Copper wait

Hi,

short and maybe stupid question: Is it possible to tell the copper to change the bg color to a specific colour, but only inside my playfield? In my case the whole screen changes to the new...

That also works for me now. But now that the clipping of the bobs work properly, I wonder if this would also work for sprites. I know that i don't have to clip sprites. But what i mean is: If i...

I think that makes sense. I already wrote some clipping code which works fine for me. But I think, in my case it might be more efficient to use your approach, because i think i will only use small...

Ok. With "reducing the bob width" you mean reducing in terms of words? Thus, if a 64x64 bob is placed at x=310, only 10 pixels can be displayed, so that the last 3 words of the bob can be ignored, 10...

Why do I have to reduce the bob width? I thought the extra 2 bytes screen buffer can be used to hide to bob in that area?

clipping problem

Hi,

I am currently coding a little asteroids-like game. That means, my sprites and bobs should be able

But why do the sprites work perfectly using the wait for line 211? They do not disappear below line 211 as the bobs do.

Hi,

Yes...ok. But is there anything wrong with it? It works, and my masks and buffers only have to be of size 16x16.

Hmmm.no. The bob is not static. I can move it over the background screen pixel by pixel. It looks good. I use

I thought that pixel shifting with the blitter was what is called barrel roll!? Not?

Well...maybe the whole thing did not work because I did not use a 16*32 BOB, but a 16x16 BOB. But it looked like the BOB was shown correctly on the screen.....
