What is the best way to get an actor to move back and forth on a platform in the sky?
Is the platform moving? If not, then you can easily just make an actor called platform and go to physics and uncheck movable. Then it can't be moved.
I'm not sure if this is what you're looking for but maybe?

I have followed the video completely, however, my enemy does not stop after it is put in initial motion... it just keeps going and leaves the left side of the screen.... my patrol right rule seems to be having no effect....?
There must be an error in your behaviors somewhere. I have source files for that tutorial on my site at the link below. That might help you out.
Once I deleted the expression and added it back, it then worked.... Not sure why though.
Glad you got it working!
