You must've received the message already, determined by the <a href='RecvNetMsg().htm'>RecvNetMsg()</a> command - and probably determined the type of message with (<a href='NetMsgType().htm'>NetMsgType()</a>.<br>

The value returned from this command denotes the sender's ID number assigned to them when they were created with <a href='CreateNetPlayer.htm'>CreateNetPlayer</a> command. Use this to perform actions on the player on the local machine.<br>

You will use <a href='NetMsgType().htm'>NetMsgType()</a>, <a href='NetMsgTo().htm'>NetMsgTo()</a>, and <a href='NetMsgData$().htm'>NetMsgData$()</a> to get other important information from the message and act on it.<br>
