    I’m in and C will be my weapon

    And that will be my graphics/input library of choice:asciiLib
    The game itself will be a crazy mix between Rogue and a few others I don’t tell you (at this moment). My primary goals will be:

    • Easy to understand – Maybe I’m simply stupid, but I never really understood the original Rogue mechanics, my game will provide you with easy-to-access helpful tutorials and pieces of advice on how to play this game
    • Skill-based gameplay – What I understood and what happens you in other games (like Pokemon / Final Fantasy) is that at some level in the fights, it isn’t you who is fighting, it is the computer fighting with itself, while the luck (or the random number generator) decides who will win. I’ll put up a fight system in which you can decide which one is going to win (meaning either you are good enough to beat your enemy or you are not).

    I wish you good luck and fun times making your game!

    Hey you (yes you out there),
    This will be my fourth LudumDare and hopefully my third game I actually release. Either way I’m sure It will be very fun :)
    Last time there were some problems with the execution of my games, whether on Windows (OpenAL) or on Linux (runtime libraries), but I worked a lot on the building process (and the code), updated my libraries, tested the base code so I’m happy to pronounce that this time there will be much fewer problems. The Windows application doesn’t depend on any OpenAL installation and for the Linux one you don’t have to download anything other than my actual game(except maybe OpenGL drivers which you should already have, if not… you need them! for many many games (not just mine)!), extract and you are ready to play (like you would do on Windows…). And here’s my inventory:

    • Language: C++
    • IDE:
      • On Windows: Visual Studio Express 2012 (Main development)
      • On Linux: CodeBlocks (Only for the Linux port)
      • On Macintosh: (Even though I have an old Macbook Air now, I didn’t have enough time to set up the IDE, install the libraries, etc.)
    • (Horrible) Sprites: Paint.NET
    • (Even more horrible) Music: Autotracker, Musagi, Aira Maestosa
    • Basecode: Yes
    • Coding libraries:
      • Input, Window/Time management: SDL2 (it’s out!)
      • Graphic: OpenGL
      • Sound: OpenAL
      • File libraries:
        • libpng
        • libogg, libvorbis
        • zlib

    Chameleon has his Linux port

    Hi,
    The first time I made something useful for Linux and it is even a game!
    So go get it, you sweet little Linux users!
    I know a few windows users had difficulties with this game, I uploaded a patched version, with the OpenAL runtime binaries directly within the archive instead of providing the official installer (lesson learned!), and no OpenGL extensions (like the lovely GL_EXT_framebuffer_object) are needed anymore.
    Would be nice if you could check out my game – Chameleon
    Have a happy judging
    Helco

    Hi, it’s me Helco and I finished my game “Chameleon”
    A little chameleon wakes up in a swamp, without memory about how he’s got there.
    Help him to his lovely lawn, kill monsters and eat flies.
    LD26_release_02

    A linux will come as soon as possible, but it’s night in germany and unfortunately I don’t have time to do this before the deadline.

    I hope you like it :)

    Day One – I’m in with “Chameleon”

    Hi,
    Even though minimalistic wasn’t my favorite theme, I found a nice idea for it and that is what I’m working no.
    I am pretty happy about still doing something for the game :)
    I interpreted the theme that way:

    • No fancy pictures, all the entities, particles, etc. have to be fully drawn by the program
    • The world is constructed out of many one-colored blocks, so here is no complexity either
    • No complex controls: You can go in four single directions and activate your… tongue
    • No complex story: As simple as possible and please don’t try to find realistic logic in it…

    But who wants to read text, here is the Screenshot you’re waiting for:
    LD26 Chameleon In-Dev

    And my ToDo-list:

    • Player movement: done
    • World functionality: done
    • Enemies: 3/4 done
    • Sound: nope
    • Gameplay content: nope
    • Polish, Menus and that stuff: nope

    But I hope I can do this stuff tomorrow but now: Good night!
    Helco

    I might be in….

    Hi,
    I have the time, I have the motivation but I don’t know if I’ll actually do something. This depends on the theme and if I can construct a game out of it. I really hope I can, as the last times I participated it was fun, even if I didn’t finished it for the competition.
    My potato arsenal:
    Coding: C++ (on Windows MSVC 2012, on Linux CodeBlocks with gcc)
    Libraries:

    • SDL – For creating the window, handle events and that stuff
    • OpenGL, GLee – For the graphics
    • libpng – For loading images
    • OpenAL – For the sound
    • libvorbis, libvorbisfile, libogg – For the sound files

    Basecode: Download I developed it the last two days and it should work on Windows and Linux
    Image editor:Paint.NET
    Map editor:DAME or Paint.NET
    Sound: sfxr, Autotracker and/or musagi

    I will try to make a Linux port as well, but there are two things about it:

    • Are they actually anybody out there who would try a Linux binary instead of a Windows one?
    • As I don’t know how to do static linking and dynamic linking with all correct settings, I will have to provide a list of runtime packages necessary for playing the game, as I don’t have enough time left to figure this out…

    I wish a merry Ludum Dare!

    ExecutionCode experimental script language – not a “I’m in”-Post

    Posted by
    Saturday, August 11th, 2012 11:44 am

    Hi, I like to introduce to you a new script language: ExecutionCode
    I didn’t inted to create a language for games, but of course it can be used for games. It’s inspired by normal assembly, but cutted down to just one parameter. Also there are huge changes to some other things. But look at your own at a small application (it counts to 10):

    //All commentars are done c-style
    /*so of course these multiline commentars
    are supported!*/

    /*
    programs are not splitted up in functions, okay basically they are,
    but I call them modules and all the functions imported from C++ have their own name :)
    */

    //a command is splitted up in group name and function name
    main {
    //those square brackets indicate variables
    system.alloc [counter]
    system.alloc [isNowEnd]
    //first I push a raw numeric value (here 1) on the param stack
    system.push 1
    /*then the system.set command pops that value from the param stack and copies it to the given
    variable.
    If you put something on the stack, the value! is on the stack so if a command wants to change
    a variable it has to require it as param*/
    system.set [counter]

    //this is a jump mark, because you have to implement your loops on your own
    LoopStart:
    //first I print the variable to the world
    console.println [counter]

    /*a mathematical operation is done by pushing the two values on the stack and give the
    target to the command
    */
    system.push [counter]
    system.push 1
    math.add [counter]

    //and now I want to if [counter] came to 10 so I use the logical.lesser command
    system.push [counter]
    //these brackets indicate a ressource
    system.push
    logical.equal [isNowEnd] //so if counter==11 then isNowEnd=1

    //and if isNowEnd==1
    system.skip [isNowEnd]
    system.jump “LoopStart”

    //don’t forget to free the variables
    system.free [counter]
    system.free [isNowEnd]
    }

    //a ressource can be like variables a number or a string
    //and here is another feature: if you put a ‘#’ in front of a number you can type hexadecimal
    //decimal, this is 11
    ressource #b

    The code might look irritating, if so, delete the commentars and try to understand just the actual code.
    The compiler/interpreter application is done in the meaning that this code can compiled in bytecode and this bytecode can be executed by the virtual machine in the same application, but it isn’t enough finished (particularly the error handling procedures), so it won’t be released now, but I hope I’ll get this done before next LudumDare. I’ll also write a full reference of this lanuage, the bytecode, the virtual machine and the compiler.
    If you have any questions about it just ask me.

    GrayWorld for MiniLD 36

    Sunday, July 15th, 2012 12:36 am

    My MiniLD 36 entry is finished!
    Okay not reaally finished, but I have to submit it…
    Actually there are three levels, which didn’t come into the game because I played too much minecraft and developed not enough on these…
    But here it is:

    The timer problem

    Posted by
    Saturday, April 28th, 2012 11:56 pm

    Hi,

    cause this problem was a bug in my LD game and will be a bug in other games I want to present it and possible solutions for it. I would like to know what you think about these or have another solution.

    The  bug

     Not all computers are as fast as other computers. That’s why a game without any timing limiter would execute on other computers faster or slower.

    Possible solutions

    There are some possible solutions I already know:

    • Limit the frame rate to a constant value (all procedural movement can be done with a constant value)
    • Compute the elapsed time between two frames (the elapsed time must be multiplied with all speed values)

    I want to show you my opinion about these.

    Limit the frame rate to a constant value

    It looks very easy you calculate the time span of the current frame and subtract it from the time span a full frame for the desired frame rate and you have the time you must wait before a new frame may start. But what is when you notice that your game is suddenly slow? The problem in the code can be thousand code lines before the code you were actually working on, but you don’t saw it because you can’t see when the frame takes more time. The frame rate, if you don’t have a very bad computer, stays at his value.

    Compute the elapsed time between two frames

    That is what I did all the time and it worked. But at that time I used the graphic functions of the SDL, but I switched to OpenGL because SDL was too slow (especially for large images). As I used SDL the max frame rate was about 500 and this was good enough for me. As I started Mr.No’s Laboratory I got 10.000 FPS and the timer function was broken. The reason is that I use milliseconds for computing the elapsed time. But at 10.000 FPS a frame only take 0.1 seconds but the function for getting the milliseconds returns an unsigned int (so there is no comma). The timing function works only with frame rates up to 1.000 frames per second (elapsed time=1)

    For ludum dare I already knew  this problem but I thought I solved it with computing the elapsed time every 50 frames (max frame rate=50.000). But I doesn’t work. Multiple people reported that the player is moving very fast. For a postmortem version I activate VSync (so the frame rate is about 60-75), but I want to keep my high frame rates. But what to do? I already know two solutions:

    • using nanoseconds instead of milliseconds
    • determine a proportion between the frames to skip (for the elapsed time calculation) and a performance of the computer (like cycles in one millisecond)

    using nanoseconds

    There is a easy-to-use function for java but for c++ I only know the functions for windows and even if I don’t port my applications to Linux or Mac I want to keep the possibility for it.+

    determine a proportion

    Using a code like: while (SDL_GetTicks()-ticksAtStart<100) count++; you get a performance value of your computer. Maybe there is a proportion between this value and the number of frames I must skip for a elapsed time value which I can use to do procedural movements.

     

    But whats your opinion about all these problems?

    Tools

    • ISO C++ (IDE: Microsoft Visual C++ 2008 Express) for programming.
    • Paint.NET for graphics
    • SXFR for sounds
    • Maybe Aira Maestosa for music

    Librarys:

    • SDL (for openGL loading, Input, stuff like that)
    • OpenGL
