834 * course never show up). Note that the treasures need not
835 * have been taken yet, just located. Hence clock1 must be
836 * large enough to get out of the cave (it only ticks while
837 * inside the cave). When it hits zero, we branch to 10000
838 * to start closing the cave, and then sit back and wait for
839 * him to try to get out. If he doesn't within clock2 turns,
840 * we close the cave; if he does try, we assume he panics,
841 * and give him a few additional turns to get frantic before
842 * we close. When clock2 hits zero, we branch to 11000 to
843 * transport him into the final puzzle. Note that the puzzle
844 * depends upon all sorts of random things. For instance,
845 * there must be no water or oil, since there are beanstalks
846 * which we don't want to be able to water, since the code
847 * can't handle it. Also, we can have no keys, since there
848 * is a grate (having moved the fixed object!) there
849 * separating him from all the treasures. Most of these
850 * problems arise from the use of negative prop numbers to
851 * suppress the object descriptions until he's actually moved
854 /* When the first warning comes, we lock the grate, destroy
855 * the bridge, kill all the dwarves (and the pirate), remove
856 * the troll and bear (unless dead), and set "closng" to
857 * true. Leave the dragon; too much trouble to move it.
858 * from now until clock2 runs out, he cannot unlock the
859 * grate, move to any location outside the cave, or create
860 * the bridge. Nor can he be resurrected if he dies. Note
861 * that the snake is already gone, since he got to the
862 * treasure accessible only via the hall of the mountain
863 * king. Also, he's been in giant room (to get eggs), so we
864 * can refer to it. Also also, he's gotten the pearl, so we
865 * know the bivalve is an oyster. *And*, the dwarves must
866 * have been activated, since we've found chest. */
