Don't Understand the SnowFall Program!! heLP! plz?

-----------------------------------

Hey there, This code was submitted by AsianSensation. I don't want to steal it or anything, but i want to make a program that is similar to it. The only problem is that i don't understand the program.. can someone explain it to me please? 
thank you so much . 
- sunny. 



View.Set ("offscreenonly") 
colorback (blue) 
cls 

type SnowType : 
    record 
        X, Y, Spd, Size : int 
    end record 

var Snow : array 1 .. 100 of SnowType 

for rep : 1 .. 100 
    Snow (rep).X := Rand.Int (5, 645) 
    Snow (rep).Y := Rand.Int (5, 475) 
    Snow (rep).Spd := Rand.Int (1, 3) 
    Snow (rep).Size := Snow (rep).Spd 
end for 

loop 
    for rep : 1 .. 100 
        Snow (rep).Y -= Snow (rep).Spd 
        if Snow (rep).Y < Snow (rep).Size then 
            Snow (rep).Y := Rand.Int (475, 575) 
        end if 
        drawfilloval (Snow (rep).X, Snow (rep).Y, Snow (rep).Size, Snow (rep).Size, white) 
    end for 
    View.Update 
    cls 
end loop 



thx - bye.

What kind of picture do you want? like a picture you found? then you use this kind of code:

var picture := Pic.FileNew ("picture.bmp") 
Pic.Draw (picture, 150, 70, picMerge)

you should have used the turing reference man, the code there works and you will learn off it if you do a little reading. i would say more, but i will wait for shorthair to appear and do it right.

anyways, read up on records in the turing reference and the tutorial in the turing tutorial part of the site. anyways, i can't really explain the code because im not too familiar with records, but you could probably figure it out by reading up on it.

there is a very nice tutorial by your favourite spammer dodge tomahawk.

basicly, I created 100 snow "objects" that have their own coordinates, speed and size. I run a for loop to generate the values for these "objects" and then in the main loop, I just subtract the position of each snowflake by it's speed. And if it goes under the 0 line, so that you can't see it anymore, I just reassign some random position for the snowflake above the screen, so the snow is continuous, and I don't have to create new snow "objects" so it doesn't take up that much memory.

I did create a better snow program, it's somewhere on compsci, it's basicly the same idea, except the snow blows in 2D, instead of going straight down.
