Hi Dizzy:
Don't understand why my last post is locked.
Anyway, to continue our last discussion, I have posted above what I
have been working on the last few weeks. I believe what I needed was
pixel perfect collision to work out my problem. I got some info off
the internet but it was C++ code. I tried to convert to simple C but
got too many errors, so T put my C code in the same program and got
it to work. I still have the same problem I have had for weeks. The
ball will NOT enter the slot in the disc. Take a look at what I have
and you will see the problem. Just click mouse in lower part of the
frame and the ball will take off. It will bounce around the diameter
of the disc but never enters the slot. Could never fix this problem.
If you have some time take a peek at what I have. Thanks!

Hi Dizzy:
Let me try this again!

It won't accept my zip file!

Here are all files except the background file.

It would not load that file for some reason.

Thanks!

Hi Dizzy:
I have written another program. This time in pure C code.
Uses the same items as the one posted before. You will have
to use your own background because the site will not upload
the one I use. It is much less complicated than the one before
but still suffers from the same problem: ball will not enter
the slot in the rotating disc. Anyway, maybe it will be able
to help someone.

Thanks

Daniel posted that I needed to rotate the mask instead of the bitmap.
I agree, but I never found a way to do this since Allegro is looking
for a bitmap, not a mask. Oh well, problems continue.

Nice work Dizzy. Although when accessing an array, it is usually stored in row major?
