Posted by Niklas on 21 May 2002, 18:55 GMT

For the 86-owning chess fans, Thomas Williamson has released Chessmaster 86. Features include:

  • 3 different greyscale chess sets
  • 842 bytes (!) "better than beginner" AI
  • 74 puzzles
  • 1 player, 2 player, or AI vs AI
  • autosave feature
  • total size 7kB

As always, comments and encouraging email to the author are appreciated.

Update (Niklas): Thomas has now ported Chessmaster to the TI-83 and the TI-83+. Happy chess playing!

Darn ... right when I'm making a Chess game in Basic ... oh well.
And what's with all these first post comments, even though all but one of them are first post?

In basic?

Even my (admittidely horrible) othello ai is slow in basic.

I guess a 2 player chess is alwright in basic though.

oh, and I would like to see this (or similar) on my 83+

I probably would have had a working version of my Chess game out already (the current version that's out draws pretty pictures, in black and white of course, and then dies after you try to move) except for some odd, horrible, obscure reason, it keeps on skipping one of the If Then statements ... and then gives a domain error ...

Try looking for places where you use GoTo-s to exit statements that have an end statement.

like look for something similar to the following
---------


if Ans == 2: Then
2->B
Goto A
Else
"Do Something
End

lbl a

or a goto from a loop (repeat, while...)

It seems that ti calcs see that you exit the loop (The next end statement it encounters does not take you back to the begining of the loop if there was a goto outisde of it), but the stack continues to grow.

I have *never* had that problem. Which calculators are you talking about (number-wise)?

Re: Re: Idea:

It's only a real problem if there are a lot of GoTos from block statements, which is probably the case with a chess game (which might have somewhat complicated algorithms).

I don't have too many of those ... it mostly calls various subroutines (programs that do a certain function and then return).

Oh, I had this great idea for better "on-calc" programming. You could type in ASM programs in a program editor type thing and then there could be a compile thing that would check for syntax errors and stuff and then it could compile them, wouldn't that be so cooL?

Why does the 86 get so much attention when an ASM game comes out? I know it is capable of 4-bit grayscale, but wtf? Maybe I should get an 86...

Actually, most TI-86 games use 2-bit grayscale. 4-bit is 16 shades of gray.

I remember in BASIC when I used to try to make grayscale by flickering black and white off and on. :)

Ha, yeah... or the TI-89 CyclePic command...

     23 May 2002, 23:25 GMT

Re: Re: Re: Re: Re: Re: Re: Re: Chessmaster 86 released
Chivo  Account Info

Speaking of CyclePic, I've made a fractal program that draws 2 or 3 pictures, one for each gray layer. When I CyclePic them, I get a slightly flickery grayscale image.

If you don't care for details, ignore below. These details are for 3 layers.
Layer 0 is light gray (1/7 as dark as black), layer 1 is medium gray (2/7 as dark as black), and layer 2 is dark gray (4/7 as dark as black). This allows for any combination of layers to get 8 grays (0/7 up to 7/7; easy to see if you understand binary at all).

To use these layers with CyclePic, I saved layer 0 in mandel7; layer 1 in mandel[5 and 6]; and layer 2 in mandel[1 to 4] (reverse ordering simplifies it somewhat). I just did 'CyclePic "pic",7,0.01' to see the completed image.

Note: I've found that any delay value below 0.05, even 0.04999..., has no delay at all. This might have something to do with the 200 Hz interrupt clock, or something.

Well I'm just making this up, of course, but
00 could be black
01 could be dark-gray
10 could be light-gray
11 could be white

...or something, I don't really know how it works :}

One layer typically is displayed for 2/3 of the time...So 00 would be white, 10 would be light gray, 01 would be dark gray, and 11 would be black.

Re: Re: Re: Re: Re: Re: Re: Chessmaster 86 released

More logically would to have

00 white
01 light gray
10 dark gray
11 black

due to the bit weights.

That's no different from what I described...either you have the first layer for 2/3 the time, or the second...it doesn't matter at all.

I know they're really the same, but describing the dark gray layer with bit 1 rather than bit 0 just makes more sense to me.

Okay, I'm getting sick of reading these port requests. Whenever I write a program, I write it because I think it's fun and I'm interested in it. I don't really care about chess, sorry. I will program what I want, so please stop pestering for port requests. If you want something ported, do it yourself.

The 89 is capable of 8bit, and (slowly) 16bit grayscale, but know one seems to care...

The 86 is also capable of 8-bit and 16-bit grayscale ... Levi Lansing's Animation Studio 86 makes movies in 1-bit, 2-bit, 4-bit, 8bit, and 16-bit grayscale. But I've never seen a game that's used 16-bit grayscale (or 8-bit I think) grayscale for sprites or graphics ...

     22 May 2002, 01:51 GMT


Re: Re: Re: Re: Re: Chessmaster 86 released

It's because of three reasons: having more grays is slower, and more grays (for sprites) means more storage requirements.

...therefore, anything above 4-bit (or even 2-bit) grayscale is not worth having in games. That's the way I see it. p00t!

No, no, NO! It's capable of 8 LEVEL and 16 LEVEL grayscale, not 8-BIT and 16-BIT. There is no way a TI-89 can handle 32 shades of gray, which is what 16-bit grayscale is. That would take a a) much faster processor and b) much faster refresh rate than what the 89 has.

What are you guys smoking?! 16-bit is 65536 shades of gray (2^16 = 65536, not 16^2). It's just simple arithmetic.

No, 16-bit is 65,536. Each bit is either 0 or 1, thus 2 possible values. So if you had 2 bits, then the possible values you could store would be 2 * 2. Three bits would be 2 * 2 * 2, and so on. Thus, a 16-bit number can hold 2^16 (65,536) values, typically in the range 0 - 65535.

Nah ... stick with the 89. At least it's not banned on the SAT ...
But if you care that much, get an 86. Not banned on ANYTHING (except no calculator/scientific calculator-only tests hehe). And, it's pretty good for most stuff, unless you want to do symbolic operations.
The reason why there's all this fuss about 86 ASM programs is because very few are made ... look in the file updates and you see this huge list for 83/+ and 89, and then very few for the 86.
