Thanks, but that physics engine is to complex for me and will take me time to inplement it. I know A8 have similar feature which is px_pick() but i'm making a game like penumbra or amnesia that will run with olde video card and A8 is giving me a hard time with redenring so i'm stuck with A7. Wish someone have a code. But if i can't find a working code for A7 then i have no choice but to check newton physics.
