Making a minimalistic Stunts clone
Hello!
I hope that you all are doing well in this LD so far
This is a small screenshot from my current Tiled level:

I am going to expand the obvious Stunts idea to include gravity manipulation so you can drive upside down etc. and also try to cram in multiplayer splitscreen with gamepad support!
Good luck to you all!
In I am
I’ll join the jam this time again!
Tools: Webstorm, paint.net, bfxr, abundant music, tiled, blender
Libs: Three.js, howler, cannon.js
Happy coding everyone!
Procedural Music Generator
Hello!
I have put my procedural music generator online for anyone to try it out ![]()

I hope that this will be a legit LD48 tool and that you’ll find it useful!
Evil Chopper Post-jam Update
I just wanted to share my progress with my post-jam version of Evil Chopper
- Multiplayer! Up to four players, same-screen mayhem
- Gamepad support (Chrome only so far). Great for multiplayer!
- Touch device onscreen controls. Works in multiplayer as well.
- Settings for graphics, sound etc. Some browsers lie about their webgl support and then you can just force the 2d context mode
- Graphical improvements for the 2d context mode
Now I just need to create some more interesting levels and an intro screen…
Evil Chopper Post Mortem
Evil Chopper is a 3D shoot’em up made with three.js/webgl.
What went right
- Knew my libraries and tools pretty well (three.js, soundmanager2, tiled). Three.js was a bit tricky to use during LD #24 since the abstraction leaks when you want to use dynamic scenes and especially lights.
- Productivity. I am getting used to this kind of challenge now since this is my fourth LD. The brain knows what to expect by now
- My music generator delivered. It was not the greates pieces of music in the world but when I was to tired to compose anything manually, it was a saver.
What went wrong
- Time management. I spent a lot of time on tweaking graphics settings when I should have focused more on level construction and gameplay. Also, the adaption to the theme(s) was a failure mainly due to this error.
- Sleep. I should have spent more time sleeping
Overall, I think that this LD was the most fun one so far ![]()
Also, I joined the Jam because of schedule collisions. I worked alone and almost behaved like it was the 48 hour compo, but I admit that I stole some code from my previous projects to accelerate
Done!
I hope you all had a great time!
Now I will sleep
Here is a gameplay video:
… and a timelapse
Theme considerations
Thinking about the theme and not really coming up with anything good.
But I’ve always wanted to make a shoot’em up, so that is what I’ll make
In for the Jam!
Probably going to use Three.js (it’s awesome, try it!) and my own generative music system.
Some real world events are keeping me from participating in the compo. Weekend visitors
Other possible tools I’ll use: Tiled, Paint.net, Blender, Bfxr, Open MPT
Good luck everyone!
Generative Music Tool WIP
When I started to develop games, I didn’t know anything about music or how to compose a song. For my first two games I hired a composer for the music and the result was very good.
Unfortunately, you know how it is, you have to start over every time you develop a new game and buy more music. This was unacceptable for me so I thought it would be easy just to “teach” the computer some music theory and then let it compose the music in real-time instead.
I found out the hard way that this is much more difficult than it sounds. But after tons of prototypes and music theory studies, I have finally produced something that sounds reasonably good.
Generative music module output playlist
This will be turned into a tool of some sort but I don’t know the exact form.
I would love to see this tool to be used in future LDs
Done!
It is my best entry so far, but unfortunately that doesn’t mean much
I used three.js’s WebGL renderer only and coded it all in WebStorm. Tiled was used for level creation and Open MPT for music and musical SFXs.
I am quite satisfied with the result but the levels and control could use some polish. Creating animated 3D-models is something that I haven’t learned yet as well
I’m probably in!
Frameworks: libgdx or just JS + Canvas
Tools: Tiled, graphics gale or paint.net, bfxr and OpenMPT
“Done”!!!
Well, not really something to be proud of but I have learned a lot this weekend.
This was my first as3 game ever, which was a really stupid thing to do for LD ![]()
I tried to use the engine “Away 3D”, which I thought would solve my problems with the graphics, but it was not very smart since I couldn’t/didn’t have time to figure out how to solve the obvious z-fightning problems.
Also, I decided to do a lot of things procedurally: The ground mesh mess and placement of objects finally worked but it really needed a lot of debugging time. Everything pops up now but is kind of cool anyway
I should have stayed with my familiar JS framework and Netbeans.
The Children of DiscoDroid
My contribution is called “The Children of DiscoDroid” and takes place on a dance robot drifting through space. A miracle has happened and life has been created on the robot’s body (yes, it is inspired by a Futurama episode).
Every creature is sensitive to music and can be controlled that way.
You can actually test the current version (and all future current versions) here:
My LD48 Entry on Wonderfl (where I compile all code so it might not work if you try it later)
At the time of writing, you can just walk around but that will change soon. You will later be equipped with a stereo that you can play music with that. When you do that, it makes the bad guys dance and follow your moves. In that way you can defeat other bad guys or lure them into holes or other nasty places.

My Preparations
Here is a link to my starting code base/program at Wonderfl.
At the time of writing, the program just plays horrible generative music but the idea is to use the included ChordInfo class to actually have such music in the game.
You are free to use it as well if you want something like that.
The plan is to use the SiON synthesizer, which I can recommend for both music and sound effects (as an alternative to Bfxr), for playing whatever the generative music module spits out.
Changing my mind :)
After reading the book “33 strategies of war” I decided to change my previously declared tools of mass construction.
I will screw the old, well known JS and Canvas and just code everything in AS3 using Wonderfl instead.
Primitive, completely new for me and against all advice
It’s time for some crazy coding again
This is my second attempt!
I will probably use WebGL and prepare some simple 2D-tile engine that can read Tiled (map editor) output. I also plan to use Graphics Gale but I might decide to stick with Gimp.
Some other stuff that I’ll use:
* soundmanager2
* OpenMPT or Musagi
* Netbeans (mostly for Javascript but also for Ant)
* A simple starting utility library for vector math, simple geometry etc. (same as for LD22 but with some additions for WebGL stuff that I’ll post a link to later)
Sorry…
My game is to difficult. It was some kind of parameter that I set just before submitting without playtesting enough ![]()
I think it was the reaction time of the AI that I changed that made it this way.
Ah well, lesson #452 learned this weekend: Always make sure to playtest after each change. Pretty obvious really, but under these circumstances (LD noob) it happened anyway.
I have an improved version available that is much less difficult that I will continue to improve.
BTW, here is also yet another timelapse
Yay! YAE is complete!
My 48 hour game is complete!
Yes this post is a bit late…
Anyhow, the weekend was intense and I did a lot of good and bad things. Best part was that I used the Tiled level editor. Worst part was that I wasted time on my first two game ideas that were uninspiring for me
Play my super game here: YAE! You Against Everyone
Some Testable Progress
I have put a small demo online to test my code long before the deadline
It is a Html5 canvas game which means that it will only work in quite modern browsers.
Use the arrow keys to walk around. You can’t do anything else yet
.
The game is about not ending up alone and miserable in a hostile social situation.
Bully Fence Isolation Game
I am going to make a puzzle game where you are supposed to isolate the bullies from other kids by building fences!
When the bullies are all alone they will finally understand the consequences of their actions and ask for forgiveness
I think that I will add other actions beside building fences, like adding toys to attract kids etc. but I am not completely sure about all the mechanics yet.
Here is a screenshot from the level editor Tiled:

Good luck to you all!
