Demo of an "urgency" game

The user is challenged to drag several items
to a box before an object falls to a certain spot on the screen

The union function checks if one sprite is within another
Union of 2 rects gives the smallest rect that will enclose them both

If the union function returns the big rectangle (ho)
then that means the little rectangle is inside of it

Copy these scripts into exit frame script

on exitFrame me
  h=sprite(5).locv
  h=h+1
  sprite(5).locv=h
  checktoys
end

on checktoys
  toyflag = 0
  b= sprite(2).rect
  bl= sprite(3).rect
  l= sprite(4).rect
  ho=sprite(1).rect
  if union  (b, ho) = ho then toyflag = toyflag+1
  if union  (bl, ho) = ho then toyflag = toyflag+1
  if union  (l, ho) = ho then toyflag = toyflag+1

  if toyflag = 3 then
    beep 6  -- put whatever you want here for winning
  end if

  if sprite(5).locV > 200 then
            --- the ball goes down beyond the end level
    beep 10  -- put whatever you want here for losing
  end if

end
