Hi I have been away from CF for a few years.
My latest activities have been learning Cocoa and Objective-C so I can program iPhone apps (mainly for friends and my own amazement). It's pretty cool to have all that power in your pocket! In an iPhone forum a question was asked: what/how to implement an Internet multiplayer option to an iPhone game he has already published. There are two basic needs: 1) Admin, Record keeping (user names, high scores), etc. 2) Interactive mulltiplayer play of the game CF/SQL seems a natural for 1 using a standard web server interface (HTTP/TCP). In this particular game (role playing) (HTTP/TCP) prolly would provide good enough performance to satisfy his needs. However, some of the more advanced iPhone games use fairly Hi-Res 2D and 3D graphics with fairly decent frame rates. The iPhone runs OS X (Unix), OpenGL ES and has a separate GPU. This type of game would require more frequent interaction and more data exchange. The HTTP/TCP connection and handshaking protocol, likely, has too much overhead to sustain frame rates on the client iPhones. Most games use the UDP protocol (connectionless, unordered, no packet delivery guarantee) with a specialized server app written in C++. .. I should mention here that all the heavy lifting is done on the iPhone clients-- the server only needs to send data such as the x/y/z coordinates of each player (plus some info on speed, weapon, direction). So, CF would not be serving the multiplayer graphic displays, rathet only the data needed by the iPhone clients to refresh their displays. If packets are lost, so what-- just a momentary lag until the next one comes along. Whew! Here are my questions: 1) Can the latest/greatest CF efficiently handle UDP through sockets or event gateways (or whatever) to make it a practical host of the multiplayer play? 2) Has anybody done this? 3) Any examples, code snippets? Any help will be greatly appreciated!
