Detailed Description

Client handling.

Date:: 2003-12-02

This file implements all of the goo on the server side for handling clients. It's got a bunch of global variables for keeping track of each of the clients.

Note: All functions that are used to process data from the client have the prototype of (char *data, int datalen, int client_num). This way, we can use one dispatch table.

esrv_map_new starts updating the map

esrv_map_setbelow allows filling in all of the faces for the map. if a face has not already been sent to the client, it is sent now.

compactstack, perform the map compressing operations

esrv_map_scroll tells the client to scroll the map, and does similarily for the locally cached copy.

Todo:: smoothing should be automatic for latest clients. Remove some stuff we can assume is always on. fix comments for this file.

object 'ob' at 'ax,ay' on 'layer' is visible to the client.

This function does the following things: If is_head head is set, this means this is from the heads[] array, so don't try to store it away again - just send it and update our look faces.

1) If a multipart object and we are not at the lower right corner, store this info away for later use. 2) Check to see if this face has been sent to the client. If not, we add data to the socklist, update the last map, and send any other data the client will need (smoothing table, image data, etc) 3) Return 1 if function increased socket. 4) has_obj is increased by one if there are visible objects on this this space, whether or not we sent them. Basically, if has_obj is 0, we can clear info about this space. It could be set to 1 with the function returning zero - this means there are objects on the space we have already sent to the client.

A lot like the old AskSmooth (in fact, now called by AskSmooth).

Basically, it makes no sense to wait for the client to request a a piece of data from us that we know the client wants. So if we know the client wants it, might as well push it to the client.

object* heads[MAX_HEAD_POS][MAX_HEAD_POS][MAP_LAYERS] [static]

Using a global really isn't a good approach, but saves the over head of allocating and deallocating such a block of data each time run through, and saves the space of allocating this in the socket object when we only need it for this cycle.

If the serve is ever threaded, this needs to be re-examined.
