type in the one that in the chm files, this will help you learn what does what, as you cannot cut and paste it so it will just run.
physx take away having to make an object do something, so say you wanted to make a game where you hit a ball and it would knock down some pillars, not finding and getting code to do all would take some time, but with physx it would be the case of making a throwing system and then making the objects dynamic, so when you threw the object with luck it would hit the pillar and fall over.
just remember the could does all the work you just have to work out how to use it.
not saying I can do it, but what would you want to see in a tutorial?
