Hey everyone, I have created a small function library in Lua that will allow anyone with knowledge in Lua to make their game be online multiplayer.
It uses simple commands such as netsend(id,data,abtribute ) and netget(id).
The idea of the id is say if I made a game, the id could be "samsgame". Then, I could do netsend("samsgame","sam is at level 1","a"). If the abtribute is "a", it will add to the data, if it is "w", it will replace the data. Then another PSP would do something like
otherlevel = netget("samsgame")

Sending data takes .3 seconds, recieving data takes 1 to 3 seconds.

I do ask that if you use this, dont abuse it. Dont make programs that sit there and make hundreds of useless ID's just to spam. I also ask that if you are done with an id, delete it using netdelete(id). If an id does not exist, netsend will create it.

Also, please don't change the source if you include it in your programs. Please email/pm me with bugs and suggestions.

(I wonder when they will put this on the front page...emailed them yesterday)

BUGS:
-On release file, I put "r" adds to file, I meant "a".
-I need a new server because Yeldarbs domain's IP doesnt work... this will fix most freezes.

NEW: I have created a sample chat program.
Controls:
Square to refresh
Start to quit
Cross to enter message:
up/down to change letter
left is backspace, right is next letter
cross is send

Hey thanks, i know a couple devs that could use this, including myself

**youresam** · 02-23-2006, 05:00 PM

Wow.... I wonder why its not front-paged...

**Yeldarb** · 02-23-2006, 05:45 PM

It's a very worthy program, great job. I'm sure it will get on the front page soon =)

**cools** · 02-23-2006, 05:45 PM

Now this could come in handy! I may use it in Monopoly! I still need to dl and see its availabitlities and limitations though...

Its prob not front paged, because no mod ( that can post on front page ) has seen it.

**PSPHax0r9** · 02-23-2006, 05:47 PM

Just send them an email about it, and they'll probably post it. Seems really nice, and I will definitely use it once i start developing a new lua game that I'm not quite sure what it is yet...

**Yeldarb** · 02-23-2006, 05:48 PM

I know you sent an email before, but I sent another one in case they overlooked it :P

**KINGOFNOOBS** · 02-23-2006, 05:56 PM

hey yoursam, could i work with you later after i get the engine of my game down (naruto adventure) to maybe add some Co-op (ad-hoc, maybe online) and some Vs ( ad-hoc maybe online)?

**youresam** · 02-23-2006, 06:14 PM

Well, all this is is luaplayer code, I'm not sure what your program is in (download link expired), but I also dont think I will have time to work on this for a while (thats why I was rushing a release, finished in 2 hours).

Yup, thats right! report cards come tomorrow. cya everyone.

**Yeldarb** · 02-23-2006, 06:17 PM

I assume it's GPL so that others can improve upon it in your absence?

Um... the most I'll be out is 3 weeks, but I dont want anyone modifying it.

Not that they can, anyway. They would need access to the server.

But they could work on the client side Lua part :P

**alatnet** · 02-23-2006, 06:40 PM

Hey youresam, I modified the netlib code where it might have a faster data transfer speed and added 2 new functions:
netconnect()
and
netdisconnect()

I saw that your netlib code always connected to the server, did it's thing, then disconnected after it was done every time you called the function

. So, to smooth things out, I had the 2 functions created and modified the original code so that it always had a connection to the server when netconnect() was called untill the netdisconnect() was called :Punk:.

BTW, how many connections can the server hold?

Um.... no. The lua part is 'perfect', IE no way to improve it. ;)

Have you even tried your code?

If you keep the connection open, the next time you try to send a HTML GET command, the socket will close immediatly. Find a work-around to this and I will gladly put you in the credits.

**alatnet** · 02-23-2006, 06:45 PM

I added an if statement to every function:

Code:

if socket=nil or not socket:isConnected() then netconnect() end

That should be an ok work around.

No code is ever perfect or without room for improvement ;)

no it shouldnt.
It will FREEZE every time you try the 2nd time. this is because the socket is connected until you try to SEND the GET command. ou know, that bytesSend = whatever junk? yeah, that makes it lose connection to the socket.

Please take down your code, it does not work.

Yeah, well, I meant as far as connecting and getting data from the server. I'm going to add additional functions soon enough...

**alatnet** · 02-23-2006, 07:26 PM

Dang. Well back to the modding board.

**youresam** · 02-23-2006, 07:34 PM

Yup.

Now, in my other thread, framerate said:

Are you just writing a simple socket connection program? (I say "simple" like it's easy... was one of the trickiest things I've ever coded heh)

Now... if we (or Shine) could implement that (UDP), this thing would be fast. (Ever played Burnout online? LOTS of variables/second) I would imagine that PSPRadio uses UDP.

But, unfortuantuly, we have HTTP. Which, even though is awesome, is only good for webbrowsers and stuff like that.

**alatnet** · 02-23-2006, 07:55 PM

I couldn't really test out the program cus for some fracking reason my wan light goes on for a few seconds (around 2-5), light turns off, and nothing happens.

Ah! Bingo!
See, thats what was happening to my PSP about 2 days ago.
Do you by any chance use PSIX? I think that program might have messed it up. Or maybe WiFi sniffer. Please tell me witch of those programs you have (if any).

I fixed it by clicking "Restore Default Settings", then I had to re-set up my wireless network (20 digit WEP key!). But, after that it worked. Oh, and for some reason, my version number is still 2.00... (not the actual version, Ive never upgraded)

**Yeldarb** · 02-23-2006, 08:15 PM

Sam, do you mind if I try porting this to C tomorrow? I have a day off from school and that would be a pretty cool thing to do in it :P

Edit: by the way you made the main page at psp-hacks psphacks psp3d and dcemu

No I didn't use PSIX of Wifi sniffer, it does work for the infanstructure mode of the games that i have. I did up/downgrade a few times though. And i use LUA OS, File Assistant++, and UMD Emulator.

**Yeldarb** · 02-23-2006, 08:57 PM

Hey you made the front page

Congrats.

**Sturmeh** · 02-23-2006, 09:01 PM

This is interesting, but unsecure...

Its as easy as making a 2 line lua script, and a certain app would be destroyed...

Perhaps the ability to register an id, so it cannot be deleted?

**Fabre** · 02-23-2006, 10:28 PM

At first I was quite excited when I saw this, then I realised that it only uses infrastructure mode.

No offense to you, you have done a good job on this. But it would be really great if someone could make it this easy to communicate between two PSPs in AdHoc mode.

**mallchin** · 02-24-2006, 11:20 AM

I agree with Fabre. I am looking for some code to transfer arbitrary ascii/binary data in ad-hoc mode using LuaPlayer.
