  • Is there an alternative to SDL 1.3 for a C++ game that should run on iOS and Android?

    - by futlib
    I've used SDL for many desktop games, always as the cross-platform glue for: Creating a window Processing input Rendering images Rendering fonts Playing sounds/music It has never disappointed me at those tasks. But when it comes to graphics, I prefer to work with the OpenGL API directly, even though all of our games are 2D. In the project I'm currently working on, I've made sure to only use the API subset supported by both OpenGL 1.3 and OpenGL 1.0, so making the thing run on Android should be easy, I thought. Turns out there is no official Android or iOS port of SDL yet. However, there's one in SDL 1.3, which is still in development. SDL 1.3 doesn't seem very appealing to me for three reasons: It's been in development for at least 4 years, and I have no idea when it will be done, not to mention stable. It's not ported to as many platforms as SDL 1.2. From what I've seen, it uses OpenGL for drawing, so I suppose the community will move away from directly using OpenGL. So I'm wondering if I should use a different library for our current project - it doesn't matter much if I need to port my existing code from SDL 1.2 to SDL 1.3 or to some other library. We're planning to release on Windows, Mac OS X, Linux, iOS and Android, so good support for these platforms is essential. Is there anything stable that does what I want?

  • Leveraging Code Across Platforms in Ever Bigger Games

    - by ashes999
    Summary: The same way that I continually build complex engines and libraries within a single platform and technology to allow me to build increasingly bigger and better games, how to continue this when development crosses into different platforms? If I switch platforms, how do I leverage past code and experiences? Games are hard to build. Big games are even harder to build. I've decided that to be able to make big games, I need to start building smaller games, and building up an asset base of code, assets (graphics, sounds), tools, and most importantly, game engines, so that I can eventually get there. One game at a time. Let me give an analogy. To build an MMO 3D RPG, I would approach this by building and releasing small games with increasingly more features. This could entail, for example: A simple 2D game A tile-based game A game with RPG elements (items, equipment, monsters, battle) A full-fledged RPG A 3D RPG The problem now is if I have to change platforms or tools, I don't know how to leverage past code-bases (and experience) to start with a mature product. Right now, I'm writing Silverlight (FlatRedBall) games. Let's say I stick with this for ten years, and then suddenly decide to write a PS6 game, which is in a different programming language entirely. Granted, I have ten years of game-development experience (and correspondingly ten years of professional software development experience from my day job) to back me up. But I would still like some way to transplant that 2D RPG engine into the new programming language, or else leverage it somehow. Is this even possible? What are my options?

  • How to improve Minecraft-esque voxel world performance?

    - by SomeXnaChump
    After playing Minecraft I marveled a bit at its large worlds but at the same time I found them extremely slow to navigate, even with a quad core and meaty graphics card. Now I assume Minecraft is fairly slow because: A) It's written in Java, and as most of the spatial partitioning and memory management activities happen in there, it would naturally be slower than a native C++ version. B) It doesn't partition its world very well. I could be wrong on both assumptions; however it got me thinking about the best way to manage large voxel worlds. As it is a true 3D world, where a block can exist in any part of the world, it is basically a big 3D array [x][y][z], where each block in the world has a type (i.e BlockType.Empty = 0, BlockType.Dirt = 1 etc.) Now, I am assuming to make this sort of world perform well you would need to: A) Use a tree of some variety (oct/kd/bsp) to split all the cubes out; it seems like an oct/kd would be the better option as you can just partition on a per cube level not a per triangle level. B) Use some algorithm to work out which blocks can currently be seen, as blocks closer to the user could obfuscate the blocks behind, making it pointless to render them. C) Keep the block object themselves lightweight, so it is quick to add and remove them from the trees. I guess there is no right answer to this, but I would be interested to see peoples' opinions on the subject. How would you improve performance in a large voxel-based world?

  • Ubuntu 64bit Black Screen on Minecraft

    - by Signify
    I have tried posting on the forums, but I really need help (I'm a server admin and really don't want to have to switch to Windows just to run Minecraft). Anyhow, I originally was running openjdk6 as I was told that 7 was unstable and was getting periodical lag spikes while walking (at least once every 3 seconds the screen would freeze for a tenth of a second). After that, I attempted to install Sun's Java JDK7 (I couldn't get ahold of 6 without signing up for Oracle's newsletters). Upon attempting to run Minecraft, I got a black screen after logging in with this error message: 27 achievements 182 recipes Setting user: Thunder7102, -1618112820878091307 Exception in thread "Minecraft main thread" java.lang.UnsatisfiedLinkError: /home/noiro/.minecraft/bin/natives/liblwjgl.so: /home/noiro/.minecraft/bin/natives/liblwjgl.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch) at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary1(ClassLoader.java:1939) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1864) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1825) at java.lang.Runtime.load0(Runtime.java:792) at java.lang.System.load(System.java:1059) at org.lwjgl.Sys$1.run(Sys.java:69) at java.security.AccessController.doPrivileged(Native Method) at org.lwjgl.Sys.doLoadLibrary(Sys.java:65) at org.lwjgl.Sys.loadLibrary(Sys.java:81) at org.lwjgl.Sys.<clinit>(Sys.java:98) at org.lwjgl.opengl.Display.<clinit>(Display.java:132) at net.minecraft.client.Minecraft.a(SourceFile:184) at net.minecraft.client.Minecraft.run(SourceFile:657) at java.lang.Thread.run(Thread.java:722) Now, this got me fed up, so I tried to install a Windows 7 virtual machine through virtualbox, I gave it 256mb of graphics memory with 2D and 3D acceleration and 3GB of RAM. I installed Java JDK7 for Windows (which does work from experience on my other Windows 7 partition). Once again, a black screen after login. What the heck is going on guys?

  • Submitting software to a competition, it becomes their property?

    - by myrkos
    So I'm about to submit a game to a competition, but as I looked through the rules a chunk grabbed my attention: All Entries become the sole and exclusive property of Sponsor and will not be acknowledged or returned. Sponsor shall own all right, title and interest in and to each Entry, including without limitation all results and proceeds thereof and all elements or constituent parts of Entry (including without limitation the Mobile App, the Design Documents, the Video Trailer, the Playable and all illustrations, logos, mechanicals, renderings, characters, graphics, designs, layouts or other material therein) and all copyrights and renewals and extensions of copyrights therein and thereto. Without limitation of the foregoing, each Eligible Entrant shall and hereby does absolutely and irrevocably assign and transfer all of his or her right, title and interest in his or her Entry to Sponsor, and Sponsor shall have the right and may authorize others to use, copy, sublicense, transmit, modify, manipulate, publish, delete, reproduce, perform, distribute, display and otherwise exploit the Entry (and to create and exploit derivative works thereof) in any manner, including without limitation to embody the Entry, in whole or in part, in apps and other works of any kind or nature created, developed, published or distributed by Sponsor and to and register as a trademark in any country in Sponsor’s name any component of the Entry, without such Eligible Entrant reserving any rights or claims with respect thereto. Sponsor shall have the exclusive right, in perpetuity, throughout the Territory to change, adapt, modify, use, combine with other material and otherwise exploit the Entry in all media now known or hereafter devised and in any manner, in its sole and absolute discretion, without the need for any payment or credit to Entrant. So the game will become the sponsor's property; however, they don't ask for source code. So will I still own the rights to the source code, whatever that means? And if it doesn't win said competition, will I be able to publish it myself without their trademarks? I am very new to software legality stuff, so I would appreciate any clarification. Since there's a possibility I won't even own the source, is it possible to make the game core engine open source software with a not-very-restrictive license and include that in the project, so I at least still own the game engine? Or does it not work that way?

  • Oracle E-Business Suite is Helping to Save Lives at the National Marrow Donor Program

    - by Di Seghposs
    To improve the management of its life-saving operations, the National Marrow Donor Program recently modernized its financial and procurement operations by upgrading to Oracle E-Business Suite 12.1.   As the global leader in bone marrow and umbilical cord blood transplants, the NMDP manages a complex ecosystem of donor, patient, hospital, and biological data. “Maintaining accurate data and having an efficient matching process is essential, particularly as our global database of bone marrow patients grows and donor lists expand,” says Bruce Schmaltz, director of finance/controller. “We rely on the Oracle E-Business Suite to ensure our procurement and financial management processes meet the highest standards, enabling our growing non-profit to work swiftly and efficiently to help improve and save lives.” As the non-profit organization and its registry grew larger, NMDP needed a modern platform to store and integrate its financial information and complicated procurement process. It selected Oracle E-Business Suite for its ability to fit seamlessly into NMDP’s enterprise architecture. NMDP initially implemented Oracle E-Business Suite release 12 by leveraging Oracle Business Accelerators, which are rapid implementation tools and templates that help reduce implementation time and costs. With Oracle Financial Management and Oracle Procurement, NMDP has streamlined back-office processes and integrated its procure-to-pay business processes by leveraging industry leading accounts payable, accounts receivable, and general ledger modules. NMDP is currently rolling out Oracle Hyperion Performance Management applications and plans to implement Oracle Order Management and Oracle Advanced Pricing by the end of 2012. Read more details about NMDP’s modernization efforts.  For more updates on Oracle Financial Management Solutions, view our November 2012 Oracle Information InDepth Financial Management newsletter. Subscribe Now.

  • Why can't I compare two Texture2D's?

    - by Fiona
    I am trying to use an accessor, as it seems to me that that is the only way to accomplish what I want to do. Here is my code: Game1.cs public class GroundTexture { private Texture2D dirt; public Texture2D Dirt { get { return dirt; } set { dirt = value; } } } public class Main : Game { public static Texture2D texture = tile.Texture; GroundTexture groundTexture = new GroundTexture(); public static Texture2D dirt; protected override void LoadContent() { Tile tile = (Tile)currentLevel.GetTile(20, 20); dirt = Content.Load<Texture2D>("Dirt"); groundTexture.Dirt = dirt; Texture2D texture = tile.Texture; } protected override void Update(GameTime gameTime) { if (texture == groundTexture.Dirt) { player.TileCollision(groundBounds); } base.Update(gameTime); } } I removed irrelevant information from the LoadContent and Update functions. On the following line: if (texture == groundTexture.Dirt) I am getting the error Operator '==' cannot be applied to operands of type 'Microsoft.Xna.Framework.Graphics.Texture2D' and 'Game1.GroundTexture' Am I using the accessor correctly? And why do I get this error? "Dirt" is Texture2D, so they should be comparable. This using a few functions from a program called Realm Factory, which is a tile editor. The numbers "20, 20" are just a sample of the level I made below: tile.Texture returns the sprite, which here is the content item Dirt.png Thank you very much! (I posted this on the main Stackoverflow site, but after several days didn't get a response. Since it has to do mainly with Texture2D, I figured I'd ask here.)

  • Is it possible to keep nm-applet running between invocations of WM startup?

    - by serverninja
    I am using nm-applet to interface with NetworkManager, running xmonad as a window manager. My X sessions (including nm-applet) are set up with a /usr/local/bin/xmonad.start script. My question is, how can I keep nm-applet running in the background as long as X is running, but not necessarily xmonad? As mentioned above, it is being started with xmonad (and dying with it when xmonad is restarted, etc). I am using gdm to manage my X sessions, and I'm running 10.10. Where's a good place to start nm-applet to suit my particular needs? I need to remove it from the control of xmonad, but don't know where to start it otherwise. Any help, tips, etc appreciated. Edit: problem seems to be with how I have integrated xmonad. I have the session script as a file in /usr/share/xsessions/xmonad.desktop with the following contents: [Desktop Entry] Encoding=UTF-8 Name=XMonad Comment=Lightweight tiling window manager Exec=/usr/local/bin/xmonad.start Icon=xmonad.png Type=XSession /usr/local/bin/xmonad.start contains the following: #!/bin/bash xrdb -merge ~/.Xresources xcompmgr -c & trayer --edge top --align right --SetDockType true --SetPartialStrut true --expand true --width 8 --heighttype pixel --height 18 --transparent true --alpha 0 --tint 0x000000 & gnome-settings-daemon & gnome-screensaver & if [ -x /usr/bin/nm-applet ] ; then nm-applet --sm-disable & fi /usr/bin/urxvtd -q -o -f & eval `ssh-agent` & if [ -x /usr/bin/gnome-power-manager ] ; then sleep 1 gnome-power-manager & fi /usr/bin/gnome-volume-control-applet & exec xmonad The question is how do I integrate xmonad, gdm, X, etc in such a manner to replicate the behavior I currently have except with nm-applet (and possibly other programs) running whether or not xmonad is?

  • Added resolution not working after upgrading to 12.04

    - by David
    After upgrading, my screen resolution (added by xrandr comands on the start) did not work like before. Messages appear showing some errors (that i have never had in 11.10). "No se pudo aplicar la configuración almacenada para los monitores"/"Can't apply the stored configuration for the monitors." This script didn't work either. xrandr --newmode "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync xrandr --addmode VGA1 1280x1024_60.00 xrandr --output VGA1 --mode 1280x1024_60.00 I also tryed deleting monitors.xml but, nothing. This only erase the window message. It's been sayd that ##It's a normal buggy and well know problem for Pc's with Intel integrated video cards.## The new version of gnome-settings-daemon stores its configuration information in dconf rather than gconf. I tryed something, but the problem persist. This is what i did. Install the dconf-tools package, and then run dconf-editor. In the tree on the left, navigate org - gnome - settings-daemon - plugins - xrandr. Uncheck the active checkbox. restart your XServer (Ctrl+Alt+Backspace) (It didn't worked out for me, but it may be helpful to someone)

  • How to cover the widest range of computers when publishing?

    - by DevilWithin
    When you plan a game, or even when you already made a game, and its time to publish, you wonder how much of your audience is covered by the game technology demands. I'm directing this essentialy to casual games, as I constantly see people having old laptops and being unable to replace them. Laptops with integrated cards whose OpenGL version doesn't even support textures larger than 1024x1024. These people may be avid gamers as well, and a reasonable share of the audience to consider giving them the chance to play casual games, once they cannot play any blockbusters. As I've seen happening, a very "noticeable" example is Angry Birds. It's gameplay is merely casual (I think nobody disagrees here) and still, it uses so high resolution textures that at least OpenGL 2.0 or around is needed, which blocks away a lot of people. So, the actual question is: what is a good tradeoff for this issue? Would it be better to just sacrifice the texture resolution for everyone, but have more supported hardware? Would it be better to keep the high quality and just slice the textures into smaller ones, sacrificing the performance a little bit? What else? Any ideas about this topic are welcome for discussion.

  • 12.10 upgrade broke brightness keys [closed]

    - by Chris Morgan
    I have been running Ubuntu (64-bit) on my HP 6710b laptop (Core 2 Duo with integrated graphics) for several years, and the backlight brightness keys have always worked. Since I upgraded to Ubuntu 12.10 earlier today, those keys do not work any more. The secondary function keys: Fn+F3: sleep; still works (and considerably faster than ever before!) Fn+F8: battery info; still works Fn+F9: reduce brightness; stopped working in 12.10 Fn+F10: increase brightness; stopped working in 12.10 It may also be worth while mentioning that X does not appear to be receiving the brightness events at all, or at least not sending them out further. (This I detected with a key logger I wrote for a Uni project, which uses X's Record extension; it is informed of the sleep and battery info keystrokes, but doesn't receive the brightness ones at all.) In the mean time, I know that I can use the Brightness & Lock settings screen to alter the brightness. (Wow! I can suddenly make my backlight darker than I could before—I can go right down to turning the backlight off, something I couldn't do before... but this model has a fairly dim screen, so I don't expect to use that much, if ever.) How can I get the brightness keys working again? This question is probably strongly related to I can't control my Brightness in HP Compaq 6710s.

  • Disappearring instances of VertexPositionColor using MonoGame

    - by Rosko
    I am a complete beginner in graphics developing with XNA/Monogame. Started my own project using Monogame 3.0 for WinRT. I have this unexplainable issue that some of the vertices disappear while doing some updates on them. Basically, it is a game with balls who collide with the walls and with each other and in certain conditions they explode. When they explode they disappear. Here is a video demonstrating the issue. I used wireframes so that it is easier to see how vertices are missing. The perfect exploding balls are the ones which are result by user input with mouse clicking. Thanks for the help. The situations is: I draw user primitives with triangle strips using like this graphicsDevice.DrawUserPrimitives<VertexPositionColor>(PrimitiveType.TriangleStrip, circleVertices, 0, primitiveCount); All of the primitives are in the z-plane (z = 0), I thought that it is the culling in action. I tried setting the culling mode to none but it did not help. Here is the code responsible for the explosion private void Explode(GameTime gameTime, ref List<Circle> circles) { if (this.isExploding) { for (int i = 0; i < this.circleVertices.Length; i++) { if (this.circleVertices[i] != this.circleCenter) { if (Vector3.Distance(this.circleVertices[i].Position, this.circleCenter.Position) < this.explosionRadius * precisionCoefficient) { var explosionVector = this.circleVertices[i].Position - this.circleCenter.Position; explosionVector.Normalize(); explosionVector *= explosionSpeed; circleVertices[i].Position += explosionVector * (float)gameTime.ElapsedGameTime.TotalSeconds; } else { circles.Remove(this); } } } } } I'd be really greatful if anyone has suggestions about how to fix this issue.

  • Automatically revert to laptop screen when external monitor unplugged

    - by Ryan
    I regularly use an external monitor with my laptop, so when I use it, I usually have the laptop screen disabled when the monitor is connected, and this seems to cause problems when the monitor is disconnected. If the monitor is connected while the laptop screen is disabled, I can't get the X session to show up at all: I can Ctrl+Alt+F1 to open a terminal, and that works fine.. ..but Ctrl+Alt+F7 does nothing. The display is blank, and stays blank. The same thing happens whether I put the computer to sleep with the monitor connected, or if I disconnect while the computer is still awake. Rebooting the computer fixes the issue, as does killing Xorg and starting it again, but both of those are sub-optimal since I lose my current session. I'm currently using the open source graphics driver (xserver-xorg-video-ati). This question looks like it might answer my question, but unfortunately hwinfo is no longer available in the apt repository. Is there a way with current tools to automatically detect when the external monitor is disconnected and switch to the laptop display?

  • Windows 7 Phone Developer Tools CTP download

    - by mbcrump
    For those that don’t know, you can download the W7 Phone developer tools now. It is available here. I have installed it and wanted to share my experience so far. You can read the pre-release documentation here. First, here is what it comes with the install: The Windows Phone Developer Tools CTP includes the following: Visual Studio 2010 Express for Windows Phone CTP Windows Phone Emulator CTP Silverlight for Windows Phone CTP XNA 4.0 Game Studio CTP First impressions: No ISO image install (Bad for me because I use multiple machine and have to install from a bootstrapper. Its around 228mb download. I already have the VS2010 RC, but it still makes me install the VS2010 Express Edition. Windows Phone Emulator will only work with VS2010. No support for 05/08. Need at least a DX10 graphics compatible card. Final Word: (you are probably going to need this info) To start a new project, go to Installed Templates and select Silverlight for Windows Phone and Windows Phone Application. Use Silverlight for WPF style applications or XNA for W7 Games.

    I have HD 4850 card, Ubuntu 12.10 and installed legacy drivers using makson96 ppa. The issue is, that FGLRX can not detect my device and loads vesa bios. I had the same problem on ubuntu 11.10, 12.04 versions. I want to manually help fglrx find a matching device to load as it shoudld do. It is interesting, why does fglrx search for a device in a PCI:0@1:0:1 Bus? in xorg.cof different bus is indicated: Section "Device" Identifier "aticonfig-Device[0]-0" Driver "fglrx" BusID "PCI:1:0:0" EndSection fglrxinfo display: :0.0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc.

  • Ubuntu Server 11.10 boot, white terminal with garbled black text

    - by SpeedCrazy
    I just installed Ubuntu server 11.10 and the install went fine. This system is running on an Intel Pentium II board with onboard graphics. However when I try to boot into Ubuntu I get a white terminal with garbled black text. I have tried various grub 'fixes' as googling the issue seemed to suggest it was a res or grub related issue. I cannot ssh in so the issue does affect Linux as well. I have had no luck with anything thus far and am at my wits end. This was my first Ubuntu excursion as my friend told me it was better for servers than CentOS because it was easier... Not so much.... Does anyone have any ideas as to what the issue could be? When answering bear in mind I am an Ubuntu noob and Linux novice. As of 1/26/12 I have tried to add the console=ttyl line to the /etc/default/grub and run update-grub. This results in the line in the boot parameters that normally reads: linux /vmlunz-3.0.0-12-generic-pae root=/dev/mapper/dev-root rovt.handoff=7 now reads: linux /vmlunz-3.0.0-12-generic-pae root=/dev/mapper/dev-root ro console=ttyl vt.handoff=7 This does not work. Is there anyway to have console=ttyl inserted on a line by itself? I am at my wits ends, Thanks for all your help, Speed

  • A Quarter Century of SPARC

    - by kemer
    You might have missed an interesting milestone: the 25th anniversary of SPARC. Twenty-five years! Almost 40% of my life: humbling, maybe a little scary. When I joined Sun Microsystems in 1988, SPARC was just starting to shake things up. The next year we introduced the SPARCstation 1, which had basically triple the performance of our Motrolla-based Sun–3 systems. Not too long after that, our competition began a campaign of “SPARC is dead.” We really distressed them with our success, in spite of our small size. “It won’t last.” “It can’t last!” So they told themselves. For a stroll down memory lane take a look at this page. I remember the sales meeting we had in Atlanta to internally announce the SPARCstation 1. Sun hadn’t really hit the big times, yet. Our much bigger competitors viewed us as an ill-mannered pest, certain of our demise. And, why wouldn’t they be certain: other startups more our size, such as Apollo (remember them?), Silicon Graphics (they fought the good fight!), and the incredibly cool Symbolics are memories. Wait! There was also a BIG company, DEC, who scoffed at us: they are history, too. In fact, we really upset them with what was supposed to be an internal-only video production that was a take-off on Bruce Lee movies, in which we battled the evil Doctor DEC – complete with computer mice (or is that “mouses”?) wielded like nun chucks with the new SPARCstation 1 somehow in the middle of everything. The memory is vivid, but the details hazy. After all, that was almost a quarter century ago. So, here’s to Oracle’s SPARC: still going strong after all these years. – Kemer

  • Hidden Gems: Accelerating Oracle Data Integrator with SOA, Groovy, SDK, and XML

    - by Alex Kotopoulis
    On the last day of Oracle OpenWorld, we had a final advanced session on getting the most out of Oracle Data Integrator through the use of various advanced techniques. The primary way to improve your ODI processes is to choose the optimal knowledge modules for your load and take advantage of the optimized tools of your database, such as OracleDataPump and similar mechanisms in other databases. Knowledge modules also allow you to customize tasks, allowing you to codify best practices that are consistently applied by all integration developers. ODI SDK is another very powerful means to automate and speed up your integration development process. This allows you to automate Life Cycle Management, code comparison, repetitive code generation and change of your integration projects. The SDK is easily accessible through Java or scripting languages such as Groovy and Jython. Finally, all Oracle Data Integration products provide services that can be integrated into a larger Service Oriented Architecture. This moved data integration from an isolated environment into an agile part of a larger business process environment. All Oracle data integration products can play a part in thisracle GoldenGate can integrate into business event streams by processing JMS queues or publishing new events based on database transactions.
