-/*************************************************************************
-POSITION VARIABLES:
-
-        POSX is your x - position ranging from 0 to 65535
-        POSY is your y - position ranging from 0 to 65535
-            (the length of a side of the grid in EDITBORD would be 1024)
-        POSZ is your z - position (height) ranging from 0 to 65535, 0 highest.
-        ANG is your angle ranging from 0 to 2047.  Instead of 360 degrees, or
-             2 * PI radians, I use 2048 different angles, so 90 degrees would
-             be 512 in my system.
-
-SPRITE VARIABLES:
-
-    EXTERN short headspritesect[MAXSECTORS+1], headspritestat[MAXSTATUS+1];
-    EXTERN short prevspritesect[MAXSPRITES], prevspritestat[MAXSPRITES];
-    EXTERN short nextspritesect[MAXSPRITES], nextspritestat[MAXSPRITES];
-
-    Example: if the linked lists look like the following:
-         �������������������������������Ŀ
-               Sector lists:               Status lists:               
-         �������������������������������Ĵ
-           Sector0:  4, 5, 8             Status0:  2, 0, 8             
-           Sector1:  16, 2, 0, 7         Status1:  4, 5, 16, 7, 3, 9   
-           Sector2:  3, 9                                              
-         ��������������������������������
-    Notice that each number listed above is shown exactly once on both the
-        left and right side.  This is because any sprite that exists must
-        be in some sector, and must have some kind of status that you define.
-
-
-Coding example #1:
-    To go through all the sprites in sector 1, the code can look like this:
-
-        sectnum = 1;
-        i = headspritesect[sectnum];
-        while (i != -1)
-        {
-            nexti = nextspritesect[i];
-
-            //your code goes here
-            //ex: printf("Sprite %d is in sector %d\n",i,sectnum);
-
-            i = nexti;
-        }
-
-Coding example #2:
-    To go through all sprites with status = 1, the code can look like this:
-
-        statnum = 1;        //status 1
-        i = headspritestat[statnum];
-        while (i != -1)
-        {
-            nexti = nextspritestat[i];
-
-            //your code goes here
-            //ex: printf("Sprite %d has a status of 1 (active)\n",i,statnum);
-
-            i = nexti;
-        }

-TILE VARIABLES:
-        NUMTILES - the number of tiles found TILES.DAT.
-        TILESIZX[MAXTILES] - simply the x-dimension of the tile number.
-        TILESIZY[MAXTILES] - simply the y-dimension of the tile number.
-        WALOFF[MAXTILES] - the actual 32-bit offset pointing to the top-left
-                                 corner of the tile.
-        PICANM[MAXTILES] - flags for animating the tile.
-
-TIMING VARIABLES:
-        TOTALCLOCK - When the engine is initialized, TOTALCLOCK is set to zero.
-            From then on, it is incremented 120 times a second by 1.  That
-            means that the number of seconds elapsed is totalclock / 120.
-        NUMFRAMES - The number of times the draw3dscreen function was called
-            since the engine was initialized.  This helps to determine frame
-            rate.  (Frame rate = numframes * 120 / totalclock.)
-
-OTHER VARIABLES:
-
-        STARTUMOST[320] is an array of the highest y-coordinates on each column
-                that my engine is allowed to write to.  You need to set it only
-                once.
-        STARTDMOST[320] is an array of the lowest y-coordinates on each column
-                that my engine is allowed to write to.  You need to set it only
-                once.
-        SINTABLE[2048] is a sin table with 2048 angles rather than the
-            normal 360 angles for higher precision.  Also since SINTABLE is in
-            all integers, the range is multiplied by 16383, so instead of the
-            normal -1<sin(x)<1, the range of sintable is -16383<sintable[]<16383
-            If you use this sintable, you can possibly speed up your code as
-            well as save space in memory.  If you plan to use sintable, 2
-            identities you may want to keep in mind are:
-                sintable[ang&2047]       = sin(ang * (3.141592/1024)) * 16383
-                sintable[(ang+512)&2047] = cos(ang * (3.141592/1024)) * 16383
-        NUMSECTORS - the total number of existing sectors.  Modified every time
-            you call the loadboard function.

+POSITION VARIABLES:
+
+        POSX is your x - position ranging from 0 to 65535
+        POSY is your y - position ranging from 0 to 65535
+            (the length of a side of the grid in EDITBORD would be 1024)
+        POSZ is your z - position (height) ranging from 0 to 65535, 0 highest.
+        ANG is your angle ranging from 0 to 2047.  Instead of 360 degrees, or
+             2 * PI radians, I use 2048 different angles, so 90 degrees would
+             be 512 in my system.
+
+SPRITE VARIABLES:
+
+    EXTERN short headspritesect[MAXSECTORS+1], headspritestat[MAXSTATUS+1];
+    EXTERN short prevspritesect[MAXSPRITES], prevspritestat[MAXSPRITES];
+    EXTERN short nextspritesect[MAXSPRITES], nextspritestat[MAXSPRITES];
+
+    Example: if the linked lists look like the following:
+         �������������������������������Ŀ
+               Sector lists:               Status lists:               
+         �������������������������������Ĵ
+           Sector0:  4, 5, 8             Status0:  2, 0, 8             
+           Sector1:  16, 2, 0, 7         Status1:  4, 5, 16, 7, 3, 9   
+           Sector2:  3, 9                                              
+         ��������������������������������
+    Notice that each number listed above is shown exactly once on both the
+        left and right side.  This is because any sprite that exists must
+        be in some sector, and must have some kind of status that you define.
+
+
+Coding example #1:
+    To go through all the sprites in sector 1, the code can look like this:
+
+        sectnum = 1;
+        i = headspritesect[sectnum];
+        while (i != -1)
+        {
+            nexti = nextspritesect[i];
+
+            //your code goes here
+            //ex: printf("Sprite %d is in sector %d\n",i,sectnum);
+
+            i = nexti;
+        }
+
+Coding example #2:
+    To go through all sprites with status = 1, the code can look like this:
+
+        statnum = 1;        //status 1
+        i = headspritestat[statnum];
+        while (i != -1)
+        {
+            nexti = nextspritestat[i];
+
+            //your code goes here
+            //ex: printf("Sprite %d has a status of 1 (active)\n",i,statnum);
+
+            i = nexti;
+        }
+
+             insertsprite(short sectnum, short statnum);
+             deletesprite(short spritenum);
+             changespritesect(short spritenum, short newsectnum);
+             changespritestat(short spritenum, short newstatnum);
+
+TILE VARIABLES:
+        NUMTILES - the number of tiles found TILES.DAT.
+        TILESIZX[MAXTILES] - simply the x-dimension of the tile number.
+        TILESIZY[MAXTILES] - simply the y-dimension of the tile number.
+        WALOFF[MAXTILES] - the actual 32-bit offset pointing to the top-left
+                                 corner of the tile.
+        PICANM[MAXTILES] - flags for animating the tile.
+
+TIMING VARIABLES:
+        TOTALCLOCK - When the engine is initialized, TOTALCLOCK is set to zero.
+            From then on, it is incremented 120 times a second by 1.  That
+            means that the number of seconds elapsed is totalclock / 120.
+        NUMFRAMES - The number of times the draw3dscreen function was called
+            since the engine was initialized.  This helps to determine frame
+            rate.  (Frame rate = numframes * 120 / totalclock.)
+
+OTHER VARIABLES:
+
+        STARTUMOST[320] is an array of the highest y-coordinates on each column
+                that my engine is allowed to write to.  You need to set it only
+                once.
+        STARTDMOST[320] is an array of the lowest y-coordinates on each column
+                that my engine is allowed to write to.  You need to set it only
+                once.
+        SINTABLE[2048] is a sin table with 2048 angles rather than the
+            normal 360 angles for higher precision.  Also since SINTABLE is in
+            all integers, the range is multiplied by 16383, so instead of the
+            normal -1<sin(x)<1, the range of sintable is -16383<sintable[]<16383
+            If you use this sintable, you can possibly speed up your code as
+            well as save space in memory.  If you plan to use sintable, 2
+            identities you may want to keep in mind are:
+                sintable[ang&2047]       = sin(ang * (3.141592/1024)) * 16383
+                sintable[(ang+512)&2047] = cos(ang * (3.141592/1024)) * 16383
+        NUMSECTORS - the total number of existing sectors.  Modified every time
+            you call the loadboard function.

+ * id 0 is its master and it already knows the master's address. Technically
+ * every other peer who joins may get a sequential number for its id so maybe
+ * even transmitting the peer unique ids is unnecessary and we'd be easier
+ * just sending a number of players, but the less craftiness at this point
+ * in time, the better.
