Difficulties in Creating Multiplayer

Hello, I'm creating my first multiplayer game but I'm having a lot of difficulties, the most I could do was use the NetWorkManagerHUD to connect people, but when I tried to replace it I couldn't, so if you can help me understand how to do it multiplayer I would be grateful

 

Multiplayer can be a lot to take in, especially if you're trying to use Netcode which was just released as v1.0 with not enough external tutorials for this particular version. Right now it's best to follow the documentation and specifically exploring all the bite-size examples. Though they're a lot less complex than Boss Room it's still a lot of info to process which is normal.

Also be sure to install ParrelSync because this makes testing multiplayer a lot faster (no builds required you just run two or more Unity editors in parallel).
