Social Force Selective Wall Repulsion

Hello,

I am trying to create a model where the A* barriers are selectively recognized as walls in the social force system. For example in the room evacuation example attached I would like the middle barrier to either act as a wall and repulse people OR act as if there is no wall at all and freely let people through based on some variable. For example, only let people through the barrier if time is >200. The only way I can think of to start this would be to use the "neighbors with label value" rule and set the barrier label to be either off or on according to a condition, although I'm not sure how to get started with this. Attached the model for reference.

Thanks, Leo

While dividers normally don't support labels, you can (apparently) still manually add a labels node in their tree. The labels in the node will be readable through the normal syntax and even cause the labels panel to appear in the properties window.

I can't guarantee that this won't cause any issues but it seems to work so far.
