Exclude single wall from A*

Hi,

Is it possible to exclude a single wall as an A* barrier?

I am modelling a facility where most walls are also barriers to AGVs. One wall should be there for visualization but allow travellers to pass through (it has a small gap that allows AGVs to drive under it but not people).

I tried removing the wall from the A* by Q-connection, but that removes all walls. I found one workaround which involves creating a bridge at every grid node but that's a lot of work. Is there a better solution?

I'd also be happy if I can create something that looks like a wall but isn't, but my attempts at drawing a plane or cube with alpha and a texture still don't give exactly the same result for the transparency.

Any hints or solutions are much appreciated!

Hello @Mischa Spelt,

Here is a post that I think would be helpful. From what I have gathered you can create a new transparent shape that you can upload to FlexSim. Hopefully this would give you the transparent wall look you were going for.

Here are a few more searches and posts that could possibly contribute as well.

If you leave a small gap in the wall right at a node then travelers can still cross the wall.

WallGap.fsm

You can also use bridges to do this (as you mentioned).
