1052 |
|
|

1054 |
|

* the old function optimized to send as few face identifiers as possible, |
1055 |
|
|
* at the expense of sending more coordinate location (coordinates were |
1056 |
|
|
* only 1 byte, faces 2 bytes, so this was a worthwhile savings). Since |
1057 |
|
|
* we need 2 bytes for coordinates and 2 bytes for faces, such a trade off |
1058 |
|
|
* maps no sense. Instead, we actually really only use 12 bits for coordinates, |
1059 |
|
|
* and use the other 4 bits for other informatiion. For full documentation |
1060 |
|
|
* of what we send, see the doc/Protocol file. |
1061 |
|
|
* I will describe internally what we do: |
1062 |
|
|
* the ns->lastmap shows how the map last looked when sent to the client. |
1063 |
|
|
* in the lastmap structure, there is a cells array, which is set to the |
1064 |
|
|
* maximum viewable size (As set in config.h). |
1065 |
|
|
* in the cells, there are faces and a count value. |
1066 |
|
|
* we use the count value to hold the darkness value. If -1, then this space |
1067 |
|
|
* is not viewable. |
1068 |
|
|
* we use faces[0] faces[1] faces[2] to hold what the three layers |
1069 |
|
|
* look like. |
