hu... you put beer into your structs :-) to make them growing but no overfilled.

when you use registers options, do you include prototypes in your programs ?
Like that:

/* C standards */
#include

/* Amiga specifics */
#include

/* Protos */
#include
#include

int main(int argc, char *argv[])
{
 /* ... */
}

I got it to work, it was some dialog requester source i used and modified that used K&R style function headers... it did not like that.. changed the public facing ones to the more contemporary format and it linked.

thanks!

This is what InitArea autodoc says:


The multiplier must be 5. It has nothing to do with display bits per pixel.

oh, thanks for clarifying that. I think I'm guilty of not reading the docs. I wonder why 5?

Anyway, the interesting thing was I was getting the corruption on every object, and the vast majority of the objects were comprised of triangles, that 1024 would would have allowed for 170.

I had it set to 1024 so I'm just surprised I had any sort of error detected at all. I'm certainly not complaining.

Thanks!

The buffer provided to InitArea is split into two arrays 1) flag table and 2) vector table.

Flag table is byte array, while vector table holds SHORTs (x, y). This gives you the multiplier of 5 (2 * sizeof(SHORT) + sizeof(UBYTE)).

Ellipse consumes two entries, move and draw one, except when closing a polygon, in which case extra entry for the final draw is added. There are also some internal optimization where unnecessary moves are removed.

Interesting... TmpRas seems pretty logical knowing a little how the blitter works, but I was pretty sketchy about the purpose of AreaBuffer...

thanks.
