Mapping barrier issue worldcraft

Hello i am learning to use worldcraft to make maps for NZP. I have a problem though, ive gotten the zombies to run over to the barrier and start hitting it, however when they knock it down they try to climb over but they cannot. I have a attached video... Please help me

The barrier is too be a bit too far up so lower it if you want the zombies to get over.

any other ideas? they still wont get over...

Fixed the video.

To answer your question, you accidentally put the window backwards. That's why the wooden pieces are falling towards you, they are supposed to fall on the other side. Zombies cannot walk through windows that are facing backwards. To fix this problem go to worldcraft/hammer and Right Click on the entity. Choose properties. Change the angle of the window so that it is facing 180 degrees in the opposite direction.

If you ever need any help, feel free to come to the chatbox on the homepage, it's much easier and I can give you step by step instructions.

probably u must have to down the wall :/

Thanks everyone
