This is asked by many people and thought I would bring it to UGX. It's a basic traverse. So use it like it should be.
Here´s the files used for make climbing zombies on eg. ladders
1. Downloaded the attached file.
2. Put in root/map_source/_prefabs
3. Open Radiant and Place.http://www.youtube.com/watch?v=x-lw1BpMESs#ws
Video will be added later to show how to change height.
I don't take ownership of this.
