Textured Playfields?

[Cybearg]

Would it be possible to add functionality to the standard kernel that allows one to define a "texture" for playfield pixels for each playfield row? By "textured," I mostly mean instead of drawing a solid pfpixel, it would, say, skip drawing every other line (creating a sort of ladder look) or skip drawing every 4 pixels (creating kind of a brick look), or something along those lines? I've seen it done in games made with raw Assembly, but could this be a feature added to the standard kernel or is there simply not enough time during hblank to apply a texturing based on a table like so?

 

pftexture:

0 ' 0 = solid pfpixel

0

0

8 ' 8 = ladder pfpixel

8

8

64 ' 64 = brick pfpixel

64

128 ' 128 = drawing every other pixel pfpixel

0

8

0

end

The DPC+ Kernel lets you create very detailed playfields.

Point. I wanted to avoid DPC+ because of the extra costs of a DPC+ board.

As far as I know, without DPC+, you have to use pfheights with the standard kernel to mess with the height of playfield pixels or you can have up to 32 rows with Superchip RAM.

Yeah... The problem comes in the sacrifice of pfheights for pfcolors. If only there was a way to sacrifice the ball or something for the ability to use pfheights and pfcolors together.

There is this old thread:

Awesome, thanks! Now to try getting it to work...
