i've been trying to make a multiplayer game, but i don't quite understand...

if(global.host)
{
clearbuffer()                  /*making sure nothing else is being sent to the other IP*/
writestring("Host Data")   /*just marking data*/
writeint(x)                     /*sending coordinates*/
writeint(y)
writeshort(round(angle))  /*coordinate to mouse angle(eyes)*/
bufferencrypt("blahh");    /*encrypting*/
sendmessage(<OtherIP>);/*finally sending data to the other comp..*/

bufferdecrypt("blahh")     /*recieving*/
S=readstring()               /*pointlessness*/
X=readint()                   /*recieving the other IP's coordinates*/
Y=readint()
Angle=readshort()          /*and angle*/
}else
{
clearbuffer()                 /*other IP  (2 player game anyways)*/
writestring("Other Data")
writeint(x)
writeint(y)
writeshort(round(angle))
bufferencrypt("blahh");
sendmessage(<HostIP>);

bufferdecrypt("blahh")
S=readstring()
X=readint()
Y=readint()
Angle=readshort()
}

it seems that it sends (X,Y,Angle) it to the same computer...
and i am using 2 different comps

also

draw_sprite(sprite_index,0,x,y)
draw_sprite_ext(sprite_index,1,x,y,1,1,angle,c_white,1)
draw_sprite(sprite_index,0,X,Y)
draw_sprite_ext(sprite_index,1,X,Y,1,1,Angle,c_white,1)

this supposeably gonna draw my other player...
i dont know what i did wrong..


and im using hamachi...

help would be appreciated

I'm working on multiplayer as well, so I'll be glad to help if I can. What exactly is the problem, though? From what I can see, it seems like you're forgetting to call receivemessage() before trying to decrypt with bufferdecrypt(). You need to receive the message first before you can decrypt or read it.

Also, right after you call receivemessage(), make sure a message actually was received before trying to read it. Simply do something like "size = receivemessage();" and "if size <= 0 exit;", because if the size of the message is 0 or less, you of course won't be able to read it.
