    This is my lamest posting ever, so I’ll keep it short.

    Yes, I want to be in even though I’m still sick from Gamescom week, yes, I will use Unity as usual because it’s the tool I know best now, and yes, I love Ludum Dare.

    Here’s hoping that I can actually deliver this time. My ego needs it.

    Spielsalon Kassel


    Are you near or in Kassel, Germany, at the weekend from 29th November to 1st December? There’s a local game jam going on, in the context of the Spielsalon 2013 (a festival about author games, i.e. games by individual people, often artists). This means you can also attend talks and workshops before the jam!

    As usual the game jam itself will be about making a game in 48 hours. It will take place in a bar.

    • no fee for attendance
    • a place to sleep will be provided by folks from Kassel (couchsurfing)
    • the theme will be given at the beginning, but you can choose your own tools of course
    • make friends in teams

    More information (in German) is here. Use this form to enter (20 participants max)!

    BLAM BLAM PLANET post-jam update

    Posted by (twitter: @RatKingsLair)

    Just a little update for our LD27 entry, BLAM BLAM PLANET. I added visual feedback when the ammo is empty, and a hotseat coop multiplayer mode (i.e. you need an XBox controller to control the second player).

    It also got its own website!

    BLAM BLAM PLANET – Post Mortem

    Posted by (twitter: @RatKingsLair)
    Wednesday, August 28th, 2013 1:53 pm

    This is a slightly edited version of my post on our own blog!


    Back in April, Ludum Dare 26 was not so great, as I couldn’t participate. It was right after the AMAZE IndieConnect, and this convention drowned my energy so much that I got sick. All I made was some visual experiment, which I couldn’t develop much further because the headaches got too strong – partly because of my chosen art style. :-P

    So, last week’s Ludum Dare 27 was much better in this regard! And after kernel exception, this is the second Ludum Dare we entered together (thus being a Jam entry, not a Compo entry). We had a lot of fun, but also some problems, of course.

    Our entry is a first-person shooter, with a little twist: you have five weapons, and every 10 seconds your current weapon switches automatically to another one, randomly selected. And there are “floating devices” all over the world (= a medium-sized planet) which you have to stand near for 10 seconds, so a bunch of power-ups get spawned (ammo and health packs). Enemies spawn in waves every 10 seconds. And when you collect ammo, you basically get an additional 10 seconds of shooting time.

    As you might know, this Ludum Dare’s theme was “10 Seconds“, and we called the game BLAM BLAM PLANET.

    blam blam planet

    After some minutes of playing the game becomes quite intense, because more and more enemies spawn. If you just run and shoot around instead of waiting at a device now and then for a while, you will soon run out of power-ups, and thus health and ammunition. So it’s even a bit tactical, one might say.

    The development of the game had its ups and downs, but it went well in most cases.

    On Saturday, we thought of the game idea by talking about different possibilities and going for a walk. Ludum Dare starts 3 am here in Germany, and if I remember correctly, it already was afternoon when we agreed on making a first-person shooter, because we never did one really. To make it more interesting we decided that the setting should be on a round surface, which meant the game would need spherical gravity for all entities.

    At the beginning we named the game “GLITCHIG”, because we wanted a broken look and have destructible environment, so lots of triangles are flying around. RottenHedgehog started building a neat planet surface with some asteroids around it in 3dsmax, while I started to let my character controller be influenced by gravity pointing to the level origin. Shooting little spheroids was also a priority.

    spherical gravity

    So both Saturday and Sunday were all about getting this right: a planet, a player, a weapon, some enemies walking around. Mostly I tried to get it all working smoothly, by getting the physics of the character and the weapon right. But the hardest part were the enemies and their AI on the round planet. For this, I searched for some code for creating the vertices of a geosphere, mapped this via raycasts on the planet geometry and connected the resulting points – those were then the nodes for the enemies’ path-finding. Just letting the enemies walk directly towards the player probably would have been much easier, but less fun to create. ;-)

    Another nice part of development was inventing the different weapon effects – two weapons in the final game deform the geometry, so I can push the vertices of the planet around a bit when the bullets hit something. It looks quite ace. As “glitches” was our personal theme from the start we knew the geometry would look strange and broken the more you use this weapon and we embraced that. In fact, when I last played the game, I fell through the level and I could attack all the enemies from below while they couldn’t see me – but that also meant I didn’t get any new ammo, so it was okay.

    RottenHedgehog was mostly busy with modeling the three types of enemies and animating them. They look kind of deformed, emphasizing their low-poly nature, and it really looked well. Especially when she added the walk/fly animations, which are really hilarious. When the enemies spawn in masses it becomes a really cool effect.

    In order to tie the look together, she also created a color code in Photoshop. After that, the game looked “right”, as the colors of most assets didn’t need much tweaking afterwards. Having only very few placeholder art from early on really helped the motivation somehow.


    Sunday evening RottenHedgehog also started to make some sounds for walking and shooting by using our laptop’s inbuilt microphone. High tech! All the sound effects you hear in the game are actually RottenHedgehog‘s voice. :-) Adding sounds instantly made the game more alive; in the end, you can’t have enough of them – that’s why she made more on Monday, along with the art for the bullets and particle effects.

    On the third day the theme of “10 Seconds” still wasn’t in the game, and I thought long and hard about how to implement it. I weighed the pros and cons inside my head of different game mechanics, like “every 10 seconds, you have to collect new ammo” or “activate 10 bases, 10 seconds each, and then you won (whatever that means)” – and only when I finally began to create the five different weapons and let the enemies spawn in waves, the probably best restrictions (automatic weapon switching, time-limited ammo, etc.) came naturally. So there’s that: sometimes tinkering too long can be bad, and you should just “do it”, I guess.

    In the final hours I was able to quickly implement the main menu and a death screen, which always is satisfying as it ties the game together and makes it look complete. RottenHedgehog made the logo and the button graphics, and also captured a video of the game.

    So, that’s how it went. Let’s take a look on some quick facts about …

    what went wrong!

    • Finding the idea was hard for us, as we couldn’t agree on most things. In the end, the game we created isn’t as innovative as I would have liked, but at least it’s superfun to play this time!
    • As we struggled with the idea, it’s clear the theme didn’t help much. Although “10 Seconds” is in the game more than once now, it feels a bit off.
    • On Monday I nearly lost the will to finish the game, because of the lack of a clear direction regarding the gameplay, caused by the theme.
    • RottenHedgehog had some severe problems with the CAT animation system in 3dsmax. It seems to be buggy as hell, and I heard her cursing a lot. ;-)
    • There are no game-breaking bugs in the game, phew – only some small stuff, like resetting the option settings when you open the “Options” menu. The bigger problem might be that the game is “broken by design”, because of the Glitcher (the weapon that deforms the planet’s geometry) – we should have used this feature more often, so it doesn’t feel strange when you fall through the geometry.
    • A lot of feedback is missing, like some kind of visual hint when you got hit, or a sound and animation when the ammo is depleted. Also, the “story” isn’t communicated in the game: you don’t know what you’re doing here, why your weapon system is defective, and why you have to stand near the floating devices. (Some people didn’t understand that the enemies only start to spawn when you do that for the first time.)

    what went right!

    • It’s always great to work together with RottenHedgehog, because we know exactly what each of us can do, and how. While I do the scripting, she does the modeling, texturing and sounds. Perfect team work – all in the same room!
    • I set up an SVN repository, which sped up the work flow incredibly, and also saved my ass at least once when I accidentally deleted some files in the Unity project folder.
    • I prepared some basecode a day before Ludum Dare, by skimming through my former projects and picking useful helper code snippets. Having a basic character controller, path-finding, simplex noise and other functions ready before you even have to think about where to find them is wonderful!
    • RottenHedgehog recorded the sounds with her own voice and distorted them in Audacity, which was much faster (and cooler) than trying to find sound effects on freesound.org with the right license.
    • The abstract, low-poly, somewhat “broken” graphics style looks quite well and gets very positive feedback, even without textures – AND it also was done very quickly.
    • The five weapons are fun and pretty diverse. This way, the whole game is fun enough for a few minutes, and that’s the most satisfying part of this Ludum Dare for me.
    • Before we started I thought the spherical gravity might not work at all, neither as a gameplay mechanic nor as a visual style. I especially was concerned with this style the player would see too much sky and not enough ground surface. In the end, with the recoil of some weapons (so you fly away, looking down) and the high amount of flying enemies, this wasn’t any problem.

    what we learned!

    • Due to the lack of time at the end, the balancing is kind of subpar. Good thing the game just is an endless shooter, and thus it is good enough. It’s also cool that you can “learn” the game, as using the floating power-ip devices is important, but not obvious. Always try to add stuff like that.
    • “Crappy” graphics often look awesome when animated and with a nice shader. ;-) Coherence is very important though – that’s why creating a color code sheet early in the process is a must.
    • Try to not make any placeholder art, because it either means you will have to make an asset twice – or it will be in the final game.
    • Even if you lose motivation near the end, at least try to give the game an ending. Sometimes, it helps to finish the game nonetheless, because this, this and, oh, that too, has to be done before the game can have an ending and be called “done” …
    • Three days are still too long for me, because it automatically makes the project too ambitious.
    • Every time I see a Unity project with the standard Unity button graphics I get the urge to close it instantly. Really, it’s easier than most things in Unity to add some custom button graphics and a downloaded font to the GUI skin. Give your game some love!

    As much as I’d want to extend the game a bit, like adding more levels, I don’t think it will get much bigger than now. The feedback of players and Ludum Dare ratings is really nice so far, but I don’t know if having more enemy types and whatnot would increase its popularity. An online highscore would be nice, though, so maybe I will add that.

    Thanks for reading this post-mortem, and I hope you had as much fun with this Ludum Dare as we had. If you want you can play and rate BLAM BLAM PLANET here! :-)

    It’s called BLAM BLAM PLANET and was done in 3 days. Yay us!

    0005 2013-08-27 01-44-36-01

    We even followed the theme – your weapon system switches your current weapon every ten seconds, and enemies spawn every ten seconds. Yeah, it’s a bit crude, but at least you can play it longer than ten seconds. ;-)

    Play it, if you dare!

    Actually making an FPS

    Yes, we make an FPS, although 7DFPS is over. The theme didn’t gave us good ideas (good in the sense of feasible), so we’re doing something new for us (we never did an FPS with shooting before, as far as I remember). We will add the theme afterwards – like “your weapon changes every 10 seconds” or so.

    Some basic gameplay and graphics were done today, so we can go to sleep now.


    In again for the jam

    Team Rat King will try to participate in this honorable event once again!

    As I (ratking) seem to have forgotten everything about any other tool (like Flash, Haxe, or Visual Studio), I will use Unity as game engine with the language C# for scripting. My own base code, which consists of some helper classes (partly stuff written myself, partly stuff copied from the Unify wiki or other places, plus iTween, plus some useful shaders) and a very simple rigidbody-based character controller, will hopefully make the development faster so I can concentrate on the actual gameplay. I might include cInput 2.

    My partner, ratqueen, will probably do the graphics, with Photoshop and 3dsmax.

    If there will be any sound, we will use Audacity, sfxr and/or whatever generates some interesting notes.

    Good luck and much fun to all entrants!


    Tale of Scale – Post Mortem

    Posted by (twitter: @RatKingsLair)
    Monday, December 24th, 2012 2:52 pm

    This article is a copy from my blog.

    On December 15th, Ludum Dare 25 started. As usual, this was an interesting experience, as exciting and awesome as it was soul-crushing. But this might be just me.

    Like before, I didn’t have the right idea for the theme. This time it was “You are the Villain”, which was a better theme than usual, but unfortunately it only triggered gameplay concepts for me which all belong into the “that was already made before” category. So the first thing coming into my mind was “Dungeon Keeper”, and as much as I’d like to do a game similar to this awesome piece of gaming history, it just would be a clone without the right amount of innovation (or would it?). Among the other ideas I had were a “Pirates!” roguelike, a game where you control four bandits at once (robbing innocents and wandering around) and a board game creator where you’re the dungeon master placing the monsters (think “HeroQuest” or so).


    None of these ideas were the incentive for me to actually start developing (although I still like them). In my mind, I combined them, added features and the result got bigger and bigger, and after finally deciding that it would be too much of a hassle, I started at zero again. Then I came back to a thought I had days before, namely the thought that often, good ideas for games (mostly puzzle platformers) are those which are inspired by childrens’ fantasies. So I imagined a bit what a child could think, and being able to grab the moon with the fingertips and move it around just like that, well, that seemed like a good candidate. At this point, the theme was still in the back of my head, but I tried to ignore it mostly as it obviously would just hinder me to actually develop anything. I never was good in the “Theme” category, and for that I’m sorry, but I don’t think it’s the category I want to shine, really.

    I tried to create a Unity3D prototype out of that idea with the moon. Of course, prototypes become the real game eventually when doing a game jam, but first I wanted to see if I could actually create something like that. The main problem to begin with was the scale of the object currently grabbed, as it always has to be the same size for the player, no matter how far or near it would be away. I read something about the focal length of a camera before and I thought I had to factor this in in any case. I experimented (using some basecode I already announced in my “I’m in!” post) and searched on the internet, but it just wouldn’t work right. The object’s subjective size didn’t stay constant, and being very frustrated, I stopped after a while.

    Thus, I re-evaluated the idea of the four bandits. This one would follow the theme and I’d really like being able to control a group of (evil) adventurers – in first person perspective! In order to make it easier for myself, I started programming the movement (again in Unity3D), which would be along the cardinal directions only and also on a grid. Just like those age old games you might know, “Dungeon Master”, “Eye of the Beholder” or “Legend of Grimrock”. In the end, the movement worked somehow, and you could add NPCs to your party, and press a button to see all four viewports at once. Probably I could have made a more or less full game out of it, but at this point I didn’t see how I could add “fun” easily and I stopped yet again.

    prototype 2second prototype, no fun

    With the thought of fun being the most important part of it and without really expecting any results for this Ludum Dare anymore, I got back to the first prototype, and suddenly, the old problem was gone. Thinking about the focal length was a dead-end, and just getting rid of it was the way to get it work. The only problem now was the collision detection of an object that would get bigger the further it goes. Using Unity3D’s SphereCast() was the wrong direction, because the size of the collision sphere would be always the same. So now CheckSphere() gets called with a gradually increasing size of the radius parameter, and it does that a lot of times every frame – because of the simple nature of the rest of the game, this was possible without any noticable performance hits (at least on my computer). Of course, this means that every object basically has an additional bounding sphere, and that’s why most objects sometimes don’t behave as expected, especially those which don’t have uniform dimensions.

    prototype 1first prototype, working

    I uploaded the first prototype of the game – just a simple demonstration of the gameplay – late in the night, and those who actually started it and “got it”, said it could be awesome. Yay, motivation! Also, I earned myself some sleep. The next day I “only” had to make levels and fix any occuring bug. Also, story. Also, sound. Also, …

    I planned five levels at the beginning, and because of some very sad events before Ludum Dare, I didn’t think about it too long when I realized that I wouldn’t have time for all of them – as one of the levels would had have a kindergarten setting. So, three levels were made (in 3dsmax), and they describe how the protagonist is a kid with just an overly active imagination, and how this leads to an unfortunate outcome. I didn’t have time for more, and the ones I made aren’t really balanced/tested, so I am sorry for that. On the other side I am just relieved that the main gameplay works and can maybe be the foundation of a cool game; the Ludum Dare version of the finally named game “Tale of Scale” is mainly a sandbox game which happens to have a subtly communicated goal in each level.

    2the end result: Tale of Scale

    A short summarization of What-Went-Bad:

    • The start, or rather the theme. Either it is the start of a game for me, or it just stands in my way. Harumph. I squeezed the theme into the final game, but as most people won’t play it through, they probably will wonder where it actually is. I got a bit inspired by the movie “Looper”.
    • I still can’t make music. I tried composing some once or twice before, but I’m always embarrassed by my own efforts, so I don’t ever get over a certain point.
    • I don’t have a cool base code which actually would free me of the burden to do some stupid and boring stuff again and again. At least that’s a learning and can be helped … some day.

    And What-Went-Good?

    • The idea was cool enough to let people ignore the crude levels and graphics, hehe.
    • I actually managed to make three levels, even in the timeframe I wanted to make them. Seems like I finally get the hang on estimating such things, and this is one of the things a game jam really can help with.
    • I made most of the sounds myself with a microphone, and they sound okay enough. Nice.

    That’s it! Thanks for reading, and don’t forget to play the game (here’s the entry page) – or at least watch this gameplay video:

    I finished my entry even though there were times this weekend where I thought I would give up completely. The theme didn’t give me the right ideas, so I did something else and kind off added the theme (I think it still fits). Nonetheless, have fun playing Tale of Scale!

    I will participate too. I will be excited. I will use a programming language, an IDE, perhaps an editor, some art tools, and maybe sound software. I will program. I will draw. I might make 3D stuff. I will sit on a chair, I will have a computer with monitors, keyboard, mouse. I will eat food and drink liquids. I will sleep some hours, and poop. I will have an idea and create a game. I will finish it, and upload it.

    [edit]I could use this little “framework”, which is based on the stuff I made for LD23. It’s mainly a simple character controller for Unity3D, which doesn’t work perfect, but well enough for simple needs.[/edit]

    Some neat online tools for game developers

    Tuesday, October 23rd, 2012 10:45 am


    I recently made a (still very short) list of useful/interesting/neat online tools people recommended via Twitter, Facebook and – of course – Ludum Dare. The tools are suited for game designers, programmers and artists – and most of them can help in 48h game jams. They are all free.

    The list is here. If you have any more/better recommendations, I’d be happy to add them. :)
