Physics is not a simple thing to add to a game btw, I can simplify the commands used to do it and others can provide physics friendly entities, but actually using it within a game is just as difficult, if not more so, than lighting or sound or story elements or huds or AI or animation. In fact all these things really require specific boards where those with the expertise can share their knowledge!
Some people may wonder why I don't put all my scripts on the store in order to monetise my skills, or indeed may wonder why I'm quite happy making changes to the engine itself without requiring any monetary reward. The simple answer is that I'm not getting any younger, I'm also in no danger of starving to death any time soon. My clients pay me crazy amounts to keep the skies safe(ish), mind you they pay equally silly amounts to those I consider are doing the opposite but hey, you need some balance in the universe.
I quite like the idea that my contributions may one day result in somebody creating a kick-a*** gaming experience based on what, quite frankly, many people consider a joke game engine.
Been there, done that, got all the T-Shirts!
