The pseudo-code could work in this fashion: * Find out where platform is * if platform cannot be reached by walk on ** go to button to call platform *** if no button/button cannot be reached: wait (auto-moving elevator? maybe someone else moves the elevator?) * wait for platform to come along * step on platform * find button to move platform and operate it * wait for platform to reach destination * step out |

Elevators and doors will probably need a "waiting" mechanism to deal with the case where multiple AI are trying to use them at once. Otherwise, think of a 3-floor, open-air elevator, where the player has gone to the middle floor and there are AIs on the upper and lower floors chasing him. Each AI would repeatedly call the elevator to their floor before the other AI had a chance to board it, causing a very stupid-looking infinite loop! As for doors, there's an analogous situation where one AI needs to close a door to get past it (in a narrow corridor), whereas another AI needs to open the same door. End result: both of them get stuck. Closest / highest-ranking / luckiest AI gets priority, perhaps. Or if the elevator floors are different distances apart, choose the AI who has the least vertical distance to travel. |

Good point. Added http://bugs.angua.at/view.php?id=519 (general resource lock to solve dead-locks when 2 or more AI try to use the same resource) with your note as basic explanation. |
