Light Switch
I have a script that sets a global when a player pushes a button. The room script I've been working on checks the global and was going to change the rooms from darkened to lit in which it is assigned. Is there not a way to do that? I haven't had any luck in finding any variable/commands to do anything like it. I could hack around it, like changing the exits to teleport to lit versions of the rooms or casting infravision on them, but it seems... kludgy.

Well, you were right. No easy way to do it, without kludging.

so I made a small patch for your dg_variables.c file, allowing you to write: 
%room.toggleflag(DARK)%


         } else
           snprintf(str, slen, "0");
       }
+      else if (!str_cmp(field, "toggleflag")) {
+        if (subfield && *subfield) {
+          room_rnum thisroom = real_room(r->number);
+          int i, item=-1;
+          for (i=0; i<NUM_ROOM_FLAGS && item < 0; i++)
+            if (!strcmp(subfield, room_bits[i]))
+              item = i;
+
+          // disallow some internal flags.
+          if (item < 0 || item == ROOM_DEATH || item == ROOM_GODROOM || 
+              item == ROOM_HOUSE || item == ROOM_HOUSE_CRASH || item == ROOM_ATRIUM ||
+              item == ROOM_OLC || item == ROOM_BFS_MARK || item == ROOM_WORLDMAP) {
+            strcpy(str, "");
+            script_log("Trigger: %s, VNum %d, type: %d. room.toggleflag unknown or bad flag: %s",
+                       GET_TRIG_NAME(trig), GET_TRIG_VNUM(trig), type, subfield);
+          } else {
+            TOGGLE_BIT_AR(ROOM_FLAGS(thisroom), item);
+            if (IS_SET_AR(ROOM_FLAGS(thisroom), item))
+              snprintf(str, slen, "1");
+            else
+              snprintf(str, slen, "0");
+          }
+        }
+        else {
+          strcpy(str, "");
+          script_log("Trigger: %s, VNum %d, type: %d. room.toggleflag needs subfield",
+                         GET_TRIG_NAME(trig), GET_TRIG_VNUM(trig), type);
+        }
+      }
       else if (!str_cmp(field, "north")) {
         if (R_EXIT(r, NORTH)) {
           if (subfield && *subfield) {

Holy crap, that's awesome. Thanks a ton! I'll give it a go tonight and see how it works out.

I took a hiatus and just realized that I never posted back on this. I tested it with my script that shows messages to verify my remote var's, but it seems the toggle is bugged. I hit a bug (dg_variables.c:1363: warning: statement with no effect) after verifying the code and recompiling. The line in question is 
 for (i=0; i<NUM_ROOM_FLAGS && item < 0; i++)
I took a look into it, but I'm still a white belt in my c-fu yet and the solution completely eludes me. Thanks again for coming up with the code,

Weird - that code should work. It's browser code, though, so I might have forgotten something. I'll get back to you when I get the time to actually test my code (which should be later today)

Welcor,

Hate to res an old thread, but I think this functionality may be beneficial for some others. I dropped the code into stock 3.60 code and it worked! The only exception is that it's %self.toggleflag(DARK)% when I assigned it to a room script. Awesome work!
