Detailed Description

Handles commands received by the server. This does not necessarily handle all commands - some might be in other files (like main.c)

This file handles commans from the server->client. See player.c for client->server commands.

this file contains most of the commands for the dispatch loop most of the functions are self-explanatory, the pixmap/bitmap commands receive the picture, and display it. The drawinfo command draws a string in the info window, the stats command updates the local copy of the stats and displays it. handle_query prompts the user for input. send_reply sends off the reply for the input. player command gets the player information. MapScroll scrolls the map on the client by some amount MapCmd displays the map either with layer packing or stack packing. packing/unpacking is best understood by looking at the server code (server/ericserver.c) stack packing is easy, for every map entry that changed, we pack 1 byte for the x/y location, 1 byte for the count, and 2 bytes per face in the stack. layer packing is harder, but I seem to remember more efficient: first we pack in a list of all map cells that changed and are now empty. The end of this list is a 255, which is bigger that 121, the maximum packed map location. For each changed location we also pack in a list of all the faces and X/Y coordinates by layer, where the layer is the depth in the map. This essentially takes slices through the map rather than stacks. Then for each layer, (max is MAXMAPCELLFACES, a bad name) we start packing the layer into the message. First we pack in a face, then for each place on the layer with the same face, we pack in the x/y location. We mark the last x/y location with the high bit on (11*11 = 121 < 128). We then continue on with the next face, which is why the code marks the faces as -1 if they are finished. Finally we mark the last face in the layer again with the high bit, clearly limiting the total number of faces to 32767, the code comments it's 16384, I'm not clear why, but the second bit may be used somewhere else as well. The unpacking routines basically perform the opposite operations.
