485 * Modified by MSW 2001-08-06 to handle tiled maps. Various notes:
486 * 1) With DETOUR_AMOUNT being 2, it should still go and find players hiding
487 * down corriders.
488 * 2) I think the old code was broken if the first direction the monster
489 * should move was blocked - the code would store the first direction without
490 * verifying that the player can actually move in that direction. The new
491 * code does not store anything in firstdir until we have verified that the
492 * monster can in fact move one space in that direction.
493 * 3) I'm not sure how good this code will be for moving multipart monsters,
494 * since only simple checks to blocked are being called, which could mean the monster
495 * is blocking itself.
