  • Lightning whip particle effects

    - by Fibericon
    I'm currently using Mercury Particle Engine for the particle effects in my game, and I'm trying to create a sort of lightning whip - basically a lightning effect bound to a line that curves when the player moves. I know how to use the editor, and I have particle effects working in game. However, I'm completely lost as to where I should start for this specific particle effect. Perhaps if I could find the code for it in a different particle engine, I could convert it, but I can't seem to find that either. What I did find was a lot of tutorials for creating the lines associated with lightning programmatically, which doesn't help in this case because I don't want it to be rigid. Perhaps it would be more like some sort of laser beam with crackling effects around it? I'm running into a wall as far as even beginning to implement this goes.

  • 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.

  • Speakers will not work after I use USB Headset

    - by Josh K
    I am trying to configure my SteelSeries Siberia V2 Frost USB Headset to work with my 2.0 speakers using a jack. My goal is to find a easy way (no restart) to switch playback from my headset and my speakers and vice-versa. If i plug my headset in and make it the default device then restart my application/web page then the sounds works out of headset. If I switch the default to my speakers and restart apps/web pages then sound does not play. I know my speakers are on because if I configure them through windows and test, the sounds play, and sounds also play when I test it through my audio manager. Even if I unplug my headset, I still cannot get sound out of my speakers unless I restart My audio manager is RealTek HD Audio Manager, Windows 7 x64. I have tried the speaker back, usb front. speaker front, usb in front port. I have not tried speaker back, usb back.

  • A network share folder is invisible to users

    - by Myrddin Emrys
    I have a network share folder that I was recently cleaning up permissions to. I took off the four individual names from the access permissions to the folder, and added a new security group (Universal) with standard Read/Write permissions to that folder, then added those 4 people to the group. However... now nobody can see the folder. The users can see the other 9 folders in that shared drive, but the 10th is missing. I cannot see any security permission in the parent folder or in the folder itself which would cause it to be invisible to anyone, regardless of whether they have permission to open it or edit files within.

  • Kernel Panic Fatal Machine Check

    - by 0x4a6f4672
    I have got a new Samsung Series 7 laptop with dual boot setup for Windows 8 and Ubuntu 12.10. The Ubuntu installation was quite a hassle, but with the help of Boot Repair finally it seemed to work. Or so I thought. Windows 8 starts fine, but if I want to start Ubuntu regularly the following error occurs, quite similar to this one [Hardware Error] CPU 1: Machine Check Exception: 5 Bank 6 [Hardware Error] RIP !inexact! 33 <00007fab2074598a> [Hardware Error] TSC 95b623464c ADDR fe400 MISC 3880000086 .. [similar messages for CPU 2,3 and 0] .. [Hardware Error] Machine Check: Processor context corrupt Kernel panic - not syncing: Fatal Machine Check Rebooting in 30 seconds Kernel panic does not sound good. Then it starts to reboot, and the second boot trial often works. Is it a Kernel or driver problem? The laptop has an Intel Core i7 processor. I already deactivated Hyperthreading in the BIOS, but it does not seem to help :-(

  • How to deal with OpenGL and Fullscreen on OS X

    - by Armin Ronacher
    I do most of my development on OS X and for my current game project this is my target environment. However when I play games I play on Windows. As a windows gamer I am used to Alt+Tab switching from within the game to the last application that was open. On OS X I currently can't find either a game that supports that nor can I find a way to make it possible. My current project is based on SDL 1.3 and I can see that cmd+tab is a sequence that is sent directly to my application and not intercepted by the operating system. Now my first attempt was to hide the rendering window on cmd+tab which certainly works, but has the disadvantage that a hidden OpenGL window in SDL cannot be restored when the user tabs back to the application. First of all, there is no event fired for that or I can't find it, secondly the core problem is that when that application window is hidden, my game is still the active application, just that the window disappeared. That is incredible annoying. Any ideas how to approximate the windows / linux behavior for alt+tab?

  • Do you think Scala will be the dominant JVM langauge, ie be the next Java? [on hold]

    - by user1037729
    From what I've read about Scala do far I think it has some nice features but I do not think it should be "the next Java". It might however end up being the next Java (due to fashion rather than fact) but lets not hope it does not... To me adds a lot of complexity over Java which is a simple and scalable language. Scala Pattern matching allows you to perform some type/value checking in a more concise way, this is possible in Java, Scala's pattern matching has a limit to it, you cannot continuously match deeper and deeper down the object graph, so why not just stick to Java and use decent invariants? Scala provides tuples, easy enough to make in Java, create a static factory method and it all reads nicely too. Scala provides mixins, why not just use composition? I believe Scala implicit's are bad, they can lead to code becoming complex and hard to maintain, explicitness is good. Scala provides closures, well they will be in Java 8 too. Scala has lazy keyword for lazy instantiation, this is easy enough to do in Java by calling a getter which creates the instance when needed, no hidden magic here. Scala can be used with AKKA, well so can Java, there is an Java AKKA implementation. Scala offers addition functional features but these can all be created in Java, there are many frameworks with have implemented functional features in Java. All in all Scala seems to offer is addition complexity and thats it...

  • Security measures for CentOS

    - by cappuccinodrinker
    I have been tightening up my web server security and wanted to know what else I can do. I am running CentOS 5 with these measures: - All passwords to FTP, MySQL etc are generated from grc.com/passwords.htm and microsoft.com/protect/fraud/passwords/create.aspx (for the ones which cannot be too long). - Running iptables with all ports shut off except for http mail and smtp, the important ports like FTP SSH are blocked to all except my static office IP. There is also no response to pings. - Rootkit Hunter running daily - The server is PCI compliant according to Comodo - Not running any crappy made php apps, we use Zend Framework for our stuff and do have kayako installed and keep them up to date. Can't really think of anything else I can do... I could implement a brute force measure, but I think I already have by simply changing my SSH port to a number above 10000 and blocking it off with iptables.

  • Add Multiple Types of Items to the Desktop Context Menu in Windows 7 or 8

    - by Lori Kaufman
    The context menu in Windows provides a convenient place to start programs, access websites, and open folders. There are several ways to add programs to the menu including a registry method and a free tool. We’ve found another free tool, called Right Click Context Menu Adder, that allows you to add more than just programs to the desktop context menu and the folders context menu. It allows you to add folders, web addresses, and files to the menus, as well as programs. Right Click Context Menu Adder is portable and doesn’t need to be installed. To run it, simply extract the .zip file you downloaded (see the link at the end of this article) and double-click on the .exe file.

  • Problem starting Compiz: symbol lookup error for libdecoration.so

    - by AniDev
    I run Ubuntu 10.10 (Maverick). I had removed Compiz 0.8.x from my system so I could try out Compiz 0.9.x. I then decided that I wanted Compiz 0.8.x back, so I installed the packages from aptitude. Now, when I try to start Compiz, I get this error: compiz: symbol lookup error: /usr/lib/compiz/libdecoration.so: undefined symbol: decor_property_to_quads Using the command "readelf /usr/lib/compiz/libdecoration.so -s", I see that that symbol is present: 24: 00000000 0 FUNC GLOBAL DEFAULT UND decor_property_to_quads Aptitude reports that my Compiz core packages (like compiz, compiz-core, compiz-plugins, etc.) are at version 1:0.8.6-0ubuntu9.1. Does anyone have any ideas why Compiz is reporting this error, and/or what I can do to fix it? I cannot run Compiz, because this error causes Compiz to abort, even if the "Window Decoration" plugin is not enabled.

  • How to Choose a Web Developer to Create Your Online Template Site

    Online template systems are found online, and, typically offer you an "easy" and inexpensive way to build your website. Notice the quotations about easy. The actual process of building and maintaining the online template site might not feel like it's easy and inexpensive. The reality is that, in most cases, it really is easier to use an online template system than it is to start a new website from scratch. Also, you can get a site up much more quickly because the internal structure and background images of the site are already done. However, you should choose a developer that has some experience in this area.

  • Symbol of VPNanytime is not shown anymore after upgrading from Ubuntu 11.04 to 11.10

    - by Aufwind
    Usually when I start VPN anytime (by calling a certain url in firefox) in Ubuntu 11.10 I saw a little "green symbol with a yellow lock in front of it" for the VPN anytime client near the clock. If I wanted to quit the VPN connection I just clicked on this symbol and hit logout/quit. Today I upgraded to Ubuntu 11.10 and the VPN connection works here fine too. But the symbol near the clock is not shown anymore. Is this a bug or do I have to set this up manually? And is there a way to quit the client perhaps by terminal? Currently I just do a restart, when I want the vpn connection terminated and that's kind uncomfortable. :-) Thanks for any suggestions!

  • Blender 2.63a window position unstable with dual monitor extended desktop

    - by Steve Smith
    I have two 1920 x 1200 HP monitors and running Ubuntu 12.10. If I set them up as an extended desktop, (both 1280 x 1024 positioned for 2048 x 1280, all my applications work fine EXCEPT Blender (even Inkscape). Blender works great on a single monitor but always defaults to a window size that uses all available real estate and it can't do that with 2048 x 1280. It launches, but jumps all over the screen. Does any know a way to start Blender in a fixed size window so it would run in just one monitor?

  • Why using Acrobat 10 resaving a PDF file that was 4MB will become 3MB?

    - by Jian Lin
    I had some PDF files and just try to open it and do some highlighting using Acrobat 10 (also called Adode Reader X)... After highlighting, I save the file (using a different filename), and now the file change from 4MB to 3MB... is it just compression? Or making the images have lower clarity? (thought I cannot see any difference). What is the reason? If it is just compression, then why wasn't it done before, as winzip technology is quite mature more than even 10, 12 year ago.

  • Too many processes?

    - by Mophily
    VMware Fusion v3.0.1 One vm for Windows XP, converted and recently expanded the disk size. Mac OS X 10.5.8, 2 x 3 GHz dual-core intel xeon machine. Immediately after booting, and before VMware Fusion is launched, the Activity Monitor shows eight processes associated with "vm". What caught my eye is the duplicates: netifup and dhcpd. I noticed this while trying to re-establish network connectivity after the upgrade to 3.0.1. I am not sure when the network connection was clobbered, so I cannot say it happend during the upgrade. Is eight processes typcial? I expect about six, as listed in other notes and documents on the web site. Could this be related to the failure to connect to the network?

  • Adobe Illustrator - Objects are Expanded on Restart

    - by Shatou Dev
    I use Adobe Illustrator extensively for mobile development. For example, for Android app, I have many illustrations with different densities and sizes. I use many effects such as outer glow, round corners and such. However, sometimes, when I close the .ai file and re-open it later, I found all my objects expanded. Effects are expanded. For example, the round corner effect is now expanded and I cannot re-size any object. I am using a MacBook Pro. I am suspecting both Time Machine and Dropbox. As much as I can recall, it also appears with CS6 version, not CS5.

Can someone please give me a step by step tutorial on how to do it. Please do not think you are being to specific, because I am sure it will help me.

  • Invoking an MMC Snap-in function from Windows command shell: is it possible?

    Sorry for the cross post on Superuser, but I cannot see any answer to my question, so I try to ask the same question here. I need to execute a MMC Snap-in function from the Command Shell of a Windows computer. I need it to schedule this command in the same Windows PC and executes in background. Probably this questions could seem a little bit strange but I have a program that creates a debug log only through its MMC Snap-in console. And I need to automatise this task to programatically read this log! Dows anyone know how to do this? thanks

  • Launcher icons are invisible after upgrade from 11.10 to 12.04

    - by Clo Knibbe
    I am re-purposing an old laptop. I installed 11.10 on it and then immediately upgraded to 12.04. (I could not directly install 12.04 as my system does not support PAE.) When my system was (briefly) 11.10, the desktop appeared as expected. However, after the upgrade to 12.04, the icons in the launcher area are invisible. If I hover over the spot where the icon should be the little popup window showing the tool's name appears, and I can click to invoke the tool. I just cannot see the icons. ![invisible icons in launcher][1] The icons do appear as expected in other contexts, for example in the Home folder and in Dash Home. My theme is "Ambiance (default)" I do not have a ~/.icons folder. This is the top level contents of /usr/share/icons: default DMZ-Black DMZ-White gnome handhelds hicolor HighContrast HighContrastInverse Humanity Humanity-Dark locolor LoginIcons LowContrast redglass ubuntu-mono-dark ubuntu-mono-light unity-icon-theme whiteglass (Sorry for the poor formatting, can't get it to show in list.) I suspect that the launcher isn't looking for the icons in the right place, but I don't know how to confirm that, or how to correct. This is my first foray into Linux, although I used to use Unix a few decades ago. This doesn't look much like my old Sun workstation, though! Does anyone have any suggestions or insights for me? Thanks.

  • Can't login to SQL Server after moving machine to different office/domain

    - by Dan
    Our company has just been bought and the over the weekend I have brought up the last few machines to plug into their network (they are under a different Windows Domain). The last machine is our Vault system and the SQL Server was using Windows Authentication. I have plugged it into their network and its working fine, but i cannot connect to SQL Server with Management Studio and, I fear, no backup jobs will also be working. When I try to login under Windows Auth, it has the user name of "NEWDOMAIN\Administrator" (greyed out) and then presents a "login failed" message with error code "18456". Can anyone help me with this, or will I just have to reinstall SQL Server, Vault and restore the backup I took before the move?

  • Website hosted on IIS is not accessbile

    - by Tola Odejayi
    I have two sites set up in IIS on a remote machine RM; one on regular port 80, and the other on port 5773. From my local machine LM, I can access the site on 80, but I cannot access the one on 5773; I get a status code of 502 and an error code of 10060 (A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond) when I try to do this. I can access the 5773 site via IIS when I am logged into RM (i.e. by right clicking on a page on the site and going 'Browse'). I can also access pages on the 5773 site via a browser, again when I am logged into RM. I just can't do the same via a browser when I am logged into LM. I have ensured that port 5773 is open for outgoing traffic on LM. Could the problem be that I also need to ensure that port 5773 is open for inbound traffic on RM?

  • VGA no signal on LCD monitor attached to laptop

    - by Paul
    I bought a new Asus vh242h LCD monitor for use with my lenevo T60 laptop running XP professional. Display info under control panel says "Intel(R) 945GM Express Chipset Family". I am connecting via VGA. When I connect the monitor I get "VGA no signal" and the monitor screen stays blank. I have selected the monitor as the display device on the laptop. The information on the monitor displays the correct screen resolution from the laptop, so the monitor is communicating in some way with the laptop. I've successfully tried the monitor with my Dell inspirion 1525 running Windows Vista. I've change the VGA cable to one I know works. Tried different resolutions. I cannot find and specific drivers on the internet for this monitor, so I assume it should work with Plug and Play. Does anyone know what the problem could be?

  • problem with using polish keyboard with synergy 1.4.2

    I installed synergy on Windows 7 as server and on Windows Vista as client. On both I can use polish keyboard using local keyboard. When I am using remote keyboard via synergy polish characters are not working (I mean in example S + Alt Gr or S + left Alt + left ctrl) I've used synergy about 1 year ago and I cannot recall that kind of problem so I think the problem is only in current version. Searching through your web site and googled I found only identical problem 5 years ago with information that it was solved. Please help me to sort it out.
