Server script always have to be running
Then u can run multiple client scripts from wherever the network that you want
The server has to be running on the IPV4 address in the script on that machine
You can also run multiple client on that same machine too (default 2)
E.g. for testing
Gameover score (default 10)
Paddle velocity (default 5)
For now, if both players want to restart need to restart server and client again.
Can setup multiple client using a gameId
Can use a single class to differentiate between players
Can make a single player with CPU AI
