  • Randomization of biomes

    - by user24527
    You know how in Minecraft, the World is ever-expanding and all the biomes are randomized? My generalized question is: In relation to a space simulation that is also ever-expanding as the player moves about the world, how would one go about programming this randomization in Java? My real question is: Could I get a simplified example broken down into these example classes: astroids (This would include how many astroids there are, their positioning in space, their size, how often the larger astroids occur, how close they are to each other, the limitations of how many of the large asteroids can be in one field, how often astroid fields are generated, etc.) star-types (size, color, type, how often they occur, where hey occur, etc.) inhabitable-planets (size, positioning, how often they're generated, where they are generated, etc.) This would be very helpful currently since I wish to make a simplified version of such a program.

  • how to design transparent screen in libgdx

    - by ved
    this question is for LibGdx geeks. I want to make transparent screen in my game. For example, when level completes I want a new transparent screen pop up and show player's high score, buttons to navigate on next level etc like in angry birds kind of screen. This type of screen can also use, when user click on pause button, to show pause screen. Please guide me to design this kind of screen. Or if I am going wrong to make transparent screens for this kind of situation. Please guide me for better one.

  • Slide decks of Windows Phone 7 talk @ MoMo

    - by subodhnpushpak
    Hi, I presented a talk on Windows Phone 7 @ MoMo and got awesome response, even though WP7 is quite new still. I also demoed 2 applications on both emulator and the actual device. It enjoy the look on audience faces when they see the app actually work on actual device. I see a great opportunity on WP7 and everyone I met agrees on the fact the WP7 has a very bright future ahead. The Ecosystem which WP7 has (developing/ debugging tools, emulator, almost flat learning curve,  office/sharepoint integration a lively forum, marketplace) makes it a major player in mobile, already. Here is the slide – deck. Here are the details of the event. http://momodelhi11.eventbrite.com/#m_1_100 And here are few snap shots of the event.

  • How to create reproducible probability in map generation?

    - by nickbadal
    So for my game, I'm using perlin noise to generate regions of my map (water/land, forest/grass) but I'd also like to create some probability based generation too. For instance: if(nextInt(10) > 2 && tile.adjacentTo(Type.WATER)) tile.setType(Type.SAND); This works fine, and is even reproduceable (based on a common seed) if the nextInt() calls are always in the same order. The issue is that in my game, the world is generated on demand, based on the player's location. This means, that if I explore the map differently, and the chunks of the map are generated in a different order, the randomness is no longer consistent. How can I get this sort of randomness to be consistent, independent of call order? Thanks in advance :)

  • Le H.264 est de retour sur Chrome, qui pourra lire les vidéos dans ce format grâce à une extension de Microsoft

    Le H.264 est de retour sur Chrome, qui pourra lire les vidéos dans ce format grâce à une extension de Microsoft Mise à jour du 03.02.2011 par Katleen Il y a un petit peu moins d'un mois, Google annonçait la fin du support du codec H.264 par son navigateur Chrome, ce qui en enchantait certains et en gênait d'autres. Aujourd'hui, une alternative est possible, grâce à Microsoft (qui s'était déjà occupé du problème sous Firefox). L'éditeur de Redmond vient ainsi de dévoiler son "Windows Media Player HTML5 Extension for Chrome", qui, comme son nom l'indique, est une extension pour Chrome qui permettra la lecture de vidéos au format H.264 par les utilisateurs du navigateur d...

  • 2D Physics in a networked game (iOS)?

    - by Pedro
    I am researching the possibilities for a new iOS game. It's going to be a run-n-gun type platformer, and I'm looking into the possibility of co-op multiplayer. The game itself wouldn't be very physics intensive, there will most likely be 20-30 physics bodies at any given time. For the multiplayer, I think I would have one player "hosting" and up to 3 other connecting via the Internet. Here's my first question, are there any 2D physics engines that work over a network(preferably open source)? My second question, Does anyone have any thoughts on using a non-networked engine (like Box2D or Chipmunk) and adding the networking component? Since there would not be very much information sent, do you think it would cause a lot of lag?

  • I cannot play some WMA files

    I did a backup of several music files from my older Windows XP system. Now I can play all the .MP3 files but not all the .WMA. There are some kinds of WMA files that can be reproduced without problems, may refute this in the picture below. The right file can be played, the left isn't. I have long been looking different sites, Q&A from here, installing many packages but not luck. An example is this answer. What can I do? My system: Ubuntu 11.10 32b. Player: Banshee & VLC

  • Determine how to display a tile based on surrounding tiles

    - by Jsmith
    I have a game engine which generates maps randomly, set on a 2d grid which is composed of 34px square graphical tiles. These tiles can be displayed in any of three ways, wall, corner, and floor(exists in 2 states, passable and impassible), and four directions, north, south, west and east. What I need to do is, based on the tiles around each individual tile, determine which state to display the tile in, e.g. north wall, northeast corner, floor so that when a player alters the map, the tiles around the affected tile adjust themselves to suit(i.e. tunneling). In case it becomes important, all gameobjects are inherited from the same class, whether they be players, NPC's, walls, or items.

  • How to give parallax backgrounds more depth

    - by user28015
    I have 3 tiled images of some sort of galaxy/space in the background of a 2D Game: The first one has an alpha of 100%, the second an alpha of 80% and the last one has an alpha of 60%. I scroll the the one in the background slower than the other ones of course. classic parallax. In the foreground I have some particles flying towards the player to simulate some dust / stars flying by. (I know that stars don't fly by, but I think we all have seen this in a lot of games). But I can't quite achieve the depth effect I am looking for. I want it to look "deeper". I did read something about using blending modes for the backgrounds, but that would require to render them as objects right? So the question is: What is a good technique to do a scrolling parallax background in GameMaker?

  • Inputting cheat codes - hidden keyboard input

    - by Fibericon
    Okay, here's what I want to do - when the player is at the main menu, I want them to be able to type in cheat codes. That's the only place I want it to work. I don't want to give them a text box to type into. Rather, I want them to simply type in a word (let's say "cheat", just for simplicity sake) that activates the cheat code. I only need to capture keyboard input when the window is in focus. What can I do to accomplish this?

  • Simple 2D Flight Physics with Box2D

    - by MarkPowell
    I'm trying to build a simple side scroller with an airplane being the player. As such, I want to build simple flight controls with simple but realistic-feeling physics. I'm making use of cocos2D and Box2D. I have a basic system working, but just can't get the physics feeling correct. I am applying force to the plane (which is a b2CircleShape) based on the user's input. So, basically, if the user pushes up, body_->ApplyForce(b2Vec2(10,30), body_->GetPosition()) is called. Similarly, for down -30 is used. This works and the plane flys along with up/down causing it to dive or climb. But it just doesn't feel right. There is no slowdown on climbs, nor speed up during dives. My simple solution is far to simple. How can I get a better feel for a plane climbing/diving? Thanks!

  • How do I get movies to work in my dual CD/DVD computer?

    - by user289178
    I have an older Dell Optiplex GX620. It has an IDE CD drive and an IDE DVD drive. I cannot seem to get Ubuntu 14.04 to allow movies to play. I've tried installing libdvdcss2 as well as the libdvdread4. VLC was installed last, but each time I attempt to play a movie, the player flashed briefly, then goes back to the initial screen like I didn't even have a DVD in the drive. I'm fairly new to the linux world, so any/all suggestions would be helpful.

  • Box2D random crash when adding joints

    - by user46624
    I'm currently working on a project which uses Box2D, when the player uses a certain key it should anchor to the ground. For that I use a weld joint, but when I add the joint the game will sometimes crash, it has a 1/10 change to crash. The error I recieve: Showing the controller Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 11 at org.jbox2d.dynamics.Island.add(Island.java:577) at org.jbox2d.dynamics.World.solve(World.java:1073) at org.jbox2d.dynamics.World.step(World.java:598) The code for adding the joints: WeldJointDef def = new WeldJointDef(); def.initialize(body, anchoredObject.body, body.getWorldCenter()); weldJoint = (WeldJoint) world.createJoint(def); I still get the error if I synchronize it

  • Weird keywords in google webmaster tools

    - by Argoron
    I just happened to check the keywords list on Google Webmaster Tools for my site, which is an educational content site about finance. To my big surprise, after the first keyword, which is 'finance', I found amongst the 20 highest ranked (!) entries words like: mysql, server, adobe, flash, player, homez. What (i'm tempted to add "the heck") does that mean ? Is that something I should worry about? If so, how did these get there and how can I eliminate these / avoid they get into that list ? Thanks very much in advance for your help

  • Character equipment combinations

    - by JimFing
    I'm developing a 2d isometric game (typical Tolkien RPG) and wondering how to handle character/equipment combinations. So for example, the player wears leather boots with chain-mail and a wooden shield and a sword - but then picks up plate-armour instead of chain-mail. I'm using Blender3D to create objects, environments and characters in 3D, then a script runs to render all 3D meshes into 2D orthographic tile maps. So I can use this script to create all the combinations of character equipment for me, but there would be an explosion in terms of the combinations required.

  • How can I imitate interaction and movement in Diablo II?

    - by user422318
    I'm prototyping a simple browser-based game. It's played from a top down perspective on a 2d canvas. You left-click on a point on the map, and your character will begin walking to it. If you click on a different point on the map, then your character will begin walking to the new point. It's similar to Diablo II: http://www.youtube.com/watch?v=EvDKt-To6K0&feature=related How can I best imitate this movement system for a player? Ideas... Track current coords and target coords If target coords are exactly up, left, right, or down, then increment appropriate direction until you get there Implied else: target coords are in a quadrant. To make this movement look natural, character will have to move diagonally. For example, pretend the target is to the northeast. For each game frame, alternate incrementing current coordinates in the north and then east directions.

  • Youtube showing horizontal lines when full screen in google chrome

    - by Blaze Tama
    First, im new in ubuntu so please bear with me. My google chrome shows strange behavior when playing youtube videos in full screen mode. There will be some horizontal white lines, which is exactly like when you playing the game without the vsync. I've checked firefox and the videos working perfectly in there. I also tried to play videos from my HDD using VLC player and its working fine. It seems the problem is in the google chrome alone. My version of ubuntu is 13.04, my laptop is asus n46vz and i use the latest release of google chrome. I've tried to ask google, but it seems he has no answer. Thanks for your time :D

  • How to divide hex grid evenly among n players?

    - by manabreak
    I'm making a simple hex-based game, and I want the map to be divided evenly among the players. The map is created randomly, and I want the players to have about equal amount of cells, with relatively small areas. For example, if there's four players and 80 cells in the map, each of the players would have about 20 cells (it doesn't have to be spot-on accurate). Also, each player should have no more than four adjacent cells. That is to say, when the map is generated, the biggest "chunks" cannot be more than four cells each. I know this is not always possible for two or three players (as this resembles the "coloring the map" problem), and I'm OK with doing other solutions for those (like creating maps that solve the problem instead). But, for four to eight players, how could I approach this problem? As always, any and all help is appreciated. :)

  • How can I protect my save data from casual hacking?

    - by Danran
    What options are there for saving game data in a secure manner? I'm interested in solutions specifically tailored for C++. I'm looking for something that is fast and easy to use. I'm only concerned about storing simple information such as Which levels are and are not unlocked The user's score for each level I'm curious again to know what's out there to use, any good libraries to use that give me nice, secure game data files that the average player can't mess with. I just found this here which looks very nice, but it would be great to get some opinions on potential other libraries/options out there.

  • Problem with Update(GameTime) Methods and Pause implementation

    - by Adam
    I have the pause function implemented and it works correctly in that it dims the player screen and stops updating the gameplay. The problem is that GameTime continues to increase while it is paused, so my method that checks gameTime versus previousSpawnTime before spawning another enemy gets messed up and if the game is paused too long it is noticeable that the next enemy draws far too early. Here is my code for the enemy update. private void UpdateEnemies(GameTime gameTime) { // Spawn a new enemy every 1.5 seconds if (gameTime.TotalGameTime - previousSpawnTime > enemySpawnTime) { previousSpawnTime = gameTime.TotalGameTime; // Add an Enemy AddEnemy(); } ... I also have other methods that depend on gameTime. I've tried getting the total pause time and subtracting that from the total game time, but I can't seem to get it to work correctly if that is the way I should go about solving this. If you need to see any other code let me know. Thank you.

  • Story and news-feed ideas for social network games

    - by arpine
    I am currently working on a educational and fun 2-in-1 game. As I am not a professional, I need advice on story and news-feed. The goal is simple-get richer, the story is about a worker who is trying to get over his/her financial problems and become rich. During the whole gaming process there is a news-feed (every day there are a couple of fresh news about what is going on). The news are fresh and individual so I need to write about 2000 pieces of news for 2 year gaming, maybe more. The problem is that I am not sure whether repetitive news can interest in this game. What can be done to make the news-making process easier but not boring from the point of view of the player?

  • Fast lighting with multple lights

    - by codymanix
    How can I implement fast lighting with multiple lights? I don't want to restrain the player, he can place an unlimited number and possibly overlapping (point) lights into the level. The problem is that shaders which contain dynamic loops which would be necessary to calculate the lighting tend to be very slow. I had the idea that if it could be possible at compiletime to compile a shader n times where n is the number of lights. If the number n is known at compiletime, the loops can be unrolled automatically. Is this possible to generate n versions of the same shader with just a different number of lights? At runtime I could then decide which shader to use for which part of the level.

  • Is Adobe Flash 11.2 working with Nvidia hardware again in 12.04?

    - by Oranges
    I installed the newest Nvidia-Linux drivers version number 304.43 on 12.04 installation and all Flash Videos now show me "accelerated video rendering". Previous Nvidia drivers + Adobe Flash only rendered in software, at least since Adobe officially said they turned off "hardware acceleration" for Linux, because of unstable and unsecure drivers. Has this changed? Is hardware acceleration really back? Can anyone verify this as well? The Nvidia driver 304.43 patch notes said: Fixed a bug that caused VDPAU to hang when expanding the YouTube Flash Player. Hardware: Nvidia 8600M GT
