I really should appreciate someone helped me with this.
Here I have pictures on examples made in photoshop of it, take a look.

And here is the code I' ve done so far, wich only makes a object fallin, and then ramdomize it at the top of the screen and then down again, and again and agin...
| Code: | white = Color.new(255, 255, 255)
r0 = 0
r1 = math.random(480)
while true do
pad = Controls.read()
screen:clear()
screen:fillRect(r1, r0, 10, 10, white)
r0 = r0 + 1
if r0 == 272 then
r0 = -10
elseif r0 >= 271 then
r1 = math.random(480)
end
screen.flip()
screen:waitVblankStart(60)
if pad:start() then
break
end
end |

| you need a for loop to loop through the pieces on each draw cycle. |

you want a new "object" each time it gets to the trigger or just jump that one?
if the former, you might concider actually using "objects" (not that they are really propper classes, but they are almost as good)
ie
block = {}
block.x = 10
block.y = 10
block.vspeed = 1
kinda thing |

Yes, or ?
A function that makes this falling object, so it can fall more then one.
Sure I can write:
screen:fillRect(r1, r0, 10, 10, white) again and another random number, but I need a function that MAKES a new copie of this object. |

Perhaps you want to read the Lua book http://www.lua.org/pil/ , especially chaper 2.5. And you'll find in the starfield demo multiple objects, but moving from the center instead of dropping from top. |
