I am pleased to announce the reboot and near completion of the first installment of an original Slender series for the TI calculator. This game, titled 'Identity', provides a different take on the Slender storyline, while preserving the Slender-man gameplay mechanics.

Rendered in 4-level greyscale, grab your TI-83+/84+ and work your way through a dark forest at night, while being pursued by the seemingly paranormal entity. Just like in the classic PC games, don't sprint for too long or you'll lose speed for a while and won't be able to run away when you need to. Also, look at him for too long and you start seeing static and will eventually die.

As some of you know and many more don't, Slender-TI hasn't been the only project I've been working on of late. I've been actually brainstorming ideas for my own original Slender-TI series, and simultaneously working on Star Trek. This time, I've decided to bring the gCn server online first with basic functionality and then bring the client together, so I can test it as I go. Monkey has kindly offered to set me up with a skeleton and assist conceptually as my learning of socket programming advances. Anyone who wants to help on any part of this project can comment here with a method of contact and I'll be in touch.

The gCn server will be hosted on my own private server (at least for now). At my request, Deep Thought pointed a ClrHome subdomain to it. :p

In addition, I'm creating a control panel (http://sthub.clrhome.org) that will allow you to administrate your user account for the game from the computer as well. When completed, this page will allow you to change your username, password, and email address, as well as view (but not change) the server configuration file. Admins will be able to monitor and alter the users database and the loaded objects database (which is essentially the gamestate) and the server config file. It will also let them pass commands to the game server, Minecraft style, and also let them stop and start the server.

FYI: This project is my first EVER attempt at using MySQL, and so far, it is going very well!!

I am pleased to announce that my long-in-the-works "port" of the hit game Slender: The Eight Pages to the Texas Instruments graphing calculator is almost in beta stages. As such, I am opening the floor to anyone wishing to beta test...please comment below. Please read the Disclaimer below and understand the risks inherent.

I am currently finishing two final routine corrections, while Eiyeron assists in finishing the last few sprites. Additionally, I am holding the game pending an official granting of permission from Blue Isle Studios.

Disclaimer

The term "beta" applies to a full version of a piece of software that may have undiscovered glitches, glitches that may vary in severity. The purpose of beta testing is to remove the glitches, but please be aware that, if you are testing on a live calculator, unstable assembly code can cause data loss (RAM clears), Archive or OS corruption, or even in extreme cases, render your device permanently unusable, an event termed "bricking" by the community. Please use beta software with caution, and if you have reservations about testing, wait for a later beta or a stable release.

A heartfelt thank you to everyone who contributed to this project, including Zeda, Sorunome, and Eiyeron in particular, and to the entire Cemetech and Omnimaga community for their support and assistance developing this game, and of my developer career in general!

Slender: The Eight Pages is nearing completion. There are two bits of coding left to be completed, two sprites, and a map and then we are ready to beta test. As of a week ago, Slender's code has been pushed onto a private Git repository, currently only accessible to Xeda, Deep Thought, and Soruome. This has been done for the purpose of syntax spot-checking and optimization.

Unfortunately, coding on Slender is paused. I injured my hand a day ago and it is very hard to type due to the location of the injury and the bandaging on it. I hope to heal soon and resume Slender work within a few days.

Additionally, the Slender project page has been completed and is located at http://clrhome.org/slender. Please follow this blog, Cemetech, and Omnimaga for news on Slender progress. I should have a beta out soon. Anyone wishing to beta test, please comment below or on Cemetech or Omnimaga. Slender will start as a closed beta and then move into a community beta. If the game is well received, I will then port Slender: The Arrival and possibly Slender Mansion to the TI.

Last but not least, any Z80 programmers who develop for the color screen calculators are welcome to fork this project into a color version. Comment on here, Cemetech, or Omnimaga and I'll be in touch regarding Git access.

Coming soon from me, as a skill builder along the way to Star Trek, and my first step into the horror game genre as a TI developer, is a clone of Slender: The Eight Pages for the TI-83+/84+. Start off in a dark woods at night, and wander through the trees as you try to collect all eight pages before the mysterious entity called the "Slenderman" catches you.

Game based on the Slenderman creepypasta, and is a port of the game by the same name released for Mac and PC. This game is not affiliated with the makers of the original Slender in any way, but I do hope we get an official granting of permission from Parsec.

That's right—ClrHome is moving to a new host, yet again. Expect some downtime as we get stuff up and running on the new server!

On less exciting news, I accidentally left my working graphing calculator (TI-84 Pocket.fr) in a different city and will not have access to it again until the end of December, which is exactly why there haven't been any updates to Maximum Security recently. Expect some fresh downloads near the end of the month!

EDIT (2014-12-14 10:03 PST): If you can read this, welcome to the new server! We're bound to have some bugs still lying around (turns out not all servers are identical), so if you see any, please don't hesitate to contact us or comment below.

Progress on Star Trek has been coming nicely and seems to be nearing the 50% mark. Help from the programming community has been very valuable.

This game started as a passing idea for something that the CALCnet protocol could accomplish and evolved into a large-scale real-time strategy game that is nearing completion. Aspects of gameplay continue to evolve by whim as progress continues, as do ideas for seamlessly integrating server and client task management to create a pleasant gaming experience and a networking masterpiece, something previously considered impossible on a Texas Instruments graphing calculator.

Already done are most of the Main Menu and Connect Menu windows, and their related subroutines...relaying login, registration, and change info packets to the game "hub", the server-based interface that enables calc-to-calc and calc-to-server interaction. Additionally, you may file a bug report directly from your calculator. Game saves are stored server-side, not on your calculator.

Remaining to be done is the remainder of the networking, 3D motion, and the combat system, as well as the programming of the server. At the current rate of progress, I have no doubts that the game will be ready for beta testing within a few months. Stay tuned to ClrHome for the latest news on this project.

After some personal issues and a filled summer, I have found some time to get back to programming. Since this was my most interesting/promising project, I have decided to return to it. This article will refresh anyone reading it on the planned features of the game, and allow a forum to suggest more features, volunteer to assist in the making of the game, and so on.

Features:

Star Trek Multiplayer will be a fully-functional first person space shooter for the Texas Instruments graphing calculator, in the style of Star Trek combat. The view screen allows you to see directly in front of you, but hotkeys on the calculator allow you to access such things as sensors, weapons and shields controls, power configuration, communications, and much more.

To add more flair to the game, the core of gameplay is built around the DCS7 CALCnet/global CALCnet protocols, enabling unit-to-Internet communication. Every calculator running this program and DoorsCS7 may join the game and play against other players on the server. Each player creates a ship, outfits it with basic weapons and enters the server's game world.

Through gameplay, players earn three types of points. For defeating players in combat, you earn combat points which may be used to upgrade weapons systems. For rescuing other players or allying with other players, you earn diplomacy points which can be used to upgrade ship armor and shielding systems. For defeating opponents with minimal combat, you earn stealth points which can be used to buy stealth equipment, such as stronger sensors, cloaking devices, EMP guns, and the like.

An additional feature to the game...shields and weapons may be calibrated with a number, called a modulation factor. Let us assume a player's shielding systems were calibrated to 123. This means that, should a player have weapons calibrated to 123 as well, their weapons will completely breach the shields, raised or not.

Terrain on the server includes bases (neutral zones where players may go to buy upgrades and repair their ship), stars, nebulae, black holes, and other space terrain. Relevant terrain will have gravity, cause collision damage, or even heat damage.

Players may attack with more than simple weapons. Viruses may be loaded into other player's "computers" that will shut down systems, redirect power, etc. You may beam crew members into opposing ships. There are remote override commands.

The power system utilized in the game will be Star Trek realistic. The warp core will produce main power as a certain rate. That rate is proportional to the current health of the warp core system. That power is stored in the power reserve, and is depleted by systems. The backup generator also provides power, but at a much slower rate. Should the warp core be destroyed, you will need to switch to backup power. Each system works at an efficiency equal to the percentage of power available. So when the power reserve is full, all systems operate at 100%. When the power reserve is at 70%, all systems work at 70%. When the power reserve is empty, all systems fail. To conserve power, or boost your attack or defense strength, individual systems may be configured to use more or less power. For example, a phaser that is set to 150% power deals 50% more damage than normal, but also consumes 50% more power.

Sensor systems are required to lock onto ships for firing, obtain data about a ship, and track a ship at warp (up to a certain range), whether it be fleeing or coming to attack. The more upgraded your sensors, or the more power to them, the better they work. Should your sensors be knocked offline, you will need to manually find your target by steering around to bring them into focus, instead of them being automatically hit.

Firing a weapon at an enemy does not occur on a point-to-point basis. In many PTP systems, if the weapon is fired the transmission is sent directly to the opponent. However, in this game, a fired weapon becomes an entity and its speed and position are handled by the server. Should the target change speed or direction, your shot may miss and hit something else.


Technical Information:

Here I'll give a basic synopsis of how a gameplay session would work, so people interested in playing it will know what to expect, and developers will have an idea on the vision for this game.

You start the game. After moving through the title screen, you get presented with the Login or Register interface. To log in, type in your password. To register, type in a username, a password, and an email address (to send updates/file bug reports). After successfully completing one of these two actions, two small (under 100 byte) AppVars are created, one with information about your player account, the other with ship configuration data. You will then get the Connect, Settings, About, Credits, or Quit menu. Changing credentials lets you reset your username or change passwords. Settings lets you change your frame rate (how long your client waits before refreshing the map). Connecting enters the game.

When you join the game, your player account gets a one-byte ID associated with it. This ID becomes associated with your calculator's 5-byte client ID on the server (which also caps total number of players at 256). Each client saves the list of connected players into a third AppVar, with the one-byte ID for that player first and the username second (coordinates of players near you stored separately). This comes to a maximum of 2304 bytes for a full server, which is not bad at all.

In sync with your client's frame rate, the calculator will pull map data from the server and redraw the view screen (stuff directly in front of you) as well as show other things on sensors that are near you. This list of objects near you includes only objects within sensor range and nothing else, and is stored in RAM (saferam2).

There are hotkeys associated with certain actions like firing, switching equipped weapons, raising and lowering shields, changing speed, and much more. It is planned for a later release to allow you to change the default key binds within your settings (by cross-associating the default key bind to the new key bind).

When you are done playing, you press the key to disconnect from the server. At this point, the contents of the player save AppVar and the ship configuration AppVar are sent to the server for saving. Once the server indicates that you are successfully disconnected, the client destroys the local copies of those AppVars. From there, you can Connect again or exit the program.

----------------------------------

This and more is planned for this game. Anyone willing to help or test please comment below. Needed: Z80 Assembly programmers or python programmers.

So I was too optimistic in my timeline for Maximum Security. Ah well, it's still pretty close to the end.

You can download the current version of the program as well as a level pack I've been working on, with two levels. (Also, here's a screenshot of a really dumb level that just demonstrates the physics engine.)

In particular, the level editor and main menu are now integrated into the program, and loading level packs and saving progress all work splendidly. It's all essentially complete, with the exception of a simple way to go from the level editor to a testing environment for the level being worked on. (Of course, you can always just load the level pack normally and test it from there.)

But now that the core program is finished, what remains (besides documentation) is to make some levels, and this is where I make other people do my work for me. If anyone is interested in making levels for Maximum Security, you can do it now!

As we've said before, Maximum Security will depend on level packs. Anyone can create a level pack using the main program as follows:

• Select Maker from the main menu
• Choose the option "Create new level"
• Enter the name of the level pack and then its password for editing
• Use the following controls to manipulate levels:
  • + creates a level
  • – deletes a level
  • × moves a level down in sequence
  • ÷ moves a level up in sequence
  • 2nd enters the actual level editor, for which the controls are as follows:
    • MODE to enter the tile selection menu
    • TRACE/GRAPH to quickly switch to the previous and next tiles in sequence
    • 2nd to set down a tile
    • DEL to delete a tile (same as pressing 2nd when the blank tile is selected)
    • ENTER to save
    • CLEAR to quit

This is all much more complicated than it really is; you can see an actual screenshot of the level editor in a previous post. If you create a level pack you're particularly proud of, email it to me to showcase it in an upcoming gallery!

Maximum Security is. (There's already a demo here for those interested, but in any case I don't expect the final game to take more than a few days!)

It's been a while since I've posted an update on an actual calculator game (and to be honest, it's been a while since I've worked on one). Well, thanks to a combination of (unfortunate?) events, I'm back to calculator game design for the summer!

First item of business: Maximum Security, the new, haphazardly awesome puzzle platformer I started working on after Fruit Ninja was finally released. I've posted screenshots of it before, and though there hasn't been any updates on the actual game engine (which is basically complete anyway), here's are some new updates on the progress of the rest of the program.

As you can see above, the menu as described in the mockup in the previous post is completely implemented. Apparently I've never gotten around to posting screenshots of the level editor, so here they are, from a year ago.

Expect the game to be released soon—all that's left is to clean up the level editor, create some default levels, and publish! I'm really glad I picked up this project again; it feels great to finish things.

I have decided to at least make an attempt at a Legend of Zelda reboot, since my Star Trek project was a bit too involved, but I don't entirely want to shave off the concept of a playable game. I feel like my assembly abilities have increased, so I should be able to get a decent amount of this game done. That being said, if anyone with some spare time and some assembly experience is able to code graphics, movement, and AI, please feel free to comment this post and ask me for access to the repository on Bitbucket. Anyone who contributes will be listed as a co-author.

One of the features I've considered for this game for about halfway through the game, to resemble a spread of evil, the graphics to slowly darken until the screen is entirely black, requiring the use of magic to light the area around you.

Many of you Linux/Mac gurus out there may be familiar with what file integrity software is. For those of you who aren't, file integrity software works by saving data on various attributes of files, and then periodically rechecking it. Any changes to those attributes could be a sign that they have been tampered with by someone.

As the TI calculator becomes more advanced (including recent improvements in the CALCnet 2.2 application, by Kerm Martian), the likelihood may increase that tech-savvy users may find a way to get malware onto your calculator.

Calculator malware ranges in severity from a simple prank to display rude text on your screen to a program that can destroy the screen, corrupt the operating software, and brick the calculator (term meaning "render permanently unusable, software-wise").

TI-IDS is a new software project that aims to bring file integrity checks to your calculator. The software will, the first time it is run, create a database of hashes for every potential executable on your device (applications, application variables, programs, and the OS and certificate [for advanced users]). You can update this database at any time. You can also scan the files on your calculator. New files not in the database, as well as files whose hashes have changed will be returned as "problematic" when the check completes.

Many "anti-virus" programs exist on the forums at ticalc.org, but most of them are either "for fun" programs that do nothing, or simply scan by name, but not by content. This aims to be the first TI calculator program that actually has a content scan.

This program is DoorsCS compatible. Version 7.0 or later required.
Version 1.0 goals: manual database updating, manual calc scanning for file integrity issues.
Version 1.1 goals: automated database updating, via RunProg integration (see DCS7 manual), OFFSCRPT. Detecting programs with mal-opcodes.

Some of you noticed that there had been significant downtime last month. Our apologies—the free host used by ClrHome had implemented a new daily usage cap, and it turns out that some of our heavier webapps (IES and ORG in particular) tend to be a bit CPU-intensive when they're compiling. (This only affects the server, not your computer.)

In any case, we've moved ClrHome to a paid hosting plan (finally!). It's been getting close to 100% uptime in the month since we've been here, which is great. For the curious, http://mon.clrhome.org has full uptime stats and downtime logs for all the servers we use (current server at the top). If you'd like to help with the cost of hosting or to support the projects we create, we also have a PayPal account now:

And it's been another big one!

In projects, there were some small utilities released this year, which you can check out here; in addition, we're actively working on some new games that might be interesting. There's Star Trek, back in development courtesy of ACagliano and Sorunome, as well as Maximum Security, a new—well, you'll see.

On the site, we introduced a brand-new webapp called IES that lets you write code, draw images, and manage lists and matrices for your calculator projects online. We also made improvements to several existing ones, like adding autocomplete to the ORG assembly IDE and sprite image generation to Pixelscape. Many new features and a new online resource or two are planned for next year—keep an eye on the Resources page or subscribe to our RSS feed for updates!

On the official side of things, this has been the year that several new calculators have been released. Interesting ones.

Happy New Year to all of you us at ClrHome!

The Pixelscape project has received a few new updates in time for the new year! In particular, more support for exporting sprites as images and text has been added after a request was made for the feature. (As always, if you have an idea for any of our projects, feel free to shoot us an email or tell us via our contact form.)

While editing sprites on Pixelscape, there's now a new button next to Export on the bottom row labeled "Sprite." Clicking will bring up a dialog that lets you export the sprite you're currently editing in one of two ways:

	░░  ░░ ░▓▓░░▓▓░ ░▓█▓▓█▓░ ░▓████▓░  ░████░  ░▓██▓░   ░▓▓░    ░░

• Direct sprite images. You can instantly generate a URL to the current sprite as an image, so you can embed it in posts, pages—anywhere you want! Scaling and image format can both be customized. (The images above (on the left) were generated at 1, 2, 4, 8, and 16 scale.)
• Unicode sprites. The idea here is that some places (such as text forums) may not allow you to include images in posts. Instead, you can use this new feature to copy-and-paste the sprite as a sequence of Unicode block characters that look like the sprite! On the right above is such a Unicode sprite (in reverse) of the images on the left.

Both features work for monochrome sprites as well as sprites with three and four levels of gray. If you have any comments or suggestions, please leave your feedback below!
