[net.micro.amiga] Bug in collision-detection

cjp@vax135.UUCP (Charles Poirier) (02/01/86)

No one's reply has reached me about my bug report of last week, so here
is a concise retry.  (I included my basic source with the original article.)
Commodore, are you listening?

Running Microsoft AmigaBasic 1.1, I encounter a bug with BOB objects
colliding with the window boundaries.  When the BOB bounces off any
window edge and then comes back to that same edge without hitting
anything else, the collision goes undetected and the BOB sails right
off the screen.  (This can occur when the BOB has acceleration towards
that edge.)  (Note, I haven't tried this using vsprite-type objects yet.)

Does anyone else see this problem?  Is anyone besides me using AmigaBasic?
Hello out there?

Hi brother,

You are not alone out there, I had the same problem too.
I also tried it with sprites, the same thing. As you said it seems to occur
if you are working with "acceleration" of objects.

Hopefully somebody at amiga will help you with this problem - in my case it
was just an experimental thing anyway - I don't rely on this to work.

I do not hope that it turns out to be true what I read somewhere else
sometimes: "They do not pay attention to ordinary customers at Commodore
very well - they only support developers".
