Field Detail

hitLayer

public final Layer hitLayer

The layer that was hit at the start of this interaction.

local

public final pythagoras.f.Point local

The current event's location, translated into the hit layer's coordinate space.

event

public E extends playn.core.Event.XY event

The event currently being dispatched in this interaction.

Constructor Detail

Interaction

public Interaction(Layer hitLayer,
                   boolean bubble)

Method Detail

x

public float x()

Returns event's x coordinate, for convenience.

Specified by:

x in interface pythagoras.f.XY

y

public float y()

Returns event's y coordinate, for convenience.

Specified by:

y in interface pythagoras.f.XY

captured

public boolean captured()

Returns whether this interaction is captured.

capture

public void capture()

Captures this interaction in ONLY mode. This causes subsequent events in this interaction to go only to the layer which is currently handling the interaction. Other layers in the interaction will receive a cancellation event and nothing further.

capture

public void capture(Interaction.CaptureMode mode)

Captures this interaction in the specified capture mode. Depending on the mode, subsequent events will go only to the current layer, or that layer and its parents, or that layer and its children. Other layers in the interaction will receive a cancellation event and nothing further.

cancel

public void cancel()

Cancels this interaction. All layers which normally participate in the action will be notified of the cancellation.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
