  • What''s easy extensible technique to store game data?

    - by Miro
    I'm looking for library/technique for storing my game resources - levels, object (effects,world info), items(price,effects,...), NPC(visual info, behavior), everything except graphics/audio stuff. I've seen lua used for Awesome WM configuration. protobuf looks good, but it seems to be designed for network communication. I've tried to write my own parser, but as the project grows it's more and more harder to manage it and catch all the bugs. My requiremets: stability easy extension of data without need to convert older versions to newer good(don't have to be the best) performance of loading not much coding not XML!

  • Where to start in creating a massive multiplayer 3D Java game [on hold]

    - by user1373771
    I am planning on creating a massive multiplayer world and I am wondering where to start. I am quite inexperienced in the field of Java but I have researched into it and learned that it is perhaps my best bet in creating this project is Java for the fact that it has a much easier learning curve than C++ to beginners and still capable of holding massive amounts of players at a time. My question is simple: Should I start the game by creating a single player prototype and introducing multiplayer later as I become more experienced or start with multiplayer before I am completely experienced in the field. Thanks for your help!

  • 2D platformer gravity physics with slow-motion

    - by DD
    Hi all, I fine tuned my 2d platformer physics and when I added slow-motion I realized that it is messed up. The problem I have is that for some reason the physics still depends on framerate. So when I scale down time elapsed, every force is scaled down as well. So the jump force is scaled down, meaning in slow-motion, character jumps vertically smaller height and gravity force is scaled down as well so the character goes further in the air without falling. I'm sending update function in hopes that someone can help me out here (I separated vertical (jump, gravity) and walking (arbitrary walking direction on a platform - platforms can be of any angle) vectors): characterUpdate:(float)dt { //Compute walking velocity walkingAcceleration = direction of platform * walking acceleration constant * dt; initialWalkingVelocity = walkingVelocity; if( isWalking ) { if( !isJumping ) walkingVelocity = walkingVelocity + walkingAcceleration; else walkingVelocity = walkingVelocity + Vector( walking acceleration constant * dt, 0 ); } // Compute jump/fall velocity if( !isOnPlatform ) { initialVerticalVelocity = verticalVelocity; verticalVelocity = verticalVelocity + verticalAcceleration * dt; } // Add walking velocity position = position + ( walkingVelocity + initialWalkingVelocity ) * 0.5 * dt; //Add jump/fall velocity if not on a platform if( !isOnPlatform ) position = position + ( verticalVelocity + initialVerticalVelocity ) * 0.5 * dt; verticalAcceleration.y = Gravity * dt; }

  • best programming language for a web based game?

    - by Adam Geisweit
    what programming language would be best for making a web based game to be played in a browser, and where would i be able to find tutorials on how to use the language? i have looked up silverlight in xna (because that was what i was most fluent with), but it made my projects unusable for a month until i got all of silverlight off my computer. i have looked at java and javascript, but i have found no suitable places where i can learn to create games on either of these, just the basics of the language. does anyone have any advice on this?

  • Cocos2d: carom like game

    - by Raj
    Now I am working on carrom like game using cocos2d+Box2d. I set world gravity(0,0), want gravity in z - axis. I set following value for coin striker body: Coin body: density = 20.0f; friction = 0.4f; restitution = 0.6f; Shape Circle with radius - 15/PTM_RATIO Striker body: density = 25.0f; friction = 0.6f; restitution = 0.3f; Shape Circle with radius - 15/PTM_RATIO Output is not smooth, when I apply ApplyLinearImpulse(force,position); Coin movement looks like floating in air....takes too much time to stop... Which value of coin and striker makes it look like real carom?

  • How to use music in a simple game?

    - by Aerovistae
    It's like this: I've got this very simple game in mind, and I happen to be lucky enough to know this guy at my college who is the best musician I've ever met in person who wasn't already on a stage. He writes these beautiful songs on piano, just meandering and mysterious. They'd add so much as background music. But here's my dilemma: say I record a 5 minute long song from him. How do I use it? Do I set it playing, and then make it start over as soon as it ends? Do I leave a 5 minute period of silence and then start it over again? Or do I find other music and just have continuous music playing? What do other people usually do for this sort of thing?

  • Is there any kind of established architecture for browser based MMO games?

    - by black_puppydog
    I am beginning the development of a broser based game in which players take certain actions at any point in time. Big parts of gameplay will be happening in real life and just have to be entered into the system. I believe a good kind of comparison might be a platform for managing fantasy football, although I have virtually no experience playing that, so please correct me if I am mistaken here. The point is that some events happen in the program (i.e. on the server, out of reach for the players) like pulling new results from some datasource, starting of a new round by a game master and such. Other events happen in real life (two players closing a deal on the transfer of some team member or whatnot - again: have never played fantasy football) and have to be entered into the system. The first part is pretty easy since the game masters will be "staff" and thus can be trusted to a certain degree to not mess with the system. But the second part bothers me quite a lot, especially since the actions may involve multiple steps and interactions with different players, like registering a deal with the system that then has to be approved by the other party or denied and passed on to a game master to decide. I would of course like to separate the game logic as far as possible from the presentation and basic form validation but am unsure how to do this in a clean fashion. Of course I could (and will) put some effort into making my own architectural decisions and prototype different ideas. But I am bound to make some stupid mistakes at some point, so I would like to avoid some of that by getting a little "book smart" beforehand. So the question is: Is there any kind of architectural works that I can read up on? Papers, blogs, maybe design documents or even source code? Writing this down this seems more like a business application with business rules, workflows and such... Any good entry points for that?

  • Game getting progressively laggier?

    - by Valentin Krummenacher
    I have a small game in HTML5 that uses socket.io to communicate with a node.js server. Now my problem is that, eversince I did my last update on it it seems to have something "chunk up" in the background making it laggier and laggier the longer it runs. In the update were a few temporary local variables being defined with var(you know, variables that are only used during one function and then not needed anymore) alongside with alot of other changes, and I am not even sure if this update or something else is causing this. Might the "var" have caused it? Or what other reasons might this strange complication have?

  • How to implement time traveling into a game?

    - by Billy
    I was wondering how to implement time travel into a game. Nothing super complex, just time-reversal like what's in Braid, where the user can rewind/fast forward time by 30 seconds or whatever. I searched around the web a lot, but my results usually referred to using time as in like "it's 3:00" or a timer and such. The only thing I could think of was using 2 arrays, one for the player's x position and the other for the player's y position, and then iterating through those arrays and placing the character at that position as they rewind/fast forward time. Could that work? If it would work, how large would the array have to be and how often should I store the player's x and y? If it doesn't work, what else could I try? Thanks in advance!

  • Putting a Java/Slick game on your website?

    - by MakesYouStranger
    I've made a simple little 2D game in Java using Slick and I want to embed it in my website. I'm just a little confused as to how to go about it, I'm guessing I need to export it as a WAR file? Sorry if this isn't really specific but oddly enough I couldn't find any information on this subject. I think I may lack the basic vernacular to describe my question, because most of my google and other searches turn up completely unrelated results any help would be appreciated, I just need a starting point. Thanks

  • Drawing map tiles for iPhone game

    - by user17778
    I'm working on a turn-based strategy game for the iPhone that has a hexagon-grid based map in it. I'm in the process of drawing up the actual tiles for the different landscapes (i.e. forest, grassland, etc.) and was wondering what program to draw the tile images in. I would assume Adobe Illustrator since a vector-based image may allow for smooth images even when the user is zoomed in really close. Is this right? Thanks!

  • How to add reflection definition to read JSON files in web game

    - by user3728735
    I have a game which I deployed for desktop and Android. I can read JSON data and create my levels, but when it comes to reading JSON files from web app, I get an error that logs, "cannot read the json file". I researched a lot and I found out that I should add my JSON config class to configurations, so I added this line to gameName.gwt.xml, which is in core folder: <extend-configuration-property name="gdx.reflect.include" value="com.las.get.level.LevelConfig"/> But it did not work out. I have no idea where should I place this line or where I should change to make my web app work, so I can read JSON files.

  • Game Server on Windows Azure

    - by MrWiggels
    What do you guys think of using Windows Azure for deploying a custom built game server. It's being built in C#, and I want to get a few things down before stretching too far into the project. I like the idea of being scalable, but I also know that I will never get to the scale of anything to the scale of WOW, or something quite as big. It will just be an interesting journey to test something like this. So, will Windows Azure work for that, or is there any other services that can provide something like that?

  • Is there a repository of game logic algorithms?

    - by New2This
    I'm writing my first 2D game, and I'm writing some tracking logic for the computer enemies. Basic follow-the-player tracking was easy, but ineffectual. Too easy to escape. So I'm trying to implement some more sophisticated flanking and other tactics, and (as expected) it's pretty tricky. This is a topic I know nothing about. I'm going to keep trying, but it'd be awesome to have some examples or tips to work off of. Is there any place that has a decent set of pseudocode AI algorithms, or tips or advice on the subject, e.g. for 2D tracking?

  • Android game scrolling background

    - by Stevanicus
    Hi There, I'm just trying to figure out the best approach for running a scolling background on an android device. The method I have so far.... its pretty laggy. I use threads, which I believe is not the best bet for android platforms @Override public void run() { // Game Loop while(runningThread){ //Scroll background down bgY += 1; try { this.postInvalidate(); t.sleep(10); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } } where postinvalidate in the onDraw function simply pushings the background image down canvas.drawBitmap(backgroundImage, bgX, bgY, null); Thanks in advance

  • Relative Positions Of Player And Enemy Are Different In XNA 3D Game

    - by CoOlDud3
    I am having a problem in my 3D Jet Fighter Game using XNA. I have a Player Jet and a few enemy drones built from a separate class. The problem is that when I set Player position and a drone's position to a height 10f in y direction. They aren't at the same height. But if i move Drone's Position up 500f in the y direction then it is pretty much close to the player. Relatively They are supposedly at the same height but with different position values. Can Any One Help Please?

  • Empty Synchronized method in game loop

    - by Shijima
    I am studying the gameloop used in Replica Island to understand a bit about Android game development. The main loop has the below logic... GameThread.java (note the variable names in sample code dont match exact source code) while (!finished) { if (objectManager != null) { renderer.waitDrawingComplete(); //Do more gameloop stuff after drawing is complete... } } I was curious to see what waitDrawingComplete actually does, but found its just an empty syncrhonized method! I guess it does nothing, am I missing something here? GameRenderer.java line 328 public synchronized void waitDrawingComplete() { } Source code can be checked out here with SVN if you feel like having a look: https://code.google.com/p/replicaisland/source/checkout

  • Game Asset Size Over Time

    - by jterrace
    The size (in bytes) of games have been growing over time. There are probably many factors contributing to this: trailer/cut scene videos being bundled with the game, more and higher-quality audio, multiple levels of detail being used, etc. What I'd really like to know is how the size of 3D models and textures that games ship with have changed over time. For example, if one were to look at the size of meshes and textures for Quake I (1996), Quake II (1997), Quake III: Arena (1999), Quake 4 (2005), and Enemy Territory: Quake Wars (2007), I'd imagine a steady increase in file size. Does anyone know of a data source for numbers like this?

  • Is there any map maker for javaME game?

    - by user1494517
    For the past two weeks I was trying to make a map maker for my java ME 2D RPG game. I failed because i get errors using slick TWL and the forum for this is inactive. So I just wondered is there anyone that knows slick TWL (Themable Widget Library)? Or maybe do you know a good MapMaker where i could upload my map elements build a map and get numbers to use them for building map with LayerManager class? Already found one http://sourceforge.net/projects/tilemapeditor2d/. But the thing is my map elements are in different .png images. In one of those images there is 16 elements (trees water and etc) and those kind of images are 29. So it would be hard to build a map with LayerManager Well I was thinking putting everything into one image and that way it would be simplier.

  • Browser game in JSP? [closed]

    - by Constant
    I want to develop a browser-game (like ogame, travian) and I have some doubts in which technologies should I use. I was thinking in a server-side in JSP,Java and a client-side in HTML (or HTML5 if I learn to give it good use). Do you think my choices are right? I would like to make a board where many players could move simultaneously between tiles or squares. Do you think is possible in JSP or I should start with other language? Any suggestion aprecciated, and apologies for my english. Thank you! Regards!
