Problem with collision in tunnels

[LordPerenolde II]

In the image i'm posting, there's an example of what i must do. I got a cochroach level 1, and i have to make it pass through tunnels like the one in the pic. Unfortunately, it seems i can't put it in via WE, neither decreasing its collision scale to 0.01 so what am i supposed to do?

Leave a gap between clifs. Currently acording to WC3 they might as well be 1 solid wall.
Hit the "p"/"P" key to view the WC3 pathing map used. You will notice it is solid unwalkable.

To get what you are after, eithor extend the gap so as to have a one square area in the middle which is walkable, or make the roaches air units and add air pathing blockers on the tops of the cliffs.

Make the roach fly and put air blockers around

 

[LordPerenolde II]

Yeah, i forgot the air flying with land walking. That should be good! As for the air blocks, is there a limit for placing them? cuz the map is huge. Also, what's the distance from a block to the other to not allow trepassing? so i won't abuse too much.

another trick is to use a bridge. change the pathing of the bridge and give it no model, then put the bridge in the gap to let the lil roach up

There is no "abuse" issue, it has a certain pathing itself, you will realise where to place and how close to each other. As for the number, to be honest, we know of the destructibles having a certain lag-limit, i don't know if it happens with pathing blockers as well.

 

[Dr Super Good]

Try using doodads instead of destructables, I think they are less demanding.

Or try invisible platforms. They create walkable paths where they're placed. You probably won't be able to place them on the middle of the "tunnel", and if you use them a lot, the best option is to extend it, yeah.
