• Game Sound Effects Availability

  - by Ben

  Is there a need in the community for affordable game-focused sound effect packs? I am considering putting together some effects specifically geared toward games and indie developers that desire to get a working prototype quickly off the ground. Is there a need for this, or is there another standard "go-to" spot for this kind of thing? I want to offer value to the community but wanted to assess the need first. If anyone has thoughts, insight, or personal opinions on this I would love to hear it!

• Sounds to describe the weather?

  - by Matthew

  I'm trying to think of sounds that will help convey the time of day and weather condition. I'm not even sure of all the weather conditions I would consider, and some are obvious. Like if it's raining, the sound of rain. But then I'm thinking, what about for a calm day? If it's morning time, I could do birds chirping or something. Night time could be an owl or something. What are some good combinations of sounds/weather/time to have a good effect?

• Should all foreign table references use foreign key constraints

  - by TecBrat

  Closely related to: Foreign key restrictions -> yes or no? I asked a question on SO and it led me to ask this here. If I'm faced with a choice of having a circular reference or just not enforcing the restraint, which is the better choice? In my particular case I have customers and addresses. I want an address to have a reference to a customer and I want each customer to have a default billing address id and a default shipping address id. I might query for all addresses that have a certain customer ID or I might query for the address with the ID that matches the default shipping or billing address ids. I'm not sure yet how the constraints (or lack of) will effect the system as my application and it's data age.

• How are realistic 3D faces created and animated in video games?

  - by Anton

  I'm interested in being able to create realistic faces and facial expressions for the 3D characters of a game I'm working on. Think something similar to the dialog scenes in games like Mass Effect. Unfortunately I'm not sure where to begin. I'm sure the faces/animations are created through 3D Modeling software, but otherwise I am lost. Do facial animations use the same "bones" that normal body animation uses? Is there any preferred 3D software for realistic faces and animations? Is there a preferred format to export these faces and animations in?

• How to reset the Xorg / xserver in 12.04 Precise Pangolin

  - by thomas

  xserver keeps crashing on my general user account both in unity 3d and 2d. It doesn't do it on the guest account. That's why I want to reset / rollback everything xserver related, hoping this is going to fix it. Most answers on this involve sudo dpkg-reconfigure xserver-xorg. However, this does nothing for me (generates no output) and I read in other forums, that it's deprecated. So, what's the current way to reset all xserver / xorg options; what's the alternative to sudo dpkg-reconfigure xserver-xorg ? Thanks Edit: X crashes during work, not before login or so. And the effect of a crash is, that I get thrown out of the session, not a freeze or machine crash.

• game performance

  - by iQue

  I'm making a game for android, and earlier today I was trying to add some cool stuff to my game. The problem is this thing needs like 5 timers. I build my timers like this: timer += deltaTime; if(timer >= 2.0f){ doStuff; timer -= 2.0f; } // this timers gets stuff done every 2 secs Will having to many timers like this, getting checked every frame, screw up my games performance? The effect I wanted to add was a crosshair every 2 sec, then remove it after 2 sec and do a timed animation. So an array of crosshairs dependent on a bunch of timers to be exact. This caused my game to shut down when used, so thats why Im wondering if using that many timers causes my game to flip out.

• Adobe-Flash-plugin freezes when skipping ahead

  - by piedro

  I am using Firefox 7 and the new official Adobe Flash 64-bit plugin from the Ubuntu Partner repository. It's the adobe-flash package. It works nicely on the first look but when I try to skip ahead in any YouTube video (by clicking on the video progress bar) sound will go on but the video simply freezes at the position it was just before skipping. This is really annoying because I really don't want to watch every video full length. Now maybe there's cleanup work to do? I removed every Flash-related package from the package manager. Maybe it's Firefox? I couldn't find any hint. Maybe it's the video manager (display manager)? I am using KDE on an Ubuntu Natty install. I also enabled hardware acceleration with libdvpau1: sudo bash -c "echo 'EnableLinuxHWVideoDecode=1' >> /etc/adobe/mms.cfg" (this seems to have no effect at all ...) Ubuntu Natty 64-bit, Firefox 7, Flash 11.01 )

• Is there a global "low resolution" filter for OpenGL?

  - by Ian Henry

  I'm trying to learn a little about OpenGL, so I'm making a simple 2D game (with OpenTK), and so far it's coming along well. I thought it would be fun to give it that, for lack of a better word, retropixelated look of games from the early nineties. I figured it would be an easy thing to do -- simply draw everything at half its normal size and scale up with no anti-aliasing. But I can't find any resources on how to do this. I can set the min/mag filters of my textures to nearest and that works fine for my sprites, but I'm using lots of primitives and I'd like the effect to apply to them as well. The one idea I had was to draw everything at half size, then somehow copy the render buffer to a texture, then render that texture full-size, but I don't know how to do that, and it seems like there must be a better way. Can anyone help me out?

• Murali Papana Blogs About Date Effectivity

  - by steve.muench

  Murali Papana from our Human Capital Management (HCM) Fusion Applications team has posted a series of blogs on a lesser-known, but quite powerful feature of ADF called "date effectivity". This is a feature that allows the framework to simplify managing records whose data values are effective for a given period of time. Imagine an employee's job title or salary that changes over time, which as well might be entered today by an HR reprepsentative but go into effect at some time in the future.

• Reassign the Right button functionality of touchpad

  - by Guandalino

  My notebook has a touchpad with two buttons. The touchpad works pretty well and I use it for vertical/horizontal scroll, two fingers scrolling etc. The Left button acts like the left button of a mouse. The Right button too, when clicked it makes appear the classic contextual menu (create new folder, move to trash etc...). The problem is that Right button doesn't work anymore for mechanical reasons, so pressing it has no effect. To recover the missing functionality, I'd like that pressing CTRL + Left button I get the same thing of pressing the Right button alone. Other combinations (CTRL + SHIFT + Left button) are also acceptable. Any way to do that?

• I'm not sure if this is a valid Ubuntu bug to file

  - by Ian Hincks

  I was in the process of filing an bug on Launchpad, but I had second thoughts because there were so many threatening warnings of the effect, "Don't file a bug report unless you're sure it's a bug, and you should really provide a package name". The problem I have, and I've had it for years, is the following: When I'm installing Ubuntu, it asks me to type in my location before it asks me what my keyboard layout is. Using a QWERTY keyboard but with the buttons popped of and in the Dvorak order, this is annoying, because it is assumes I am using a QWERTY keyboard, and so I have to guess at where all the QWERTY keys are to spell my city's name. It seems like it would make more sense to switch the order of these two questions. (I'll be the first person to admit that this is a very minor problem that has probably wasted less than 2 minutes of my life in total -- but it's the principle of the thing :p) So my question is: is this order there for a particular reason, and if it isn't, is it appropriate to file it as a bug, and under which package name?

• Enforce VPN connection to access the Internet

  - by ch0wn

  I'm using a VPN when I'm online at an unencrypted wifi. Unfortunately, at my university the connection is quite unstable and at every reconnect the VPN connection is terminated and I manually need to reconnect to it using the NetworkManager, which obviously only works if I notice the reconnect. I enabled the option to automatically connect to the VPN in the NM options, but it seems to have no effect. Is there a way to enforce an active VPN connection before any other application can access the network connection so I can be sure not to send private data over unencrypted connections? Cheers, Pascal

• Simulating an object floating on water

  - by Aaron M

  I'm working on a top down fishing game. I want to implement some physics and collision detection regarding the boat moving around the lake. I would like for be able to implement thrust from either the main motor or trolling motor, the effect of wind on the object, and the drag of the water on the object. I've been looking at the farseer physics engine, but not having any experience using a physics engine, I am not quite sure that farseer is suitable for this type of thing(Most of the demos seem to be the application of gravity to a vertical top/down type model). Would the farseer engine be suitable? or would a different engine be more suitable?

• Compiz effects aren't working properly!

  - by Naveen

  On Ubuntu 12.04, the Compiz visual effects appears to be glitchy. I see a "window flash", after rotating the "Desktop Cube". I've used the "Magic Lamp effect" when minimizing windows, but the window content, minimizes faster, delaying the window border to minimize. "So the border and the window content gets apart, like in the picture below". I've tried updating Compiz, but no luck. How to fix this problem? Will Compiz work properly in XFCE? This didn't happen in Lucid Lynx. I appriciate any help!

• Cannot assign keys to Wacom scroll wheel anymore

  - by UncleZeiv

  Hi all, my Wacom Graphire 4 used to work perfectly well until, I think, Ubuntu 10.4. At that point something changed in the configuration and I couldn't assign a key to the scroll wheel anymore (note: the pad's scroll wheel, not the mouse's), i.e this command: xsetwacom set "Wacom Graphire4 6x8 pad" AbsWDn "key +" returns silently without error but nothing happens. Same goes for AbsWUp, RelWDn, RelWUp. Apparently though the problem is even deeper as pressing the wheel in a xev window doesn't seem to have any effect. Moreover I am thoroughly confused on how the various pieces (kernel driver, xorg driver, evdev, HAL, xinput?) are supposed to work together and if the wacom module that ships with Ubuntu is the one from linuxwacom or not. Any ideas? I don't want to become an X.org hacker just to understand what's going on... it used to work! NOTE: I have already read question 3940, but that's not the same problem.

• Downgrade to LTS version, preserving /home partition: Should I expect this to work?

  - by Archelon

  Specifically, I'm installing Kubuntu 12.04 over 13.04. And in fact I've already done it, and it seems to have at least mostly worked, but I'm wondering whether this one anomaly is likely to be attributable to the downgrade; to wit: I have no window borders|decorations, but only wide, featureless, white---or sometimes black---margins around all my windows. None of the settings in System Settings (the window border and decorations options are in Workspace Appearance) seem to have any effect. Is this likely to be fixable, or should I cut my losses and reinstall (formatting the /home partition and restoring any data with rsync)?

• Unity does not display properly [closed]

  - by Ben Isaacs

  Ubuntu Unity on the Ubuntu netbook edition installs without a problem but when I log in though, where the panels are, there is just blank area with a shadow effect style thing on it. I can open apps but the Window buttons and the global menu are not visable. Does this mean that I cannot use Unity. I'm running it through Wubi on a Dell Inspiron 1501 laptop. My total ammount of graphics memory is 831MB My dedicated memory is 128MB. The odd thing is is that Windows Aero displays without a problem so why is there a problem with Unity Hope this helps Ben

• Unable to drag brush tool in Photoshop CS5 in 12.04

  - by Rodrane

  I was able to use Photoshop CS5 perfectly on Ubuntu 11.10. After upgraded to 12.04 I've noticed that when I try to use brush tool in by dragging the left mouse button I cannot get continous effect on photos. It only effects the area I click with mouse. In the screenshot all the time I was holding the left mouse button but it only affected the image once, creating dots instead of lines. At first I thought its something with Wine. I reinstalled it then deleted Photoshop in my ApplicationData folder (Windows keeps user software options in this folder). None of these worked. I tried on my laptop and this strange problem exists there too.

• Copy diagram with swimlanes in Enterprise Architect

  - by blomqvist

  This is a post mostly to myself, so that when I forget this I can come here and check it out :) (I forget about ctrl-b from time to time) When copying diagrams from Enterprise Architect you can use ctrl-B to include the swim-lanes. A normal ctrl-c will not give you the swim-lanes. A side effect is that ctrl—b gives you a copy of the whole diagram, you cannot select what objects to copy. So marking objects first or pressing ctrl-A to selects all is both unnecessary and meaningless since ctrl-b seems to mean: “copy the whole diagram now and include all the stuff in there, even the swimlanes” (which ctrl-A, ctrl-C does not).

• Would you use UML if it kept stakeholders from requesting changes frequently?

  - by Huperniketes

  As much as programmers hate to document their code/system and draw UML (especially, Sequencing, Activity and State machine diagrams) or other diagramming notation, would you agree to do it if it kept managers from requesting a "minor change" every couple of weeks? IOW, would you put together visual models to document the system if it helped you demonstrate to managers what the effect of changes are and why it takes so long to implement them? (Edited to help programmers understand what type of answer I'm looking for.) 2nd edit: Restating my question again, "Would you be willing to use some diagramming notation, against your better nature as a programmer, if it helped you manage change requests?" This question isn't asking if there might be something wrong with the process. It's a given that there's something wrong with the process. Would you be willing to do more work to improve it?

• Can I force window to open on top of other windows when opened by keyboard shortcut?

  - by Rasmus

  I use SpaceFM as my primary file manager on Ubuntu. I typically open folder directly by keyboard shortcuts, so, e.g. Ctrl+Super+W opens my Work folder. Specifically, I use execute the command spacefm -w /home/rasmus/Work/ by the above shortcut, with the -w ensuring that SpaceFM opens a new window. However, this new window is not always open on top of the last active window on the workspace. This is rather annoying, as it means I sometimes have to "dig" for the newly opened window. So, my question is: Is there something additional I can add to the executed command that will ensure that the fresh window is opened on top? Alternative solutions to the same effect are welcome.

• Make Offscreen Sliding Content Without Hurting SEO [duplicate]

  - by etangins

  This question already has an answer here: How bad is it to use display: none in CSS? 5 answers On my website I have content which is positioned off the screen, and then slides in when you click a button. For example, when you click the news button, content slides in with news. It didn't occur to me that this might be labeled as a black hat SEO technique, because I have content positioned off the screen with CSS that links elsewhere on my site, and a search engine could very easily interpret that as me hiding content for SEO purposes by positioning it off screen. Obviously, my intention was not to hide content, but was to make a sort of UI/UX content slider where content slides into view when a button is clicked. How can I make something to this effect (where content slides in and out), that would not comprise SEO?
