I have no idea how to read anybody's optimized code.

Tue, 05 Sep 2023 17:11:03 +0000

I'm not exactly new to coding the TI-84+, but I'm pretty damn new to optimizing my code. I've got the most messy and untamed programs with the most illegible and run-on code within it, and I have no clue how to fix any of it. If somebody could give me optimization tips and explain them like I'm 5 years old that would be wonderful.

Thanks!

Where'd he go? I'm checkin back on this website in 7th right now and It says his acc is deleted? Did something happen while I was on summer break?

Simon Says 2.0

I want a version of Simon Says where you use all 10 digits instead of just 5. I tried modifying the code to do this, but I was met with an "Invalid Dimension" error.

Need help with program code

Wed, 16 Feb 2022 17:57:57 +0000

So I am developing a large game where you are in charge of a toy store, and you can buy toys and whatnot. Now I am trying to create something where when I go to start the day, the program would first have a max amount of customers and then a random amount of customers between 1 and max, A. This is all working fine. The part i'm having troubles with is when I go to randomize how much stock is sold. So say I have 15 Plastic Toy, and 5 Lego Sets. So I should be able to sell a random number between 0 and 15 for the Plastic Toys, but I have a max amount of customers who can buy toys, only 1 per. So say my max amount of customers was 10, I randomized it and got 5. Then say I randomized Plastic Toys, and I got 13. I can't do this obviously, because there aren't enough customers. So I need a way to make it random between 0 and Max for the toys, but then a higher MAX of customers.

If anyone knows some code I could use, any help would be appreciated.
Thanks!

This is the part of code:

D+1->D "A is the total amount of customers you can have randInt(1,A)->A Lbl D1 randInt(0,P)->V If P>A Then Goto D1 Else A-V->A P-V->P M+(15*V)->M End Lbl D2 randInt(0,L)->W If W>A Then Goto D2 Else A-W->A L-W->L M+(45*W)->M End Lbl D3 randInt(0,T)->X If X>A Then Goto D3 Else A-X->A T-X->T M+(103*X)->M End Lbl D4 randInt(0,I)->Y If Y>A Then Goto D4 Else A-Y->A I-Y->I M+(245*Y)->M End Lbl D5 randInt(0,S)->Z If Z>A Then Goto D5 Else A-Z->A S-Z->S M+(600*Z)->M End Text(~1,1,1,"DAY: ",D Text(11,1,"Total Customers: ",A Text(18,1,"Plast Toys Sold: ",V Text(25,1,"Lego Sets Sold: ",W Text(32,1,"Metal Toys Sold: ",X Text(39,1,"Bicycles Sold: ",Y Text(46,1,"Swings Sold: ",Z

Graphing equation from lists

Tue, 14 Dec 2021 16:28:36 +0000

I need a program that can take coordinates from lists and output the formula to get the coordinates. (ex. takes table of values of X= 5,10,15 and Y= 5,10,15 then outputs Y=X or X= 1,2,3,4 and Y= 3,5,7,9 then outputs Y=2X+1) I am using a TI 83+ as my programming calculator (and only calculator).

CE Python Programming

Wed, 10 Nov 2021 00:44:26 +0000

Now that the TI 84 CE Python calculator is out, I'm now wondering if there are already games on it in Python. I'm also wondering if there's any advantage to using Python.

Algebra assistance needed

Wed, 03 Nov 2021 17:35:48 +0000

I am wondering if anyone has a way to do algebra in a program with multiple X's and covers the most things as possible because I made one that tries but doesn't use strings if anyone could help that would be appreciated Thanks!

Me?

Thu, 01 Jul 2021 22:11:10 +0000

Hi All!

Some of you might remember me. I used to LOVE programming on my TI-84+.

Might get back at it, just depends on how I feel.

I've met some awesome people here, can't wait to reconnect.

Software to draw on PC and send a picture to TI-84?

Thu, 13 May 2021 21:01:45 +0000

Can I draw an image on PC that is 96x64 pixels and black or white, and have it display on the calculator? Is there a way to display images, and does a piece of software exist to allow you to draw them? I mean I could draw it in photoshop, and save it as a bmp, can that be viewed on the TI-84?

No variables in Output()

Thu, 13 May 2021 19:56:28 +0000

I was writing a little program to bounce a letter between the sides of the screen and set up a Repeat, inside that I was attempting to use Output(1,X,"O"). This caused a domain error, and Goto left me beside the Output instruction.

Is there no way to use a variable number in Output()?

Any way to write BASIC on PC and transfer to TI-84 Plus Silver Edition

Wed, 12 May 2021 20:47:04 +0000

Was there ever a program for PC developed to allow TI-Basic entry on PC then transfer or while connected to Calculator?

Sorry for all of the posts recently. I don't mind trying to bring a little of bit of life to forums when I am learning the methods of the particular language.

Thanks, as usual for any help.

The device does not recognise the command (80070016)

Wed, 12 May 2021 20:35:52 +0000

I have a TI-84 Plus Silver Edition, works fine, everything is as it should be, connects perfectly with TI-Connect.

I just got a used TI-84 Plus today, seems to work okay, program are fine, when I try to do a backup on TI-Connect I always get the error message "The device does not recognise the command" (80070016) during the transferring of file 1/32. If I skip that, then it happens on file 2/32, etc. It cannot backup, even if I press 2ND then LINK then go to BACKUP at the same time as I press backup on PC (2 PCs actually, Windows 10 and Windows 8.1, both of which work fine with the Silver Edition.

Any Ideas on that? Obviously, I want it to be able to backup :-).

MathPrint history size?

Get a value output from a program on main calc screen (mathprint)

Mon, 10 May 2021 21:25:53 +0000

I would like to return a value that is calculated as the result of a program I have written, so that I can scroll up to it in MathPrint, on the main calculator screen, using the arrow buttons, then hit enter on it, so it is the live number on the calculator.

The problem is , after a program is Done, then if I try to scroll up, the results I have Displayed with the program, disappear, and the word Done is highlighted, and the prgmNAME is all that is displayed at that point.

Currently I have my program save the numbers I need to Variables A and B, but I would rather see them in the screen and be able to copy them using the MathPrint method.

Is that possible on TI-84 Plus?

Thanks for any help.

Just some help

Wed, 31 Mar 2021 12:46:22 +0000

Hey, I was wondering if it was possible to output two different characters on the same coordinates on the home screen (not the graph screen). For example, say I wanted to output an "N" and an "O" to make a wall; how would I go about doing that. I would like for this to be displayed on the home screen rather than the graph because of my skill as a programmer; I don't trust myself with graph programming :P

Thanks, anything helps!

Any PC application for math homework?

Fri, 26 Mar 2021 17:10:12 +0000

Hello! I do all my math (and physics) work on the computer. I have a Windows 7 desktop computer, and it isn't very fast. In fact, it tends to freeze and slow down when running numerous programs, or one that runs a lot of processes. My TI-84 is usually faster than my computer. LOL

Do any of you know of a program (for Windows 7) that can allow me to do math work and scribblings? Right now, I'm using MS Paint, and it gets the job done, but I'm getting frustrated with its shortcomings. Here's a list of the features I would like.

1: Take a snip, and paste it in, resize it, or move it on the canvas. (MS Paint lets me do this.)

2: Invert the colors of a selection (MS Paint lets me do this, as well.)

3: Draw 2D shapes.

4: Write on the canvas with my USB writing pad.

5: Draw lines easily (by pressing a key or something to toggle line mode)

6: Lock graphics, so they can't be erased. E.G. Put my formulas in the canvas, lock them, then I can scribble all over , and delete my writing and have the formulas be unaffected. (can't do this in Paint)

I don't want to pay for software, so ideally it would be free.

Thank you!

Umm, been awhile
