Astrovoids – Singleplayer/Multiplayer Asteroids Clone

This is a project I worked on around June 2014. It’s written in JavaScript, and uses the IvanK graphics library. The nice artwork isn’t my own! I used the Space Shooter Redux sprites, available here.

Mainly just a project I used to practice JavaScript, specifically OO JavaScript using the base.js library. Coming from nice OO languages like C#, I felt a bit hindered by the prototype based inheritance JavaScript offers. base.js sets out to help you there, well worth looking into!

The singleplayer code is available on GitHub: https://github.com/OliverF/astrovoids

The singleplayer version is available here: http://projects.bitnode.co.uk/Astrovoids
(Use WASD to move, space to shoot)

The multiplayer version is where it gets interesting. Unfortunately, I’m not happy with the performance of the multiplayer version right now, so I’ll post an update about that later.

DriveEditor – Vehicle config editor for BeamNG Drive

Another desktop application! This one was actually challenging, (which makes a change from other desktop applications I’ve made) and I learned a lot while creating a useful tool at the same time!

Well, useful if you like smashing cars in BeamNG’s Drive: a softbody car physics simulator which is much more fun than it sounds! Here’s the kind of stuff you can do after editing your vehicles:

If that’s sold you already, click here to go to the download.

So how does it work?

First, you might need to tell it where your BeamNG Drive vehicle directory is located (just go into Options->Settings), and then it will scan the chosen directory for vehicle config files. The config files are stored as .jbeam, which is some variant of JSON that I had lots of fun regex-ing to convert to valid JSON. After that, you get a screen with a huge tree on the left, and an editor on the right. You can edit values to your liking:

It saves automatically as you type, so you can hop back into BeamNG Drive and hit “CRTL+R”, and the config will be loaded!

 

Features

  • Automated scanning for .jbeam files
  • Full .jbeam parsing, allowing for total flexibility of input
  • Smart lookahead (so common config arrays will be presented in a multi-column format for easy editing)
  • Type detection for boolean values (so that editing is a checkbox) and decimal/integers (so that saving them does not save them as a string, and maintains the original type)
  • Tab index to allow you to quickly move between edit boxes by pressing tab
  • Auto update checker (can be disabled)
  • Component creation by duplicating existing components
  • Node deletion
  • Custom node adding directly from the editor

Planned features

  • (done) Type detection (so numbers will be a number box, booleans will be a check box, etc.)
  • (done) Custom node adding (So you can create vehicles from within the editor)
  • (done) Tab index (So you can tab your way through values to edit them easily)

Download

v0.5

  • Added node adding
  • Recoded a major portion of the code, improving editing speeds

Older releases:

v0.4:

  • Fixed bug where fullsize.jbeam would be incorrectly parsed
  • Added “Create component from…” function, so that parts can be duplicated and modified without editing the original
  • Patch v0.4.1: Made the “add new component” create JSON friendly validated names
  • Patch v0.4.2: Added automatic update checking (can be disabled) and “Delete node” option (right click on a node to open the menu)

DriveEditor (179.0 KiB)

(August 19th, 21:00)

v0.3:

  • Improved (but not perfected) jbeam parsing. At least now all default files should be able to be parsed
  • Added tab indexes to text boxes, so you can easily move between edit boxes by pressing tab
  • Fixed bug where text would be truncated on long labels (oops)
  • Added type detection, so values will be loaded, presented, and saved as their original types (e.g booleans will be checkboxes, integers will be saved without quotes, etc.)
  • Allowed for window resizing

DriveEditor (176.0 KiB)

v0.2:

  • Added loading screen, made it easier to browse arrays (useful for BeamNG’s use of arrays)

DriveEditor (176.3 KiB)

BitBak – Offsite Encrypted Dropbox Backup

What is the aim of this?

BitBak is an automated offsite encrypted Dropbox backup which utilizes TrueCrypt volumes to keep your data secured while storing it on the cloud. The goal is to protect your work from prying eyes and data loss at the same time by automatically encrypting then backing up your files to existing free cloud services. Sold already? Go to download!

Why take offsite backups in the first place?

If you’re a student like me, you don’t have a great deal of money to throw around. You probably develop your small or individual work either using a local repo, a cheap repo, or no repo at all. A local repo means that all your files are at the mercy of your (or your local server’s) hard drive. Same with no repo at all. A remote, free/cheap repo may one day disappear off the face of the earth, or you may consider the fact that they are cheap is a means for them to steal people’s projects illegally (in which case you should opt for a local repo if you’re the only one working on it). So essentially the risks amount to hard drive damage or theft, or remote service termination (along with all your files if you’re unlucky).

How does it work?

Very simply, it mounts a TrueCrypt volume, looks through all the folders you specify to backup, zips them up, copies them to the mounted volume, and unmounts again. In between this process, excess old backups are removed as per your specification. You can specify the interval at which to run, or you can silently run the program from the Windows Task Manager (just supply the argument “runsilent”) to allow total flexibility of when to run.

At this point, I should make it clear why I use Dropbox this. Dropbox only syncs changed blocks, rather than the entire volume, so adding small files to your volume won’t cost you a few hours of uploading. I should also point out that dynamic sized volumes will prevent a huge upload when you first create it. Of course, both of these choices are entirely up to you.

Features

  • Automated interval-timed or manual backups to an encrypted TrueCrypt volume on Dropbox
  • Multi-directory backups
  • Encrypted key storage for TrueCrypt volume key (so that the volume can be securely mounted and unmounted automatically)
  • Old backup archives automatically deleted as per your settings
  • Can be run silently via Windows Task Scheduler or batch script by adding argument “runsilent”

Instructions

  1. Create a new TrueCrypt volume. Follow the steps in TrueCrypt to create an encrypted file container (‘standard TrueCrypt volume’) inside your Dropbox folder (or anywhere, but Dropbox works best as syncing doesn’t require the entire volume to be uploaded)
  2.   Open Options->Settings to let BitBak know where your TrueCrypt volume resides, what its password is, to add directories to the backup process, and to configure a few preferences.
  3. Run a backup from the main screen. That’s all! You should be able to see all the backups in your TrueCrypt volume when you next mount it through TrueCrypt.

I’m sold, let’s try it

TrueCrypt and Dropbox are individually associated with thier own license agreements to which you must agree before utilising and installing those services. You must also agree to the license provided in ‘BitBak license.txt’ before using the program.

Versions:

v0.1.1

  • Fixed “runsilent” bug (thanks John N. for pointing this out)
  • Fixed bug where backups would ignore specified path within archive and appear in the root backup directory
