@giorgi3: Thanks for the Links!

I had an idea:
The client controls his own character and also starts c_move. Then he saves the position of his character. He sends it to the server, which sends it to the other clients. Those correct the position of the character (for example Player3.x = Send_position[1];...).
But now I noticed, that the last part don't work. If the script should correct the position, I can't see a difference. Isn't it possible to change the position of an entity localy?

I hope you understand my idea and problem.
