Did someone call? ;) Yes it was the early issues, it was issues 1-5 i
think, i was only talking to colin this evening about that, now ive
moved i really need to get on with finishing it, although i lost all my
code when i lost the sam harddrive. Ive now got a sam in a can and have
some new flash cards on order so ill get back to it and finish the
little game, maybe some articles on learning mc can be arranged.
Compiled sprites are (if im not mistaken) the fastest way to draw things
on the sam.
To use something like that from basic, you could just do the following
(this is off the top of my head after a bottle of wine, so it maybe
wrong ;) ) But each frame you could do the following (its basically a
double buffer system but from basic). When i say page 1, page 2 - i
don't mean physical memory pages, but any particular page, again from
memory it might have been the screen command that allowed you to open up
and use different screens. If you don't know then ill try and dig up
the info tomorrow.
IN BASIC:
Set the display to page 1
Update your game logic, move the cars etc
Use the MC sprite routine to draw the sprites on page 2
in the positions
Set the display to page 2, showing the sprites in the
new position
Update your game logic, move cars etc
Use the MC sprite routine to draw the sprites on page 1
in the positions
Repeat ;)
You still need to either A) handle storing what was under the sprites
and putting it back, or B) just redraw the entire screen before you draw
the sprites. B) is the easiest to start with but can be slow, but the
key is to get things working then speed them up. Doing this you are only
actually updating when you want to, you don't need interrupts, you don't
need anything clever in MC to do checking etc.
I might be completely off track here, so let me know J
Adrian.

no probs mate, I`m not exactly gonna be able to do anything with any MC
code yet anyhow, and I know your busy :) I do love looking through the
issue`s I have, it always eggs me on to do more coding, but I need to
get the early issue`s especially for the (sounding great) articles :D

I've got a site to work on tonight, otherwise I'd be dipping in my
issues to
look for you :(
