LÖVE

Hello everyone,

I've been trying to to send data via udp to a friend, but he dosen't receive anything. I don't know if it is because of the ip address (his looks like 192.168.*.*, is that the address where i should send the data to ?) or the port (he set his to 87**). Could someone show me an example of a working server and a working client ? It would be very nice !

192.168.*.* is a private (local) IP Address - are you on the same local network as your friend? It won't work otherwise.

There's a tutorial and source code on the Wiki:
https://love2d.org/wiki/Tutorial:Networking_with_UDP
https://love2d.org/wiki/Tutorial:Networ ... -TheServer
https://love2d.org/wiki/Tutorial:Networ ... -TheClient

Do note that those tutorials aren't the best, since, for one, you can indeed create the server itself with löve, and you don't need to mess around with building lua with sockets, and second, using (lua-)enet may be better than using luasocket, and both do come with löve built-in.

Also, to get your actual internet-facing public IP adress, use a website like whatismyip.com

Does my friend need to open his ports on his internet box so I can communicate with him without being on the same network ?

Depends, whoever is running the server needs to have open ports.

His computer ports ?

You or your friend must have white IP (accessible from global network) or external server (routable too) that connect users. Google NAT and ports and OSI-model.
