  • Minecraft: Slow performance OUT of the game

    - by blackn1ght
    I downloaded Minecraft yesterday to see what the fuss is about, brilliant game! When playing in Windowed mode, if I try and do anything else, i.e. use the computer, when the game is paused, the computer is incredibly slow, it takes a minute just to type a short message into empathy. Also, once I quit the game, the computer remains slow for about 5 minutes, until it magically frees up and becomes fast again. Could this be related to the 512mb RAM limitation of Java, and the machine is swapping? Even trying to submit this post is incredibly slow and frustrating, it's taking me a minute just to click in the 'Tag's box. Any ideas? Ubuntu 10.10 x64 Intel Q9550 4GB RAM nVidia 8800GTS 320mb (w/prop drivers installed)

  • How can I cleanly and elegantly handle data and dependancies between classes

    - by Neophyte
    I'm working on 2d topdown game in SFML 2, and need to find an elegant way in which everything will work and fit together. Allow me to explain. I have a number of classes that inherit from an abstract base that provides a draw method and an update method to all the classes. In the game loop, I call update and then draw on each class, I imagine this is a pretty common approach. I have classes for tiles, collisions, the player and a resource manager that contains all the tiles/images/textures. Due to the way input works in SFML I decided to have each class handle input (if required) in its update call. Up until now I have been passing in dependencies as needed, for example, in the player class when a movement key is pressed, I call a method on the collision class to check if the position the player wants to move to will be a collision, and only move the player if there is no collision. This works fine for the most part, but I believe it can be done better, I'm just not sure how. I now have more complex things I need to implement, eg: a player is able to walk up to an object on the ground, press a key to pick it up/loot it and it will then show up in inventory. This means that a few things need to happen: Check if the player is in range of a lootable item on keypress, else do not proceed. Find the item. Update the sprite texture on the item from its default texture to a "looted" texture. Update the collision for the item: it might have changed shape or been removed completely. Inventory needs to be updated with the added item. How do I make everything communicate? With my current system I will end up with my classes going out of scope, and method calls to each other all over the place. I could tie up all the classes in one big manager and give each one a reference to the parent manager class, but this seems only slightly better. Any help/advice would be greatly appreciated! If anything is unclear, I'm happy to expand on things.

  • How do you prevent inflation in a virtual economy?

    - by Tetrad
    With your typical MMORPG, players can usually farm the world for raw materials essentially forever. Monsters/mineral veins/etc are usually on some sort of respawn timer, so other than time there really isn't a good way to limit the amount of new currency entering the system. That really only leaves money sinks to try to take money out of the system. What are some strategies to prevent inflation of the in-game currency?

  • android multitouch problem

    - by Max
    Im aware that there a a couple of posts on this matter, but Ive tried all of them and none of them gets rid of my problem. Im starting to get close to the end of my game so I bought a cabel to try it on a real phone, and as I expected my multitouch dosnt work. I use 2 joysticks, one to move my character and one to change his direction so he can shoot while walking backwards etc. my local variable: public void update(MotionEvent event) { if (event == null && lastEvent == null) { return; } else if (event == null && lastEvent != null) { event = lastEvent; } else { lastEvent = event; } int index = event.getActionIndex(); int pointerId = event.getPointerId(index); statement for left Joystick: if (pointerId == 0 && event.getAction() == MotionEvent.ACTION_DOWN && (int) event.getX() > steeringxMesh - 50 && (int) event.getX() < steeringxMesh + 50 && (int) event.getY() > yMesh - 50 && (int) event.getY() < yMesh + 50) { dragging = true; } else if (event.getAction() == MotionEvent.ACTION_UP) { dragging = false; } if (dragging) { //code for moving my character statement for my right joystick: if (pointerId == 1 && event.getAction() == MotionEvent.ACTION_DOWN && (int) event.getX() > shootingxMesh - 50 && (int) event.getX() < shootingxMesh + 50 && (int) event.getY() > yMesh - 50 && (int) event.getY() < yMesh + 50) { shooting = true; } else if (event.getAction() == MotionEvent.ACTION_UP) { shooting = false; } if (shooting) { // code for aiming } This class is my main-Views onTouchListener and is called in a update-method that gets called in my game-loop, so its called every frame. Im really at a loss here, I've done a couple of tutorials and Ive tried all relevant solutions to similar posts. Can post entire Class if necessary but I think this is all the relevant code. Just hope someone can make some sence out of this.

  • Collision disturbing the jumping mechanic in java 2D game [on hold]

    - by user50931
    So I have been working on a 2D Java game recently and everything was going smoothly, until I reached a problem to do with the players jumping mechanic. So far I've got the player to jump a fixed rate and fall due to gravity. Hers my code for my Player class. public class Player extends GameObject { public Player(int x, int y, int width, int height, ObjectId id) { super(x, y, width, height, id); } @Override public void tick(ArrayList<GameObject> object) { if(go){ x+=vx; y+=vy; } if(vx <0){ facing =-1; }else if(vx >0) facing =1; checkCollision(object); checkStance(); } private void checkStance() { if(falling){ //gravity jumping = false; vy = speed/2; } if(jumping){ // Calculates how high jump should be vy = -speed*2; if(jumpY - y >= maxJumpHeight) falling =true; } } private void checkCollision(ArrayList<GameObject> object) { for(int i=0; i< object.size(); i++ ){ GameObject tempObject = object.get(i); if(tempObject.getId() == ObjectId.Ledge){ if(getBoundsTop().intersects(tempObject.getBoundsAll())){ //Top y = tempObject.getY() + tempObject.getBoundsAll().height; falling =true; } if(getBoundsRight().intersects(tempObject.getBoundsAll())){ // Right x = tempObject.getX() -width ; } if(getBoundsLeft().intersects(tempObject.getBoundsAll())){ //Left x = tempObject.getX() + tempObject.getWidth(); } if(getBoundsBottom().intersects(tempObject.getBoundsAll())){ //Bottom y = tempObject.getY() - height; falling =false; vy=0; }else{ falling =true; } } } } @Override public void render(Graphics g) { g.setColor(Color.BLACK); g.fillRect((int)x, (int)y, width, height); } @Override public Rectangle getBoundsAll() { return new Rectangle((int)x, (int)y,width,height); } public Rectangle getBoundsTop() { return new Rectangle((int) x , (int)y ,width,height/15); } public Rectangle getBoundsBottom() { return new Rectangle( (int)x , (int) y +height -(height /15),width,height/15); } public Rectangle getBoundsLeft() { return new Rectangle( (int) x , (int) y + height /10 ,width/8,height - (height /5)); } public Rectangle getBoundsRight() { return new Rectangle((int) x + width - (width/8) ,(int) y + height /10 ,width/8,height - height/5); } } My problem is when I add: else{ falling =true; } during the loop of the ArrayList to check collision, it stops the player from jumping and keeps him on the ground. I've tried to find a way around this but haven't had any luck. Any suggestions?

  • Basic Android game loop having issues

    - by WillDaBeast509
    I've set up a very basic game loop that should draw a circle, run 100 times, then draw another. I also have a text field that should display how many times the loop has ran. However, the screen seems to not update. It displays a different value for the tick count (different each time the app is ran) and simply stays there. After exiting the app, I get an error saying "Unfortunately, MyApp has stopped." Here is the relevant code: DrawView public class DrawView extends SurfaceView implements SurfaceHolder.Callback { Paint p = new Paint(); MainThread thread; private int y=0; public DrawView(Context c) { super(c); thread = new MainThread(this, getHolder()); thread.running = true; getHolder().addCallback(this); setFocusable(true); } public void draw(Canvas c) { if(c==null) return; //super.onDraw(c); c.drawColor(Color.WHITE); p.setColor(Color.RED); p.setTextSize(32); p.setTypeface(Typeface.SANS_SERIF); c.drawCircle(getWidth()/2-100,getHeight()/2, 50, p); c.drawText("y = " + y, 50, 50, p); if(y>=100) { Log.i("DRAW", "drawing circle"); c.drawCircle(getWidth()/2+100,getHeight()/2, 50, p); } else y++; Log.i("INFO", "y = " + y); } @Override public boolean onTouchEvent(MotionEvent event) { return true; } public void onDraw(Canvas c){} public void surfaceCreated(SurfaceHolder p1) { thread.start(); } public void surfaceChanged(SurfaceHolder p1, int p2, int p3, int p4) { // TODO: Implement this method } public void surfaceDestroyed(SurfaceHolder p1) { thread.running = false; boolean retry = true; while (retry) { try { thread.join(); retry = false; } catch (InterruptedException e) { Log.i("EX", "cathing exception"); } } } } MainThread public class MainThread extends Thread { private DrawView page; private SurfaceHolder holder; public boolean running; public MainThread(DrawView p, SurfaceHolder h) { super(); page = p; holder = h; } @Override public void run() { while(running) { Canvas c = holder.lockCanvas(); page.draw(c); holder.unlockCanvasAndPost(c); } } } Here is an example log outupt: http://pastebin.com/tM9dUPuk It counts the number of ticks correctly and should draw the second circle, but the screen looks like its not updating. After closing the app, the log continues to run and keep outputting "y = 100 drawing circle" until it crashes and shows the error report. What is going on and how can I fix these two problems?

  • What reference point/ tutorial could I use to help me make a "Ball rolling" game in flash?

    - by user1798964
    I am a complete newbie to programming, only took high school Computer science so I kind of know what im doing, I just want to know how I can make a ball rolling game that I want to make, could anyone show me an example of a good "ball rolling game" that has good physics and everything, I have tried to use Box2D for the physics portion of the game, but I found that using that is just code and I can't figure out how to make the graphics and details of the world I want to make in my game, all I would like to do would have a game that has the collision detection and physics of box2d only apply to one ball in it and use the left and right keys to move it. sorry if I am too unclear, if anyone could show a tutorial or something to me on how to make a proper "Ball rolling" game that has good physics that would be appreciated, thank you for taking the time to read this

  • How can I implement a matchmaker?

    - by csiz
    I'm making a multiplayer game, where players are separated in to rooms that would ideally have about 20 players. So I need a few pointers on an algorithm to distribute the players in to these rooms. A few more constraints: When a players gets in to a room, he should stay there until he decides to exit (the room itself changes levels) There may be more room servers, every server should create more rooms until near full capacity There's a central server that manages all the room servers, and directs the players towards their room

  • game programming career, vc++ reference and future of it [closed]

    - by Pappu Bacha
    1) I have quite a lot of interest in game programming and I (to my thought) am quite good at programming skills, I have developed some console based animations and text based animation games (like copter-it, snake, and a music visualization), should I invest in game programming? I have 2 years at college left. 2) If I am to pursue a career in game programming, and I select to go only with c++ and DirectX, is it enough? is assembly language necessary? 3) is Visual C++ or MFC dead? should I invest in it or not? 4) I am unable to find any reference book for Visual C++ 2008 or later (just like C++ the complete reference book) I need a book that covers the basic fundamentals and covers the most of the libraries etc.

  • How should game objects with fixed positions in the world be positioned?

    - by mars
    I have some game objects that are always at the same position in my game world as they make up some of the scenery of my puzzle game. At the moment, their positions are sort of hard coded in and some of their positions are calculated relative to the hard coded positions of other objects at the time of game initialization. This has been hard to maintain because whenever I've decided to change the position of these scenery objects as the game design evolved, I have to go and rewrite parts of the code that place the created objects and calculate their positions in the world. Is there a more maintainable way of handling the positioning of fixed game objects?

  • Want to make RTS strategy game, good starting point...?

    - by NOLANDI
    everybody! I find this community because I did research about game developing topics. So I decide to register on this community and ask for your opinion. I am not begineer in computer stuffs, and I know logic of programming language. I have little knowlegde of C, C++, Started to learn C#...but I was always oriented about other areas of IT. Amateur for game making but not in IT general! I am interested to make RTS strategy video game, isometric camera view (like PC GAME COMMANDOS for example)...so I started to read many books about DirectX, XNA, OpenGL, C#, AI programming...so I want to know where is good starting point for making this game genre. I want to use C# for this project, not C++, since I always had trouble with it, because it is too complicated. I see good oportunity for learning C#, since it has more object-oriented concept, with much less code and easy readible code for writing. Beside of that I know that C++ is the more powerful language until today. So I want to use DirectX and C# for my project. But it will required more time for sure, to learn it. I have trouble with finding books for c# & DirectX (I found just one), but in every next book, it is programming in c++! I read many web sites and they mentioned Slim DX, and in generaly, other articles which I read tells that it is possible to make good game with combination c# and directX, but...I don't have enough information about all this stuffs, so I became confused! It is really hard to have wish to learn c++ from scratch, since I started c# and I like it really...I don't try OpenGL, but I am already familiar with DirectX (some beginning stuffs), and I think that it is good and interesting. So, I decide to choose between maybe Unity3d and XNA first. XNA...hm, it sound that it is not bad solution, but I heard that it is already overcome technology, and I think that it is better to wait with XNA, until I try to make something with DirectX and C#, at first. But I dont know it is possible to make strategy game in XNA?! Maybe I am wrong. I also, find Unity 3D game engine and I find that I could programming there in C#, but many all examples are written in Javascript (Digital tutors videos)...But I generaly have wish to learn it too, because it allows to export games to mobile phones, there a lot of documentations, it is free, etc... I want to find best way to learn C# and DirectX, and make this game, but I dont know if it's possible to combine?! But maybe is good to first try Unity and XNA, because I am beginner?! Thank you all! I am willing to hear your expirience.

  • Java game applet development

    I'm getting 4 sec delay when sending objects over UDP. Working on small game and trying to implement multiplayer. For now just trying to synchronize movements of 2 balls on the screen.

  • Common Access Card (CAC) Authentication Using Java

    - by Paul
    I'm bascially looking for someplace to start learning how to interface with a government CAC card using java. Ultimately, my goal is to find out how to use CAC card authentication (by PIN number) to authorize access to a website hosted using a Tomcat/J2EE server. But I'll need somewhere to start. So I figure I'd start by writing a small java program to simply read the CAC card information from the CAC card which is inserted into a card reader on my keyboard (DELL keyboard with CAC reader above the numeric keypad). By searching google, I found the cacard java project (https://cacard.dev.java.net/) which was replaced by the OpenSSO project. But I can't seem to find sample code of how to use it to connect to a card, read from a card, etc. Does anyone know where I can find some sample code so that I can start learning how to interact with a CAC card using java? Thanks EDIT: After researching more, I was thinking, would I be able to just set clientAuth="true" in the connector element in the server.xml file? http://tomcat.apache.org/tomcat-6.0-doc/ssl-howto.html clientAuth: Set this value to true if you want Tomcat to require all SSL clients to present a client Certificate in order to use this socket.

  • ATI Radeon 5850 video card one analog, one digital and one tv connected to hdmi, unable to run all 3

    - by McLovin
    I have one analog monitor connected through dvi adapter one digital monitor connected through dvi tv connected through hdmi I'm unable to run all 3 at the same time, when I try to extend desktop it asks me to disable one of the monitors so I can only have 2 at one time. I tried finding solution but according to some forums I should be able to achieve it since one is analog I should be able to run 3 outputs with hdmi that way. Does any one have any suggestions? Thank you.

  • Can a PCI Graphics card, and AGP be used together?

    - by Everyone
    The question pretty much says it all. I use an old 845GBV board ( to-date reliant upon the integrated graphics processor ). All slots on the board are unused. Lately I've been thinking in terms changing it to a dual monitor so that I can use one console for documentation/help/sample code/whatever, the other one to play with code. Assuming this board can handle a PCI GPU, can an AGP4x board coexist with a PCI GPU?

  • This Year's SQL Christmas Card

    - by Mike C
    This year's Christmas Card is similar to last year's. I used the geometry data type again for a spatial data design. Just download the attachment, unzip the .SQL script and run it in SSMS. Then look at the Spatial Data preview tab for the result. Also don't forget to visit http://www.noradsanta.org/ if your kids want to track Santa. Merry Christmas, Happy Holidays and have a great new year!...(read more)

  • database design help for game / user levels / progress

    - by sprugman
    Sorry this got long and all prose-y. I'm creating my first truly gamified web app and could use some help thinking about how to structure the data. The Set-up Users need to accomplish tasks in each of several categories before they can move up a level. I've got my Users, Tasks, and Categories tables, and a UserTasks table which joins the three. ("User 3 has added Task 42 in Category 8. Now they've completed it.") That's all fine and working wonderfully. The Challenge I'm not sure of the best way to track the progress in the individual categories toward each level. The "business" rules are: You have to achieve a certain number of points in each category to move up. If you get the number of points needed in Cat 8, but still have other work to do to complete the level, any new Cat 8 points count toward your overall score, but don't "roll over" into the next level. The number of Categories is small (five currently) and unlikely to change often, but by no means absolutely fixed. The number of points needed to level-up will vary per level, probably by a formula, or perhaps a lookup table. So the challenge is to track each user's progress toward the next level in each category. I've thought of a few potential approaches: Possible Solutions Add a column to the users table for each category and reset them all to zero each time a user levels-up. Have a separate UserProgress table with a row for each category for each user and the number of points they have. (Basically a Many-to-Many version of #1.) Add a userLevel column to the UserTasks table and use that to derive their progress with some kind of SUM statement. Their current level will be a simple int in the User table. Pros & Cons (1) seems like by far the most straightforward, but it's also the least flexible. Perhaps I could use a naming convention based on the category ids to help overcome some of that. (With code like "select cats; for each cat, get the value from Users.progress_{cat.id}.") It's also the one where I lose the most data -- I won't know which points counted toward leveling up. I don't have a need in mind for that, so maybe I don't care about that. (2) seems complicated: every time I add or subtract a user or a category, I have to maintain the other table. I foresee synchronization challenges. (3) Is somewhere in between -- cleaner than #2, but less intuitive than #1. In order to find out where a user is, I'd have mildly complex SQL like: SELECT categoryId, SUM(points) from UserTasks WHERE userId={user.id} & countsTowardLevel={user.level} groupBy categoryId Hmm... that doesn't seem so bad. I think I'm talking myself into #3 here, but would love any input, advice or other ideas. P.S. Sorry for the cross-post. I wrote this up on SO and then remembered that there was a game dev-focused one. Curious to see if I get different answers one place than the other....
