Help with net code

-----------------------------------

Hi, I'm currently trying to program a sort of multi-player street fighter game for a school project.

The problem is that the game runs incredibly slow over the internet

attached is the game files

of course you cant help me, if the game compiled

here is the net code part of the player class


function sendData : string

currentPlayer:=""
currentPlayer:=currentPlayer + "x" + intstr(x)
currentPlayer:=currentPlayer + "y" + intstr(y)
currentPlayer:=currentPlayer + "p" + intstr(currentpic)

result currentPlayer
  
end sendData

procedure getData (newData : string)

x:=strint(newData(2..((index(newData, "y")-1))))
y:=strint(newData((index(newData, "y")+1)..((index(newData, "p")-1))))
currentpic:=strint(newData((index(newData, "p")+1)..(length(newData))))
  
end getData


if you try to play the game as is, it should work
but it is incredibly slow....

Can anyone help me with some sort of new net code
or is Turing not capable of something like this?

well the problem here is that you're exchanging information during each frame. So each frame a client needs to send out data, wait for other side to reply to data, read and interpret that.

You can try setting up some benchmark tests to see just how fast you can exchange information, but I'm gonna guess that it's a long stretch away from real-time.

Some games have an AI play for other parties in between data exchanges, and then syncs the states. Though I don't think that would be applicable for this type of a game.

you see the thing is,
I've tried making it check every 0.1/0.5/other interval seconds but it simply freezes everything whenever it is exchanging information

i've even tried to fork it so it does the stuff in the background
but all i got was some fatal errors

that being said, I dont think an AI inbetween exchanges would help much as the main problem is the pause that occurs when they try to exchange information

yeah, you might actually want to *gasp* use processes for data exchange. Better start reading on the topic.

i did try processes, but like i stated, i got some fatal/environmental errors that prevented me from further testing

however, it might've been because i tried to use the data before the data was actually exchanged due to the nature of processes

i'll try an if statement to prevent ^^ that.......hopefully there'll be some progress  :?

I can't check your source since I live in a police-state-dictatorship workplace, but make you're you're checking

Net.LineAvailable (etc.) to see if anything is available on the network before getting info.  That should resolve issues with demanding before the supply is there.
