Class CurveLookAtController

java.lang.Object
com.ardor3d.scenegraph.controller.interpolation.CurveLookAtController
All Implemented Interfaces:
SpatialController<Spatial>, Serializable
public class CurveLookAtController extends Object implements SpatialController<Spatial>, Serializable
CurveLookAtController class rotates a spatial to 'look at' a curve.

This class assumes the given delegate curve interpolation controller is already added to a spatial and is getting automatically updated as part of the main loop. Therefore this class doesn't call update on the delegate controller.
