Could somebody tell me how to mimic the phisics of a grenade that when it is trown it bounces of objects until it comes to a stop

well hopefully you know some introductory physics. All thrown objects follow the path of a parabola, defined by x=x0+Vi*t+1/2at^2 where x is the total distance, x0 is the starting position, Vi is the initial velocity a is the acceleration and t is the time. You apply the same equation for the y, except using -9.8 for acceleration. once that's modelled, you can set how you would like the grenade to bounce off an object. which would be half a prabola in the other direction. hopefully that'll get oyu started.

Not the physics he was refering too :). Theres an example in the archives.

Thanks ,i got it now .Mixed the code from the archives with the ecuation
