Hello everyone. Sorry I only read / write English. Awhile ago I found a site that had about 20 examples in Delphi [ compiled and with all source code]. They were from the red book, all in one zip file. They were as a game engine, walking through corridoors [ like FPS ], with lighting techniques , water , texturing and collision detection, all in various stages.I since formatted my pc and have lost the link. I have several good examples from this site, sulaco, nitrogen etc, however the site I seek has a very in deapth tutorials with many examples from red book in 1 zip. If this makes sense[ I hope it does] and you think you know the site to which I refer, can you please give me the link. That would be very much appreciated.Thank you.
