• canvas tile grid, hover effects, single tilesheet, etc

  - by user121730

  I'm currently in the process of building both the client and server side of an html5, canvas, and WebSocket game. This is what I have thus far for the client: http://jsfiddle.net/dDmTf/7/ Current obstacles The hover effect has no idea what to put back after the mouse leaves. Currently it's just drawing a "void" tile, but I can't figure out how to redraw a single tile without redrawing the whole map. How would I go about storing multiple layers within the map variable? I was considering just using a multi-dimensional array for each layer (similar to what you see as the current array), and just iterating through it, but is that really an efficient way of doing it? Side note The tile sheet being used for the jsfiddle display is only for development. I'll be replacing it as things progress in the engine. I hope you can help! Hopefully you guys can help me, I've been struggling to get through things, since I'm learning how things kind of stuff works as I go. If you guys have any pointers for my JavaScript, feel free. As I'm more or less learning advanced usage as I go, I'm sure I'm doing plenty of things wrong. Note: I will continue to update this post as the engine improves, but updating the jsfiddle link and updating the obstacles list by striking things that have been solved, or adding additions. Thanks!

• 3D Texture Mapping (Atlas)

  - by Tim Hatch

  This is a pretty simple question. If I was to use multiple images in a single texture for a 3D cube, how would I go about re-using each vertex (having 8 total vs 24)? With a single buffer of 8 vertices, I don't see how I'd properly reuse the UV values. Any help on that? I know it's not terribly clear, but I figured it was a simple question. The 2D method is pretty easy, the next coordinates would be the same as the first (0,0 and 0,1 respectively). However, the above 3D version has me quite befuddled.

• Windows 7: How to prevent Windows from caching my desktop wallpaper

  - by rmartz

  I have a service running that renders a changing wallpaper every 5 minutes or so, and replaces the current image file with the new one automatically (That is to say, new image but same filename). On Linux, the change is detected almost automatically, and so I have the most current wallpaper. However, on my Windows 7 machine (Which syncs the image with my Linux machine over Dropbox), it appears to cache the wallpaper from the last time I manually set the wallpaper. The image never changes, even if I restart. Is there a way to make Windows detect the file change, or periodically refresh the wallpaper cache? I'd like to avoid third-party apps if at all possible.

• How can I pass an external instance to the constructor of an object that's being created using the default XNA XML content loader?

  - by Michael

  I'm trying to understand how to use the XNA XML content importer to instantiate non-trivial objects that are more than a collection of basic properties (e.g., a class that inherits from DrawableGameObject or GameObject and requires other things to be passed into its constructor). Is it possible to pass existing external instances (e.g., an instance of the current Game) to the constructor of an object that's being created using the default XNA XML content loader? For example, imagine that I have the following class, inheriting from DrawableGameComponent: public class Character : DrawableGameComponent { public string Name { get; set; } public Character(Game game) : base(game) { } public override void Update(GameTime gameTime) { } public override void Draw(GameTime gameTime) { } } If I had a simple class that did not need other parameters in its constructor (i.e., the Game instance), then I could simply use this XML: <XnaContent> <Asset Type="MyNamespace.Character"> <Name>John Doe</Name> </Asset> </XnaContent> ...and then create an instance of Character using this code: var character = Content.Load<Character>("MyXmlAssetName"); But that won't work because I need to pass the need to pass the Game into the constructor. What's the best way to handle this situation? Is there a way to pass in things like the current Game using the default XNA XML content loader? Do I need to write my own XML loader? (If so, how?) Is there a better object-oriented design that I should be using for my classes? Note: Although I used Game in this example, I'm really just asking how to pass any type of existing instance to my constructors. (For example, I'm using the Farseer Physics Engine, and some of my classes also need a reference to the Farseer World object too.) Thanks in advance.

• Working out of a vertex array for destrucible objects

  - by bobobobo

  I have diamond-shaped polygonal bullets. There are lots of them on the screen. I did not want to create a vertex array for each, so I packed them into a single vertex array and they're all drawn at once. | bullet1.xyz | bullet1.rgb | bullet2.xyz | bullet2.rgb This is great for performance.. there is struct Bullet { vector<Vector3f*> verts ; // pointers into the vertex buffer } ; This works fine, the bullets can move and do collision detection, all while having their data in one place. Except when a bullet "dies" Then you have to clear a slot, and pack all the bullets towards the beginning of the array. Is this a good approach to handling lots of low poly objects? How else would you do it?

• Java EE @ Devoxx UK

  - by delabassee

  Devoxx UK is taking place next week (12th and 13th June) in London. As with any Devoxx conference, this UK edition will have a nice mix of content, an impressive list of speakers and obviously Java EE will be well will covered too:  Apache TomEE, Java EE Web Profile and more on Tomcat (David Blevins) Myths, Tales and Voodoo - About Java EE and Testing (Adam Bien) 50 new features of Java EE 7 (Antonio Goncalves & Arun Gupta) Java EE 7 Hands-on Lab (Arun Gupta) In addition, there will be 2 BoF related to Java EE on Thursday evening, the first BoF will be about the Java EE platform and the second one will be about the Java EE Reference Implementation, i.e. GlassFish. I will participate in the Java EE Community BoF where will discuss Java EE general but with all recent activities, I suspect that a large portion of the BoF will spent on discussing the current plans for Java EE 8.  Right after and in the same room, I will join Steve Millidge of C2B2 for the GlassFish is here to stay! BoF. The goal is to discuss on GlassFish, the current status, the plans for the next release, how the community can contributes, etc. It should be mentioned that attending those BoFs is completely free, just make sure to register here.  So if you are in London next week, mind the Geek and see you at Devoxx UK!

• Diff 2 files while ignoring parts of lines

  - by Millianz

  I would like to diff a file system. Currently my bash script prints out the file system recursively into a file (ls -l -R) and diffs it with an expected output. An example for a line in this file would be: drw---- 100000f3 00000400 0 ./foo/ My current diff command is diff "$TEMP_LOG" "$DIFF_FILE_OUT" --strip-trailing-cr --changed-group-format='%' --unchanged-group-format='' "$SubLog" As you can see I ignore additional lines in the current output file, I only care about lines that match with the master output. I now have the problem though that some files may differ in size, or a folder might even have a different name, but due to it's location I know what access rights it should have. For example: Output: ------- 00000000 00000000 528 ./foo/bar.txt Master: ------- 00000000 00000000 200 ./foo/bar.txt Only the size differs here, and it doesn't matter, I would like to just ignore certain parts of the diff, kind of like an ansi c comment. Master: ------- 00000000 00000000 /*200*/ ./foo/bar.txt -- OR -- Master: d------ 00000000 00000000 /*10*/ ./foo//*123123*///*76456546*//bar.txt Output: d------ 00000000 00000000 0 ./foo/asd/sdf/bar.txt And still have it diff correctly. Is this even possible with diff, or will I have to write a custom script for it? Since I'm fairly new to cygwin I might be using the completely wrong tool all together, I'm happy for any suggestions. Update: Taking a step back, here is the general task at hand that I want to achieve. I want to write a script that checks the file system to see if the read/write permissions are set up correctly. The structure of the file system is under my control, so I don't have to worry about it changing too much. Sometimes folders/files might not be present, but if they are their permissions must be checked. For Example assume that the following is a snapshot of the current file system structure drw ./foo drw ./foo/bar -rw ./foow/bar/bar.txt drw ./foo/baz -rw ./foo/baz/baz.txt And this is what the file system structure might dictate, i.e. if these folders / files are present, the permissions must match. drw ./foo drw ./foo/bar -rw ./foo/bar/bar.txt --- ./foo/bar/foobar.txt drw ./foo/baz -rw ./foo/baz/foobaz.txt In this case the file system checked out ok, since all files present match their expected values. The situation becomes more complicated as soon as certain folders might have any arbitrary name, only due to their location I know what their permissions should be. Assume that the directory ./foo/bar in the above example might be such a case, i.e. instead of bar the folder could have any name, but still match the -rw permissions. This seems like a very complicated situation, and I'm not even sure if I can solve it with bash scripting alone. I might have to write an actual application.

• 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?

• Mixing JavaFX, HTML 5, and Bananas with the NetBeans Platform

  - by Geertjan

  The banana in the image below can be dragged. Whenever the banana is dropped, the current date is added to the viewer: What's interesting is that the banana, and the viewer that contains it, is defined in HTML 5, with the help of a JavaScript and CSS file. The HTML 5 file is embedded within the JavaFX browser, while the JavaFX browser is embedded within a NetBeans TopComponent class. The only really interesting thing is how drop events of the banana, which is defined within JavaScript, are communicated back into the Java class. Here's how, i.e., in the Java class, parse the HTML's DOM tree to locate the node of interest and then set a listener on it. (In this particular case, the event listener adds the current date to the InstanceContent which is in the Lookup.) Here's the crucial bit of code: WebView view = new WebView(); view.setMinSize(widthDouble, heightDouble); view.setPrefSize(widthDouble, heightDouble); final WebEngine webengine = view.getEngine(); URL url = getClass().getResource("home.html"); webengine.load(url.toExternalForm()); webengine.getLoadWorker().stateProperty().addListener( new ChangeListener() { @Override public void changed(ObservableValue ov, State oldState, State newState) { if (newState == State.SUCCEEDED) { Document document = (Document) webengine.executeScript("document"); EventTarget banana = (EventTarget) document.getElementById("banana"); banana.addEventListener("click", new MyEventListener(), true); } } }); It seems very weird to me that I need to specify "click" as a string. I actually wanted the drop event, but couldn't figure out what the arbitrary string was for that. Which is exactly why strings suck in this context. Many thanks to Martin Kavuma from the Technical University of Eindhoven, who I met today and who inspired me to go down this interesting trail.

• Domain Transfer Protection - need advice

  - by Jack

  Hey, I am about to purchase a domain name for a bit of money. I do not personally know the person who I am purchasing the domain name from, we have only chatted via email. The proposed process for the transfer is: The owner of the domain lowest the domain name security and emails me the domain password, I request the transfer After the request, I transfer the money via PayPal When the money has been cleared the current domain name owner confirms the transfer via the link that he receives in that email I wait for it to be transferred. The domain is currently registered with DirectNIC - http://www.directnic.com/ Is this the best practice? Seeing I am paying a bit of money for this domain name, I am worried that after the money has been cleared that I won't see the domain name or hear from the current domain name owner again. Is there a 'domain governing body' which I can report to if this is the case? Is the proposed transfer process the best solution? Any advice would be awesome. Thanks! Jack

• Supermicro MBD-X9DRL-IF-B and 8 X Hynix 4Gb DDR3 ECC dont boot

  - by Avi Keinan

  I have a custom build server with 2 Xeon E5-2609 and Supermicro MBD-X9DRL-IF-B. Right now the server has 4X Hynix 4Gb 2Rx8 PC3L-10600R-9-10-B0 HMT351R7BFR8A. and its working great. We baught another 4 from the same series of memory, when we installed all the ram (4 sticks already installed and we added 4 new sticks) the server didn't boot. When we replaced the current memory with the new memory - the server did boot. Right now we are in a problem because we need to extend this server ram but the motherboard don't run with 8X4Gb. Any ideas why? I have attached a picture with one of the current memory stick and one of the new memory stick. Thanks in advence.

• freebsd-update from 8.3-RELEASE to 9.0-RELEASE: How to deal with dozens of diffs?

  - by Stefan Lasiewski

  I am upgrading a FreeBSD 8.3-RELEASE system to FreeBSD 9.0-RELEASE using freebsd-update. This is my first time performing a major version upgrade in FreeBSD. At one point in the process, freebsd-update performs a diff on files which are different then what is expected for the 9.0-RELEASE. It compares the current version on the system with the new changes added from 9.0-RELEASE. There are dozens of files in the list. Thus, I am presented with dozens and dozens of diffs which open in a vi window and look like this: The following file could not be merged automatically: /etc/ntp.conf Press Enter to edit this file in vi and resolve the conflicts manually... ### vi window opens <<<<<<< current version driftfile /etc/ntp/drift ======= # # $FreeBSD: release/9.0.0/etc/ntp.conf 195652 2009-07-13 05:51:33Z dwmalone $ # # Default NTP servers for the FreeBSD operating system. # # Don't forget to enable ntpd in /etc/rc.conf with: # ntpd_enable="YES" # # The driftfile is by default /var/db/ntpd.drift, check # /etc/defaults/rc.conf on how to change the location. # >>>>>>> 9.0-RELEASE restrict default notrust nomodify ignore And so on. This requires that I manually edit each file and remove the strings like <<<<<<< current version >>>>>>> 9.0-RELEASE and =======. As I discovered afterwards, if I don't remove these strings, they end up in the file afterwards. There are dozens of files which differ between 8.3 and 9.0, and I have a dozen local modifications myself. It appears that freebsd-update is using a diff, sdiff or mergemaster function of some sort, but I can't tell what it is doing exactly. Processing these files is tedious. Is there a way that I can just say "Accept new version" or "keep old version" or "Your merge is correct"? There has got to be an easier way to deal with these files. I must be missing something. This isn't a huge problem for one machine, but eventually I'll be doing this dozens of times and I want to find an easier way.

• Ubuntu 12.04.1 LTS and Nvidia dirver (304.51) 64bit: problem 640x480

  - by nibianaswen

  I have a problem with this configuration: Asus K55V, Ubuntu 12.04 LTS and Nvidia driver 304.51. I have remove the nouveau driver with: apt-get --purge remove xserver-xorg-video-nouveau I installed the official nvidia driver (from www.nvidia.com) but when I reboot the PC the resolution of screen is only 640x480 and the monitor is resized. Mo solution at this problem if i change the xorg.conf. Now i have uninstall the nvidia driver and reinstall with sudo apt-get purge nvidia-current sudo apt-add-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current When I reboot the screen resolution and size is OK, but if I start nvidia-setting I received the message: You do not appear to be using the NVIDIA X driver. and with command: sudo lshw -c display | grep driver I received configuration: driver=i915 latency=0 This sound like the system is using the Intel card. When I launch command lspci | grep VGA the output is: 00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation Device 1058 (rev ff) And there is no /etc/X11/xorg.conf. I have read a lot of guides on internet but without success.. How i can use nvidia card with the driver that i have installed?

• Launch apps or run commands on Windows via shortcuts

  - by Francisc

  Is it possible to register shortcuts on Windows 7 so that regardless where you are looking (Desktop, a folder etc) the shortcut gets "heard" and the appropriate action is performed. For example, creating a shortcut in the System32 folder which will work if you use Run with the shortcut's name, will not work if you set a key combination when focus is set on the Desktop for example. Is there a native way of registering top-level shortcuts or even an application for enabling this? Example of things I want keyboard shortcuts for: open a specific folder like %path% create a new .js file in the current folder launch an application eventually with its path set to the current location if the app supports this (e.g. command prompt) Thank you.

• How to delete just one LINE of text (NOT a table-row!) with a single KEYBOARD shortcut in Microsoft Office Word 2010?

  - by Sk8erPeter

  Are there any shortcuts to delete just one row (which is NOT a table row, just a single row in a text) in Microsoft Office Word 2010? If not, how can I assign one to do it? In worst case, can I make a macro (in VB) which could do the same with a custom shortcut? To clarify my problem: I would like to avoid multiple clicks and/or pushing multiple buttons, even if I click in the middle of the line of text. :) For example, in Notepad++ I can delete the entire current line with Ctrl+L, in NetBeans, I can delete an entire line with Ctrl+E, in Eclipse, I can delete current line with Ctrl+D, etc., where it doesn't really matter where my mouse cursor is actually... so there are these simple solutions, which I look for in Word too. It really would simplify my work in huge documents.

• Estimate angle to launch missile, maths question

  - by Jonathan

  I've been working on this for an hour or two now and my maths really isn't my strong suit which is definitely not a good thing for a game programmer but that shouldn't stop me enjoying a hobby surely? After a few failed attempts I was hoping someone else out there could help so here's the situation. I'm trying to implement a bit of faked intelligence when the A.I fires it's missiles at a target in a 2D game world. By predicting the likely position the target will be in given it's current velocity and the time it will take the missile to reach it's target. I created an image to demonstrate my thinking: http://i.imgur.com/SFmU3.png which also contains the logic I use for accelerating the missile after launch. The ship that fires the missile can fire within a total of 40 degree angle, 20 either side of itself, but this could likely become variable. My current attempt was to break the space between the two lines into segments which match the targets width. Then calculate the time it would take the missile to get to that location using the formula. So for each iteration of this we total up the values and that tells us the distance travelled, ad it would then just need compared to distance to the segment. startVelocity * ((startVelocity * acceleration)^(currentframe-1) So for example. If we start at a velocity of 1f/frame with an acceleration of 0.1f the formula, at frame 4, would be 1 * (1.1^3) = 1.331 But I quickly realized I was getting lost when trying to put this into practice. Does this seem like a correct starting point or am I going completely the wrong way about it? Any pointers would help me greatly. Maths really isn't my strong suit so I get easily lost in these matters and don't even really know a good phrase to search for with this. So I guess in summary my question is more about the correct way to approach this problem and any additional code samples on top of that would be great but I'm not averse to working out the complete code from helpful pointers.

• Confusion on HLSL Samplers. Can I Set Samplers Inside Functions?

  - by Kyle Connors

  I'm trying to create a system where I can instance a quad to the screen, however I've run into a problem. Like I said, I'm trying to instance the quad, so I'm trying to use the same geometry several times, and I'm trying to do it in one draw call. The issue is, I want some quads to use different textures, but I can't figure out how to get the data into a sampler so I can use it in the pixel shader. I figured that since we can simply pass in the 4 bytes of our IDirect3DTexture9* to set the global texture, I can do so when passing in my dynamic buffer. (Which also stores each objects world matrix and UV data) Now that I'm sending the data, I can't figure how to get it into the sampler, and I really want to assume that it's simply not possible. Is there any way I could achieve this?

• Using glReadBuffer/glReadPixels returns black image instead of the actual image only on Intel cards

  - by cloudraven

  I have this piece of code glReadBuffer( GL_FRONT ); glReadPixels( 0, 0, width, height, GL_RGB, GL_UNSIGNED_BYTE, buffer ); Which works just perfectly in all the Nvidia and AMD GPUs I have tried, but it fails in almost every single Intel built-in video that I have tried. It actually works in a very old 945GME, but fails in all the others. Instead of getting a screenshot I am actually getting a black screen. If it helps, I am working with the Doom3 Engine, and that code is derived from the built-in screen capture code. By the way, even with the original game I cannot do screen capture on those intel devices anyway. My guess is that they are not implementing the standard correctly or something. Is there a workaround for this?

• What causes the iOS OpenGLES driver to allocate extra memory?

  - by Martin Linklater

  I'm trying to optimize the memory usage of our iOS game and I'm puzzled about when/why the iOS GLES driver allocates extra memory at runtime... When I run our game through Instruments with the OpenGL ES Driver instrument the gartUsedBytes value can fluctuate quite wildly. We preload all our textures and build the buffer objects up front, so it's not the game engine requesting extra memory from GL. Currently we are manually requesting around 50MB of GL memory, yet the gartUsedBytes value sits at around 90MB most of the time, peaking at 125MB from time to time. It seems to be linked to what you are rendering that frame - our PVS only submits VBO's for visible meshes. Can anyone shed some light on what the driver is doing in the background ? Like I said earlier, all our game engine allocations are done on level load, so in theory there shouldn't be any fluctuation on GL memory usage while the level is running. Thanks.

• Multiple Graphics cards - Non Multi-Display Setup

  - by Alan Thomas

  Is it possible for me to utilize the processing capabilities of multiple graphics cards, even if I'm only using one monitor? I recently bought a new AMD graphics card, fairly top of the line. I also have a two year old, decent nVidia card. They're obviously very different cards. I don't really mind for gaming because my current card can handle most games fine by itself. I'm concerned about video editing programs such as Adobe Premiere and After Effects. Would the system be able to utilize the power of both cards to, say, render a video? I have both drivers still installed on my machine. And because there is only one monitor connected to my current graphics card (AMD) the nVidia would be connected to no display. So I am wondering whether it would or could be utilized in some way to help in processing video. Thanks!

• Extension GLX missing...on a desktop PC

  - by Bart van Heukelom

  I just installed Ubuntu 12.10 on a new PC with an Nvidia GTX 560 graphics card, but after installing the Nvidia proprietary drivers (either -current or -current-updates), Unity won't start. When trying to start it manually I get the message "extension GLX missing". I've searched around and found results like this question which point out it's a problem with Nvidia Optimus laptops. However, I don't have this problem on a laptop, but on a desktop PC. lshw output for the graphics card: *-display description: VGA compatible controller product: GF114 [GeForce GTX 560 SE] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nouveau latency=0 resources: irq:16 memory:f4000000-f5ffffff memory:e0000000-e7ffffff memory:e8000000-ebffffff ioport:e000(size=128) memory:f6000000-f607ffff and CPU: *-cpu description: CPU product: Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz vendor: Intel Corp. physical id: 40 bus info: cpu@0 version: Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz slot: SOCKET 0 size: 1600MHz capacity: 3800MHz width: 64 bits clock: 100MHz capabilities: x86-64 fpu fpu_exception wp vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx rdtscp constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm pcid sse4_1 sse4_2 popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm ida arat epb xsaveopt pln pts dtherm tpr_shadow vnmi flexpriority ept vpid fsgsbase smep erms cpufreq configuration: cores=4 enabledcores=4 threads=4

• How to perform game object smoothing in multiplayer games

  - by spaceOwl

  We're developing an infrastructure to support multiplayer games for our game engine. In simple terms, each client (player) engine sends some pieces of data regarding the relevant game objects at a given time interval. On the receiving end, we step the incoming data to current time (to compensate for latency), followed by a smoothing step (which is the subject of this question). I was wondering how smoothing should be performed ? Currently the algorithm is similar to this: Receive incoming state for an object (position, velocity, acceleration, rotation, custom data like visual properties, etc). Calculate a diff between local object position and the position we have after previous prediction steps. If diff doesn't exceed some threshold value, start a smoothing step: Mark the object's CURRENT POSITION and the TARGET POSITION. Linear interpolate between these values for 0.3 seconds. I wonder if this scheme is any good, or if there is any other common implementation or algorithm that should be used? (For example - should i only smooth out the position? or other values, such as speed, etc) any help will be appreciated.
