  • Good way of handling class instances in game development?

    - by Bugster
    I'm a new indie game developer, and I've made a few games, but often times when coding I wonder "Is this the way most people do it? Am I doing it wrong?" because I'd like to become a game developer some day, and I really want to get rid of bad practices in time. The way I'm doing it right now is like this: #include <some libraries> #include "Some classes" int main() { Class1 a; Class2 b; Class3 c; a.init(); b.init(); c.init(); // game logic; } Now as I see the game grow, I have more and more classes to initialize and create instances of. This is clean but I'm not sure if this is standard practice. Is this a regular way of creating instances of your game classes or is there a cleaner and more efficient way to do it?

  • Where is the source of domain search? [closed]

    - by All
    There are several websites providing service of searching for free domains (websites, not registrars). I wonder where is the source of these searches? This search cannot be based on local database, as it needs live data (of available domains). The only possible way (to me) is to fetch every query from the original NIC (e.g. nic.com), but I was unable to find an API for this service. How to find a source to write a script for domain searching?

  • Can I stop battery charging at say 80% and switch to AC?

    - by elim
    While I was looking for a battery management utility for my Dell E5420, I came to read this post - How can I limit battery charging to 80% capacity? . Sofar, I haven't found one that relates to my laptop. So, I wonder now if any battery manager utility can be found for my laptop specified above. I would be happy if someone could point me if such utility is available under Ubuntu 12.04 that can stop charging a battery at a certain percentage and to ONLY use A/C mode. Again, to start using battery mode when the A/C is off or when the battery level reaches at certain level. Thanks for all your help. Elim.

  • Java - learning with a simple project

    - by phodu_insaan
    I remember when I learnt PHP, it was suggested that I code a simple blog or a forum after reading the language fundamentals and syntax. I was told/read that this would cover everything that I would learn about PHP in a beginners book. This advice was out there in a number of places, and after following and working with PHP it seems quite good advice. I am now learning Java, and reading the book Thinking in Java by Bruce Eckel. I wonder if there is any such set of similar, small projects that I could take up, that would cover all the essentials and most of what is covered in the book. Thanks.

  • Generate Unique Abstract Backgrounds with Ablaze

    - by Jason Fitzpatrick
    If you want custom and unique backgrounds without having to code your own image-generating engine, Ablaze makes it simple (and fun) to create abstract images. You can customize a wide array of options in Ablaze including the base shape (ring, horizontal line, or random), number of particles, distance each particle travels, and the speed (if you increase the speed range you get more distinct lines and if you decrease it you get smoother smokier shapes). You can also seed the design with a color palette pulled from any image you provide (the sample above was seeded with a Wonder Woman comic panel). Tweak and reset the pattern generation as much as you want; when you create an abstract image worthy of your desktop just click the save button to grab a copy of it in PNG format.

  • Which version of Ubuntu is recommended for Samsung N270 notebook?

    - by Patu
    I have just installed 12.04 LTS 32bit because it was recommended but it seems slow, slightly slower than the EX family edition windows which came with the notebook and I used for 3 years.... so it makes me wonder if this is the correct version of Ubuntu for me. (or.. maybe I need to install the driver for my built in graphic card? or anything else.) specs: Samsung N270 notebook. Intel Atom cpu N270 @ 1.6GH X 2. 1GB RAM I am not sure the type of graphic card I just know that it is built in of Intel. Thank you guys for the help. Patu.

  • Is Google indexing pages that has no connection with other pages? [duplicate]

    - by Grkmksk
    This question already has an answer here: How did Google find my unlinked newly created pages? 3 answers I am working on a web project that has nearly 100 thousand instant users and there is a webpage that we are using for test cases. There are no links pointing to it from other pages. It shouldn't be indexed by Google or any other search engines. "noindex" can be used in this situation, I know but I wonder if Google (or any others) indexes this page, if I don't do anything to prevent it.

  • what is the best way to add avoidance behaviour to an AI framework?

    - by SirYakalot
    I have a small AI framework for a shooting based game. Although this is rarely needed, as when agents are close to each other they are usually fighting, I would none the less like some way of implementing avoidance behaviour. For example, if in the future I wanted to take away their weapons and have many of them wonder around in a crowd, how would I make them not hit / pass through each other, but instead avoid each other? two ideas I had would be to add steering behaviour and allow that to deviate from their path, or to use a dynamic pathfinding technique. Are there better ways? What is the more respected practice?

  • XNA 4.0 - container with content, that can slide (C#)

    - by DijkeMark
    I got an idea, but I got no idea on how to make it. Okay, so here is the deal. I want a container which can contain certain objects (These objects will draw the sprites/graphics). But because of different screen sizes, I want to be able to scale the containers width and height. But I do not want the objects in the container, that go outside of the container, because of the scaling to be visible. Because I want the objects all to be positioned horizontaly to eachother and I want a horizontal sliderbar, so I can slide from left to right within the container. I wonder if anyone could point me in the right direction. Thanks in Advance, Mark

  • Laptop battery sometimes does not charge?

    - by user1880405
    So on my Asus K56C laptop running Ubuntu 14.04 (was same problem in 13.10) I got a problem that from time to time after I use laptop without cable (just on battery) it stops charging with cable. I can still use laptop indefinitely on cable, but it's not charging. The only solution is to remove and reinsert the battery, then it will charge. Now I wonder how does laptop 'knows' that battery was reinserted, and is it possible to simulate that from Ubuntu, maybe some command which refreshes battery? P.s.: this is not happening on Windows 8.1.

  • How can I use LightDM for user-defined sessions?

    - by Philipp
    If I unterstand it correctly, LightDM has replaced GDM per default. I wonder if it's possible to make it run the things I put in my .xinitrc file ... what I need is an option below "Unity" and "Unity 2D" which says "Run a user-defined session". Is that possible? Should be the easiest thing, but I did not get a clue so far. I export and define and run a lot of things in this file, so it's pretty important for me to have control over that. What I do NOT want is a custom session in /usr/some/where, I only want it to run the stuff from each user's xinitrc (or similar).

  • How many LOC/day "top" (google, MS, FB) engeneers produce? [closed]

    - by NoSenseEtAl
    I know that 25 lines of lock free code is harder to do than 1000 lines of On_Click()... code but I wonder does anybody know in general what is the productivity of the average programmer in top tech companies. Motivation: I often go ??? mode when I see how low LoC/ day i produce(Im new to the my current language and Im part of the big project, but still..) and I would like to know how bad I am. :) If you are gonna warn me that LoC is a terrible measure I agree, but it is most exact one in a sense that I cant go and write 0.01% of Chrome or IE and say it took me this long so....

  • Pinging/connecting to server.domain.local never works, but server does when the search domain is specified

    - by SuperMatt
    This is a bit of a weird one. I'm running ubuntu on a Windows domain. If I type "ping server" I can ping correctly and I can connect without any problems. It looks up my search domain (domain.local) and everything is hunky dory. Problem is when I try to ping server.domain.local. It just can't look up the server and comes back with "ping: unknown host server.domain.local" Part of me thinks that the name servers aren't set correctly, but I wonder if there is something I can do to get around it.

  • Ubuntu 14.04 is unstable on my Thinkpad T61

    - by user292386
    I have this super old Thinkpad T61 and installed Ubuntu 14.04 on it. I noticed X11 is quite unstable. It'd freeze all the time, especially after suspension. Sometimes dash would appear as a blue screen, etc, etc. I have tried Xunbuntu as well. It's pretty much the same. But I don't seem to have problem with Debian 7.5. I still prefer Ubuntu to Debian. I just wonder which build of Ubuntu would have similar video/X versions as Debian 7.5. Thanks.

  • Detailed android activity lifecycle (onAttachedToWindow())

    - by Ralkie
    I'm interested in android activity lifecycle and I would like to get more detailed description/documentation/reference than widely available basic (onCreate-onStart-onResume) one. My need comes from realizing that starting new activity (Theme.Dialog styled) from onAttachedToWindow() greatly improves response time if comparing to starting it from onCreate(). I wonder how this onAttachedToWindow() fits into whole android activity lifecycle. Official API ref description "Called when the window has been attached to the window manager" doesn't help a lot.

  • What does it mean to "preconcat" a matrix in Android?

    - by Brad Hein
    In reviewing: http://developer.android.com/reference/android/graphics/Canvas.html I'm wondering translate(): "preconcat the current matrix with the specified translation" -- what does this mean? I can't find a good definition of "preconcat" anywhere on the internet! The only place I can find it is in the Android Source - I'm starting to wonder if they made it up? :) I'm familiar with "concat" or concatenate, which is to append to, so what is a pre-concat?

  • How to be a verified publisher ?

    - by Frank
    I wrote an app and I want to sell it online, so I uploaded it to my website and tried to download and run it as a test, but a window appeared, it said : "The publisher could not be verified. Are you sure you want to run this software ?", and it also said : "Publisher : Unknown Publisher". It's actually a self-signed Java jar file wrapped into an exe file, I self-signed it with Netbeans6.7. I wonder what should I do to be a "known" publisher ? Frank

  • Mac OS X Terminal: mouse support?

    - by avetis.kazarian
    Is there a native option (ie. without installing extra soft/package/plugins) to enable mouse support in the Terminal app? Actually, I'm using a lot vim with the option set mouse=a (activating mouse features). But it seems that Terminal don't support all xterm's features. It appears (after some googling) that Terminal had once the mouse support, but I wonder where did it go. N.B: I really want mouse support in Terminal, not only for vim, so please, don't suggest MacVim :]

  • Performance Testing a .NET Smart Client Application (.NET ClickOnce technology)

    - by jn29098
    Has anyone ever had to run performance tests on a ClickOnce application? I have engaged with a vendor who had trouble setting up their toolset with our software because it is Smart Client based. They are understandably more geared toward purely browser-based applications. I wonder if anyone has had to tackle this before and if so would you recommend any vendors who use industry standard tools such as Load Runner (which i assume can handle the smart client)? Thanks

  • Installing ssl certificates in GlassFish v3

    - by a1ex07
    I have just installed a new ssl certificate on GlassFish 3. I also changed all references to s1as to a new certificate alias in config/domain.xml. Everything seems to work fine, but I wonder if I have to change all "s1as" entries in config/sun-acc.xml, wss-server-config-1.0.xml,wss-server-config-2.0.xml as well ? Do settings in these files affect anything ? Thanks in advance.

  • Iphone resizing images

    - by Greg
    Hi all, As far as I have read, scaling a big image to draw it on the iPhone is very slow [1]. I really need to do it fast and I wonder why zoom goes so fast on the iPhone while code scaling is so slow. Any idea? By the way, any fast way to do scaling? [1] For instance: http://stackoverflow.com/questions/1282830/uiimagepickercontroller-uiimage-memory-and-more Thanks for your time. Greg
