• Parent variable inheritance methods Unity3D/C#

  - by Timothy Williams

  I'm creating a system where there is a base "Hero" class and each hero inherits from that with their own stats and abilities. What I'm wondering is, how could I call a variable from one of the child scripts in the parent script (something like maxMP = MP) or call a function in a parent class that is specified in each child class (in the parent update is alarms() in the child classes alarms() is specified to do something.) Is this possible at all? Or not? Thanks.

• What does SetTextureStage(0, D3DTSS_COLORARG2, 0) in DirectX mean?

  - by Vite Falcon

  I'm trying to convert some DirectX code to Ogre3D and was wondering what the following translates to: pDev->SetTextureStage(0, D3DTSS_TEXCOORDINDEX, 0) pDev->SetTextureStage(0, D3DTSS_COLORARG1, D3DTA_TEXTURE) pDev->SetTextureStage(0, D3DTSS_COLOROP, D3DTOP_MODULATE) pDev->SetTextureStage(0, D3DTSS_COLORARG2, 0) What is the modulation operation happening here? Is the texture getting modulated with the background? Or is it getting zeroed? I've tried searching for what this means and unfortunately I haven't come across anything meaningful. Any help to shed light on this matter will be much appreciated.

• filesystem types for partitions

  - by Tim

  I am going to dual-boot install Ubuntu1 10.04 on my laptop with Windows 7. I was wondering what filesystem types (such as ext2, ext3, ext4, ReiserFS and whatever might come into mind) are recommended for various possible partitions (such as /, home, /boot, swap, and others that might come into mind)and why? if ext4 is now stable enough for use for partitions in Ubuntu and Shared partition between Windows and Ubuntu? what journaling Options (writeback, ordered and journal) are recommended for each partition's filesystem? Thanks and regards!

• LibreOffice and HUD

  - by Dustin

  So I have tried out a couple daily builds and beta 1, and love HUD. However, currently LibreOffice does not play nice with HUD and I was wondering if there was a way to make it work with HUD. Kinda like the lo-menubar that applies the menu bar to the global menu, if there was means to get LibreOffice to work with HUD. Or might this question be too soon for an answer? Thank you for your time and answers.

  - by Roberto Giardina

  I am wondering if it is possible to change the number of entries in the list which appears when in Firefox you right click on a tab and choose "add to bookmarks" Thats because I use to categorize a lot of bookmarks and the standard choice of 5 entries is too small. Of course the idea is to not have to click on "choose" further down following the menu Thanks in advance and this is a really fantastic Website for Ubuntu users cheers Roberto

• Why did the old 3D games have "jittery" graphics?

  - by dreta

  I've been playing MediEvil lately and it got me wondering, what causes some of the old 3D games have "flowing" graphics when moving? It's present in games like Final Fantasy VII, MediEvil, i remember Dungeon Keeper 2 having the same thing in zoom mode, however f.e. Quake 2 didn't have this "issue" and it's just as old. The resolution doesn't seem to be the problem, everything is rendered perfectly fine when you stand still. So is the game refreshing slowly or it's something to do with buffering?

• SharpDX/D3D: How to implement and draw fonts/text

  - by Dmitrij A

  I am playing with SharpDX (Direct3D for .NET) without using "Toolkit", already finished with basic rendering 3D models. But now i am wondering how to program/create fonts for game (2D), or how to simple draw variable text to output with Direct3D? (it is not as SharpDX question as common Direct3D question, how to start with game GUIs? And what should i do to program simple GUI's like menu for a game (generally i understand that it's shaders).

• What features does D3D have that OpenGL does not (and vice versa)?

  - by Tom

  Are there any feature comparisons on Direct3D 11 and the newest OpenGL versions? Well, simply put, Direct3D 11 introduced three main features (taken from Wikipedia): Tesselation Multithreaded rendering Compute shaders Increased texture cache Now I'm wondering, how does the newest versions of OpenGL cope with these features? And since I have this feeling that there are features that Direct3D lacks from OpenGL's side, what are those?

• Ensuring that saved data has not been edited in a game with both offline and online components

  - by Omar Kooheji

  I'm in the pre-planning phase of coming up with a game design and I was wondering if there was a sensible way to stop people from editing saves in a game with offline and online components. The offline component would allow the player to play through the game and the online component would allow them to play against other players, so I would need to make sure that people hadn't edited the source code/save files while offline to gain an advantage while online. Game likely to be developed in either .Net or Java, both of which are unfortunately easy to decompile.

• Displaying performance data per engine subsystem

  - by liortal

  Our game (Android based) traces how long it takes to do the world logic updates, and how long it takes to a render a frame to the device screen. These traces are collected every frame, and displayed at a constant interval (currently every 1 second). I've seen games where on-screen data of various engine subsystems is displayed, with the time they consume (either in text) or as horizontal colored bars. I am wondering how to implement such a feature?

• loading 3d model data into buffers

  - by mulletdevil

  I am using assimp to load 3d model data. I have noticed that each loaded model is made up of different meshes. I was wondering should each mesh have it's own vertex/index buffer or should there just be one for the whole model? From looking through the index data that is loaded it seems to suggest that I will need a vertex buffer per mesh but I'm not 100% sure. I am using C++ and DirectX9 Thank you, Mark

• What is the usage of Spaly Trees in the real world?

  - by Meena

  I decided to learn about Balance search trees, so I picked 2-3-4 and splay trees. I'm wondering what are the examples of splay trees usage in the real world? In this Cornell: http://www.cs.cornell.edu/courses/cs3110/2009fa/recitations/rec-splay.html I read that splay trees are 'A good example is a network router'. But from rest of the explanation seams like network routers use hash tables and not splay trees since the lookup time is constant instead of O(log n). thanks!

• Can anyone tell me how to get the same Gnome desktop environment as the one in the photo?

  - by Elysium

  I have been using gnome fallback for more than a year, but recently I have come across this image: However, when in virtual machine (new copy of ubuntu 12.04) I change to gnome 3 shell, the desktop is not even similar to the one in the photo above. I am wondering if there are others things that I am missing/have to do....to get to the same thing (or similar) that you can see in the image above. NOTE: Here is a screenshot from the virtual machine after I used these commands: sudo add-apt-repository ppa:gnome3-team/gnome3 sudo apt-get update sudo apt-get install gnome-shell

• Getting user generated content with no titles to rank

  - by hugo

  We are creating a site that allows users to generate content. The user is provided with a text field only (no title), similar to Twitter, Facebook, and Google+. Each piece of content created by the users will have a dedicated page/URL. Since the page has no title, I was wondering how search engines will index and display our pages. If the content was shared on other social networks, what will those results look like if there is no title for the open graph or Twitter tags?

• Building general programming skills?

  - by toleero

  Hello :) I currently am quite new to programming, I've had exposure to a few languages (C#, PHP, JavaScript, VB, and some others) and I'm quite new to OOP. I was just wondering what is the best way to build up general programming/problem solving skills without being language specific? I was thinking maybe of something like Project Euler but more geared towards newbies? Thanks! Edit: I am looking at getting into Game Scripting/Programming, I'm already in Games but in a different discipline :)

• How do you author code

  - by garbagecollector

  This is something I was never taught. I have seen alot of different types of authoring styles. I code primarily in Java and Python. I was wondering if there was a standard authoring style or if everything is freestyle. Also if you answer would you mind attaching the style you use to author files that your create at home or at work. I usually just go @author garbagecollector @company garbage inc.

• What is the most performant CSS property for transitioning an element?

  - by Ian Kuca

  I'm wondering whether there is a performance difference between using different CSS properties to translate an element. Some properties fit different situations differently. You can translate an element with following properties: transform, top/left/right/bottom and margin-top/left/right/bottom In the case where you do not utilize the transition CSS property for the translation but use some form of a timer (setTimeout, requestAnimationFrame or setImmediate) or raw events, which is the most performant–which is going to make for higher FPS rates?

• Are there any preexisting maps for a Minecraft-like level I could use in my engine?

  - by Rishav Sharan

  I am working on a tiny cube-based engine like Minecraft. I was wondering if there is a way for me to get large blocky terrain in a text format that I can use for rendering on my engine? I don't want to start on procedural generation now, I just want a resource where I can get the coord list for a pretty looking terrain. Alternatively, is it possible for me to parse the Minecraft world files and use that data to generate terrain/buildings in my code?
