13 * The running algorithm: -CJS-
15 * In the diagrams below, the player has just arrived in the
16 * grid marked as '@', and he has just come from a grid marked
17 * as 'o', and he is about to enter the grid marked as 'x'.
19 * Of course, if the "requested" move was impossible, then you
20 * will of course be blocked, and will stop.
22 * Overview: You keep moving until something interesting happens.
23 * If you are in an enclosed space, you follow corners. This is
24 * the usual corridor scheme. If you are in an open space, you go
25 * straight, but stop before entering enclosed space. This is
26 * analogous to reaching doorways. If you have enclosed space on
27 * one side only (that is, running along side a wall) stop if
28 * your wall opens out, or your open space closes in. Either case
29 * corresponds to a doorway.
31 * What happens depends on what you can really SEE. (i.e. if you
32 * have no light, then running along a dark corridor is JUST like
33 * running in a dark room.) The algorithm works equally well in
34 * corridors, rooms, mine tailings, earthquake rubble, etc, etc.
36 * These conditions are kept in static memory:
37 * find_openarea You are in the open on at least one
39 * find_breakleft You have a wall on the left, and will
41 * find_breakright You have a wall on the right, and will
44 * To initialize these conditions, we examine the grids adjacent
45 * to the grid marked 'x', two on each side (marked 'L' and 'R').
46 * If either one of the two grids on a given side is seen to be
47 * closed, then that side is considered to be closed. If both
48 * sides are closed, then it is an enclosed (corridor) run.
54 * Looking at more than just the immediate squares is
55 * significant. Consider the following case. A run along the
56 * corridor will stop just before entering the center point,
57 * because a choice is clearly established. Running in any of
58 * three available directions will be defined as a corridor run.
59 * Note that a minor hack is inserted to make the angled corridor
60 * entry (with one side blocked near and the other side blocked
61 * further away from the runner) work correctly. The runner moves
62 * diagonally, but then saves the previous direction as being
63 * straight into the gap. Otherwise, the tail end of the other
64 * entry would be perceived as an alternative on the next move.
72 * Likewise, a run along a wall, and then into a doorway (two
73 * runs) will work correctly. A single run rightwards from \@ will
74 * stop at 1. Another run right and down will enter the corridor
75 * and make the corner, stopping at the 2.
77 * \#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#
79 * \#\#\#\#\#\#\#\#\#\#\# \#\#\#\#\#\#
81 * \#\#\#\#\#\#\#\#\#\#\#\#\#
83 * After any move, the function area_affect is called to
84 * determine the new surroundings, and the direction of
85 * subsequent moves. It examines the current player location
86 * (at which the runner has just arrived) and the previous
87 * direction (from which the runner is considered to have come).
89 * Moving one square in some direction places you adjacent to
90 * three or five new squares (for straight and diagonal moves
91 * respectively) to which you were not previously adjacent,
92 * marked as '!' in the diagrams below.
95 * .o@@! (normal) .o.! (diagonal)
96 * ...! (east) ..@@! (south east)
99 * You STOP if any of the new squares are interesting in any way:
100 * for example, if they contain visible monsters or treasure.
102 * You STOP if any of the newly adjacent squares seem to be open,
103 * and you are also looking for a break on that side. (that is,
104 * find_openarea AND find_break).
106 * You STOP if any of the newly adjacent squares do NOT seem to be
107 * open and you are in an open area, and that side was previously
110 * Corners: If you are not in the open (i.e. you are in a corridor)
111 * and there is only one way to go in the new squares, then turn in
112 * that direction. If there are more than two new ways to go, STOP.
113 * If there are two ways to go, and those ways are separated by a
114 * square which does not seem to be open, then STOP.
116 * Otherwise, we have a potential corner. There are two new open
117 * squares, which are also adjacent. One of the new squares is
118 * diagonally located, the other is straight on (as in the diagram).
119 * We consider two more squares further out (marked below as ?).
121 * We assign "option" to the straight-on grid, and "option2" to the
122 * diagonal grid, and "check_dir" to the grid marked 's'.
128 * If they are both seen to be closed, then it is seen that no benefit
129 * is gained from moving straight. It is a known corner. To cut the
130 * corner, go diagonally, otherwise go straight, but pretend you
131 * stepped diagonally into that next location for a full view next
132 * time. Conversely, if one of the ? squares is not seen to be closed,
133 * then there is a potential choice. We check to see whether it is a
134 * potential corner or an intersection/room entrance. If the square
135 * two spaces straight ahead, and the space marked with 's' are both
136 * unknown space, then it is a potential corner and enter if
137 * find_examine is set, otherwise must stop because it is not a
138 * corner. (find_examine option is removed and always is TRUE.)
