Re: DAAD Adventure Writer and ZX Next

So you can't clip the ula below the layer 2 area when drawing the picture and then unclip the ula area when the layer 2 picture is removed? In fact I've realized that unlike with other machines, with the way I paint the pictures in the Next (using another layer), the picture won't be erased when en...

Re: DAAD Adventure Writer and ZX Next

Just to make sure: what is considered "transparent" is the color itself, not the palette entry, isn't it?

So if I set the transparent color to 0x00 and then the palette has 5 entries with value 00, all pixels using any of those 5 palette entries index will be transparent, won't them?

Re: DAAD Adventure Writer and ZX Next

it's actually not sure there is nothing below, cause the author may not take care of deleting text when the previous location has no picture, but what it's sure is what is down there is worthless, so what I can do is make sure there is nothing below (fill the ULA zone below the Layer2 picture with t...

Re: DAAD Adventure Writer and ZX Next

Well, I always can make the converter check if there if the picture doesn't use all the colors, and then set the transparency register to a nob-used color. In case all the 256 colors are used, I can try to find which one is used less, replace it with a very similar color already in the palette, and ...

Re: DAAD Adventure Writer and ZX Next

There is one thing I'm have yet to be done: handle transparency. At the moment, I've noticed my images sometimes get some pixels as transparent, cause it happens to be just the default magenta color that is used as transparent for Layer2. Of course, I could tell user not to use that color if they do...

Re: DAAD Adventure Writer and ZX Next

I've attached a picture of how it looks. The image it's just one I had at hand, or maybe I had it far far away ;-)

Re: DAAD Adventure Writer and ZX Next

Well guys, I's almost done. I have properly loaded the picture now, although I found a bug in my converter cause I swapped R and G in the palette by mistake, but I will have the addon readdy pretty soon. When I fixed it this morning it wasn't working cause I made another mistake and set y0=yf in the...

Re: DAAD Adventure Writer and ZX Next

Hi Uto, Great news that you are adding layer 2 graphics support to DAAD! I use layer 2 as the foreground layer for displaying images in the Spectrum Next conversions of the Magnetic Scrolls games. The background layer uses either standard ULA mode or Timex hi-res mode for displaying the text. The l...

Re: DAAD Adventure Writer and ZX Next

ZEsarUX has quite powerful debugger... I find it's GUI a bit cumbersome and limiting, but compared to "no debugger at all" it's beautiful and works really well (you can even view copper code, sprite memory, etc, but most often just breakpointing into code and single-stepping over instructions check...
