RecvNetMsg

RecvNetMsg()

Parameters:

None.

Description:

First off, this ONLY works when you have joined a network game via StartNetGame or JoinNetGame and you have created a player via CreateNetPlayer (you must create a player, even if it is just to lurk).

This returns a TRUE value if a message was received, FALSE if none has been received. This will typically go inside a function that is constantly being checked for message and decode and handle them. You will use NetMsgType, NetMsgFrom, NetMsgTo, and NetMsgData$ to get the important information from the message and act on it.

The example requires that you run it on a remote machine while the local computer runs the example in the SendNetMsg command.

Example:

; RecvNetMsg() example
; --------------------
; Run this program on the REMOTE computer to 'watch'
; the activity of the SendNetMsg example. Run that
; example on local machine.
;
; This program will tell you when a player involved in
; the game hits a wall ...

; We'll use this instead of JoinHostGame - make it easier
StartNetGame()

; Create a player - a player must be created to
; receive mesages!
playerID=CreateNetPlayer("Shane")

; Loop and get status
While Not KeyHit(1)

; Check to see if we've received a message
If RecvNetMsg() Then

; if we did, let's figure out what type it is
; we know it will be a user message, though
msgType=NetMsgType()

; 1-99 means a user message
If msgType>0 And msgType<100 Then

; Let's see who the message was from
msgFrom=NetMsgFrom()

; Let's get the message!
msgData$=NetMsgData$()

; Print the message
Print msgData$
End If
End If
Wend
