What's different in Java? 1. The files There are new files: startnnc.class HGImage.class BoatCanvas.class BoatControl.class Sensor.class sinus_tab.class Radar.class Pilot.class KbdPilot.class nncFrame.class AutoPilot.class Net2Pilot.class Net1Pilot.class Boat.class NetPilot.java You will find the bitmaps in the directory 'images' and the INI-files in 'ini'. Each sea area can have an INI-file. See examples for details. 2. Function call for pilots In Java there is no call by reference, so I defined the function call only for incomming values. The output is defined as class member in the pilot class. Please notice the different names: the radar class carries the rays for scanning the map - not the sensor class. The sensor class represents only the colors in the map. You will find details in the Java source. So have fun, try the keyboard pilot, enjoy the autopilot and do your own pilot if you like. If you develop a pilot yourself, please send me an email with the code and I will add it to the classes. Axel Fischer december 1996 afischer@dbServ.de
