I suggest you write a 'tick' engine, which i.e. games like Planetarion use. This should be written in C or C++, compiled... You can run this using PHP of course, and run it from command line/shell, but PHP isnt ideal for this. If you have a decent server and not too much players (i.e. more than a hundred simultaneous players), then PHP will do. Any more than this, and I doubt PHP can handle without choking the server. You should also consider to study some math. I.e. if the plane is going to move at various speeds at various angles, basic math is needed. Good web games requires a lot of development time. Best regards Robert. -----Mensagem original----- De: Alexandre [mailto:mech39@xxxxxxxxxxxx] Enviada em: terça-feira, 22 de março de 2005 23:13 Para: php-general@xxxxxxxxxxxxx Assunto: Game development approach Hi there, I'm developing an online game (using PHP+MySQL, and being totally interfaced via web) which needs to have a "game cycle" running. For example, the player is flying a plane, so he sets the plane speed to 10%, then the game cycle needs to keep "moving the plane" forward (i.e. updating position), while the player doesn't order it a full stop. The point is how to implement this "game cycle"? I've done some research on the web and haven't found a feasible approach to this idea. Thanks in advance for any help.
