• Ideas for attack damage algorithm (language irrelevant)

  - by Dillon

  I am working on a game and I need ideas for the damage that will be done to the enemy when your player attacks. The total amount of health that the enemy has is called enemyHealth, and has a value of 1000. You start off with a weapon that does 40 points of damage (may be changed.) The player has an attack stat that you can increase, called playerAttack. This value starts off at 1, and has a possible max value of 100 after you level it up many times and make it farther into the game. The amount of damage that the weapon does is cut and dry, and subtracts 40 points from the total 1000 points of health every time the enemy is hit. But what the playerAttack does is add to that value with a percentage. Here is the algorithm I have now. (I've taken out all of the gui, classes, etc. and given the variables very forward names) double totalDamage = weaponDamage + (weaponDamage*(playerAttack*.05)) enemyHealth -= (int)totalDamage; This seemed to work great for the most part. So I statrted testing some values... //enemyHealth ALWAYS starts at 1000 weaponDamage = 50; playerAttack = 30; If I set these values, the amount of damage done on the enemy is 125. Seemed like a good number, so I wanted to see what would happen if the players attack was maxed out, but with the weakest starting weapon. weaponDamage = 50; playerAttack = 100; the totalDamage ends up being 300, which would kill an enemy in just a few hits. Even with your attack that high, I wouldn't want the weakest weapon to be able to kill the enemy that fast. I thought about adding defense, but I feel the game will lose consistency and become unbalanced in the long run. Possibly a well designed algorithm for a weapon decrease modifier would work for lower level weapons or something like that. Just need a break from trying to figure out the best way to go about this, and maybe someone that has experience with games and keeping the leveling consistent could give me some ideas/pointers.

• Memory Glutton

  - by AreYouSerious

  I have to admit that I can't get enough storage. I have hard drives just sitting around in case I need to move somthing, or I'm going to a friends and either they want something I have or I want something they might have. What I'm going to talk about today is cost effective memory for devices. I don't know how this particualr device will work in a camera, as That's not what I use in my camera, in fact I don't have a camera that doesn't either use SD, or the old compact flash card, that's not so compact anymore. There's this thing that uses two micro sd cards to double the capacity of your memory, and it costs about 4 bucks, without the Micro SD card. I have had one for about a year and was going to throw it away because I couldn't get it to work with my computer, or with my Sony Reader. However I found out by one last ditch effort that this thing works beautifully with my Sony PSP. there is no software to speak of associated with this thing, you simply put in two SD cards of the same size... (if you put in two different sizes it will still work, you'll only double the smallest cards size though) and format through the psp. Viola you know have a 29 GB memory card for your PSP. why is this important ? well for starters you can carry more music and more videos. Second if you have gone the way of the hacker.... you can store more games on your card... There are just a few things you have to note.... I speak from experience... you have to use the usb connection to the PSP to do any file moving, as I said previously said card doesn't play well with my computers or card readers... I not saying it won't work at all, just hasn't work with anything I own. Second. If for some reason you try to Hack/crack your PSP don't attempt to delete a game from the psp, use the usb file browser to remove games. if you delete from the PSP you are likely to have to move all your files off, reformat and start again... just a couple things I have noticed... if I had done something like that.   anyway, Here's a link.... http://www.photofast-adapter.com/  and if you want to buy one, get it off ebay, I've seen them as low as $1.99

• How to find history of shell commands since machine was created?

  - by Edward Tanguay

  I created an Ubuntu virtualbox machine a couple weeks ago and have been working on projects off and on in it since then. Now I would like to find the syntax of some commands I typed in the terminal a week ago, but I have opened and closed the terminal window and restarted the machine numerous times. How can I get the history command to go back to the first command I typed after I created the machine, or is there another place that all the commands are stored in Ubuntu?

• How can I tell if I am out of inotify watches?

  - by Jorge Castro

  I use an application that consumes inotify watches. I've already set fs.inotify.max_user_watches=32768 in /etc/sysctl.conf but last night the application stopped indexing unless I ran it manually, which leads me to suspect I am out of watches. Since I don't know what the trade off is when I increase this number (does it consume more RAM?), I don't know if I should just increase this number, so I'd like to know if there's a way I can tell if it's using all these watches and what the tradeoffs might be for increasing it.

• Not able to change flash settings

  - by Zeyu

  My Gnome crashes constantly when I open web pages containing flash so I tried to turn off the hardware acceleration. I opened the Adobe flash player settings panel but found that the buttons are not clickable. I can still switch between display/privacy/storage.. panels using TAB and ENTER key. But for others like the "Enable hardware acceleration" checkbox this won't work. Anyone knows how to solve it? Thanks.

• After last update Unity no longer works

  - by Alen

  An hour ago I installed latest updates and now Unity doesn't work anyomore, I only see desktop with icons. Manually searching I opened system monitor and found out only 400 Mb of RAM is taken which means complete Unity is turned off. Can someone help me to fix this. Since I'm crippled I probably won't be able to provide you with all details you need because I don't have window borders, no right click menu, nothing, only Nautilus.

• Maya .IFF plugins for Gimp

  - by Kara Marfia

  Maya's preferred format for saving off a UV Snapshot is its own .IFF format, so I was hoping to find a plugin allowing Gimp 2 (Windows) to read it. I've found plenty of plugins for different linux distros, but none are win-friendly (that I can discern - admittedly I'm no whiz with Gimp). Does anyone know of one? Alternately, .tiff seems to work just fine, so if there's no good reason to bother fiddling with IFFs, I'd appreciate the input there, too. (sorry if this isn't on-topic)

• What is the status in 3D technology for TVs [closed]

  - by Eduardo Molteni

  Maybe it is off-topic for programmers.SE, but don't know where else to ask, and I trust my fellow programmers :) I've recently being lightly following new 3D technologies and I thought that glass-free 3D TV was about to take over the scene since it make much more sense to TVs (I can't imagine having glasses for all the family, kids breaking them, etc) But it seems that I'm wrong, since LG, Sony and Samsumg keep fighting over glasses (active-passive) What is the current and future status in 3D technology for TVs?

• NuGet JustMock

  - by mehfuzh

  As most of us already know JustMock got  a free edition. The free edition is not a stripped down of the features of the full edition but I would rather say its a strip down of the type you can mock. Technically, free version runs on  proxy as full version runs on proxy + profiler. In full version, It switches to profiler when you are mocking final methods or sealed class or anything else that can not be done using inheritance. Like in full version you can mock non public methods , in free version you can still do it but it has to be virtual for protected or must be done through InternalsVisibleTo attribute for internal virtual methods (If you have access to the source and can apply the attribute). Now, you can get a copy of free edition from the product page. Install it and off you go. But it is also exposed to NuGet. Those of you are not familiar with NuGet (that will be odd). But still NuGet is the centralized package manager from Microsoft that cuts the workflow of manual inclusion of  libraries in your project. I think NuGet in future will limit the scope of  “.vsi” packages and installers because of its ease (except in some cases). Its similar to ruby gems. In ruby, virtually you can install any library in this way “gems  install <target_library>” and you are off to go. It will check the dependencies, install them or less prompt with the steps you need to do.   Now sticking to the post, to get started you first need to install NuGet package manager. Once you have completed the step pressing “Ctrl + W, Ctrl + Z” it will bring up an console like one below:   Once you are here, you just have to type “install-package justmock” Next, it will should print the confirmation when the installation is complete: Moving to visual studio solution explorer, you will now see:   Finally, NuGet is still in its early ages and steps that are shown here may not remain the same in coming releases, but feel free to enjoy what is out there right now. Regarding JustMock free edition, there is a nice post by Phil Japikse at Introducing JustMock Free Edition. I think its worth checking if not already.   Have fun and happy holidays!

After 10-12 minutes the screen goes black/blank when i dont do anything (idle). I have tried setting in the Brightness and Lock menu that the screen should never lock or turn off if idle. This is very annoying when watching movies etc... Would be nice if someone knows this.... Thanks...

I use Nvidia GT9500 videcard in Twinview mode. I can't use Xinerama because vpdau doesn't work correclty in this mode.

• GPU hung when switching graphic card

  - by Lie Ryan

  I have a laptop (Dell Inspiron N4110) with a switchable graphic. $ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: ATI Technologies Inc NI Whistler [AMD Radeon HD 6600M Series] (rev ff) Normally, my laptop starts with both graphic cards enabled, which caused the laptop to turn very hot and the fan to become very noisy. I have been using a small script to disable the Radeon card. For some time, I'm quite happy with this arrangement. However, I have been having some issues with the Intel card (IGD), the Intel card often randomly hang when running OpenGL apps; and so I want to give the Radeon card (DIS) another chance. I have never been able to switch to the Radeon card, but recently, I found out that if I do a "delayed switching" (DDIS): # echo "DDIS" > /sys/kernel/debug/vgaswitcheroo/switch root@lieryan-dell-ubuntu:/sys/kernel/debug/vgaswitcheroo# cat switch 0:IGD:+:Pwr:0000:00:02.0 1:DIS: :Pwr:0000:01:00.0 then I logoff (i.e. to restart X), the screen switch to pseudo-tty and then it stuck there freezing. At this situation, mouse and keyboard stops working so I can't switch to another ptty. I tried ssh-ing from another computer to salvage logs (dmesg at that point) and whatnot; I found out that when freezing, the active graphic card is the AMD card: -- this is from ssh -- # cat switch 0:IGD: :Off:0000:00:02.0 1:DIS:+:Pwr:0000:01:00.0 but the GPU is apparently hung, looking at dmesg gives: ...

I were able to successfully recover by switching back to the Intel card and restarting X from ssh; indicating that only the Radeon card has problems switching.

Distributor ID: Ubuntu Description: Ubuntu 11.10 Release: 11.10 Codename: oneiric The laptop also do not have the option to set graphic card at BIOS and the proprietary driver, fglrx, also have never worked; when I installed it through jockey ("Additional Drivers"), glxinfo showed that it still being rendered by Mesa, the /sys/kernel/debug/vgaswitcheroo directory has gone missing, and the driver crashes with a traceback if I use xorg.conf to tell X to use fglrx. Anyone had any idea if it is possible to use this AMD card either with the radeon or the fglrx driver? logs: dmesg

• "mcp power or thermal limit exceeded" excessive in messages.log

  - by Stefan Thyberg

  I keep getting "mcp power or thermal limit exceeded" every five seconds while my computer is on, regardless of what it's doing. I googled it and found some Intel patches but I don't really know exactly what they do or how to apply them and I also don't want to patch my kernel with these random bits of code from some newsgroup. Can anyone shed some light on what exactly is going on and what the right fix is in this case? Am I better off just waiting for a kernel patch?

• Friday Fun: Destroy the Web

  - by Mysticgeek

  Another Friday has arrived and it’s time to screw off on company time. Today we take a look at a unique game Add-on for Firefox called Destroy the Web. Destroy the Web Once you install the Add-on and restart Firefox, you’ll see the Destroy the Web icon on the toolbar. Click on it to destroy whatever webpage you’re on.   The game starts up and gives you a 3 second countdown… Now move the target over different elements of the page to destroy them. You have 30 seconds to destroy the site contents. If you are angry at a particular company or the one you work for, this can give you some fun stress relief by destroying it’s website. After you’ve destroyed as much of the page as possible, you’re given a score. You get different amounts of points for destroying certain elements on the page. Basically destroy as much as possible to get the most points. You can submit your score and check out some of the scoreboard leaders as well.  There are some cool sound effects and arcade sounding background music, so make sure to turn the volume down while playing. Or you can go into the Add-on options and disable it. If you want a unique way to let off some steam before the weekend starts, this is a fun way of doing it.

• airplanes operating system and choice of programing language

  - by adhg

  I was wondring if anyone knows what is the operating system used in commercial airplanes (say Boeing or Airbus). Also, what is the (preferred) real-time programing language? I heard that Ada is used in Boeing, so my question is - why Ada? what are the criteria the Boeing-guys had to choose this language? (I guess Java wouldn't be a great choice if the exactly in lift off the garbage collector wakes up). Thanks!
