Attaching Graphics to Custom Types

I am totally new to blitz, and for the most part programming in general. I am working on a very simple game. What happens is you can move your ship around (that part was simple), but these balls come flying at you. I created a custom type I called ball. It has fields X#, Y#, Z#. I can change the values of the coordinates easy too, but how do I get a picture of a ball to follow each of the balls I make from the type? (I have made graphics for all these already)

for ball.ball = each ball
drawimage someimage,ball\x,ball\y,ball\z
next

you could do this.

type ball
field x,y,z
field image
end type

ball.ball = new ball
ball\image=loadimage("ball.bmp")

then in the above loop it would be.

drawimage ball\image,ball\x,blah\y,blah\z

Hope it helps.

Just make sure you free your images once your done with them.

Yeah, freeing the images was the problem. My balls became a trail of spheres! Having thousands of spheres on my screen at once wasn't good for my computer. I worked more on it and got it working.
Thank you for you help Yavin.
