures will honor values higher than 1.
(Inherited from GestureRecognizer.)
Public propertyMinimumNumberOfTouchesToTrack
The minimum number of touches to track. This gesture will not start unless this many touches are tracked. Default is usually 1 or 2. Not all gestures will honor values higher than 1.
(Inherited from GestureRecognizer.)
Public propertyPlatformSpecificView
A platform specific view object that this gesture can execute in, null if none
(Inherited from GestureRecognizer.)
Public propertyPlatformSpecificViewScale
The platform specific view scale (default is 1.0). Change this if the view this gesture is attached to is being scaled.
(Inherited from GestureRecognizer.)
Public propertyPressure
Average pressure of all tracked touches
(Inherited from GestureRecognizer.)
Protected propertyPrevFocusX
Previous focus x
(Inherited from GestureRecognizer.)
Protected propertyPrevFocusY
Previous focus y
(Inherited from GestureRecognizer.)
Public propertyReceivedAdditionalTouches
Whether additional touches were added to the gesture since the last execute state.
(Inherited from GestureRecognizer.)
Public propertyRequireGestureRecognizersToFail
If this gesture reaches the EndPending state and the specified gestures fail, this gestures will end. If the specified gesture begins, executes or ends, then this gesture will immediately fail.
(Inherited from GestureRecognizer.)
Public propertyRequireGestureRecognizerToFail
Convenience method to add / remove one gesture to require failure on. Set to null to clear all require gestures to fail.
(Inherited from GestureRecognizer.)
Public propertyResetOnEnd
Whether the gesture should reset when it ends
(Inherited from GestureRecognizer.)
Public propertyScaleMultiplier
The current scale multiplier. Multiply your current scale value by this to scale.
Public propertyScaleMultiplierX
The current scale multiplier on x axis. Multiply your current x scale value by this to scale.
Public propertyScaleMultiplierY
The current scale multiplier on y axis. Multiply your current y scale value by this to scale.
Public propertySpeed
The speed of the gesture in pixels using focus
(Inherited from GestureRecognizer.)
Public propertyStartFocusX
Start focus x value in pixels (average of all touches)
(Inherited from GestureRecognizer.)
Public propertyStartFocusY
Start focus y value in pixels (average of all touches)
(Inherited from GestureRecognizer.)
Public propertyState
Get the current gesture recognizer state
(Inherited from GestureRecognizer.)
Public propertyThresholdUnits
The threshold in units that the touch must move to start the gesture. Default is 0.15.
Public propertyTrackedTouchCountIsWithinRange
Whether the current number of tracked touches is within the min and max number of touches to track
(Inherited from GestureRecognizer.)
Public propertyVelocityX
Velocity x in pixels using focus
(Inherited from GestureRecognizer.)
Public propertyVelocityY
Velocity y in pixels using focus
(Inherited from GestureRecognizer.)
Public propertyZoomSpeed
Additional multiplier for ScaleMultipliers. This will making scaling happen slower or faster. For this one finger scale gesture, this value is generally a small fraction, like 0.2 (the default). For a UI that starts 0,0 in the bottom left (like Unity), this value should be negative. For most other UI (0,0 in top left), this should be positive.

Methods
  NameDescription
Public methodAddRequiredGestureRecognizerToFail
Require a gesture to fail in order for this gesture to end
(Inherited from GestureRecognizer.)
Public methodAllowSimultaneousExecution
Allows the simultaneous execution with other gesture. This links both gestures so this method only needs to be called once on one of the gestures. Pass null to allow simultaneous execution with all gestures.
(Inherited from GestureRecognizer.)
Public methodAllowSimultaneousExecutionWithAllGestures
Allows simultaneous execution with all gestures
(Inherited from GestureRecognizer.)
Protected methodAreTrackedTouchesWithinDistance
Determines whether any tracked touches are within the distance of the starting point of each tracked touch.
(Inherited from GestureRecognizer.)
Public methodBeginGestureRestart
Allows the gesture to restart even if the touches are not lifted. This is only valid when called from the "Ended" state.
(Inherited from GestureRecognizer.)
Protected methodCalculateFocus(ICollectionGestureTouch)
Calculate the focus of the gesture
(Inherited from GestureRecognizer.)
Protected methodCalculateFocus(ICollectionGestureTouch, Boolean)
Calculate the focus of the gesture
(Inherited from GestureRecognizer.)
Public methodDisallowSimultaneousExecution
Disallows the simultaneous execution with other gesture. This unlinks both gestures so this method only needs to be called once on one of the gestures. By default, gesures are not allowed to execute simultaneously, so you only need to call this method if you previously allowed the gestures to execute simultaneously. Pass null to disallow simulatneous execution with all gestures (i.e. you previously called AllowSimultaneousExecution with a null value.
(Inherited from GestureRecognizer.)
Public methodDisallowSimultaneousExecutionWithAllGestures
Disallows simultaneous execution with all gestures
(Inherited from GestureRecognizer.)
Public methodDispose
Dispose of the gesture and ensure it is removed from the global list of active gestures
(Inherited from GestureRecognizer.)
Public methodDistance(Single)
Get the distance of a length, in units
(Inherited from GestureRecognizer.)
Public methodDistance(Single, Single)
Gets the distance of a vector, in units
(Inherited from GestureRecognizer.)
Public methodDistanceBetweenPoints
Gets the distance between two points, in units
(Inherited from GestureRecognizer.)
