Sorry I found a much easier solution: Select all objects, then “object/Copy attributes/All physical attributes”! Simple as that…
I am sure that scripting this with python is nothing, but I am really a beginner in this, and I do not have enough time to go through all the learning curve and dig into the python scripting reference!
So if anyone has a small script which is capable of converting a selection of objects (or objects within a group) from “static” behaviour to “no cllision” behaviour in the BGE, I would really appreciate to hear from him! :o
Thanks a lot!
