Hi Aurel,

To simulate gravity, apply a small constant decrement to the y velocity

for each animation frame:

if pos.y > 0
  pos.x += vel.x
  pos.y += vel.y
  vel.y   -= grav.y
else
  'landed!
  vel.x=0
  vel.y=0
end if

The World of Tanks on the horizon?

BTW WOT was created and is still being developed in Minsk, Belarus, actually in the same office building where my eldest son's office is located. :)
