Hello,

i´m searching for the script of the StrawElevator. It is built in the DataS.gar or is it placed somewhere else?

I would like to use the elevatorMoverTrigger and the baleDestroyerTrigger for a mod, and for this i hope to understand, how the script is working. But i cannot find anything of the script.

Hope to hear from you :)

BR
