Behavior tree and EQS: making an AI goes to the nearest available counter on a terminal

[alejoprieto]

Hi everybody. I’m working on a simulation of passengers flow into a terminal, but I’m stuck. It’s based on AI, Behavior Trees and EQS.

I’m using this task to find the closest counter:

Then, this to move to there:

And then, putting this together in the Behavior Tree:

But when simulate, the queue reach this point and gets stuck, and can’t find why.

Also, I need that the AI evaluate if the closest counter is taken, and if so, take the second goes to the second option.

Any idea? Thank you!
