you can do all that with triggers now, go try Cards against humanity. It's just overly complex to do with triggers and actions, but you can do something like a hidden physics ball that gets some randomness for you by setting up numbers where it falls when you start the game. 
With udon all of that is dirt simple now and no longer necessary.

udon has AI too, you can do things like build games against the computer.
