Description ::
A lengthy and detailed guide to programming sprites and maps in ti-basic without the use of Asm-libs. Examples are for the 83+ series, but it can be applied to the other calcs as well.

Nice... This is very well done. The information has fine structure and contains plenty of important tips, both novice and expert. The sprite rotation table near the bottom is invaluable. I can tell that you really put some effort into this—good job! :biggrin: The optimizing is good practice, but I'd like to see just how much of that every reader can change for him or herself.

[elfprince13]

Thnx...It took me three days to do this. There IS a reason I recommended it for advanced programmers. and quest could probably have about 100 bytes cut out of it too. It also took forever too find those fonts. the main website on google that had a link to them was down (fast_rpl), and I couldnt find them on ticalc.org either. even education.ti.com didn't have them

[DarkerLine]

TI-Connect has those fonts I think.

[elfprince13]

TI-Connect install a different font set, with different names. they look different too...I checked. Graph-LInk does install those fonts, but I have dial-up and my parents make me log my online minutes

Edit:

I hope Kevin sees this file.....perhaps grayscale without Omnicalc would be possible, with some modifications to the example progs in here.

sry for taking that long to add it to Omnimaga archives :ninja:

homescreen grayscale is possible, I tried, but it doesnt look fine on the SE because of the slow LCD drivers

[DarkerLine]

Yeah, well, I'm of the opinion that even if you had homescreen grayscale the homescreen ugly would outweigh the grayscale pretty.

[elfprince13]

I've done crappy grayscale with this

while 1
recallpic 1
recallpic 2
clrdraw
end

it would work for a title screen, or single screen map, and sprites could be done with a set of pointOn, pointOff commands.....it just don't lnow how well it would work.

[DarkerLine]

For drawing tiles, in theory, one could do something like:

For(each tile
RecallPic 1
draw 1st part of the tile
StorePic 1
RecallPic 2
draw 2nd part of the tile
StorePic 2
ClrDraw
End

'twould be slow though...

[elfprince13]

oh yeah...it would be fun to do just to prove a point though

[DarkerLine]

*le sigh* If only 83+ Basic had a RplcPic command...

I've found another neat trick while thinking about this though, good perhaps for grayscale text. Write something on the homescreen, then write something on the graph screen using the large font. You can then quickly switch between the two using

[Arcane Wizard]

Maybe assign something to Y1, like Y1 itself?

Y1->Y1

[Weregoose]

The best method that I can see is to prepare a STAT PLOT with [font="courier new"]{0}

[DarkerLine]

Thanks guys, but I'm afraid my next idea didn't work. Of course maybe I was setting my sights a tad too far... 8-level grayscale in pure Basic...

[elfprince13]

dang that would be sweet,
what was the logic/concept behind the idea?

[DarkerLine]

An extension of the Disp/DispGraph idea. I was thinking that the thing that makes RecallPic 1 / RecallPic 2 / ClrDraw ugly is the ClrDraw. So I was thinking of showing the homescreen, invalidating the graph screen, then displaying a picture, showing the homescreen, invalidating the graph screen, displaying the next picture. You wouldn't ever see the blank screen that ClrDraw creates. It was too slow however.

Wow, dead topic. :D

Anywho, This tutorial is now available in an html format on my site:
