• Broad topics needed for teaching game development

  - by livingtech

  I am going to be doing a presentation on game development to an iPhone user group in the near(ish) future. My audience are iPhone developers, but not necessarily very experienced ones, and this is meant to be an introduction. My question is, what broad topics are needed to understand game development? I acknowledge that this is fairly subjective, but I really am hoping for a comprehensive list of high-level topics that apply to a broad enough swath of games that anyone interested in the topic SHOULD know about them. I would be ecstatic with some pointers to any resources that attempt to make a list such as this this. (I have looked, but my google-fu is failing me tonight.) Here's what I have so far: The Game Loop a sub-note about event driven games 2D Animation sprites/texture maps 3D Animation importance of frameworks modeling software Particles and particle effects hit detection AI Obviously I will not be covering all these topics with any depth, more like simply defining them so that after my talk, the audience will (hopefully) be able to wrap their heads around how any given game might be developed. What am I missing?

• An alternative to a video codec for storing motion changes [on hold]

  - by Andrew Simpson

  I have a 3 dimensional byte array. The 3-d array represents a jpeg image. Each channel/array represents part of the RGB spectrum. I am not interested in retaining black pixels. A black pixel is represented by this atypical arrangement: myarray[0,0,0] =0; myarray[0,0,1] =0; myarray[0,0,2] =0; So, I have flattened this 3d array out to a 1d array by doing this byte[] AFlatArray = new byte[width x height x 3] and then assigning values respective to the coordinate. But like I said I do not want black pixels. So this array has to only contain color pixels with the x,y coordinate. The result I want is to re-represent the image from the i dimension byte array that only contains non-black pixels. How do I do that? It looks like I have to store black pixels as well because of the xy coordinate system. I have tried writing to a binary file but the size of that file is greater than the jpeg file as the jpeg file is compressed. I am using c#.

• The Fantastic New WebLogic on Oracle Database Appliance 2.9 Release is Here!

  - by JuergenKress

  Last week was a big day in virtualised ODA-land as it saw the launch of WebLogic on ODA 2.9. Admittedly it doesn't sound like a very exciting release but it is one that we at O-box have been looking forward to for quite some time. Let me explain why, then we'll look into the details... The ODA X4-2 has 48 Intel Xeon cores. That is a lot of compute power. Whilst the largest O-box SOA Appliance single environment configuration can in theory use all those cores (currently with 40 vCPU of SOA!) the vast majority of O-box users will want smaller configurations. Prior to 2.9 the Oracle WebLogic implementation only supported one domain per ODA, so the conundrum O-box development faced last year was either: offer customers only one SOA environment on their O-box for now (but have the benefit of a standard, easily supportable WebLogic installation), or build our own WebLogic/OTD OVM templates from scratch. One of our driving goals with O-box is to give the best possible experience and make the appliance as supportable as possible. Therefore we took the gamble that we would stick with the Oracle's one-domain WebLogic configuration initially, and just hope that it would deliver multi-domain support for us in a timely manner (note: this is probably not a strategy that business textbooks would recommend!). Anyway, we've been working closely with Oracle Product Management for a few months now and I'm delighted to see 2.9 as the fruits of their labour. This also neatly ties in with several recent requests for O-box to include OSB as well as SOA/BPEL (which we have always wanted to have in separate domains). The diagram below is the neatest way to summarise what the new 2.9 release will allow us to deliver, i.e. previously only one 3D box was possible: Read the complete article here.

• Space-efficient data structures for broad-phase collision detection

  - by Marian Ivanov

  As far as I know, these are three types of data structures that can be used for collision detection broadphase: Unsorted arrays: Check every object againist every object - O(n^2) time; O(log n) space. It's so slow, it's useless if n isn't really small. for (i=1;i<objects;i++){ for(j=0;j<i;j++) narrowPhase(i,j); }; Sorted arrays: Sort the objects, so that you get O(n^(2-1/k)) for k dimensions O(n^1.5) for 2d and O(n^1.67) for 3d and O(n) space. Assuming the space is 2D and sortedArray is sorted so that if the object begins in sortedArray[i] and another object ends at sortedArray[i-1]; they don't collide Heaps of stacks: Divide the objects between a heap of stacks, so that you only have to check the bucket, its children and its parents - O(n log n) time, but O(n^2) space. This is probably the most frequently used approach. Is there a way of having O(n log n) time with less space? When is it more efficient to use sorted arrays over heaps and vice versa?

• Sending changes to a terrain heightmap over UDP

  - by Floomi

  This is a more conceptual, thinking-out-loud question than a technical one. I have a 3D heightmapped terrain as part of a multiplayer RTS that I would like to terraform over a network. The terraforming will be done by units within the gameworld; the player will paint a "target heightmap" that they'd like the current terrain to resemble and units will deform towards that on their own (a la Perimeter). Given my terrain is 257x257 vertices, the naive approach of sending heights when they change will flood the bandwidth very quickly - updating a quarter of the terrain every second will hit ~66kB/s. This is clearly way too much. My next thought was to move to a brush-based system, where you send e.g. the centre of a circle, its radius, and some function defining the influence of the brush from the centre going outwards. But even with reliable UDP the "start" and "stop" messages could still be delayed. I guess I could compare timestamps and compensate for this, although it'd likely mean that clients would deform verts too much on their local simulations and then have to smooth them back to the correct heights. I could also send absolute vert heights in the "start" and "stop" messages to guarantee correct data on the clients. Alternatively I could treat brushes in a similar way to units, and do the standard position + velocity + client-side prediction jazz on them, with the added stipulation that they deform terrain within a certain radius around them. The server could then intermittently do a pass and send (a subset of) recently updated verts to clients as and when there's bandwidth to spare. Any other suggestions, or indications that I'm on the right (or wrong!) track with any of these ideas would be greatly appreciated.

• How AlphaBlend Blendstate works in XNA 4 when accumulighting light into a RenderTarget?

  - by cubrman

  I am using a Deferred Rendering engine from Catalin Zima's tutorial: His lighting shader returns the color of the light in the rgb channels and the specular component in the alpha channel. Here is how light gets accumulated: Game.GraphicsDevice.SetRenderTarget(LightRT); Game.GraphicsDevice.Clear(Color.Transparent); Game.GraphicsDevice.BlendState = BlendState.AlphaBlend; // Continuously draw 3d spheres with lighting pixel shader. ... Game.GraphicsDevice.BlendState = BlendState.Opaque; MSDN states that AlphaBlend field of the BlendState class uses the next formula for alphablending: (source × Blend.SourceAlpha) + (destination × Blend.InvSourceAlpha), where "source" is the color of the pixel returned by the shader and "destination" is the color of the pixel in the rendertarget. My question is why do my colors are accumulated correctly in the Light rendertarget even when the new pixels' alphas equal zero? As a quick sanity check I ran the following code in the light's pixel shader: float specularLight = 0; float4 light4 = attenuation * lightIntensity * float4(diffuseLight.rgb,specularLight); if (light4.a == 0) light4 = 0; return light4; This prevents lighting from getting accumulated and, subsequently, drawn on the screen. But when I do the following: float specularLight = 0; float4 light4 = attenuation * lightIntensity * float4(diffuseLight.rgb,specularLight); return light4; The light is accumulated and drawn exactly where it needs to be. What am I missing? According to the formula above: (source x 0) + (destination x 1) should equal destination, so the "LightRT" rendertarget must not change when I draw light spheres into it! It feels like the GPU is using the Additive blend instead: (source × Blend.One) + (destination × Blend.One)

• Cocos2d/Cocos2d-x Attaching an arrow (sprite) to another body sprite (person)

  - by Satchmo Brown

  I am trying to set up a simple bow and arrow game. When the arrow hits the enemy body, the arrow's body is deleted and the arrow sprite continues to update, keeping the position correct in relation to the enemy it hit. Picture an arrow sticking into a body and that body still rotating and moving. My problem is that the rotation is completely wrong when the enemy rotates. I know how to do this in 3d with matrix transformation but I can't seem to figure it out in 2d with Cocos. Here is my method. I save offset at which the arrow hit the enemy. Every frame, I make the rotation of the sprite match the rotation of the enemy. Then, I apply the offset I took initially which is where the arrow hit the enemy. When they rotate, they rotate about their respective anchors and I am wondering if I need to set the anchor of the arrow to the center of the sprite. Does anyone know of an easy way to do this. If not, I will try to create an algorithm where the anchor is set to the offset divided by the width and height of the sprite image hopefully giving me the correct anchor values. Then I assume I need to reposition the sprite. Does anyone have a simpler way to do this?

• What's a good entity hierarchy for a 2D game?

  - by futlib

  I'm in the process of building a new 2D game out of some code I wrote a while ago. The object hierarchy for entities is like this: Scene (e.g. MainMenu): Contains multiple entities and delegates update()/draw() to each Entity: Base class for all things in a scene (e.g. MenuItem or Alien) Sprite: Base class for all entities that just draw a texture, i.e. don't have their own drawing logic Does it make sense to split up entities and sprites up like that? I think in a 2D game, the terms entity and sprite are somewhat synonymous, right? But I do believe that I need some base class for entities that just draw a texture, as opposed to drawing themselves, to avoid duplication. Most entities are like that. One weird case is my Text class: It derives from Sprite, which accepts either the path of an image or an already loaded texture in its constructor. Text loads a texture in its constructor and passes that to Sprite. Can you outline a design that makes more sense? Or point me to a good object-oriented reference code base for a 2D game? I could only find 3D engine code bases of decent code quality, e.g. Doom 3 and HPL1Engine.

• XNA calculate normals for linesegment

  - by Gerhman

  I am quite new to 3D graphical programming and thus far only understand that normal somehow define the direction in which a vertex faces and therefore the direction in which light is reflected. I have now idea how they are calculated though, only that they are defined by a Vector3. For a visualizer that I am creating I am importing a bunch of coordinate which represent layer upon layer of line segments. At the moment I am only using a vertex buffer and adding the start and end point of each line and then rendering a linelist. The thing is now that I need to calculate the normal for the vertices of these line segments so that I can get some realistic lighting. I have no idea how to calculate these normal but I know they all face sideways and not up or down. To calculate them all I have are the start and end positions of each line segment. The below image is a representation of what I think I need to do in the case of an example layer: The red arrows represent the normal that should be calculates, the blue text represent the coordinates of the vertices and the green numbers represent their indices. I would greatly appreciate it if someone could please explain to me how I should calculate these normal.

• XNA Skinned Animated Mesh Rendering Exported from Maya

  - by Devin Garner

  I am working on translating an old RTS game engine I wrote from DirectX9 to XNA. My old models didn't have animation & are an old format, so I'm trying with an FBX file. I temporarily "borrowed" a model from League of Legends just to test if my rendering is working correctly. I imported the mesh/bones/skin/animation into Maya 2012 using an "unnamed" 3rd-party import tool. (obviously I'll have to get legit models later, but I just want to test if my programming is correct). Everything looks correct in maya and it renders the animations flawlessly. I exported everything into a single FBX file (with only a single animation). I then tried to load this model using the example at the following site: http://create.msdn.com/en-US/education/catalog/sample/skinned_model With my exported FBX, the animation looks correct for most of the frames, however at random times it screws up for a split second. Basically, the body/arms/head will look right, but the leg/foot will shoot out to a random point in space for a second & then go back to the normal position. The original FBX from the sample looks correct in my program. It seems odd that my model was imported into maya wrong, since it displays fine in Maya. So, I'm thinking either I'm exporting it wrong, or the sample code is bad & the model from the sample caters to the samples bad code. I'm new to 3D programming & maya, so chances are I'm doing something wrong in the export. I'm using mostly the defaults, but I've tried all 3 interpolation modes (quaternion, euler, resample). Thanks

• Compiz slow under proprietary nvidia driver

  - by gsedej

  Hi! I am using Ubuntu 10.10 and have problem with proprietary nvidia driver for my GeForce GTS 250. I have issue with poor Compiz performance. And there is also open-source "noueau" driver. Proprietary: I tried many versions but neither works fast on desktop. This means 30 FPS without heavy effects. Currently I am using version 270.18. Even normal desktop use feels bad (moving windows) In games (and 3D benchmark) it is really good! (Unigine Heaven works good!) Open-source "nouveau": Very fast on desktop with heavy effects (blur, ...). I have 300 FPS and more, even in Expo mode. Games were good but not as good as prop. And driver causes xorg to crash even the latest (ppa:xorg-edgers/nouveau), so I switched back to proprietary. I also have computer with Ubuntu 10.04, GeForce 8600GT and drivers around 185.x and Compiz works great there. There is similar question Nvidia proprietary driver performance in 10.10 Which version of nvidia (prop) driver is fast in Compiz in Ubuntu 10.10? How do you install a specific version of nvidia driver? Is it the case that each newer driver works slower on compiz?

• How do I get the correct values from glReadPixels in OpenGL 3.0?

  - by NoobScratcher

  I'm currently trying to Implement mouse selection into my game editor and I ran into a little problem when I look at the values stored in &pixel[0],&pixel[1],&pixel[2],&pixel[3]; I get r: 0 g: 0 b: 0 a: 0 As you can see I'm not able to get the correct values from glReadPixels(); My 3D models are red colored using glColor3f(255,0,0); I was hoping someone could help me figure this out. Here is the source code: case WM_LBUTTONDOWN: { GetCursorPos(&pos); ScreenToClient(hwnd, &pos); GLenum err = glGetError(); while (glGetError() != GL_NO_ERROR) {cerr << err << endl;} glReadPixels(pos.x, SCREEN_HEIGHT - 1 - pos.y, 1, 1, GL_RGB, GL_UNSIGNED_BYTE, &pixel[0] ); cerr << "r: "<< (int)pixel[0] << endl; cerr << "g: "<< (int)pixel[1] << endl; cerr << "b: "<< (int)pixel[2] << endl; cerr << "a: "<< (int)pixel[3] << endl; cout << pos.x << endl; cout << pos.y << endl; } break; I use : WIN32 API OPENGL 3.0 C++

• Flickering when accessing texture by offset

  - by TravisG

  I have this simple compute shader that basically just takes the input from one image and writes it to another. Both images are 128/128/128 in size and glDispatchCompute is called with (128/8,128/8,128/8). The source images are cleared to 0 before this compute shader is executed, so no undefined values should be floating around in there. (I have the appropriate memory barrier on the C++ side set before the 3D texture is accessed). This version works fine: #version 430 layout (location = 0, rgba16f) uniform image3D ping; layout (location = 1, rgba16f) uniform image3D pong; layout (local_size_x = 8, local_size_y = 8, local_size_z = 8) in; void main() { ivec3 sampleCoord = gl_GlobalInvocationID.xyz; imageStore(pong, imageLoad(ping,sampleCoord)); } Reading values from pong shows that it's just a copy, as intended. However, when I load data from ping with an offset: #version 430 layout (location = 0, rgba16f) uniform image3D ping; layout (location = 1, rgba16f) uniform image3D pong; layout (local_size_x = 8, local_size_y = 8, local_size_z = 8) in; void main() { ivec3 sampleCoord = gl_GlobalInvocationID.xyz; imageStore(pong, imageLoad(ping,sampleCoord+ivec3(1,0,0))); } The data that is written to pong seems to depend on the order of execution of the threads within the work groups, which makes no sense to me. When reading from the pong texture, visible flickering occurs in some spots on the texture. What am I doing wrong here?

• Can anyone recommend an AI sandbox?

  - by user19433

  I'm passionate person, who has been around AI from a long time [1] but never going in deep enough. Now it's time! I've been really looking for some way to concentrate on AI coding but couldn't succeeded to find an AI environment I can focus on. I just want to use an AI sandbox environment which would let me have tools like: visibility information character controller able to easily define a level, with obstacles of course physics collider management triggers management don't need to be a shiny, eye candy graphical render : this is about pathfinding, tactical reasoning, etc.. I have tried : Unreal Dev Kit : while the new release announce is about C++ coding, this is about external tools and will be released in 2013 Cry Engine : really interesting as AI is presents here but coding with it appears to be an hell: did I got it wrong ? Half Life source, C4, Torque, Dx Studio : either quite old, not very useful or costly these imply to dig in documentation (when provided) to code everything, graphics included. Unity 3D : the most promising platform. While you also need to create your own environment, there are lot of examples. The disadvantage is, in addition to spend time to have this env. working, is the languages choice : C#, Javascript or Boo. C# is not that hard, but this implies you'll allways have to convert papers (I love those from Lars Linden) books codes, or anything you can have in Aigamedev are most often in C++. This is extra work. I've look at "Simple Path", the very good Arong Greenberg work but no source provided and AngryAnt work. AI Sandbox : this seems to be exactly what as AI coder I want to use. I saw some preview but from 2009 we still don't know what it will be about precisely, will it be opensource or free (I strongly doubt), will I be able to buy it? will it really provide me tools I need to focus on AI ? That being said, what is the best environment to be able to focus on AI coding only, is it even possible?

• How to use Pixel Bender (pbj) in ActionScript3 on large Vectors to make fast calculations?

  - by Arthur Wulf White

  Remember my old question: 2d game view camera zoom, rotation & offset using 'Filter' / 'Shader' processing? I figured I could use a Pixel Bender Shader to do the computation for any large group of elements in a game to save on processing time. At least it's a theory worth checking. I also read this question: Pass large array to pixel shader Which I'm guessing is about accomplishing the same thing in a different language. I read this tutorial: http://unitzeroone.com/blog/2009/03/18/flash-10-massive-amounts-of-3d-particles-with-alchemy-source-included/ I am attempting to do some tests. Here is some of the code: private const SIZE : int = Math.pow(10, 5); private var testVectorNum : Vector.<Number>; private function testShader():void { shader.data.ab.value = [1.0, 8.0]; shader.data.src.input = testVectorNum; shader.data.src.width = SIZE/400; shader.data.src.height = 100; shaderJob = new ShaderJob(shader, testVectorNum, SIZE / 4, 1); var time : int = getTimer(), i : int = 0; shaderJob.start(true); trace("TEST1 : ", getTimer() - time); } The problem is that I keep getting a error saying: [Fault] exception, information=Error: Error #1000: The system is out of memory. Update: I managed to partially workaround the problem by converting the vector into bitmapData: (Using this technique I still get a speed boost of 3x using Pixel Bender) private function testShader():void { shader.data.ab.value = [1.0, 8.0]; var time : int = getTimer(), i : int = 0; testBitmapData.setVector(testBitmapData.rect, testVectorInt); shader.data.src.input = testBitmapData; shaderJob = new ShaderJob(shader, testBitmapData); shaderJob.start(true); testVectorInt = testBitmapData.getVector(testBitmapData.rect); trace("TEST1 : ", getTimer() - time); }

• Dealing with 2D pixel shaders and SpriteBatches in XNA 4.0 component-object game engine?

  - by DaveStance

  I've got a bit of experience with shaders in general, having implemented a couple, very simple, 3D fragment and vertex shaders in OpenGL/WebGL in the past. Currently, I'm working on a 2D game engine in XNA 4.0 and I'm struggling with the process of integrating per-object and full-scene shaders in my current architecture. I'm using a component-entity design, wherein my "Entities" are merely collections of components that are acted upon by discreet system managers (SpatialProvider, SceneProvider, etc). In the context of this question, my draw call looks something like this: SceneProvider::Draw(GameTime) calls... ComponentManager::Draw(GameTime, SpriteBatch) which calls (on each drawable component) DrawnComponent::Draw(GameTime, SpriteBatch) The SpriteBatch is set up, with the default SpriteBatch shader, in the SceneProvider class just before it tells the ComponentManager to start rendering the scene. From my understanding, if a component needs to use a special shader to draw itself, it must do the following when it's Draw(GameTime, SpriteBatch) method is invoked: public void Draw(GameTime gameTime, SpriteBatch spriteBatch) { spriteBatch.End(); spriteBatch.Begin(SpriteSortMode.Immediate, BlendState.AlphaBlend, null, null, null, EffectShader, ViewMatrix); // Draw things here that are shaded by the "EffectShader." spriteBatch.End(); spriteBatch.Begin(/* same settings that were set by SceneProvider to ensure the rest of the scene is rendered normally */); } My question is, having been told that numerous calls to SpriteBatch.Begin() and SpriteBatch.End() within a single frame was terrible for performance, is there a better way to do this? Is there a way to instruct the currently running SpriteBatch to simply change the Effect shader it is using for this particular draw call and then switch it back before the function ends?

• Kids and programming: ScratchKara

  - by Mike Pagel

  Ever now and then I kept wondering how to share with my kids the excitement of creating something with your computer. Of course, today this is a bit more difficult, as they have seen 3D animation games and well-edited websites. I guess that's why they weren't all that hyped when I found my first computer model at our local recycling facilities (an 8-bit Laser VZ-200 with rubber keys). When I finally got it up and running with an old analog TV set they finally asked whether we could play soccer on it. Needless to say that my showing them how it remembers some BASIC commands and lists and executes them did not make any impression. So the question is for real: How do you get today's kids excited about programming? And just recently I looked again for environments that allow even young kids (mine are 7 and 9 years old now) to do something and have fun. Obviously any real, text-oriented programming language wouldn't work well. To cut it short: Something really nice was built by University of Oldenburg: ScratchKara. It is the perfect mixture of Kara, a simulation of a little ladybug and Scratch, an authoring environment from MIT. ScratchKara allows kids to initially simply explore how the bug moves and turns by pressing the action buttons, then move towards sequencing commands through drag & drop, and eventually end up building algorithms with procedures and functions. Even through it is built for kids and beginners, the environment comes with debugging and refactoring, which I found more than amazing. My kids love it and I have to admit I keep thinking about how to solve a bit more advanced problems with this language, which does not allow you to store any state information (other than your call stack). Yes, I am hooked, too... Once the language is understood you can then move to one of the original Kara versions, where you can define the bug's behavior through finite statemachines, Turing tables, Java and other textual languages. And from there, anything is possible.

• C Programming matrix

  - by Bilal Khan

  In this program the user enters the # of columns of the matrix and then the entries of the matrix. So, for example, if the user enters 2 for column # and 1 2 3 4 for entries then the program develops a 2 by 2 matrix with 1 2 3 4 as entries. My program works perfectly in such a case. However, if the user for example had only entered 1 2 3 then my program makes a matrix with garbage values. I would like the program in such a case to exit the program. It is a simple question, but it has me baffled. #include<stdio.h> #include<stdlib.h> int main() { int m,x, n, c = 0, d,k, matrix[10][10], transpose[10][10], product[10][10]; printf("Enter the number of columns of matrix "); scanf("%d",&m); if(m<=0){ printf("You entered a invalid value."); exit(0); } else{ printf("Enter the elements of matrix \n"); for( c = 0 ; c < 10 ; c++ ) { for( d = 0 ; d < m ; d++ ) { scanf("%d",&matrix[c][d]); if (matrix[c][d] == 99) // 'x' is character variable I declared to use as a break break; // c = c+1; } if (matrix[c][d] == 99) break; } } printf("\nHere is your matrix:\n"); int i; for(i=0;i<c;i++) { for(d=0;d<m;d++) { printf("%3d ",matrix[i][d]); } printf("\n"); }

• What is the best type of c# timer to use with an Unity game that uses many timers simultaneously?

  - by Kyle Seidlitz

  I am developing a stand-alone 3d game in Unity that will have anywhere from 1 to 200 timers running simultaneously. For this game timer durations will range from 5 minutes to 4 days. There will not be any countdown displays or any UI for the timers. An object will be selected, a menu choice will then be selected, and the timer will start. Several events will occur at different intervals during the duration of the timer. The events will be confined to changing the material of the selected object, and calling a 1 second sound effect like a chime or a bell. If the user wants to save or end the game before all the timers are done, the start of the still running timers is to be saved to an XML file such that when the game is started again, any still running timers will have a calculation done to see if the timer is then done, where the game will change the materials appropriately. I am still trying to figure out what type of timer to use, and see also if there are any suggestions for saving and calculating times over several days. What class(es) of timers should I use? Are there any special issues I should look out for in terms of performance?

• Is ActionScript 3 used by Serious Indie Developers?

  - by Puedes

  This question is for dedicated independent game developers: My dream is to be a game developer. I am a senior in high school who has taken Computer Science for all four years. I have used Java the whole time, but last year I started using PHP and ActionScript 3 (with Flixel). I also used Game Maker for a brief period. I apologize for this, I wanted to get that out of the way and clarify the fact that I have experience of some kind with game development. I am stuck at the moment because I don't quite know what language to use to develop games at a professional level. I am seriously interested in becoming a dedicated game developer, but this issue is really bothering me. I would like to know what the best option would be for my case, based on your experiences. Any advice is appreciated. Things to consider: I am only interested in making 2D games (I am not worried about 3D support) It would be ideal to use something that can be ported to multiple platforms (so as not to run into this problem later) I can't seem to figure out what the industry likes to use So far, this is what I have: I can't decide if it would be wise to stick with ActionScript 3, or move to C++ I know Flash would be for browser games, but what if I want to make a downloadable game, like Plants Vs. Zombies or Super Crate Box? Would Flash be a smart choice for standalone games, or did they use something else? Thank you for reading this, as I would like to stop worrying about this and make some games! Also, I hope this wasn't all over the place :) tl;dr Should I move ahead with AS3 or use something else i.e. C++

• Missing driver ASUS PCE-N53 11n N600 PCI-E Adapter

• Laggy Graphics After Upgrade to Ubuntu 13.10

  - by John bracciano

  I noticed some issues concerning the graphics after I upgraded from Ubuntu 13.04 to 13.10. More specifically: Dash tends to be more "laggy" than it used to be. When I switch desktops you can clearly see the screen going frame by frame. Menu bar is also "laggy". When I open GIMP, the menu bar is useless after a while - it takes seconds to refresh. The problems seem to appear after some seconds of use. When I boot the system everything works fine, until some more graphics-intensive program starts (Firefox, GIMP, etc). /usr/lib/nux/unity_support_test -p reports: OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Mobile OpenGL version string: 3.0 Mesa 9.2.1 Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: yes I use an Asus Zenbook UX31A with: Intel® Core i5 Ivy Bridge Integrated Intel® HD Graphics 4000 Intel® HM76 Express Chipset Thank you in advance for any answer!

• How do I re-enable the backlight?

  - by Scott Severance

  Since Oneiric, if I leave my machine (HP Mini 110 netbook) unattended and it goes into power-save mode, the backlight gets disabled. How can I turn it back on? Note that the keyboard backlight controls (Fn+F4 and Fn+F3) don't have any effect in this situation. I've already filed a bug, but filing a bug doesn't fix my problem. I tried this workaround posted in this bug report dealing with Acer laptops: sudo setpci -s 00:02.0 F4.B=0 However, if anything, that command makes things worse. In the general case, I can see a little bit if I'm in a dark room with a flashlight aimed just so. But after running setpci I can't see anything. And I find the setpci documentation to be utterly incomprehensible, so I don't know whether I need to tweak my command somehow or whether I'm completely barking up the wrong tree. Update: I've found a workaround: I'm now booting with the kernel parameter acpi=off. This disables power management, which prevents the machine from going into power saving mode and thus failing to come back up correctly. Of course, not having power management means that I can't use suspend or do anything to manage power other than powering it off (even then, I have to manually use the power switch). Also, it prevents me from using Unity 3D or Gnome Shell, forcing me into Unity 2C or Gnome Classic. So, I'd really like to be able to stop using this hack.
