  2. 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

  4. 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.

  10. 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!

  13. A very simple yet useful program that just has you enter in an equation (in terms of Y=) and then
    the X value of the tangent line. From there, the porgram will calculate the equation of the
    tangent line for that equation and at the entered X value. This program will also store both equations
    into the Y1 and Y2 variables of the calculator.

  17. 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.

  18. SASSIDE.8xp: This program prompts side a, angle, and side b to give you the length of your missing side. Simple as that!

    SSSANG.8xp: This program finds every angle inside a triangle by prompting side a, side b, and side c.

    TRIGLAWS.8xp: This program is more of a note program than anything. It displays the equations for both the law of sine and law of cosine. The formulas given are for area using SAS; ASA, AAS, and SSA; SSS for finding angles; and SAS for finding sides.

    TRIGVALS.8xp: This program just gives you sine, cosine, tangent, cosecant, secant, and cotangent values from any given sides.

    DISCLAIMER — Any values using square roots won't entirely work, since TI calculators make square roots decimals rather than simplifying. I'll try to find some solution to this at some point.

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! :-)
