Room Terrains

SMAUG sets room terrain by number, which is exactly what MSDP reports as well. Those number to terrain mappings are explained in | Herne's SMAUG Building Guide

1...Inside        (Weather doesn't show)
2...City
3...Field
4...Forest
5...Hills
6...Swimming      (Herne says "Water_swim: PC needs aqua_breath/fly/float or boat)
7...Water         (Herne says "Water_noswim: PC needs aqua_breath/fly/float or boat)
8...Underwater
9...Air
10..Desert
11..Unknown
12..OceanFloor    (PC needs aqua_breath. Can dig here)
13..Underground   (Can dig here)
14..Lava
15..Swamp

I'm not really sure on the difference between 6 and 7, they're both 'watery', both seem to have the same requirements.

If you're running tintin++ you can also just nab the function below and call it anytime you want to know the room terrain by doing something like:

#SHOWME @GetRoomTerrain{$msdp_info[ROOM_TERRAIN]}

Or:

#ALIAS {terrain} {#SHOWME @GetRoomTerrain{$msdp_info[ROOM_TERRAIN]}}

#FUNCTION {GetRoomTerrain} 
       {
       #VAR terrain {};
       #SWITCH {"$msdp_info[ROOM_TERRAIN]"} 
               {
               #CASE {"0"} {#var terrain Inside};
               #CASE {"1"} {#var terrain City};
               #CASE {"2"} {#var terrain Field};
               #CASE {"3"} {#var terrain Forest};
               #CASE {"4"} {#var terrain Hills};
               #CASE {"5"} {#var terrain Mountains};
               #CASE {"6"} {#var terrain Swimming};
               #CASE {"7"} {#var terrain Water};
               #CASE {"8"} {#var terrain Underwater};
               #CASE {"9"} {#var terrain Air};
               #CASE {"10"} {#var terrain Desert};
               #CASE {"11"} {#var terrain Unknown};
               #CASE {"12"} {#var terrain Seafloor};
               #CASE {"13"} {#var terrain Underground};
               #CASE {"14"} {#var terrain Lava};
               #CASE {"15"} {#var terrain Swamp};
               #DEFAULT {#var terrain NONE};
               };
       #RETURN {$terrain};
