People get into elevators which are going in the wrong direction about elevatorsaga HOT 5 CLOSED

Good point. I have thought about this in the past and there are some todos in the code, but I have not yet figured out a good design for this.

For example, have a look at these function stubs that are not used:
https://github.com/magwo/elevatorcrush/blob/master/elevator.js#L138

Would you want the "going up" and "going down" indications to be user-code controllable? Or do you think it should be automatic? As in.. if the next queued floor is above, then the elevator reports it is going up.

In other words, I'm not sure if this "going up/down" indicator is something that can always be deduced from the current travel queue, or if it is something that the scheduler/planner code needs to inform the system about - to reveal its intentions.

I think there are pro's and cons for both solutions. At first thought it seems logical to deduce the direction from the queue, but what if my only instruction is "go to floor X"? WIll people not get on because the queue is empty upon arrival?

On the other hand, if you make the users indicate the next direction, that will lead to additional difficulty for the earlier levels. (or all people get on if no direction is indicated)

By the way, thanks for the fun game and the quick reply :)

You could by default indicate both directions, but make it user controllable.

Also, in real life, there's always that one guy that steps into the wrong elevator, so maybe add a random chance a passenger ignores the indicated direction.

Yeah.. it's probably the best design, to make it default true for both direction and then expose setters and getters in the API..

elevator.goingUp(true);
if(elevator.goingDown()) { ... }

etc.

Added support for this, just need to update the documentation.

elevator.goingUpIndicator() // true by default
elevator.goingUpIndicator(false) // set to false
