Nibbles / Discussion

We're glad you came by, but you might find what you're looking for elsewhere. TI-Basic Developer is not the site it once was. While its information on commands and other calculator features remains almost second-to-none, its forum, archives, and even hosting service, Wikidot, have been decaying for years. The calculator community would love to see what you're working on, or help you in your next coding adventure, but TI-Basic Developer is no longer the place to do it. Instead, you should head over to Cemetech (primarily American) or TI-Planet (primarily international). Both are active, well-established forums with their own archives, chatrooms, reference material, and abundant coding tools and resources. We'll see you there, we hope.

Best snake game

builderboy 11 Nov 2008 22:40

In my opinion is one of the best snake games out there. The idea of using the graph screen as the information to where the tail needs to go and such is simply genius.

I was so impressed i tried to make a version of my own. It wasn't as good :)

Kudos!

It stores the position of the very last tailpiece. Then, it pxl-tests the four squares adjacent to that position to determine which direction the tail goes. So the direction is basically encoded into the image; I'm not sure how well that would work in a dot game.

It is a very clean, well programed game.

Quick Question

Cambaby4993 10 Feb 2009 02:34

When you finish the game, by hitting a wall, eating your self, etc., the draw cursor appears and the X and Y coordinates show on the screen. Is there a way to get rid of this? I can't figure it out. (I'm a programming n00b =D)

Re: Quick Question

noahbaby94 10 Feb 2009 02:56

Yeah go to the end of the code and add this

Hello i just written by hands nibbles because i lost my cable and the program wont launch beacause of an Argument error when i press goto this is what i get :

Please help me bye bye

I am not sure if this is the problem, but try to use Pt-On( instead of Pxl-On(. That might be the problem.

The Pxl-On() syntax actually has only 2 values inputted; the X and Y position of said pixel.

Nathan (guest) 15 Dec 2016 17:18

Can you post a picture of the code so I can manually put it in?

Trenly 15 Dec 2016 18:06

Look a little further down, its posted there

Ryan (guest) 26 Apr 2013 01:40

I am typing out the code by hand, and am running into some issues. what does the L Like symbol that appears in the code stand for? Also when it says 1 space, what does that mean?

vapaavetehinen 26 Apr 2013 01:47

The little L is used to denote a list. So the little l followed by, for example, BOB is used to reference list BOB, and if it is the little L BOB(1) it stands for the first value in list BOB, where 2 would be the second etc.

(account deleted) 26 Apr 2013 10:43

To access the "litte L" in the calc's menus:

[2ND],[STAT],Right Arrow, Down

'1 space' simply means that there is a space token ([Alpha][0]),

Help!
I typed the code into my TI-82 STATS by hand, but the only thing that happens, when I run the game, is that the calculator displays "1" !!
Thank you, Bye Bye

Jake (guest) 20 Apr 2016 03:13

Ti 82 does not have lists so u either need to transfer lists from ti 83 plus or better to it or buy a ti 83 plus or better.

LeNerd (guest) 14 Nov 2013 19:19

I'm a genius! This programm only works on TI-83 and 84 :,(

IDK! (guest) 15 Nov 2013 04:54

Well, there are a couple of errors, such as the fact THERE IS LIKE FOUR QUADRANTS AND ONLY ONLY HAS A SNAKE! IN ANOTHER ALL THERE IS IS DOTS THAT MULTIPLY THEN YOU DIE!!!!!

My own errors

L1k3awh15p3r 08 Dec 2013 01:37

I had my own errors in this game as well. I double checked the code twice but there's something I missed or there's something that's wrong with SourceCode 2.5, which is how I got the game on my calculator.

The first "food" generates correctly and can be "eaten." However, the second food appears as a black box instead of an "x" and, when I try to eat it the game ends and shows a score of one. I am confused because the box isn't the correct graphic and my game ends here.

Any idea why? I don't understand most of the code so this is difficult to me.

Here's the code:

:AxesOff:FnOff 
:ClrDraw
:ZStandard
:104→Xmax
:‾72→Ymin
:ZInteger
:Line(94,0,94,‾61
:Line(0,0,0,‾61
:Horizontal 0
:Horizontal ‾61
:41→A:Ans→E
:29→B:Ans→F
:1→H:0→V
:5→S:0→θ
:Pt-On(41,‾29,2
:Repeat not(pxl-Test(N-1,M-1
:2+3int(31rand→M
:2+3int(20rand→N
:End
:Pt-On(M,‾N,2
:Pt-Off(M,‾N,3
:Pxl-On(N,M
:Repeat 0
:getKey→K
:If Ans:Then
:If H:Then
:(Ans=34)-(Ans=25→V
:If Ans
:0→H
:Else
:(Ans=26)-(Ans=24→H
:If Ans
:0→V
:End
:End
:If H:Then
:A+3H→A
:If pxl-Test(B,Ans-H)
:Then
:Text(27,34,"SCORE:",θ
:Return
:End
:Pt-On(Ans,‾B,2
:Pxl-Off(B,Ans-H
:Pxl-Off(B,Ans-2H
:Else
:B+3V→B
:If pxl-Test(Ans-V,A:Then
:Text(27,34,"SCORE:",θ
:Return
:End
:Pt-On(A,‾Ans,2
:Pxl-Off(Ans-V,A
:Pxl-Off(Ans-2V,A
:End
:If pxl-Test(B,A
:Then
:Pxl-Off(B,A
:Repeat not(pxl-Test(N-1,M-1
:2+3int(31rand→M
:2+3int(20rand→N
:End
:Pt-On(M,‾N,2
:Pt-Off(M,‾N,3
:Pxl-On(N,M
:If θ=95:Then
:Text(27,34,"WIN.
:Return
:End
:Pxl-On(62,θ
:1+θ→θ
:S+3→S
:End
:If S:Then
:S-1→S:Else
:pxl-Test(F,E-1)-pxl-Test(F,E+1
:If Ans:Then
:Pxl-On(F,E+2Ans
:Pt-Off(E,‾F,2
:E+3Ans→E
:Else
:1-2pxl-Test(F+1,E
:Pxl-On(F+2Ans,E
:Pt-Off(E,‾F,2
:F+3Ans→F
:End
:End
:End

Thanks for any help and I hope someone notices this!

The man shuddered as the shadow drew a glistening sword from his back. Creeping closer and closer with his pale eyes burning into the man, the shadow slowly raised his blade and before he could thrust it down, the man heard the shadow hiss something.
"The Shadow Clan's presence must be like a whisper. Always felt, but never seen…"

Okay, the code you posted is flawless. Check the version you typed on your calculator.

Jake (guest) 20 Apr 2016 03:18

You've probably been typing the letter "L" instead of putting in an actual list command.

Ethan (guest) 17 Feb 2017 18:55

Thanks for posting the code. I don't have a connection cable so I can't download it. I have to type it in by hand.
thank you :)

yobro96 (guest) 23 Feb 2014 22:50

how do i put the xmax and ymin on the code? i cant find it except in the window.

MasterChief2552 24 Feb 2014 18:20

You can find all window vars when you press 'vars' and then 'window' ;)
