I'm giving up any tries to continue this kind of projekt. I just can't find a way to make it work. Here, I have narrowed down the code to a bare bone. If you hit space, you send the info to the other PC. It's not more complicated than that, but I've tried both with two copies on the same PC and with two different PC:s om the same network and it is nigh impossible to recieve anything and I can't send if I'm a server. As a client sending is just fine.
If someone smarter can find the bug, I'll be happy.
