I''ve recompiled the code from the book and tried to link to the server with two different clients on different machines. The clients can see each other and both can move about, but collision detection and zones don''t seem to work. I can walk through objects freely. I looked at the code and it appears that the code in vUpdatePlayers() function contains code for the bounding box for the Arena from the previous Space Pirates game. Has somebody already reported this? Where can I get the code for the fix?
