Directplay and multiplayer messages

Hi for a fourth time
Is there any way to 'flush' server messages in directplay? When I send data quickly, I am getting the wrong response from the server.

I send messages in a while not recieve message loop. I tried removing the loop, but then the client doesn't recieve the response/ the server doesn't send one.

Thanks

Anyone?

Oh well

I am using BPLite now

What's BPLite?

I've noticed that when creating programs using BPlus that i get random data or not the correct response from certain events. It's very annoying that I have to program round blitz's own issues.

If I knew Blitz was to be abandoned I would never of purchased it. :(

Blitz --- abandoned? It still has an active forum base.

But to answer your question

BPLite is BlitzPlay Lite. It is a very powerful UDP alternative to DirectPlay. The built in commands are amazing, and my program, hopefully, will be completed within a month because of BlitzPlay's sample code and commands. I am looking to purchase the full version, but the director dude seems to have abandoned it (he hasn't gone on in 4 years).

I know it is a bit old but maybe helpful to someone. I just used Direct Play in a small game I made and I to needed to flush the messages to smooth out the game play. I did this by putting my RecvNetMsg routine in a repeat loop. Ending the loop with Until RecvNetMsg()=False to flush the server messages after each access. It work very nice and solved a lag issue I had with one computer that was behind a firewall which would get farther behind in this action game as the game went on because of a backlog of messages.

Something like this,

Repeat
If RecvNetMsg() Then  
msgType=NetMsgType()  
	If msgType>0 And msgType<100 Then
	msgFrom=NetMsgFrom()  
		If player=1 Then  
		msgData$=NetMsgData$() 
		If msgdata$="player1hit" Then p2score=p2score+1 : Goto reset
		player2x=stringtonumber(msgdata$,1)
		player2y=stringtonumber(msgdata$,2)
		player2frame=stringtonumber(msgdata$,3)
		bullet2x=stringtonumber(msgdata$,4)
		bullet2y=stringtonumber(msgdata$,5)
		ElseIf player=2 Then 
		msgData$=NetMsgData$() 
		If msgdata$="player2hit" Then p1score=p1score+1 : Goto reset
		player1x=stringtonumber(msgdata$,1)
		player1Y=stringtonumber(msgdata$,2)
		player1frame=stringtonumber(msgdata$,3)
		bullet1x=stringtonumber(msgdata$,4)
		bullet1y=stringtonumber(msgdata$,5)
		EndIf
	EndIf 
EndIf
Until RecvNetMsg()=False 

This way I read the messages until there is no message to read and keep the data in the last message.

One problem you may want to consider with Directplay is that it doesn't let you know what ports are in use, therefore if you need to forward any ports on your router for internet play it can be an issue.
