Hi. I noticed Hayleia's BASIC snake game on the homescreen, and I wondered how fast it could be on the graphscreen.
Made this today while seeking Weregoose's snake game code for help. (He posted code to it a while ago, and I've used it since, but idk how to contact him about it.)
It uses a trick called the pathfinding tail eater. So no lists! :D Anyhow, here's the code, at 351 bytes:
Unfortunately, the snake is quite skinny due to me using pixels (necessary point-pixel usage to the pathfinding tail eater):

I have this:
{S}^5->C
{S}/5->D
{S+1}^5->E
{S+1}/5->F
{S+2}^5->G
{S+2}/5->H
{S+3}^5->I
{S+3}/5->J
.......on until {S+7}/5->R.
There's gotta be a way to optimize this; I know the variables are in some memory location... Can someone explain how to do this?

Someone I don't trust with my calculator was sitting next to me in class, so I naturally turned on Kryolpto's password on startup option.
My password is "3.14159" (original password...) - but now when I turn on my calculator, it doesn't work. It just turns back off like I entered the wrong password...
Since I've gotten my 84+SE, I've never used Krolypto, just had it installed so I could enable it at a whim.
Omnicalc, DoorsCS, and zStart have hooks running.
TI 84+SE w/ OS 2.43 - originally 2.55, boot code changed and OS downgraded.

I seriously doubt someone managed to figure out my password and change it in the time I wasn't looking.

What should I do? I don't mind RAM clears, but Krolypto has a way around them. I really don't wanna reset the OS... I've got backed up groups in the archive and my HD crashed so I don't have any computer backups.

Here's my code:
:[00003C3C3C3C0000]?Pic1
:37?X
:53?Y
:5?D?C?F
:0?E?S?I?J?G?N
:Repeat (Y?56) or getKey(15) or (G=1)
:Pt-On(X,Y,Pic1)
:X+E?X
:Y-D?Y
:D--
:If (D>64) and pxl-Test(X+4,Y+7)
:C?D
:5?F
:4+X-B/2+E?E
:End
:If X<3
:4?X
:End
:If (X>64) and (X<99)
:63?X
:End
:If pxl-Test(X,Y+4) or pxl-Test(X+7,Y+4)
:?E?E
:End
:DispGraph
:EndI took off the stuff with the paddle movement and some more 'cause it doesn't affect the ball movement. But you can see all the code as attachment BOUNCSRC.8xp on the first post on this thread:
http://ourl.ca/17002
Anyways, the ball bounces around on a paddle 16 pxls long and the very left of it is B-8. I want to have a trail of dots like in the original game:
http://www.madebypixelate.com/games/mr-bounce
It'll describe how the ball will move until it gets to the bottom of the screen, and if the paddle is where the ball will end up, it'll describe how it'll move until it gets to the bottom again. It will also change dynamically with the paddle's movement.
Anyone have any idea how to do this?
I could make ball movement into its own loop and disp a pxl rather than the ball sprite and run it until the Y>56. But that would probably be pretty slow and take up lots of bytes.

A few months ago, I was making a program that made use of a mouse interface. I had thought that I had come up with some uber awesome optimization, but the code I came up with used more memory than if I had done it the standard way. *facepalm
I never changed it back, and now, months later, I can't understand it.
Basically, it checks the abs() of the distance the mouse is from the center of the button. Rather than a simple
If X<max and X>min and Y<max and Y>min
I came up with this:
If not(iPart((46-L₁(1))/19)) and not(iPart(43-L₁(2))/12*sigh
Can someone please fix this mess?

This is my first real Axe game, Bounce! Inspired by Mr. Bounce by Pixelate - http://www.madebypixelate.com/games/mr-bounce - and now for the TI 83/84s! It's a basically Breakout with gravity, and a few twists added in. (I haven't got the twists yet, just the basic engine.)

Bounce the ball with your paddle and try to get it to hit the targets, but don't drop it. You only have 1 life! You have about a minute to get everything before the timer runs out - you won't die when it does, but you don't get the bonus points.
My highscore so far is 630, can you beat it? (the default is 0 with "BLACKSCREEN  INC", the name of a group of my friends and I made up when we sold games in school)

I've attached prgms A, AA, BOUNCE, and BOUNCSRC. They are the level editor, the level editor's source, my BOUNCE game, and its source, respectively. I was pretty lazy when making the level editor, so it's not very good. If you screw up, exit, then type 0:Asm(prgmA) - it'll delete and reset the map.

Here's a screenshot:


I hope you like Bounce!

Weird equation variables keep appearing on my calc - a TI 84+SE, bought around March 2012. From the memory menu, here they are:
Whenever I touch them in anyway - attempt to archive, use, delete, even press the Y= button or try to graph, my calc crashes. They're in the RAM, so they disappear, but eventually they come back and trouble me again. And even though they seem to take up all that space, the RAM left doesn't change when they appear.
Every time they appear, I have to group my important in-RAM stuff and reset/try to deal with them and clear RAM anyways, then go bring everything back and reset settings. It's annoying, especially having to check for them before graphing!
I have Axe, DCS, Krolypto, MirageOS, Noshell, Omnicalc, Symbolic (not installed), and zStart (not installed) on my calc with hooks. (I think.)
And again, I have a TI 84+SE, bought around March. What is this?

I tried looking at the source of a bunch of Axe games, but all I got was a bunch of stuff like :" YTOJEB"
It made no sense!
I've tried using the input command, but I couldn't get that to work, either.

So, how?
