Yes, I think that would keep most people from being a game
programmer.

Twice.

Sure. Go to RDS's home site and download all the graphics
programs that have source code. Print them out. Then enter
them into your computer by hand.

Set up some coordinates for the object {x,y}
Display the object at {x,y}
to move right, add 1 to x , subtract 1 from x to move left, add 1 to y to move
down...... then display the object at the new {x,y}.
Repeat as needed.
The problem with this is that each previously displayed object will be left
behind on the screeen. So you have to work out a way to remove the object from
its previous location before displaying it in the new location.
One way to do this is to save the screen area - call it the "background" where
the object is going to be displayed before you display the object. Then when
you are ready to move the object, the first thing you do is to replace the
saved background, which effectively "erases" the object.
I'd set up each sprite something like this:
constant COORDS = 1, BKGND = 2, IMAGE = 3
object sprite
sprite = {{1,1}, {}, {} } -- object contains its own coords, space to store
the old background, and space to store the sprite image.
You've got a lot of reading to do. Believe it or not, the documentation that
comes with Euphoria contains everything you need to know to make this work.
