• Updates for IOS AppStore Multiplayer Game

  - by TobiHeidi

  I am developing a multiplayer game for the web, android and ios. For the web and android i can instantly push out new versions of my game because they support executing remotly loaded code. But with IOS i need to wait for an Apple approval taking about 10 days. I want to push updates more then weekly. What if my server code changes so the client MUST update? Run an old version of the server code just for IOS? How do other multiplayer devs handle this ?

• Numbers not adding up? (What am I not understanding here?) [closed]

  - by Milo

  I have the following output: Short version: The last numbers on the S= lines increase by H and SHOULD theoretically be linearly decreasing, ex: -285,-290,-295...but the fourth one jumps to -252. Yet, every other number is linearly increasing. Why is that and how could I fix that? To explain the numbers, it comes from slider value changed. I have a slider whose value is used to generate the float on the next line. Everything should be growing linearly here. This value is used to determine the size of a flow layout and it is also used in conjunction with a scrollbar. But basically I have a background for the flow layout and that number is the start location for rendering it. The numbers should linearly change to create a smooth transition but when that one jumps, it looks weird on screen and I dont understand why the numbers are jumping every X slider value changes. Mathematically what could be causing this? Here is the code for rendering the background and the function that is called when value changes: void LobbyTableManager::renderBG( GraphicsContext* g, agui::Rectangle& absRect, agui::Rectangle& childRect ) { float scale = 0.35f; int w = m_bgSprite->getWidth() * getTableScale() * scale; int h = m_bgSprite->getHeight() * getTableScale() * scale; int numX = ceil(absRect.getWidth() / (float)w) + 2; int numY = ceil(absRect.getHeight() / (float)h) + 2; int startY = childRect.getY(); int numAttempts = 0; while(startY + h < absRect.getY() && numAttempts < 1000) { startY += h; if(moo) { std::cout << startY << ","; } numAttempts++; } g->holdDrawing(); for(int i = 0; i < numX; ++i) { for(int j = 0; j < numY; ++j) { g->drawScaledSprite(m_bgSprite,0,0,m_bgSprite->getWidth(),m_bgSprite->getHeight(), absRect.getX() + (i * w) + (offsetX),absRect.getY() + (j * h) + startY,w,h,0); } } g->unholdDrawing(); g->setClippingRect(cx,cy,cw,ch); } void LobbyTableManager::setTableScale( float scale ) { scale += 0.3f; scale *= 2.0f; float scrollRel = m_vScroll->getRelativeValue(); setScale(scale); rescaleTables(); resizeFlow(); updateScrollBars(); float newVal = scrollRel * m_vScroll->getMaxValue(); m_vScroll->setValue(newVal); } void LobbyTableManager::valueChanged( agui::VScrollBar* source,int val ) { m_flow->setLocation(0,-val); } Any insight on mathematically why the anomaly might happen every Nth time would be helpful. I just dont understand why if every number linearly increates it jumps from -295 to -252! Thanks

• Profiling and containing memory per system

  - by chadb

  I have been interesting in profiling and keeping a managed memory pool for each subsystem, so I could get statistic on how much memory was being used in something such as sounds or graphics. However, what is the best design for doing this? I was thinking of using multiple allocators and just using one per subsystem, however, that would result in global variables for my allocators (or so it would seem to me). Another approach I have seen/been suggested is to just overload new and pass in an allocator for a parameter. I had a similar question over on stackoverflow here with a bounty, however, it seems as if perhaps I was too vague or just there is not enough people with knowledge in the subject.

• How do I draw a scrolling background?

  - by droidmachine

  How can I draw background tile in my 2D side-scrolling game? Is that loop logical for OpenGL es? My tile 2400x480. Also I want to use parallax scrolling for my game. batcher.beginBatch(Assets.background); for(int i=0; i<100; i++) batcher.drawSprite(0+2400*i, 240, 2400, 480, Assets.backgroundRegion); batcher.endBatch(); UPDATE And thats my onDrawFrame.I'm sending deltaTime for fps control. public void onDrawFrame(GL10 gl) { GLGameState state = null; synchronized(stateChanged) { state = this.state; } if(state == GLGameState.Running) { float deltaTime = (System.nanoTime()-startTime) / 1000000000.0f; startTime = System.nanoTime(); screen.update(deltaTime); screen.present(deltaTime); } if(state == GLGameState.Paused) { screen.pause(); synchronized(stateChanged) { this.state = GLGameState.Idle; stateChanged.notifyAll(); } } if(state == GLGameState.Finished) { screen.pause(); screen.dispose(); synchronized(stateChanged) { this.state = GLGameState.Idle; stateChanged.notifyAll(); } } }

• How to store bitmaps in memory?

  - by Geotarget

  I'm working with general purpose image rendering, and high-performance image processing, and so I need to know how to store bitmaps in-memory. (24bpp/32bpp, compressed/raw, etc) I'm not working with 3D graphics or DirectX / OpenGL rendering and so I don't need to use graphics card compatible bitmap formats. My questions: What is the "usual" or "normal" way to store bitmaps in memory? (in C++ engines/projects?) How to store bitmaps for high-performance algorithms, such that read/write times are the fastest? (fixed array? with/without padding? 24-bpp or 32-bpp?) How to store bitmaps for applications handling a lot of bitmap data, to minimize memory usage? (JPEG? or a faster [de]compression algorithm?) Some possible methods: Use a fixed packed 24-bpp or 32-bpp int[] array and simply access pixels using pointer access, all pixels are allocated in one continuous memory chunk (could be 1-10 MB) Use a form of "sparse" data storage so each line of the bitmap is allocated separately, reusing more memory and requiring smaller contiguous memory segments Store bitmaps in its compressed form (PNG, JPG, GIF, etc) and unpack only when its needed, reducing the amount of memory used. Delete the unpacked data if its not used for 10 secs.

• this.BoundingBox.Intersects(Wall[0].BoundingBox) not working properly

  - by Pieter

  I seem to be having this problem a lot, I'm still learning XNA / C# and well, trying to make a classic paddle and ball game. The problem I run into (and after debugging have no answer) is that everytime I run my game and press either of the movement keys, the Paddle won't move. Debugging shows that it never gets to the movement part, but I can't understand why not? Here's my code: // This is the If statement for checking Left movement. if (keyboardState.IsKeyDown(Keys.Left) || keyboardState.IsKeyDown(Keys.A)) { if (!CheckCollision(walls[0])) { Location.X -= Velocity; } } //This is the CheckCollision(Wall wall) boolean public bool CheckCollision(Wall wall) { if (this.BoundingBox.Intersects(wall.BoundingBox)) { return true; } return false; } As far as I can tell there should be absolutely no problem with this, I initialize the bounding box in the constructor whenever a new instance of Walls and Paddle is created. this.BoundingBox = new Rectangle(0, 0, Sprite.Width, Sprite.Height); Any idea as to why this isn't working? I have previously succeeded with using the whole Location.X < Wall.Location.X + Wall.Texture.Width code... But to me that seems like too much coding if a simple boolean check could be done.

• Using elapsed time for SlowMo in XNA

  - by Dave Voyles

  I'm trying to create a slow-mo effect in my pong game so that when a player is a button the paddles and ball will suddenly move at a far slower speed. I believe my understanding of the concepts of adjusting the timing in XNA are done, but I'm not sure of how to incorporate it into my design exactly. The updates for my bats (paddles) are done in my Bat.cs class: /// Controls the bat moving up the screen /// </summary> public void MoveUp() { SetPosition(Position + new Vector2(0, -moveSpeed)); } /// <summary> /// Controls the bat moving down the screen /// </summary> public void MoveDown() { SetPosition(Position + new Vector2(0, moveSpeed)); } /// <summary> /// Updates the position of the AI bat, in order to track the ball /// </summary> /// <param name="ball"></param> public virtual void UpdatePosition(Ball ball) { size.X = (int)Position.X; size.Y = (int)Position.Y; } While the rest of my game updates are done in my GameplayScreen.cs class (I'm using the XNA game state management sample) Class GameplayScreen { ........... bool slow; .......... public override void Update(GameTime gameTime, bool otherScreenHasFocus, bool coveredByOtherScreen) base.Update(gameTime, otherScreenHasFocus, false); if (IsActive) { // SlowMo Stuff Elapsed = (float)gameTime.ElapsedGameTime.TotalSeconds; if (Slowmo) Elapsed *= .8f; MoveTimer += Elapsed; double elapsedTime = gameTime.ElapsedGameTime.TotalMilliseconds; if (Keyboard.GetState().IsKeyDown(Keys.Up)) slow = true; else if (Keyboard.GetState().IsKeyDown(Keys.Down)) slow = false; if (slow == true) elapsedTime *= .1f; // Updating bat position leftBat.UpdatePosition(ball); rightBat.UpdatePosition(ball); // Updating the ball position ball.UpdatePosition(); and finally my fixed time step is declared in the constructor of my Game1.cs Class: /// <summary> /// The main game constructor. /// </summary> public Game1() { IsFixedTimeStep = slow = false; } So my question is: Where do I place the MoveTimer or elapsedTime, so that my bat will slow down accordingly?

• Previewing a Demo Level in Mobile for UDK?

  - by Reno Yeo

  I've already clicked on "Emulate Mobile Features" and everything has been compiled. I've also set the mobile previewer settings to iPhone 4's dimensions and features. However, when i click on the mobile previewer, a new window pops up but it goes into a "Not Responding" mode after a while. Is there anything I'm doing wrong? To be honest, I'm afraid of the difficulty curve required in learning UDK, but I am interested in developing a game for it.

• How to shade a texture two different colors?

  - by Venesectrix

  To give an example of what I'm asking about, I'll use Saints Row 3 since I've been playing that lately. In that game you can customize your looks and your car's appearance a lot. Your coat can have a primary color and a trim color. Your car can have a primary color and a stripe color, etc. Is there just a single coat texture that is being shaded two different colors somehow or are they overlaying a transparent second texture for the trim/stripes that gets shaded differently? If it's just one texture I'd like to know how it's done. If it's two different textures it seems like it's a waste of space. The second texture would be the same size as the first one but mostly transparent if you just wanted to lay it on top of the first one. Or are they just carefully positioning a second, smaller texture so that it aligns properly with the first one?

• Wheel Joint Implementation in AndEngine

  - by Siddharth

  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.

• Bridge made out of blocks at an angle

  - by Pozzuh

  I'm having a bit of trouble with the math behind my project. I want the player to be able to select 2 points (vectors). With these 2 points a floor should be created. When these points are parallel to the x-axis it's easy, just calculate the amount of blocks needed by a simple division, loop through that amount (in x and y) and keep increasing the coordinate by the size of that block. The trouble starts when the 2 vectors aren't parallel to an axis, for example at an angle of 45 degrees. How do I handle the math behind this? If I wasn't completely clear, I made this awesome drawing in paint to demonstrate what I want to achieve. The 2 red dots would be the player selected locations. (The blocks indeed aren't square.) http://i.imgur.com/pzhFMEs.png.

• How to implement Fog Of War with an shader?

  - by Cambrano

  Okay, I'm creating a RTS game and want to implement an AgeOfEmpires-like Fog Of War(FOW). That means a tile(or pixel) can be: 0% transparent (unexplored) 50% transparent black (explored but not in viewrange) 100% transparent(explored and in viewrange) RTS means I'll have many explorers (NPCs, buildings, ...). Okay, so I have an 2d array of bytes byte[,] explored. The byte value correlates the transparency. The question is, how do I pass this array to my shader? Well I think it is not possible to pass an entire array. So: what technique shall I use to let my shader know if a pixel/tile is visible or not?

• C++: Checking if an object faces a point (within a certain range)

  - by bojoradarial

  I have been working on a shooter game in C++, and am trying to add a feature whereby missiles shot must be within 90 degrees (PI/2 radians) of the direction the ship is facing. The missiles will be shot towards the mouse. My idea is that the ship's angle of rotation is compared with the angle between the ship and the mouse (std::atan2(mouseY - shipY, mouseX - shipX)), and if the difference is less than PI/4 (45 degrees) then the missile can be fired. However, I can't seem to get this to work. The ship's angle of rotation is increased and decreased with the A and D keys, so it is possible that it isn't between 0 and 2*PI, hence the use of fmod() below. Code: float userRotation = std::fmod(user->Angle(), 6.28318f); if (std::abs(userRotation - missileAngle) > 0.78f) return; Any help would be appreciated. Thanks!

• Coordinate and positioning problem on iOS with cocos2d-x

  - by Vexille

  I'm using cocos2d-x alongside with Marmalade and running some tests and tutorials before starting an actual project with them. So far things are working reasonably well on the windows simulator, Android and even on Blackberry's Playbook, but on iOS devices (iPhone and iPad) the positioning seems to be off. To make things clearer, I put together a scene that just draws an image in the middle of the screen. It worked as expected on everything else, but this is the result I got on an iPhone: To get the coordinates for the center of the screen I'm using the VisibleRect class from the TestCpp sample. It just uses sharedOpenGLView to get the visible size and visible origin, and calculate the center from that. CCSprite* test = CCSprite::create("Ball.png", CCRectMake(0, 0, 80, 80) ); test->setPosition( ccp(VisibleRect::center().x, VisibleRect::center().y) ); this->addChild(test); Also I have a noBorder policy set on AppDelegate: CCEGLView::sharedOpenGLView()->setDesignResolutionSize(designSize.width, designSize.height, kResolutionNoBorder); One funny thing is that I tried to deploy the TestCpp sample project to some iOS devices and it worked reasonably well on the iPhone, but on the iPad the application was only being drawn on a small portion of the screen - just like what happened on the iPhone when I tried using the ShowAll policy.

• How to display image in second layer in Cocos2d

  - by PeterK

  I am very new at Cocos2d and is testing to displaying an image over the "Hello World" text on a second layer and need help to get it work. I guess it is some basic stuff here and appreciate any tips etc. with this. I know that if i put the display-code (myLayer1) in the "init" it work or do the call [self goHere] from the "init" in myLayer1 it works but i want to call the "goHere" directly. I have the following code: HelloWorld.m: #import "HelloWorldLayer.h" #import "myLayer1.h" // HelloWorldLayer implementation @implementation HelloWorldLayer +(CCScene *) scene { // 'scene' is an autorelease object. CCScene *scene = [CCScene node]; // 'layer' is an autorelease object. HelloWorldLayer *layer = [HelloWorldLayer node]; myLayer1 *layer1 = [myLayer1 node]; // add layer as a child to scene [scene addChild: layer]; [scene addChild: layer1]; // return the scene return scene; } // on "init" you need to initialize your instance -(id) init { // always call "super" init // Apple recommends to re-assign "self" with the "super" return value if( (self=[super init])) { // create and initialize a Label CCLabelTTF *label = [CCLabelTTF labelWithString:@"Hello World" fontName:@"Marker Felt" fontSize:64]; // ask director the the window size CGSize size = [[CCDirector sharedDirector] winSize]; // position the label on the center of the screen label.position = ccp( size.width /2 , size.height/2 ); // add the label as a child to this Layer [self addChild: label]; myLayer1 *a1 = [myLayer1 new]; [a1 goHere]; [myLayer1 release]; } return self; } myLayer1.m: #import "myLayer1.h" @implementation myLayer1 -(void)goHere { NSLog(@">>>>goHere<<<<"); CGSize size = [[CCDirector sharedDirector] winSize]; CCSprite *vv = [CCSprite spriteWithFile:@"hand.png"]; vv.position = ccp( size.width /2 , size.height/2 ); [self addChild:vv z:3]; } -(id) init { // always call "super" init // Apple recommends to re-assign "self" with the "super" return value if( (self=[super init])) { } return self; } @end

• Improving the efficiency of my bloom/glow shader

  - by user1157885

  I'm making a neon style game where everything is glowing but the glow I have is kinda small and I want to know if there's an efficient way to increase the size of it other than increasing the pixel sample iterations. Right now I have something like this: float4 glowColor = tex2D(glowSampler, uvPixel); //Makes the inital lines brighter/closer to white if (glowColor.r != 0 || glowColor.g != 0 || glowColor.b != 0) { glowColor += 0.5; } //Loops over the weights and offsets and samples from the pixels based on those numbers for (int i = 0; i < 20; i++) { glowColor += tex2D(glowSampler, uvPixel + glowOffsets[i] + 0.0018) * glowWeights[i]; } finalColor += glowColor; for the offsets it moves up, down, left and right (5 times each so it loops over 20 times) and the weights just lower the glow amount the further away it gets. The method I was using before to increase it was to increase the number of iterations from 20 to 40 and to increase the size of the offset/weight array but my computer started to have FPS drops when I was doing this so I was wondering how can I make the glow bigger/more vibrant without making it so CPU/Gcard intensive?

• Creating a 2D Line Branch (Part 2)

  - by Danran

  Yesterday i asked this question on how to create a 2D line branch; Creating a 2D Line Branch And thanks to the answered provided, i now have this nice looking main branch; *coloured to show the different segments in the final item. Now is the time now to branch things off as discussed in the article; http://drilian.com/2009/02/25/lightning-bolts/ Again however i am confused as to the meaning of the following pseudo code; splitEnd = Rotate(direction, randomSmallAngle)*lengthScale + midPoint; I'm unsure how to actually rotate this correctly. In all honesty i'm abit unsure what to-do completely at this part, "splitEnd" will be a Vector3, so whatever happens in the rotate function must then return some form of directional rotation which is then * by a scale to create length and then added to the midPoint. I'm not sure. If someone could explain what i'm meant to be doing in this part that would be really grateful.

• Tic-Tac-Toe game AI

  I'm looking into creating a simple tic tac toe/noughts and crosses game in Actionscript3 and am trying to understand the ideas behind the AI used in a game like this. I've seen some simplistic examples online but from what I've read a game tree or something like minimax is the best way to go about this. Can anyone help explain or reference any good examples of this? I've seen that there is a library called as3ds - data structures for game developers which has a number of classes that might help tie this together? Any info/examples or help is much appreciated.

• Draw Cards and Eliminate Cards Problem

  - by Jen

  I am having a problem in this question. I want a system inside a game wherein the player draws 2 cards randomly, and the enemy draws 2 cards randomly. Then, what the program does is to print out to the console the cards the player draw and the enemy's. The cards should not conflict and must not be the same. Then lastly, the program prints out the card that was not drawn by both the player and the enemy. Here's how I did it but it was lengthy and full of errors: import java.util.Random; public class Draw { public static Random random = new Random(); public static String cards[] = {"Hall", "Kitchen", "Billiard", "Study", "Pool"}; public static int playercounter; public static int enemycounter; public static String playercardA = null; public static String playercardB = null; public static String enemycardA = null; public static String enemycardB = null; public String lastcard = null; public static void playercardAdraw() { playercounter = random.nextInt(5); playercardA = cards[playercounter]; } public static void playercardBdraw() { playercounter=random.nextInt(5); playercardB= cards[playercounter]; if (playercardB==playercardA || playercardB == enemycardA || playercardB == enemycardB) { return; } } public static void enemycardAdraw () { enemycounter = random.nextInt(5); enemycardA=cards[enemycounter]; if (enemycardA == playercardA || enemycardA == playercardB) { return; } } public static void enemycardBdraw () { enemycounter = random.nextInt(5); enemycardB=cards[enemycounter]; if (enemycardB == playercardA || enemycardB == playercardB || enemycardB == enemycardA) { return; } } public static void main (String args []) { System.out.println("Starting to draw..."); System.out.println("Player's Turn: "); playercardAdraw(); System.out.println("Player's first card: " + playercardA); playercardBdraw(); System.out.println("Player's second card: " + playercardB); System.out.println("Enemy's Turn: "); enemycardAdraw(); System.out.println("Enemy's first card: " + enemycardA); enemycardBdraw(); System.out.println("Enemy's Second card: " + enemycardB); } }

• Cocos2D: Upgrading from OpenGL ES 1.1 to 2.0

  - by Alex

  I have recently starting upgrading my ios game to the latest Cocos2D (2.0 rc), and I am having some difficulties upgrading my texture generation code to OpenGL 2.0. In the old version I generated images with this code: CCRenderTexture *rt = [CCRenderTexture renderTextureWithWidth:WIDTH height:HEIGHT]; [rt beginWithClear:bgColor.r g:bgColor.g b:bgColor.b a:bgColor.a]; glDisable(GL_TEXTURE_2D); glDisableClientState(GL_TEXTURE_COORD_ARRAY); glVertexPointer(2, GL_FLOAT, 0, verts); glColorPointer(4, GL_FLOAT, 0, colors); glDrawArrays(GL_TRIANGLE_STRIP, 0, (GLsizei)nVerts); glEnableClientState(GL_TEXTURE_COORD_ARRAY); glEnable(GL_TEXTURE_2D); [rt end]; But since OpenGL 2.0 works differently this code won't work. What is the best way to use the new OpenGL?

• Find Nearest Object

  - by ultifinitus

  I have a fairly sizable game engine created, and I'm adding some needed features, such as this, how do I find the nearest object from a list of points? In this case, I could simply use the Pythagorean theorem to find the distance, and check the results. I know I can't simply add x and y, because that's the distance to the object, if you only took right angle turns. However I'm wondering if there's something else I could do? I also have a collision system, where essentially I turn objects into smaller objects on a smaller grid, kind of like a minimap, and only if objects exist in the same gridspace do I check for collisions, I could do the same thing, only make the gridspace larger to check for closeness. (rather than checking every. single. object) however that would take additional setup in my base class and clutter up the already cluttered object. TL;DR Question: Is there something efficient and accurate that I can use to detect which object is closest, based on a list of points and sizes?

• Multiplayer tile based movement synchronization

  - by Mars

  I have to synchronize the movement of multiple players over the Internet, and I'm trying to figure out the safest way to do that. The game is tile based, you can only move in 4 directions, and every move moves the sprite 32px (over time of course). Now, if I would simply send this move action to the server, which would broadcast it to all players, while the walk key is kept being pressed down, to keep walking, I have to take this next command, send it to the server, and to all clients, in time, or the movement won't be smooth anymore. I saw this in other games, and it can get ugly pretty quick, even without lag. So I'm wondering if this is even a viable option. This seems like a very good method for single player though, since it's easy, straight forward (, just take the next movement action in time and add it to a list), and you can easily add mouse movement (clicking on some tile), to add a path to a queue, that's walked along. The other thing that came to my mind was sending the information that someone started moving in some direction, and again once he stopped or changed the direction, together with the position, so that the sprite will appear at the correct position, or rather so that the position can be fixed if it's wrong. This should (hopefully) only make problems if someone really is lagging, in which case it's to be expected. For this to work out I'd need some kind of queue though, where incoming direction changes and stuff are saved, so the sprite knows where to go, after the current movement to the next tile is finished. This could actually work, but kinda sounds overcomplicated. Although it might be the only way to do this, without risk of stuttering. If a stop or direction change is received on the client side it's saved in a queue and the char keeps moving to the specified coordinates, before stopping or changing direction. If the new command comes in too late there'll be stuttering as well of course... I'm having a hard time deciding for a method, and I couldn't really find any examples for this yet. My main problem is keeping the tile movement smooth, which is why other topics regarding synchronization of pixel based movement aren't helping too much. What is the "standard" way to do this?

• Whole map design vs. tiles array design

  - by Mikalichov

  I am working on a 2D RPG, which will feature the usual dungeon/town maps (pre-generated). I am using tiles, that I will then combine to make the maps. My original plan was to assemble the tiles using Photoshop, or some other graphic program, in order to have one bigger picture that I could then use as a map. However, I have read on several places people talking about how they used arrays to build their map in the engine (so you give an array of x tiles to your engine, and it assemble them as a map). I can understand how it's done, but it seems a lot more complicated to implement, and I can't see obvious avantages. What is the most common method, and what are advantages/disadvantages of each?
