11 /* Purpose: Dungeon generation */
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".
18 * This entire file is only needed for generating levels.
19 * This may allow smart compilers to only load it when needed.
21 * Consider the "v_info.txt" file for vault generation.
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.
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.
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.
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.
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.
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.
66 * Note that the dungeon generation routines are much different (2.7.5)
67 * and perhaps "DUN_ROOMS" should be less than 50.
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.
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.
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.
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.
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
