Basic Question About Online Game Programming

| Greetings, Mortals. I have a rather basic question on programming online games. How do I Synchronize 2 Global Variables with each other? Example; The game has a global variable to keep track of the weather. When the game starts that variable should = 0, and then begin counting upward to determine the weather. At first the weather will be clear, but then will get snowy ect, as the variable counts upwards. When a second player joins the game, his Global Weather variable will = 0, since for him, the game just started. So then the first player might be in the middle of a snow storm while the second player has clear weather. How do I make the 2 Weather Variables match up?

| Client and server. The vars like that are in the server, and the players connect to the server.The clients contain individual player data, while the server contains data that is the same for all players. |

| Ok, thanks a lot Cp. Just one more question, The server would be the computer hosting the game right? The Worried WERDNA(The snow storm is getting worse) |

| Yes. The server is a program hosting the client programs, seperate from them. Of course, you could always build a host, so the person who makes the online game could host it, and have all the code in one game. :) |

| Ok, thanks for all of your help. It is now only a matter of time until Battle Gnomes 2008 is ready for download:) The Joyful WERDNA(The snow storm has cleared at last!) |

| One thing I do in my multiplayer attempt is when a client joins the game the server will send that client initialization information right from the get go. Things like player positions, object positions, enviromental information, etc. Then you just need to send the client information when things change on the server. |

| Ok, Thanks Xyle. I'll probably post some more questions pretty soon about online gaming, because I have no idea what I'm doing. The Clueless WERDNA(Lord Of ?) |

| Have you started any Network coding yet? I posted a basic udp chat system in the code archives, it uses the same port for both machines for sending and recieving, but I think it gives a good idea of how to set up the basic features needed to pass information in a client/ server setup. Heres the code archive post... http://www.blitzbasic.com/codearcs/codearcs.php?code=2261 |

| Thanks, this will be really useful. And yes, I have started some of my coding, but I'm sure that its pretty sloppy. If you don't mind I'll use your code as the starting block for my game, and just build from there. Again, thanks for your help, and thanks to you too Cp. Both of you have been incredibly helpful, and I don't know what I would have done without your assistance. The Grateful WERDNA(Lord Of Appreciation) |
