Two points:

1. The scripting for an online game is about an exta 1500 lines of code. You really should read about the scripting first. You can't just put your game online and let people play together. I would recommend Locoweed's tutorial. It is very helpful. If that doesn't work, PM me and I will help explain more.

2. You need to set up a static IP. People need to have your game on their computer, or have it running through a website app. You know where you input your commands for nexus and screensize and stuff? That is where you input your command: -ip xx.xxx.xx.xx (whatever your IP is).

Need any more help, PM or email me (mttcttrll@snet.net).
