Widget set and handlers
Chivo  Account Info

I'm making a flexible widget (dialog control) system. I described it in detail in Upcoming TI-86 Miscellaneous Programs already with the same subject. I suppose I should've put it here instead. :-)

Oh well, it's not like anyone reads these anymore.

Questions? Comments? Money?

I just uploaded my World Sunlight Map program. It displays a map of the earth and where the sun illuminates it depending on the day of year and the hour.

Right now it displays only June 21 at 6:00AM UTC, because I'm not exactly the greatest at user interfaces. :-/

I'll be using widgets to input the month, day, and hour in a next version.

POV-Ray (www.povray.org) for the TI-86? Hmm. . .

I doubt I'd have the ability to program even a basic raytracer, but I'll give it a shot!

Graphics compression!
Levi Lansing  Account Info
(Web Page)

Has anyone noticed how much space a full screen picture takes up in an asm program?? Try 1024 bytes! I have written (and am now finishing up) a program that will convert full screen (128x64) bmp's to asm and compress them with simple vertical compression! This beats rle compression by 40-60% and will compress pictures on average to 60-80%
It'll be released as soon as I can get it compatible with everyones computers. Visiual Basic is a pain with compatability!

Re: Graphics compression!

Look for a new version of 86i Library around Dec/Jan. It uses lzss compression to compress images to ~40% to 60% and combines them into a single string to save additional space.

i've already sent in a few dbz clips for the 86.....all mre than 10 sec. .....when they finally appear in the listings i'll try to make a 2 player game and many more movies

I am working on (and nearly done) with a srite drawer for the TI-86 in basic. How it works is you type in 8 numbers 0-255 or in binary if you prefer and it converts that bit by bit to an 8x8 sprite drawn at the location you enter. From there you can flip it horizontally or vertically, invert it, move it, or draw a new one. I have drawn some pretty sweet looking pictures sitting in class already, and im thinking of making it into a "Paint" type program, but to have something like that in basic would be pointless. If you ahve any ideas, e-mail me. By the way, the program now is about 2000 bytes and takes about 10 seconds to complete a sprite.

Due to a personal breakthrough, this program is now under 900 bytes and still takes about 10 seconds to compile a sprite. If you think I should put support for different sizes of sprites, E-mail me and tell me, otherwise, you get what I give you. By the way, the first version was over 4000 bytes and took 25-30 seconds to complete a sprite (hmmm... pointless at this stage...), but it is much better now. Another thing, in my current version, you enter a HEX number instead of decimal numbers, and a visual helper will come with the program once it is finished. If you are interested or have ideas to help, e-mail me.

Basic Side-Scroller
Marcus McG  Account Info

Hey, has anyone made a game that uses the string side-scrolling method using the graph screen instead of the home screen? The Text( command is just like the Output( command, except for it runs faster and you can put more stuff on the screen... Hmmm... I was fooling around with this idea earlier and was thinking how cool it would be to have something like an RPG with this as the scenery and stuff. I haven't seen much of the RPG's currently out there, but I would assume that most of them are lame. If you know of a good game that uses this feature, please either E-mail me or reply to this message and i'll check it out.

Ok, now that i've learned some ASM, I don't plan on EVER programming in Basic again... Although maybe if i'm in class and I need a quick math program or something, I will, but basic was not meant for gaming and If you want graphics, abandon basic and jump right on to ASM. Thank you.

Does anybody know of an ASM program that can display greyscale pics in BASIC programs? I think that this would be cool to have as a title screen or whatnot. If you want one or know where to find one, email me. If there is none, I can easily make one.

Assisted Basic Grayscale
Marcus McG  Account Info

Hey, tonight I finished an ASM program that takes two regular TI-86 pics and displays them as a grayscale pic. It does this for the number of seconds specified in the real variable "TIMER". I think this is pretty sweet because it allows BASIC programmers the ability to have a grayscale title screen or something and do stuff in the background. I am going to test it some and see how some testers like it before I release it, and if anybody knows of a program like this that is already out, please tell me so I don't do something stupid...
By the way, it is about 330 bytes and uses mode 1 interrupts. Its display buffers are at $FC00 and $E800. If there is a problem that you can see with any of this, please tell me because I am no expert (yet) and I don't know everything that there is to know...

Re: Assisted Basic Grayscale

Since flickerless 4-level grayscale is impossible, I decided to make a 3-level grayscale routine. The problem is that the screen changes about 90 times per second, which is near the maximum. At this speed, gray wont flicker; however, it also doesn't seem to work. Sometimes it will display gray and others it will only display white where it should be gray. Black and white work fine but when the program is done, the part that should be gray actually IS gray and lingers for a few seconds before going away. Does anyone know what causes this? If you do, please let me know.

Hey, any ASM programmers might be interested in what I have, perhaps even a few "ASM masters". I recently finished a "Findpixel" routine that returns the byte in video memory and the offset for sprites. The reason it is so cool is that it is the fastest and smallest in the world, that I am aware of. It is 17 bytes and takes 77 clock cycles. I did not copy any routines, and this is completely 100% my idea. If you wanna worship me or find out more, email me please Notbynow@aol.com
