  14  * Note that Level generation is *not* an important bottleneck,
  15  * though it can be annoyingly slow on older machines...  Thus
  16  * we emphasize "simplicity" and "correctness" over "speed".
  17  *
  18  * This entire file is only needed for generating levels.
  19  * This may allow smart compilers to only load it when needed.
  20  *
  21  * Consider the "v_info.txt" file for vault generation.
  22  *
  23  * In this file, we use the "special" granite and perma-wall sub-types,
  24  * where "basic" is normal, "inner" is inside a room, "outer" is the
  25  * outer wall of a room, and "solid" is the outer wall of the dungeon
  26  * or any walls that may not be pierced by corridors.  Thus the only
  27  * wall type that may be pierced by a corridor is the "outer granite"
  28  * type.  The "basic granite" type yields the "actual" corridors.
  29  *
  30  * Note that we use the special "solid" granite wall type to prevent
  31  * multiple corridors from piercing a wall in two adjacent locations,
  32  * which would be messy, and we use the special "outer" granite wall
  33  * to indicate which walls "surround" rooms, and may thus be "pierced"
  34  * by corridors entering or leaving the room.
  35  *
  36  * Note that a tunnel which attempts to leave a room near the "edge"
  37  * of the dungeon in a direction toward that edge will cause "silly"
  38  * wall piercings, but will have no permanently incorrect effects,
  39  * as long as the tunnel can *eventually* exit from another side.
  40  * And note that the wall may not come back into the room by the
  41  * hole it left through, so it must bend to the left or right and
  42  * then optionally re-enter the room (at least 2 grids away).  This
  43  * is not a problem since every room that is large enough to block
  44  * the passage of tunnels is also large enough to allow the tunnel
  45  * to pierce the room itself several times.
  46  *
  47  * Note that no two corridors may enter a room through adjacent grids,
  48  * they must either share an entryway or else use entryways at least
  49  * two grids apart.  This prevents "large" (or "silly") doorways.
  50  *
  51  * To create rooms in the dungeon, we first divide the dungeon up
  52  * into "blocks" of 11x11 grids each, and require that all rooms
  53  * occupy a rectangular group of blocks.  As long as each room type
  54  * reserves a sufficient number of blocks, the room building routines
  55  * will not need to check bounds.  Note that most of the normal rooms
  56  * actually only use 23x11 grids, and so reserve 33x11 grids.
  57  *
  58  * Note that the use of 11x11 blocks (instead of the old 33x11 blocks)
  59  * allows more variability in the horizontal placement of rooms, and
  60  * at the same time has the disadvantage that some rooms (two thirds
  61  * of the normal rooms) may be "split" by panel boundaries.  This can
  62  * induce a situation where a player is in a room and part of the room
  63  * is off the screen.  It may be annoying enough to go back to 33x11
  64  * blocks to prevent this visual situation.
  65  *
  66  * Note that the dungeon generation routines are much different (2.7.5)
  67  * and perhaps "DUN_ROOMS" should be less than 50.
  68  *
  69  * XXX XXX XXX Note that it is possible to create a room which is only
  70  * connected to itself, because the "tunnel generation" code allows a
  71  * tunnel to leave a room, wander around, and then re-enter the room.
  72  *
  73  * XXX XXX XXX Note that it is possible to create a set of rooms which
  74  * are only connected to other rooms in that set, since there is nothing
  75  * explicit in the code to prevent this from happening.  But this is less
  76  * likely than the "isolated room" problem, because each room attempts to
  77  * connect to another room, in a giant cycle, thus requiring at least two
  78  * bizarre occurances to create an isolated section of the dungeon.
  79  *
  80  * Note that (2.7.9) monster pits have been split into monster "nests"
  81  * and monster "pits".  The "nests" have a collection of monsters of a
  82  * given type strewn randomly around the room (jelly, animal, or undead),
  83  * while the "pits" have a collection of monsters of a given type placed
  84  * around the room in an organized manner (orc, troll, giant, dragon, or
  85  * demon).  Note that both "nests" and "pits" are now "level dependant",
  86  * and both make 16 "expensive" calls to the "get_mon_num()" function.
  87  *
  88  * Note that the cave grid flags changed in a rather drastic manner
  89  * for Angband 2.8.0 (and 2.7.9+), in particular, dungeon terrain
  90  * features, such as doors and stairs and traps and rubble and walls,
  91  * are all handled as a set of 64 possible "terrain features", and
  92  * not as "fake" objects (440-479) as in pre-2.8.0 versions.
  93  *
  94  * The 64 new "dungeon features" will also be used for "visual display"
  95  * but we must be careful not to allow, for example, the user to display
  96  * hidden traps in a different way from floors, or secret doors in a way
  97  * different from granite walls, or even permanent granite in a different
  98  * way from granite.  XXX XXX XXX
