Yeah. I did take a look at that map. Thats how I made the rope work. But their script is really messy... I will take a better look at it later. If anyone in the meantime knows a script or tutorial or some sort like that, please answer. But I beleave it won't be that hard if I look into their script for a little bit longer...
EDIT1: As it looks like they are using a wooden slide door to move the rope up aswell as a valve turning, both outside of the map. However, the script is a bit weird... I will try to understand it a bit more.
EDIT2: OK I solved it all. For the lantern, the static physics thing didn't work, so I tried and placing the slidedoor upside down, and it worked! After some time it's easy solving problems
Still thanks for your help.
