Just to say that I have managed to code a rotating train

I'm still testing if it does not break other things, but for instance it works very well !!!
I have always dreamed of such feature...
It still use the func_train, you just needs to give an "angle" key for each path_corner you have.
I have modified the func_rotating too, it can be used to have sine (like sinus) move instead of linear, in other word it's just like the func_pendulum but with greater flexibility. I'm planning to make another variation to produce some "shutter in the wind in a ghost town" effect.
