Using Loops to Make Objects. Help!

[MxFxM]

Fine.
So now you want another ball to appear.
The second ball is also a ball so we can use the same blueprint.
What you will have to do is make a place to save the second ball (object):

@MxFxM

myObject ball2;

create it like that (for nr 2):

@MxFxM

ball2 = new myObject(50, 50);

(there is the other starting position btw.)
and have it do the same stuff as the first one:

@MxFxM

ball2.show();
ball2.move();

Now do that for the 3rd ball too.
