I am trying to dip my toes into developing a multiplayer game. I made the rolling ball template work with multiple clients. Very simple.
I could then package up my game, and after disabling SteamVR, I could launch two copies of the game, to see if I could join from one to the other, while on the same computer. So in the two instances of the game, I use the following console commands respectively:
open SimpleMap?listener
open 127.0.0.1
This works. My client and host on the same computer can see each other and play together, just like in the editor.
So, next step would be to forward a port, and hope that a friend can connect using
open <my public IPv4 address>:port
However, according to online tools that check whether my ports are open, my port-forwarding didn’t work, even after I disabled my windows firewall. My ISP is called Ziggo and I’m using their ConnectBox router. Unfortunately all related discussion is in Dutch, which I don’t speak - but based on my google translate-fu, other people have had issues with port forwarding as well.
Note that me trying to connect to my own public IPv4 address also does not work - I’m not sure if it should.
So, in a desparate move, we all joined the same Hamachi session, and they tried connecting using
open <my Hamachi IpV4 address>
Which has also failed. And again, me trying to connect to my own Hamachi IPv4 address didn’t work either. I can still only connect via 127.0.0.1. Is that expected?
At this point I’m not sure what to try. Any suggestions would be greatly appreciated.
