* This file implements all of the goo on the server side for handling |
36 |
|
|
* clients. It's got a bunch of global variables for keeping track of |
37 |
|
|
* each of the clients. |
38 |
|
|
* |
39 |
|
|
* Note: All functions that are used to process data from the client |
40 |
|
|
* have the prototype of (char *data, int datalen, int client_num). This |
41 |
|
|
* way, we can use one dispatch table. |
42 |
|
|
* |
43 |
|
|
* esrv_map_new starts updating the map |
44 |
|
|
* |
45 |
|
|
* esrv_map_setbelow allows filling in all of the faces for the map. |
46 |
|
|
* if a face has not already been sent to the client, it is sent now. |
47 |
|
|
* |
48 |
|
|
* mapcellchanged, compactlayer, compactstack, perform the map compressing |
49 |
|
|
* operations |
50 |
|
|
* |
51 |
|
|
* esrv_map_doneredraw finishes the map update, and ships across the |
52 |
|
|
* map updates. |
53 |
|
|
* |
54 |
|
|
* esrv_map_scroll tells the client to scroll the map, and does similarily |
55 |
|
|
* for the locally cached copy. |

1621 |
|
|

1623 |

1624 |
|
|
* at the expense of sending more coordinate location (coordinates were |
1625 |
|
|
* only 1 byte, faces 2 bytes, so this was a worthwhile savings). Since |
1626 |
|
|
* we need 2 bytes for coordinates and 2 bytes for faces, such a trade off |
1627 |
|
|
* maps no sense. Instead, we actually really only use 12 bits for coordinates, |
1628 |
|
|
* and use the other 4 bits for other informatiion. For full documentation |
1629 |
|
|
* of what we send, see the doc/Protocol file. |
1630 |
|
|
* I will describe internally what we do: |
1631 |
|
|
* the socket->lastmap shows how the map last looked when sent to the client. |
1632 |
|
|
* in the lastmap structure, there is a cells array, which is set to the |
1633 |
|
|
* maximum viewable size (As set in config.h). |
1634 |
|
|
* in the cells, there are faces and a count value. |
1635 |
|
|
* we use the count value to hold the darkness value. If -1, then this space |
1636 |
|
|
* is not viewable. |
1637 |
|
|
* we use faces[0] faces[1] faces[2] to hold what the three layers |
1638 |
|
|
