http://nerdyproductions.sobertillnoon.com/programs/sprites.php will take data from a sprite and convert it to a format or shift/flip it. It will also interlace grayscale so that it works with the TileMap that comes with ExtGraph.

nice Smileysmile.gif

btw about the grayscale interlacing does it actually interlace it to reduce the flickering effect or just for other purposes? on the 83+ we have to interlace it to reduce the flickering effect

The TileMap engine requires it to be interlaced. But sprites themselves need to be separate planes (unless ExtGraph expands to accomodate them). BTW, I had no idea that it had to be interlaced on the 83+...I made interlacing in the script for TileMap thinking that it was the only place it was going to be used...

ah cool then. I wish I had a program that takes a grayscale sprite (3 level, 4 level, 5 level, etc) and make all the layers with checkered pattern I need for making grayscale in my BASIC games, that would save me lot of time for sprite making, which is the hardest part of making grayscale games in BASIC

 could you make a demo of the grey scale effects showing how you interlaced the pics...maybe I could come up with some thing

I may have a multi-planed version (other than 1 and 2) working by the end of next week if I work on it. I've actually been fixing some things recently in it and making it remember what you last did with it (like height, width, and the like).

I need to post how I make 4-5 level grayscale sprites for xLIB someday. Its quite complicated but maybe someone could make a sprite/tilemap  editor that convert the pics into all the appropriate layers

Once you make it, my script could interlace it. (And I get multi-planing done).

would be cool Smileysmile.gif

5 level grayscale isnt really worth it for z80 calcs, 4 level do a good job, but would be cool anyway for title screens Smileysmile.gif

 well, I came up with my own way and I am working on a basic program to create a sprite and put it onto the pics of your choice with dithering, I also found that dithering/interlacing entire pics of gray scale in 4 or 5  would be incredibly slow and complex in basic (and would require a large amount of free ram, lots of masterful string manipulation, ect) so I stopped trying at it.

hope to get it up and working soon for upload.

err I think you are confusing gs levels. Actually desolate is 4 levels: black, dark gray, light gray and white. Reuben is 3 level: black, medium gray and white. 5 level is the max I could get to look decent with black, dark gray, medium gray, light gray and white but I think its better to stick with 3-4 levels so its easier to make sprites on the computer

Oh, I was talking planes (which creates 2^(number_of_planes) colors available). The script does B/W and 4-color grayscale already.
