Hi,
Yes I saw the code example in pastebin… but since I’m no coder I have no clue what to do with it 
How can I check it in the unreal editor?
It’s no problem for the first try to no be able to disconnect it… just having something that looks like a hanging rope or cable like the example video is already very valuable.
The unity script uses pill shapes at every point (or segment) that you can then also use as sort of a collision object for the rope.
see for example Ultimate Game Tools
