GestureRecognizer Methods

Require a gesture to fail in order for this gesture to end

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.

Allows simultaneous execution with all gestures

Determines whether any tracked touches are within the distance of the starting point of each tracked touch.

Allows the gesture to restart even if the touches are not lifted. This is only valid when called from the "Ended" state.

Calculate the focus of the gesture

Calculate the focus of the gesture

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.

Disallows simultaneous execution with all gestures

Dispose of the gesture and ensure it is removed from the global list of active gestures

Get the distance of a length, in units

Gets the distance of a vector, in units

Gets the distance between two points, in units

Restart the gesture with a set of begin touches

Finalizer

Ignore a touch until it is released

The global total number of gestures in progress

Determines whether two points are within a specified distance

Call with the touches that began

Process cancelled touches

Call with the touches that ended

Call with the touches that moved

Remove a gesture needing to fail in order for this gesture to end

Reset all internal state for the gesture recognizer

Run an action on the main thread after a delay

Sets the state of the gesture. Continous gestures should set the executing state every time they change.

Simulate a gesture

Called when state changes

ToString

Call with the touches that began, child class should override

Call with the touches that ended, child class should override

Call with the touches that moved, child class should override

Track all touches in CurrentTrackedTouches start locations
