I really should appreciate someone helped me with this.

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: Select all

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.

check my page
rain <-- thats something for you (no images and lot of stuff falling down)

bug: it will never rain in the lower left corner, will fix that ;)

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.
