The possible tags in this example are:
Chapter 22: Multi-player games using sockets
QUERYBOXES – used to find out which boxes are currently under remote user control.
No parameters are passed. For each connection in the connection list the ID of the connection
is stored in the array ‘userids’. This array is initially set to eight zeros. If a connection is being
used then the array for this index is set to one. Then we build a string using the XML tag
QUERYBOXES and the value of each of the eight members of the ‘userid’ array is passed
to it. This message is then sent back to the socket that asked for it.
PICKBOX – used to tell the server which box this connection is controlling and the name
to use.
The name and ID are stripped out of the string that is passed. This information is then passed
on to each connection in the server’s connection list.
MOVEBOX – informs the server that the box has moved, which then passes the details onto each
connection.
The ID, XPOS and YPOS of the box are stripped from the passed message and passed on to
every connection.
DROPBOX – a user has stopped dragging the box. This information is passed to each connection.
The ID of the dropped box is stripped from the string and passed on to each connection in
the server’s connection list.
