/**
 * This class handles warp effects, disappear and quickly turn up in a near
 * location. If geodata enabled and an object is between initial and final
 * point, flight is stopped just before colliding with object. Flight course and
 * radius are set as skill properties (flyCourse and flyRadius):
 * 
 * <li>Fly Radius means the distance between starting point and final point, it
 * must be an integer.</li> <li>Fly Course means the movement direction: imagine
 * a compass above player's head, making north player's heading. So if fly
 * course is 180, player will go backwards (good for blink, e.g.). By the way,
 * if flyCourse = 360 or 0, player will be moved in in front of him. <br>
 * <br>
 * 
 * If target is effector, put in XML self = "1". This will make _actor =
 * getEffector(). This, combined with target type, allows more complex actions
 * like flying target's backwards or player's backwards.<br>
