|
|
1017 | * a maximum map size of 15x15. |

1019 | * the old function optimized to send as few face identifiers as possible, |
|
|
1020 | * at the expense of sending more coordinate location (coordinates were |

|
|
1022 | * we need 2 bytes for coordinates and 2 bytes for faces, such a trade off |
|
|
1023 | * maps no sense. Instead, we actually really only use 12 bits for coordinates, |
|
|
1024 | * and use the other 4 bits for other informatiion. For full documentation |
|
|
1025 | * of what we send, see the doc/Protocol file. |

|
|
1030 | * in the cells, there are faces and a count value. |

|
1031 | * we use the count value to hold the darkness value. If -1, then this space |
|

|
|
1027 | * a maximum map size of 15x15. |
|
|
1028 | * This function is much simpler than the old one. This is because |
|
|
1029 | * the old function optimized to send as few face identifiers as possible, |
|
|
1030 | * at the expense of sending more coordinate location (coordinates were |
|
|
1031 | * only 1 byte, faces 2 bytes, so this was a worthwhile savings). Since |
|
|
1032 | * we need 2 bytes for coordinates and 2 bytes for faces, such a trade off |
|
|
1033 | * maps no sense. Instead, we actually really only use 12 bits for coordinates, |
|
|
1034 | * and use the other 4 bits for other informatiion. For full documentation |
|
|
1035 | * of what we send, see the doc/Protocol file. |
|
|
1036 | * I will describe internally what we do: |
|
|
1037 | * the ns->lastmap shows how the map last looked when sent to the client. |
|
|
1038 | * in the lastmap structure, there is a cells array, which is set to the |
|
|
1039 | * maximum viewable size (As set in config.h). |
|
|
1040 | * in the cells, there are faces and a count value. |
|
|
1041 | * we use the count value to hold the darkness value. If -1, then this space |
|
|
1042 | * is not viewable. |
|
|
1043 | * we use faces[0] faces[1] faces[2] to hold what the three layers |
|
|
1044 | * look like. |
