• Game Patching Mac/PC

  - by Centurion Games

  Just wondering what types of solutions are available to handle patching of PC/Mac games that don't have any sort of auto updater built into them. In windows do you just spin off some sort of new install shield for the game that includes the updated files, hope you can read a valid registry key to point to the right directory, and overwrite files? If so how does that translate over to Mac where the game is normally just distributed as straight up .app file? Is there a better approach than the above for an already released product? (Assuming direct sells, and not through a marketplace that features auto-updating like Steam.) Are there any off the shelf auto-updater type libraries that could also be easily integrated with a C/C++ code base even after a game has been shipped to make this a lot simpler, and that are cross platform? Also how do auto-updaters work with new OS's that want applications and files digitally signed?

• Player sprite moving slower on iPhone 4

  - by nvillec

  I just finished getting movement/jump animation for a player sprite in Xcode using Cocos2D. The basic movement algorithm is a timer that updates every 0.01 sec, changing the sprite position to (sprite.position.x + xVel, sprite.position.y + yVel). Each time a movement button is tapped, the appropriate velocity (initialized to 0) is changed to whatever speed I choose, then a stop movement button returns the velocity to 0. It's not an ideal solution but I'm very new at this and stoked to at least have that working with little help from the internet. So I may not have explained that perfectly, but it is in fact working to my satisfaction in Xcode's iPhone Simulator, however when I build it for my device and run it on my phone, the sprite's movement speed is noticeably slower than in Xcode. At first I thought it must have to do with the resolution of the iPhone 4, making the sprite's movement path twice as long, but I found that if I pull up the multitask bar, then return to the app the speed will sometimes jump back to normal. My second theory was that the code is just inefficient and is bogging the processes down, but I would see this reflected in the frame rate wouldn't I? It stays at 59-60 the whole time, and the spritesheet animation runs at the correct speed. Has anyone experienced this? Is this a really obvious issue that I'm completely missing? Any help (or tips for optimizing my approach to movement) would be much appreciated!

• SDL mouse wheel not picking up

  - by Chris

  Running Ubuntu 11.04, SDL 1.2 trying to pickup mouse wheel up/down movement with this (stripped down) code: int main( int argc, char **argv ) { SDL_MouseButtonEvent *mousebutton = NULL; while ( !done ) { if(mousebutton != NULL && mousebutton->button == SDL_BUTTON_LEFT) yrot += 0.75f; else if(mousebutton != NULL && mousebutton->button == SDL_BUTTON_RIGHT) yrot -= 0.75f; else if(mousebutton != NULL && mousebutton->button == SDL_BUTTON_WHEELUP){ xrot += 0.75f; }else if(mousebutton != NULL && mousebutton->button == SDL_BUTTON_WHEELDOWN){ xrot -= 0.75f; } while ( SDL_PollEvent( &event ) ) { switch( event.type ) { case SDL_MOUSEBUTTONDOWN: mousebutton = &event.button; break; case SDL_MOUSEBUTTONUP: mousebutton = NULL; break; default: break; } } } return 0; } strange thing is, scrolling with the mouse button does nothing, but if I hold down a mouse button or two and then move the mouse it hits the SDL_BUTTON_WHEEL code occasionally. This honestly reeks of a pointer issue, which would make sense since I've been spoiled with C# for the past couple years, but I am just not seeing it. How do i correctly find mouse scroll events in SDL?

• andEngine dynamic sprites

  - by Blucreation

  Ive just started with andEngine the past week and i only started learning java/android 3 weeks. I can use a for loop to add multiple sprites to the screen but when i try to check collisions on them it only does it to one and not the rest. I want to be able to add a specific number for sprites made from the same texture to the scene, add collision detection to them and also make them slide across the screen (im making a game where you avoid the obstacles). My simple code: private void createobstacle(float pX, float pY) { obstacle = new AnimatedSprite(pX, pY, this.mObjTextureRegion.deepCopy(), getVertexBufferObjectManager()); obstacle.setScale(MathUtils.random(0.5f, 3f)); scene.attachChild(obstacle); } private void createobstacle(int num) { for(int i=0; i<=num; i++ ) { final float xPos = MathUtils.random(30.0f, (CAMERA_WIDTH - 30.0f)); final float yPos = MathUtils.random(30.0f, (CAMERA_HEIGHT - 30.0f)); createobstacle(xPos, yPos); } } Ive read about arrays but i cannot find any tutorials about anything im stuck with. Any help would be great!

• SFML title bar with weird characters when using UTF-8

  - by TheOm3ga

  (Previously asked at http://stackoverflow.com/questions/4922478/sfml-title-bar-with-weird-characters-when-using-utf-8) I've just started using SFML and one of the first problems I've come across is some weird characters on the the titlebar whenever I try to use accents or any other extended char. For instance, I've got: sf::RenderWindow Ventana(sf::VideoMode(800, 600, 32), "Año nuevóóó"); And the titlebar renders like AÂ+o nuevoA³A³A³ This ONLY HAPPENS if my source code file is enconded in UTF-8. If I change the file encoding to ISO-8859-1, it shows properly. Obviously all of my files use UTF-8, as its the system-wide encoding. I'm using GCC under Ubuntu GNU/Linux. I've tried using the different utilities in sf::Unicode to adapt the text, but none of them seems to work.

• Depth buffer values reset on change shader?

  - by bobobobo

  I have 2 different shaders, and when I change the shader (glUseProgram), it seems that the depth information is lost, because everything drawn with the 2nd shader appears completely on top of anything drawn by the first shader. If I switch the order of shader use/drawing, then it's the same (the last drawn object always appears on top of the first drawn object if there is a shader change between the 2 objects, even if the last drawn object is further away)

• Are there any open source projects for car engine sound simulation?

  - by Petteri Hietavirta

  I have been thinking how to create realistic sound for a car. The main sound is the engine, then all kind of wind, road and suspension sounds. Are there any open source projects for the engine sound simulation? Simply pitching up the sample does not sound too great. The ideal would be to something that allows me to pick type of the engine (i.e. inline-4 vs v-8), add extras like turbo/supercharger whine and finally set the load and rpm. Edit: Something like http://www.sonory.org/examples.html

• Writing a Master's Thesis on evaluating visual scripting systems

  - by user1107412

  I am thinking to write my Master's thesis around theorizing, and then implementing a PlayMaker or Kismet-like (building game logic by visually arranging FSMs) tool in Unity. The only thing I am still concerned about is the actual research question that I should pose. I was kinda hoping that the more experienced game designers out there might know. Update: What about reducing the use of visual programming to graphically designing FSM-Action-Transition flows, which can then be attached to game entities (very much like http://playmaker.com does it)?

• HLSL: An array of textures and sampler states

  - by nate142

  The shader must switch between multiple textures depending on the Alpha value of the original texture for each pixel. Now this would word fine if I didn't have to worry about SamplerStates. I have created my array of textures and can select a texture based on the Alpha value of the pixel. But how do I create an Array of SamplerStates and link it to my array of textures? I attempted to treat the SamplerState as a function by adding the (int i) but that didn't work. Also I can't use Texture.Sample since this is shader model 2.0. //shader model 2.0 (DX9) texture subTextures[255]; SamplerState MeshTextureSampler(int i) { Texture = (subTextures[i]); }; float4 SampleCompoundTexture(float2 texCoord, float4 diffuse) { float4 SelectedColor = SAMPLE_TEXTURE(Texture, texCoord); int i = SelectedColor.a; texture SelectedTx = subTextures[i]; return tex2D(MeshTextureSampler(i), texCoord) * diffuse; }

• Creating Gun objects with upgrades?

  - by zardon

  I have a series of guns in my game. I use the Gun class/object like this: (Just an example) @interface Gun : NSObject { NSString *name; // Six-shooter NSNumber *cost; NSNumber *clipPrice; // ie: 700 NSNumber *clipCapacity; // 6 NSNumber *ammoCapacity; // 6 NSNumber *damage; // 0-10 NSNumber *accuracy; // 0-10 NSNumber *fireRate; // 0-10 NSNumber *range; // 0-10 // Not sure if I have all the stats, but this is fine for now } Lets say I want to have 3 upgrades per gun. My problem is I am not sure how to do this. Examples: increase fire-rate increase range increase accuracy silencer double ammo capacity (ie: Drum) double clip capacity (ie: Taped magazine) Thus my question is, I'd like to implement an upgrade system to guns but I am not sure how to do it. Would there be an Upgrade object which is a child to the Gun class, or would it be seperate class altogether. Thanks for your time.

• how to modify shadow mapping in "3D Graphics with XNA Game Studio 4.0"?

  - by naprox

  So I've been following the tutorials from the book Sean James's "3D Graphics with XNA Game Studio 4.0", and have been doing fine until i reached the shadow mapping part. in this book it creates point lights with a Sphere model. my first Q is how to draw a directional Light with this frame work? secondly it can do shadow mapping just for one light, how can i do shadow mapping for all or parts of the lights in the game? i just want to know how to modify this codes to do the above tasks. I've followed tutorials on MSDN and some other sites and didn't got the answer. please help me, its so urgent. and if any one wants, the complete code is here: http://www.mediafire.com/?6ct11mc1g8f891h

• Collision Detection fails with AI cars

  - by amit.r007

  I am making a car parking game in flash and AS3 wherein I drive my car along with other AI traffic cars moving along a specified path using Guidelines. I am using CDK for collision detection. The collision detection works fine with few AI cars, but doesn't seems to be working as required for few AI cars. When an AI car is moving on a path in a straight line it works fine.... but when the AI Car turns at 90 degress..... my car goes into the AI car (Overlapping) and it hits at the center of that AI car and then collision is Detected.... ..... I made a New path and used a new Sprite for AI car... but still the problem pursues....

• Well-tested libraries for player ratings?

  - by Lucky

  It's common in games to implement some sort of numerical ranking system -- the ELO system is usually used in chess. I could implement this system naively using Wikipedia's descriptions, but I suspect that this would open up a whole box of problems that have already been solved: rating inflation, etc -- for instance, the ELO system has a K constant that's 'fudged' according to rating, duration, pairings, statistics, ... What are some libraries (I'm looking at Python, but anything is okay) that implements rating systems? It also doesn't have to be ELO.

• Design leaderboard ratings for quiz games

  - by PeterK

  Back in March 2011 i started the following post: How to design a leaderboard? Now my quiz game have been out for approximately a year and sold pretty decently. I am working on to update the game design and is again looking into the leaderboard design to make it better as i am not happy with it. Currently i rate players on number of correct answers, which is not good as it does not consider things like number of games, difficulty levels etc. I also have "extended" stats behind the UITableView (Leaderboard). A player can play based on three levels of difficulty: hard, medium or easy Difficulty levels can be mixed between players in a game Each game can be one to six players, so there can be single games or duels Between 2 and 30 questions per game As i am considering integrating Game Center Leaderboard i need to design a better rating system so i would like to ask for some ideas how to do the rating based on the above. I am thinking about how much a point would be worth and what it includes.

• Point Light Soft Shadows

  - by notabene

  How to implement soft shadows for omni directional (point) light. We use typical shadow mapping technique. Depth is rendered to texture cube and addresing is pretty simple then. Just using vector from light to fragments world position. It works perfectly. Until you want soft shadows. In our engine we use PCSS technique for spot lights. But for point light there begins troubles. How to sample in 3D? I developed technique when orthonormal basis is created from a direction and upvector (0,1,0). And then multiply sampling vector (something like this (1.0,i/depthMapSize,j/depthMapSize) with this basis. But this (of course :)) looks pretty bad for vectors near (0,1,0) and (0,-1,0). I will appreciate any help on this.

• Implementing invisible bones

  - by DeadMG

  I suddenly have the feeling that I have absolutely no idea how to implement invisible objects/bones. Right now, I use hardware instancing to store the world matrix of every bone in a vertex buffer, and then send them all to the pipeline. But when dealing with frustrum culling, or having them set to invisible by my simulation for other reasons, means that some of them will be randomly invisible. Does this mean I effectively need to re-fill the buffer from scratch every frame with only the visible unit's matrices? This seems to me like it would involve a lot of wasted bandwidth.

• Entity system in Lua, communication with C++ and level editor. Need advice.

  - by Notbad

  Hi!, I know this is a really difficult subject. I have been reading a lot this days about Entity systems, etc... And now I'm ready to ask some questions (if you don't mind answering them) because I'm really messed. First of all, I have a 2D basic editor written in Qt, and I'm in the process of adding entitiy edition. I want the editor to be able to receive RTTI information from entities to change properties, create some logic being able to link published events to published actions (Ex:A level activate event throws a door open action), etc... Because all of this I guess my entity system should be written in scripting, in my case Lua. In the other hand I want to use a component based design for my entities, and here starts my questions: 1) Should I define my componentes en C++? If I do this en C++ won't I loose all the RTTI information I want for my editor?. In the other hand, I use box2d for physics, if I define all my components in script won't it be a lot of work to expose third party libs to lua? 2) Where should I place the messa system for my game engine? Lua? C++?. I'm tempted to just have C++ object to behave as servers, offering services to lua business logic. Things like physics system, rendering system, input system, World class, etc... And for all the other things, lua. Creation/Composition of entities based on components, game logic, etc... Could anyone give any insight on how to accomplish this? And what aproach is better?. Thanks in advance, HexDump.

• How are these bullets done?

  - by Mike

  I really want to know how the bullets in Radiangames Inferno are done. The bullets seem like they are just billboard particles but I am curious about how their tails are implemented. They can curve so this means they are not just a billboard. Also, they appear continuous which implies that the tails are not made of a bunch of smaller particles (I think). Can anyone shead some light on this for me?

• What's the best way to compare blocks in a matching game that can be multiple colors?

  - by Ryan Detzel

  I have a match 3-4 game and the blocks can be one of 7 colors. There are an addition 7 blocks that are a mix of the original 7 colors so for example there is a red and blue block and there is also a red/blue block which can be matched with either the red or the blue. My original thought is just to use binary operations so. int red = 0x000000001; int blue = 0x000000010; int redblue = 0x000000011; Then just do an & operation so see if they match. Does this sound like a decent plan or am I over complicating it? edit: Better yet so it's more readable. int red = 1; int blue = 2; int red_blue = 3; int yellow = 4; int red_yellow = 5; maybe as defines or static vars?

• Best gui toolkit to use for creating 3D board game

  - by UserInteractive

  I have created a board game using Java and Swing - using GridLayout and various other apis. It works properly but the UI looks very very simple. I would want couple of animations like tilting the GridLayoutat any angle. There are pawns on boxes of the GridLayout that I want to be animated when somebody clicks on it. I'm not sure of the right GUI toolkit to use for this. Swing repaint is possible to a limit and cannot be used for a lot of animation and graphics. And I realized after creating the game that Swing is probably not a good tool to create games. Could anybody suggest a better framework to use that I can use it in Eclipse with Java? I was thinking of JavaFX or tools like Adobe Flash or Adobe Air. Any suggestions please?

• Game Input mouse filtering

  - by aaron

  I'm having a problem with filtering mouse inputs, the method I am doing right know moves the cursor back to the center of the screen each frame. But I cant do this because it messes with other things. Does anyone know how to implement this with delta mouse movement. Here is the relevant code. void update() { static float oldX = 0; static float oldY = 0; static float walkSpeed = .05f; static float sensitivity = 0.002f;//mouse sensitivity static float smooth = 0.7f;//mouse smoothing (0.0 - 0.99) float w = ScreenResolution.x/2.0f; float h = ScreenResolution.y/2.0f; Vec2f scrc(w,h); Vec2f mpos(getMouseX(),getMouseY()); float x = scrc.x-mpos.x; float y = scrc.y-mpos.y; oldX = (oldX*smooth + x*(1.0-smooth)); oldY = (oldY*smooth + y*(1.0-smooth)); x = oldX * sensitivity; y = oldY * sensitivity; camera->rotate(Vec3f(y,0,0)); transform->setRotation(transform->getRotation()*Quaternionf::fromAxisAngle(0.0f,1.0f,0.0f,-x)); setMousePosition((int)scrc.x,(int)scrc.y);//THIS IS THE PROBLEM LINE HOW CAN I AVOID THIS .... }

• Manually updating HTML5 local storage?

  - by hustlerinc

  I'm just starting out HTML5 game developement (and game dev in general) and watching all the videos and tutorials available something has crossed my mind. Everyone keep saying I should set the cookie's (or cached files) to be expired after a certain amount of time. So that when it reaches that time the browser automatically downloads all assets again, even if it's the same asset's. Wouldn't it be possible to manually define the version of the game? For example the user has downloaded all the files for 1.01 of the game, when updating I change a simple variable to 1.02. When the user logs in it would compare his version to the current and if they are not equal only then it downloads the files? This could even be improved to download only specific files depending on what needs to be updated? Would this be possible or am I just dreaming? What are the possible downsides of this approach?

• Why Swipe left doesn't work? [on hold]

  - by Hitesh

  I wrote the below code to detect and perform a sprite action on the single tap and swipe right event. @Override public boolean onSceneTouchEvent(Scene pScene, TouchEvent pSceneTouchEvent) { float x = 0F; int tapCount = 0; boolean playermoving = false; // TODO Auto-generated method stub if (pSceneTouchEvent.getAction() == MotionEvent.ACTION_MOVE) { if (pSceneTouchEvent.getX() > x) { playermoving = true; players.runRight(); } if (pSceneTouchEvent.getX() < x) { Log.i("Run Left", "SPRITE Left"); } /* * if (pSceneTouchEvent.getX() < x) { System.exit(0); * Log.i("SWIPE left", "SPRITE LEFT"); } */ } if (pSceneTouchEvent.getAction() == MotionEvent.ACTION_DOWN) { playermoving = false; x = pSceneTouchEvent.getX(); tapCount++; Log.i("X CORD", String.valueOf(x)); } if (pSceneTouchEvent.isActionDown()) { if (tapCount == 1 && playermoving != true) { tapCount = 0; players.jumpRight(); } } return true; } The code works fine. The only problem is that the swipe left event is not being detected due to some reasons. What can i do to make the swipe left action work? Please help

• Wheel Joint Implementation in AndEngine

  I am currently developing car game in AndEngine. In which I was using revolute joint for car wheel and chassis attachment. But my friend suggest me that use wheel joint for that purpose for better behavior of the car. In AndEnginen I didn't found the wheel joint implementation. So what I have to do for wheel joint implementation. I think I have to manually update the box2d library for this purpose but I don't know how many things get updated. Please suggest me some guidance on achieving better car behavior in AndEngine.

• What''s easy extensible technique to store game data?

  I'm looking for library/technique for storing my game resources - levels, object (effects,world info), items(price,effects,...), NPC(visual info, behavior), everything except graphics/audio stuff. I've seen lua used for Awesome WM configuration. protobuf looks good, but it seems to be designed for network communication. I've tried to write my own parser, but as the project grows it's more and more harder to manage it and catch all the bugs. My requiremets: stability easy extension of data without need to convert older versions to newer good(don't have to be the best) performance of loading not much coding not XML!
