494     * Modified by MSW 2001-08-06 to handle tiled maps. Various notes:
495     * 1) With DETOUR_AMOUNT being 2, it should still go and find players hiding
496     * down corriders.
497     * 2) I think the old code was broken if the first direction the monster
498     * should move was blocked - the code would store the first direction without
499     * verifying that the player can actually move in that direction. The new
500     * code does not store anything in firstdir until we have verified that the
501     * monster can in fact move one space in that direction.
502     * 3) I'm not sure how good this code will be for moving multipart monsters,
