The easiest way is to use sprites. You can load 1 image (LOAD IMAGE) and apply it to many sprites. Use the SPRITE command both to create the sprite and also to change it's position.

do like this:

Global
PosY = -10 //Off the screen

//This will take a random number of the screen width
PosX = rnd (screen width())
//The you just need to create a sprite and position it
Position sprite Spritenum,PosY,PosX
//After this just make the sprite move down

I hate to tell you this since you're in the Pro-Noob Anti-Boob Justice League... but most of what you told him won't work.

If he's using classic "global" won't work. "//" works in C++ but doesn't work as a rem statement in Darkbasic. There is no "position sprite" command (just "sprite") and you've flipped the x and y coordinates on the sprite command.

ok... I was in a hurry and I don't know C++ so well but if I could make comments on DB just like that would be bether, won't you agreed?



Basicly it works like this: The repeat structure have an conter named PosY that will increase every loop. When it will stop? after it's value reaches a number equal or bigger that screen height

I don't know if classic have this commands but if not sorry but with this you can get a clue of what y need to do. I didn't test the code proprelly so... if something goes wrong Will be the disonor of the Pro nood justice league.... buts this is just code to show how to do, notto compile!!! with this code you problably have an Idea of what to do.

Sorry sorry sorry

It's ok. When you post code that's meant to not really be code type "pseudo code".

Not really. You only want to delete the sprite if you want to get rid of it totally. Using the same sprite over and over again just repositions that sprite.
