1246 | * This function uses the new map1 protocol command to send the map |
|

1247 | * to the client. It is necessary because the old map command supports |
|
|
1248 | * a maximum map size of 15x15. |
|
|
1249 | * This function is much simpler than the old one. This is because |
|
|
1250 | * the old function optimized to send as few face identifiers as possible, |
|
|
1251 | * at the expense of sending more coordinate location (coordinates were |
|
|
1252 | * only 1 byte, faces 2 bytes, so this was a worthwhile savings). Since |
|
|
1253 | * we need 2 bytes for coordinates and 2 bytes for faces, such a trade off |
|
|
1254 | * maps no sense. Instead, we actually really only use 12 bits for coordinates, |
|
|
1255 | * and use the other 4 bits for other informatiion. For full documentation |
|
|
1256 | * of what we send, see the doc/Protocol file. |
|
|
1257 | * I will describe internally what we do: |
|
|
1258 | * the ns->lastmap shows how the map last looked when sent to the client. |
|
|
1259 | * in the lastmap structure, there is a cells array, which is set to the |
|
|
1260 | * maximum viewable size (As set in config.h). |
|
|
1261 | * in the cells, there are faces and a count value. |
|
|
1262 | * we use the count value to hold the darkness value. If -1, then this space |
|
|
1263 | * is not viewable. |
|
|
1264 | * we use faces[0] faces[1] faces[2] to hold what the three layers |
|
|
1265 | * look like. |

896 | * maximum viewable size (As set in config.h). |

898 | * we use the count value to hold the darkness value. If -1, then this space |
|

899 | * is not viewable. |
