504 |
* Returns the direction to the player, if valid. Returns 0 otherwise. |
505 |
* modified to verify there is a path to the player. Does this by stepping towards |
506 |
* player and if path is blocked then see if blockage is close enough to player that |
507 |
* direction to player is changed (ie zig or zag). Continue zig zag until either |
508 |
* reach player or path is blocked. Thus, will only return true if there is a free |
509 |
* path to player. Though path may not be a straight line. Note that it will find |
510 |
* player hiding along a corridor at right angles to the corridor with the monster. |
511 |
* |
512 |
* Modified by MSW 2001-08-06 to handle tiled maps. Various notes: |
513 |
* 1) With DETOUR_AMOUNT being 2, it should still go and find players hiding |
514 |
* down corriders. |
515 |
* 2) I think the old code was broken if the first direction the monster |
516 |
* should move was blocked - the code would store the first direction without |
517 |
* verifying that the player can actually move in that direction. The new |
518 |
* code does not store anything in firstdir until we have verified that the |
519 |
* monster can in fact move one space in that direction. |
520 |
* 3) I'm not sure how good this code will be for moving multipart monsters, |
521 |
* since only simple checks to blocked are being called, which could mean the monster |
522 |
* is blocking itself. |
