510     * direction to player is changed (ie zig or zag). Continue zig zag until either
511     * reach player or path is blocked. Thus, will only return true if there is a free

513     * player hiding along a corridor at right angles to the corridor with the monster.
514     *
515     * Modified by MSW 2001-08-06 to handle tiled maps. Various notes:
516     * 1) With DETOUR_AMOUNT being 2, it should still go and find players hiding
517     * down corriders.
518     * 2) I think the old code was broken if the first direction the monster
519     * should move was blocked - the code would store the first direction without
520     * verifying that the player can actually move in that direction. The new
521     * code does not store anything in firstdir until we have verified that the
522     * monster can in fact move one space in that direction.
523     * 3) I'm not sure how good this code will be for moving multipart monsters,
524     * since only simple checks to blocked are being called, which could mean the monster
525     * is blocking itself.
