Class PLocatableVector

java.lang.Object
  net.nexttext.PLocatableVector

All Implemented Interfaces:

Locatable

public class PLocatableVector
extends java.lang.Object
implements Locatable

The PLocatableVector encapsulates a PVector to use as a Locatable object.

The PVector class is part of the Processing core library so we are unable to have it implement the Locatable interface which is used by the behaviours. As a workaround, the PLocatableVector class is used, mainly internally to accept PVectors as argument.

Instead of extending from the PVector class, we store a PVector as variable. This allows to pass a PVector as argument to the constructor and store a pointer to it. This way modifying the PVector outside of the PLocatableVector object will change the value returned by the PLocatableVector object.

Constructor Summary

PLocatableVector()
Default constructor -- x, y and z gets assigned the value 0 by default.

PLocatableVector(float x, float y)
Constructs and initialize using xy properties ( z = 0 by default ).

PLocatableVector(float x, float y, float z)
Constructs and initialize using xyz properties.

PLocatableVector(processing.core.PVector vector)
Constructs and store pointer to the PVector.

Method Summary

processing.core.PVector

getLocation() A PLocatableVector implements the Locatable interface so that it can be used as a "location constant".
