LÖVE

Seems solved.. if you have too much time or don't know what to do a simple broadcast would be nice in LUBE just for the completeness of it.

New version, small change, added a check if a client exists, before attempting to send data (and failing).

EDIT: Moved the file back to the first post.

This has been most useful thanks, however I can't seem to get TCP to actually transmit anything.
Do I need to be doing more than just changing init to ("tcp")?

edit: It took longer than I liked but I found acceptall() was necessary in the server loop

I would've replied earlier if I knew those things and didn't have to look them up, well I'm glad you found it, and hope you will find some good use for LUBE.

So LUBE is ready for tcp and udp?

Just thinking about online game (not yet planning to actually write it), but I need tcp for it!

EDIT: Read through the LUBE.lua, and looks really sweet. It's a lot better to have all things in one file, than client.lua and server.lua. Makes things simpler. This doesn't need any additional .dll provided with the final game .exe? Or am I wrong?

Seems to be fairly simple to use all these. Have to try to do somekind of demo so I can see if it's really that simple

EDIT2: Forgot to ask; is this written for löve 0.6, or 0.5? Not sure if LUBE version number goes with the Löve version number.

It has tcp, it is lua only, so doesn't need an extra dll, and is written for 0.5.0, however, because I don't actually use love itself (IIRC) you should be able to run it on 0.6.0 without any problems.

Oh, I read that it has a bug or something that prevents the system to have more than one client per IP. What does this mean and is that information old? Does this mean that I can't have more than one client connecting to the server using LUBE?

You can, the clients can't have the same IP (yet), good thing you reminded me, I might look into it tomorrow.

Ah, so it handles all the data coming from one ip as a one client? Which means if you play with your friends in lan on a outside server, it handles all players as one client?

Yes, but it will handle the connect/disconnect messages the same way, so for an even number of clients the server acts as if there is nobody connected.
