  4. TI-84 Plus CE BASIC Programs

These files are for the TI-84 Plus CE, 83 Premium CE, and other "CE" calculators with color screens. BASIC programs are compatible with the TI-84 Plus CSE and some BASIC programs written for monochrome 83+/84+ calculators will also work correctly. Assembly and C programs must be written for the CE calculators specifically; running them on calculators with an OS newer than 5.5 requires jailbreaking the calculator.

  5. Ever hate it when you cant think of a new password?
    Well this will make one for you, just enter the length and poof a random password will appear!
    This program will work on a TI-84 CE
    Made in basic!

  6. This utility highlights which key was most recently pressed, and the "hold" option keeps all previously pressed keys highlighted.

    The "Normal" layout is what you would find on the front of your calculator
    The "Keyboard" layout corresponds to the TI-84 KE, as shown in this thread:

    This tool allows you to easily test all the keys on your keypad.
    There is no graceful exit, but pressing "ON" to quit also tests the "ON" button, so maybe that's a feature!

    Disclaimer, this will mess with your window and graphscreen format settings, and turns off all of your plots, and also uses a lot of the alphabetical variables, List1, and MatrixA.

  8. Base 3 CE is the new and improved version of the Base series, with new updates and improved gameplay and graphics. With 41 unlockable achievements, this game provides hours of play! This new version of Base Invade has color text (thanks to Dr. D'nar's CE TextLib) and custom font sprites (thanks to Iambian's CE font hooks). Base 3 CE includes more difficulty modes: Easy, Normal, Hard, Crazy!, and INSANE!!. This program has had positive feedback from others, so be sure to spend some time and check it out! NOTE: For better performance, it is recommended to use calculators with revision I or later with operating system or later installed.

  12. A TI-Basic extension written in Basic.
    Has three variable types so far:
    Array (2 dimensional)
    Empty (a Variable with no constructs, basically a string)
    Vector (basically a list with an unlimited index, but is intended for 3d programming)

  17. This is probably the best of all three versions of this program that I made!
    This is a lite version of the day of week program, which calculates the day of week of any given date.

    When you try to calculate on what day of the week a date was using the DayofWk( command, you might have noticed that the answer wasn't correct.
    I don't expect you'll have seen that though, but I've tested it with several dates and I can tell you it isn't correct.
    If you want to know more about this, you can read the 'readme' file.

    There are some important notes for some country's noted in the 'readme' file!

    Current version: 1.0.0

  19. This is a puzzle game where you are a caterpillar, inspired by the game Snakebird.
    In each level, you have to eat all of the fruit before making it to the goal. Each
    fruit makes you bigger, and because caterpillars cannot in fact phase through
    themselves, you have to be careful not to get stuck! Also, caterpillars are not
    immune to the force of gravity, so you will fall down if you aren't standing on
    something. Oh, and spikes. Did I mention the spikes? Yeah, those will kill you too if
    you're not careful. Although the earlier levels are somewhat easy, they get a LOT
    more difficult later on, providing you with plenty of playtime. There are 25 levels
    in total, and a level creator. If you create a cool level, send it to us and we could
    include it in the next game!

  20. NORMCHK is a program for checking if your data follows a Normal (Gaussian) distribution!

    Note: This Normality check relies on finding the correlation coefficient of the Normal probability or quantile (a.k.a "Q-Q") plot of a variable. There are MANY ways to assess the Normality of a sample distribution; this is one of them.

  21. Mouse

    A mouse game in ti-84 that also can serve as a tutorial on how to add controls to move something on-screen using ti-basic. This game is quite fun with 4 levels. And by looking at the source code, you can implement cursors in your ti-basic programs.

    Categorized under:
  22. A highly optimized quiz program written in TI Basic for the TI-84 Plus CE. All the problems are randomly generated and after you have finished a quiz, you can see your accuracy and the number of problems you got correct.

    Categorized under:
  23. Graph-based maze game.
    No in-game editor, so you'll have to edit the matrices manually.
    It doesn't have a win condition, so it's mostly a sandbox game for you to mess with.

    The README includes instructions for use.

    Categorized under:
  24. Instructions:
    Import 'Program.8xp' to calculator
    For a blank canvas:{
    Set R variable to 1
    For an example image:{
    Import 'Premade image matrix.8xm'
    Set R variable to 0
    Run the program
    After it displays the loaded image on the graph screen, press [ENTER] to start putting in information.
    Put an X and Y coordinate and then a color or color ID.
    The X coordinate is the horizontal position and Y is vertical.

  25. A simple program that allows you to calculate maximum heart rate, heart rate reserve, and target heart rate using the resting heart rate and percent ranges for the target heart rate (usually 60-85%). Only the TI-84 Plus CE is supported due to some of the margins I used for the text. (I haven't tested it on the base TI-84). (Please be gentle, this is my first program ever, and first time posting here. Thank you! ^_^)

    Program Name: HRCALCPE

    NOTE: When entering the lower and upper % limits, only enter the value; do not enter as a decimal and do not use any symbols. Read Me linked to this post goes more in depth.

    Please let me know of any other issues! :-)

  27. This is a port of my Doors CS 7 Clock to the CE. It's sort of a proof of concept, since literally all shells have clocks now, but still kind of cool. It uses the Celtic CE libraries and will work with any CE shell that supports monochrome icons. The program must be in the RAM to function properly.

  30. LineFinder
    This program finds the line that goes through all the given points.
    For now only up to 5 points or up to AX^4 + BX^3 + CX^2 + DX + E

    Including quality of life features like:
    Automatically make the formulas easier to read
    Graph the formula with all given points
    Displays the formula on the graph, and puts it into Y1.

    I put quite some work into this, I hope this is useful for someone.


    Bugfix added that would output impossible on possible equations

  31. With this program you'll be able to convert date formats!
    It can convert to and from Julian day numbers and Ordinal date codes. It can also convert Julian dates to Gregorian dates and reversed!

    Very much thanks to RoccoLox Programs, for allowing the use of his program!

  32. This is a tech demo showcasing how dithering allows TI-BASIC programs to display up to 225 colors instead of the usual 15. Input a seed for the randomizer, and watch as this pure TI-BASIC program draws squares of up to 225 different colors.

    This technique is a bit too slow to be practical for use in games, but it looks cool.

  33. a game similar to the long drive, (no car mechanics) where you go places, find food, oil, water, gas and diesel. make sure your car is fueled up or else you might not survive.

    my friend found as many bugs as he could, and I then fixed them, but if you find any please let me know.

    I am open to others looking at my code and using it for their own purposes, if you do anything interesting with it, message me and I will check it out.

  34. This program allows you to input two values and perform either bitwise OR or bitwise AND on them. After selecting an operator via the [1] key or the [2] key, the program ends and outputs the result on the home screen.

    Since the TI OS doesn't have built-in support for bitwise operators, this program will allow you to calculate values with these operators if you need it to do so.

  35. Made in TI-Basic for the TI-84 Plus CE, allows:

    - Flagging with Alpha
    - 3x3 removal with 2nd when #Around - #Flags = Label#
    - Pause feature w/ Clear that remembers everything in your session
    - Loading bar w/ key instructions
    - Resume menu that reveals the mine (#Mines - #Flags)
    - 15s load times to generate the board (factoring in 5s to draw the screen)

  40. The Ultimate Star Wars Space fighter game for the TI-84. Want to go flying around the sky's during class? play this amazing game. Now with a faster run time then ever before!! (There are a bunch of extra variables for drawing that will soon be shaved down though, don't worry, the license is still larger than the files)

    There might be a few bugs that are specific to how I coded it, so if you see a problem, feel free to reach out to me.

    TI-Wars is a Railshooter game Designed for the TI-84+CE. The game is about clone pilot CT-2718, known to his comrades as "Euler". The game takes place above Genoisis, at zero hour Clone Wars. It takes much inspiration from the shows "Clone Wars", "Clone Wars: The 2D Micro Series", "Republic Commando", "Bad Batch", "LSW The Complete Saga" and "Lego Star Wars The Skywalker Saga". The objective of the game is to shoot down the enemies and stay alive. Yet, the game is also purposely punishing, causing the player to die many times in the middle stages, then giving them credits to buy upgrades. These upgrades are what helps carry the gamer to the final boss and beat the game. The games emblem itself comes from the design of the crest on the Jedi Starfighter. The design of the ships concept art came from a V-19 Torrent starfighter. The game itself was entirely built in Basic and Hex. There is also a major story line, so if you want to read about the story, here it is:

    The Story of TI-Wars begins with clone CT-2718, Euler, preparing to fly out above Geonosis. The speech he is given reads:"You are CT-2718, known to your brothers as Euler, you defend the Republic Skies. As the battle bellow goes on, you are called on to fight, and give your life if needed. This is zero hour, Clone Wars."The inspiration for this comes from Republic Commandos opening speech for the first mission.
    Who is Euler:Euler, or CT-2718, is a clone pilot in the Republic Navy. Graduating top of his class with his brothers Sock-Eye and Mixer. He was assigned to the Ventolar class "Dimiscus' ', yet while in the fight, Mixer was shot, causing his systems to lose power, and drifting him into space, the ship was recovered later, with Mixer dying of asphyxiation. On the other hand, Sock-Eye was shot, and attempted a crash landing into one of the hangers, sustaining major injuries, unable to fly. Losing both of his brothers, he must take it upon himself to defeat the waves of starfighters attacking the LAAT Gunships. After the battle, Euler is promoted to squadron leader, ending up in Master Tsui Choi’s division, flying under Red Squadron. After removing himself from his hatred, and using his skills to help fly aid missions to those in need. His most notable appearances appear on the Battle of Chispohous, when he served as a co-pilot for the stealth ship IPV-2C Stealth Corvette. After Order 66, while transporting wookies, he felt a moral dilemma, and dropped them off at a fuel depot, which led to him being shot down over Kessel. His body was never found.
