• Cocos2dx- Draw primitives(polygons) on Update

  - by Haider

  In my game I'm trying to draw polygons on on each step i.e. update method. I call draw() method to draw new polygon with dynamic vertices. Following is my code: void HelloWorld::draw(){glLineWidth(1);CCPoint filledVertices[] = {ccp(drawX1,drawY1),ccp(drawX2,drawY2), ccp(drawX3,drawY3), ccp(drawX4,drawY4)};ccDrawSolidPoly( filledVertices, 4, ccc4f(0.5f, 0.5f, 1, 1 ));} I call the draw() method from the update(float dt) method. The engine is behaving inconsistently i.e. sometimes it displays the polygons and on other occasions it does not. Is it the right approach to do such a task? If not what is the best way to display large number of primitives?

• ScreenManagement better practices ?! Textbox not focusing

  - by xykudyax

  I saw a question here using DataTemplates with WPF for ScreenManagement, I was curious and I gave it a try I think the ideia is amazing and very clean. Though I'm new to WPF and I read a lot of times that almost everything should be made in XAML and very little should be "coded behind". My questions resolves about using the datatemplate ideia, WHERE should the code that calls the transitions be? where should I define which commands are avaiable in which screens. For example: [ScreenA] Commands: Pressing B - Goes to state B Pressing ESC - Exits [ScreenB] Commands: Pressing A - Goes to state A Pressing SPACE - Exits where do I define the keyEventHandlers? and where do I call the next screen? I'm doing this as an hobby for learning and "if you are learning, better learn it right" :) Thank you for your time. Yes the Q/A I was talking is: What's a good way to handle game screen management in WPF? What I've done so far was to create a Screen class (derived from UserControl) and create some virtual methods: - one for Initializing stuff (like focus a given component by default) - another for inputHandling I handle it by using a switch case and by listening to the PreviewKeyDown event from the parent container (MainWindow) Im not able to do it another way! Help?!. - and a finally one that removes the keyEvent method (when the screen is terminated) Parent.PreviewKeyDown -= OnKeyDown; am I doing okay? I face a problem. When I add a new screen (userControl) containing a TextBox I'm not able to give it autofocus :/ The Caret is there but is not blinking and I have to hit "TAB" before being able to input anything at all :/

• Unity: Spin wheels to move vehicle

  - by Paul Manta

  I am just getting started with Unity and I'd like to ask a question. If I have a "Vehicle" object that has two children: "FrontWheel" and "BackWheel" (both 'wheels' are cylinders), how should I set everything up such that I can move the entire vehicle by turning its wheels? When I apply a torque to "FrontWheel", the vehicle starts to move, but instead of the whole thing the moving together, the chassis is rolling on the cylinders and eventually falls off. How can I prevent it from doing that?

• Why doesn't Unity's OnCollisionEnter give me surface normals, and what's the most reliable way to get them?

  - by michael.bartnett

  Unity's on collision event gives you a Collision object that gives you some information about the collision that happened (including a list of ContactPoints with hit normals). But what you don't get is surface normals for the collider that you hit. Here's a screenshot to illustrate. The red line is from ContactPoint.normal and the blue line is from RaycastHit.normal. Is this an instance of Unity hiding information to provide a simplified API? Or do standard 3D realtime collision detection techniques just not collect this information? And for the second part of the question, what's a surefire and relatively efficient way to get a surface normal for a collision? I know that raycasting gives you surface normals, but it seems I need to do several raycasts to accomplish this for all scenarios (maybe a contact point/normal combination misses the collider on the first cast, or maybe you need to do some average of all the contact points' normals to get the best result). My current method: Back up the Collision.contacts[0].point along its hit normal Raycast down the negated hit normal for float.MaxValue, on Collision.collider If that fails, repeat steps 1 and 2 with the non-negated normal If that fails, try steps 1 to 3 with Collision.contacts[1] Repeat 4 until successful or until all contact points exhausted. Give up, return Vector3.zero. This seems to catch everything, but all those raycasts make me queasy, and I'm not sure how to test that this works for enough cases. Is there a better way?

• Traffic estimation for a multiplayer flash game

  - by Steve Addington

  hey, i want to know if my rough traffic estimations are right, it would be for a pretty simple realtime flashgame in the style of haxball (but not as a soccer game) heres a video of it http://www.youtube.com/watch?v=z_xBdFg1RcI So here comes my estimation, i dont know if they are realistic! i hope someone can help me. consider the packet attached as a typical one sent every 200ms, its 148bytes + 64 bytes of header will make around a 200bytes packet. The server will receive 200bytes x 6 players x 5 times a sec=6000bytes/s=5.85Kbytes/s=46.9kbit/s plus he has to send all back to the players, so at this point are 94Kbit/s.The server received all the information, perform the definitive calculation and send the new position to all players, in a bigger packet of around 900bytes that have to be delivered to the others 6, which makes 900bytes x 6 players x 5 times a sec=27000bytes/s=26Kbytes/s=210kbit/s. overall that would be 26kbyte per second. thats like 130mb traffic per hour for a 6player room. but somehow i think the numbers are too high? that would be really much traffic for such a simple game. did i calculate something wrong?

• Level editor event system, how to translate event to game action

  - by Martino Wullems

  Hello, I've been busy trying to create a level editor for a tile based game i'm working on. It's all going pretty fine, the only thing i'm having trouble with is creating a simple event system. Let's say the player steps on a particulair tile that had the action "teleport" assigned to it in the editor. The teleport string is saved in the tile object as a variable. When creating the tilegrid an actionmanager class scans the action variable and assigns actions to the variable. public static class ActionManager { public static function ParseTileAction(tile:Tile) { switch(tile.action) { case "TELEPORT": //assign action here break; } } } Now this is an collision event, so I guess I should also provide an object to colide with the tile. But what if it would have to count for collision with all objects in the world? Also, checking for collisions in the actionmanager class doesn't seem very efficient. Am I even on the right track here? I'm new to game design so I could be completly off track. Any tips on how handeling and creating events using an editor is usually done would be great. The main problem i'm having is the Thanks in advance.

• Game server for an android/iOS turn-based board-game

  - by Cyril

  I am currently programming an iPhone game and I would like to create an online multiplayer mode. In the future, this app will be port to Android devices, so I was wondering how to create the game-server? First at all, which language should I choose? How to make a server able to communicate both with programs written in objective-c and Java? Then, how to effectively do it? Is it good if I open a socket by client (there'll be 2)? What kind of information should I send to the server? to the clients?

• My raycaster is putting out strange results, how do I fix it?

  - by JamesK89

  I'm working on a raycaster in ActionScript 3.0 for the fun of it, and as a learning experience. I've got it up and running and its displaying me output as expected however I'm getting this strange bug where rays go through corners of blocks and the edges of blocks appear through walls. Maybe somebody with more experience can point out what I'm doing wrong or maybe a fresh pair of eyes can spot a tiny bug I haven't noticed. Thank you so much for your help!

• Unity3d: Box collider attached to animated FBX models through scripts at run-time have wrong dimension

  - by Heisenbug

  I have several scripts attached to static and non static models of my scene. All models are instantiated at run-time (and must be instantiated at run-time because I'm procedural building the scene). I'd like to add a BoxCollider or SphereCollider to my FBX models at runtime. With non animated models it works simply requiring BoxCollider component from the script attached to my GameObject. BoxCollider is created of the right dimension. Something like: [RequireComponent(typeof(BoxCollider))] public class AScript: MonoBehavior { } If I do the same thing with animated models, BoxCollider are created of the wrong dimension. For example if attach the script above to penelopeFBX model of the standard asset, BoxCollider is created smaller than the mesh itself. How can I solve this?

• How to load stacking chunks on the fly?

  - by Brettetete

  I'm currently working on an infinite world, mostly inspired by minecraft. A Chunk consists of 16x16x16 blocks. A block(cube) is 1x1x1. This runs very smoothly with a ViewRange of 12 Chunks (12x16) on my computer. Fine. When I change the Chunk height to 256 this becomes - obviously - incredible laggy. So what I basically want to do is stacking chunks. That means my world could be [8,16,8] Chunks large. The question is now how to generate chunks on the fly? At the moment I generate not existing chunks circular around my position (near to far). Since I don't stack chunks yet, this is not very complex. As important side note here: I also want to have biomes, with different min/max height. So in Biome Flatlands the highest layer with blocks would be 8 (8x16) - in Biome Mountains the highest layer with blocks would be 14 (14x16). Just as example. What I could do would be loading 1 Chunk above and below me for example. But here the problem would be, that transitions between different bioms could be larger than one chunk on y. My current chunk loading in action For the completeness here my current chunk loading "algorithm" private IEnumerator UpdateChunks(){ for (int i = 1; i < VIEW_RANGE; i += ChunkWidth) { float vr = i; for (float x = transform.position.x - vr; x < transform.position.x + vr; x += ChunkWidth) { for (float z = transform.position.z - vr; z < transform.position.z + vr; z += ChunkWidth) { _pos.Set(x, 0, z); // no y, yet _pos.x = Mathf.Floor(_pos.x/ChunkWidth)*ChunkWidth; _pos.z = Mathf.Floor(_pos.z/ChunkWidth)*ChunkWidth; Chunk chunk = Chunk.FindChunk(_pos); // If Chunk is already created, continue if (chunk != null) continue; // Create a new Chunk.. chunk = (Chunk) Instantiate(ChunkFab, _pos, Quaternion.identity); } } // Skip to next frame yield return 0; } }

• Logic behind a bejeweled-like game

  - by Joe

  In a prototype I am doing, there is a minigame similar to bejeweled. Using a grid that is a 2d array (int[,]) how can I go about know when the user formed a match? I only care about horizontally and vertically. Off the top of my head I was thinking I would just look each direction. Something like: int item = grid[x,y]; if(grid[x-1,y]==item) { int step=x; int matches =2; while(grid[step-1,y]==item) { step++; matches++ } if(matches>2) //remove all matching items } else if(grid[x+1,y]==item //.... else if(grid[x,y-1==item) //... else if(grid[x,y+1]==item) //... It seems like there should be a better way. Is there?

• Best way to distribute graphics, audio and levels with an SDL game?

  - by Kristopher

  I'm working on finishing up a game written in C++ with SDL I've been working on for awhile, and I'm starting to ponder how I'm going to distribute it. It has hundreds of images that are loaded and used throughout the game, as well as a couple dozen .wav files for audio effects. What is the best way to distribute these? Should I just include the folders with all the files? Or is there a way I can package them into a single file, then open and extract them in my application? What's the best way to go about this?

• How to create a "retro" pixel shader for transformed 2D sprites that maintains pixel fidelity?

  - by David Gouveia

  The image below shows two sprites rendered with point sampling on top of a background: The left skull has no rotation/scaling applied to it, so every pixel matches perfectly with the background. The right skull is rotated/scaled, and this results in larger pixels that are no longer axis aligned. How could I develop a pixel shader that would render the transformed sprite on the right with axis aligned pixels of the same size as the rest of the scene? This might be related to how sprite scaling was implemented in old games such as Monkey Island, because that's the effect I'm trying to achieve, but with rotation added. Edit As per kaoD's suggestions, I tried to address the problem as a post-process. The easiest approach was to render to a separate render target first (downsampled to match the desired pixel size) and then upscale it when rendering a second time. It did address my requirements above. First I tried doing it Linear -> Point and the result was this: There's no distortion but the result looks blurred and it loses most of the highlights colors. In my opinion it breaks the retro look I needed. The second time I tried Point -> Point and the result was this: Despite the distortion, I think that might be good enough for my needs, although it does look better as a still image than in motion. To demonstrate, here's a video of the effect, although YouTube filtered the pixels out of it: http://youtu.be/hqokk58KFmI However, I'll leave the question open for a few more days in case someone comes up with a better sampling solution that maintains the crisp look while decreasing the amount of distortion when moving.

• Is it better to hard code data or find an algorithm?

  - by OghmaOsiris

  I've been working on a boardgame that has a hex grid as the board (the upper right grid in the image below) Since the board will never change and the spaces on the board will always be linked to the same other spaces around it, should I just hard code every space with the values that I need? Or should I use various algorithms to calculate links and traversals? To be more specific, my board game is a 4 player game where each player has a 5x5x5x5x5x5 hex grid (again, the upper right grid in th eimage above). The object is to get from the bottom of the grid to the top, with various obstacles in the way, and each players being able to attack eachother from the edge of their grid onto other players based on a range multiplier. Since the players grid will never change and the distance of any arbitrary space from the edge of the grid will always be the same, should I just hard code this number into each of the spaces, or should I still use a breadth first search algorithm when players are attacking? The only con I can think of for hard coding everything is that I'm going to code 9+ 2(5+6+7+8) = 61 individual cells. Is there anything else that I'm missing that I should consider using more complex algorithms?

• How to implement a stack of game states in C++

  - by Lisandro Vaccaro

  I'm new to C++ and as a college proyect I'm building a 2D platformer with some classmates, I recently read that it's a good idea to have a stack of gamestates instead of a single global variable with the game state (which is what I have now) but I'm not sure how to do it. Currently this is my implementation: class GameState { public: virtual ~GameState(){}; virtual void handle_events() = 0; virtual void logic() = 0; virtual void render() = 0; }; class Menu : public GameState { public: Menu(); ~Menu(); void handle_events(); void logic(); void render(); }; Then I have a global variable of type GameState: GameState *currentState = NULL; And in my Main I define the currentState and call it's methods: int main(){ currentState = new Menu(); currentState.handle_events(); } How can I implement a stack or something similar to go from that to something like this: int main(){ statesStack.push(new Menu()); statesStack.getTop().handle_events(); }

• How do I scroll to follow my sprite in the physical world?

  - by Esteban Quintero

  I am using andengine to make a game where a sprite (player) is going up across the stage, and I want the camera to stay centred on the sprite the entire time. This is my world so far: final Rectangle ground = new Rectangle(0, CAMERA_HEIGHT - 2, CAMERA_WIDTH, 2, vertexBufferObjectManager); final Rectangle roof = new Rectangle(0, 0, CAMERA_WIDTH, 2, vertexBufferObjectManager); final Rectangle left = new Rectangle(0, 0, 2, CAMERA_HEIGHT, vertexBufferObjectManager); final Rectangle right = new Rectangle(CAMERA_WIDTH - 2, 0, 2, CAMERA_HEIGHT, vertexBufferObjectManager); final FixtureDef wallFixtureDef = PhysicsFactory.createFixtureDef(0, 0.5f, 0.5f); PhysicsFactory.createBoxBody(this.mPhysicsWorld, ground, BodyType.StaticBody, wallFixtureDef); PhysicsFactory.createBoxBody(this.mPhysicsWorld, roof, BodyType.StaticBody, wallFixtureDef); PhysicsFactory.createBoxBody(this.mPhysicsWorld, left, BodyType.StaticBody, wallFixtureDef); PhysicsFactory.createBoxBody(this.mPhysicsWorld, right, BodyType.StaticBody, wallFixtureDef); /* Create two sprits and add it to the scene. */ this.mScene.setBackground(autoParallaxBackground); this.mScene.attachChild(ground); this.mScene.attachChild(roof); this.mScene.attachChild(left); this.mScene.attachChild(right); this.mScene.registerUpdateHandler(this.mPhysicsWorld); The problem is that when the sprite reaches the top wall, it crashes. How can I fix this?

• Drawing a textured triangle with CPU instead of GPU

  - by Jenko

  I understand the benefits of GPU rendering and such, but for a certain limited application I need to render textured triangles purely using CPU. I've built a 3D engine capable of object handling, transform, projection, culling and the likes ... now all I need is a little code snippet that draws a single textured triangle onto a bitmap... any language accepted! Inputs: Texture bitmap, Triangle U/V/W coords, Triangle X/Y screen coords Output: The textured triangle drawn at the given screen coords I've currently been using a platform function to draw triangles to screen, but I'm looking to handle it myself to speeden up the process.

• Camera changes view when controller connected

  - by ChocoMan

  I have a weird situation. I have a model set to 0 for X,Y and Z. My camera's position is set to: 0 (X-value, but updates when the model moves around) the model's height + 20f (about the same level as the model's shoulders) 25f (behind the model) Without the controller plugged in, everything looks fine as I want it. But as soon as I plug the controller in, the camera aims to the sky! But when I unplug the controller, the camera is back to what it should be. Does anyone have any insight as to what may cause this from plugging a controller in?

• Kepler orbit : get position on the orbit over time

  - by Artefact2

  I'm developing a space-simulation related game, and I am having some trouble implementing the movement of binary stars, like this: The two stars orbit their centroid, and their trajectories are ellipses. I basically know how to determine the angular velocity at any position, but not the angular velocity over time. So, for a given angle, I can very easily compute the stars position (cf. http://en.wikipedia.org/wiki/Orbit_equation). I'd want to get the stars position over time. The parametric equations of the ellipse works but doesn't give the correct speed : { X(t) = a×cos(t) ; Y(t) = b×sin(t) }. Is it possible, and how can it be done?

• How to integrate game logic in game engines

  - by MahanGM

  Recently I'm working on a 2d game engine example in .Net with C#. My main problem is that I can't figure out how I should include the game logic within the game. Currently I have a base engine which is a set of classes that they are running sub-systems like Render, Sound, Input and Core functionality. There is an editor which helps the user to add resources, build levels, write scripts and other stuffs. I came up with an idea to use Reflection and CSharpCodeProvider from my editor to compile the written code. This way I can get an executable of my product too. This way is quite well but I would like to know what's really the solution and architecture to do this. My engine's role is 2d platform. The scripting language is C# right now because I can't consist any other embeddable language for now. The game needs compilation and CSharpCodeProvider is the only way for me to do it meantime.

• Separate shaders from HTML file in WebGL

  - by Chris Smith

  I'm ramping up on WebGL and was wondering what is the best way to specify my vertex and fragment shaders. Looking at some tutorials, the shaders are embedded directly in the HTML. (And referenced via an ID.) For example: <script id="shader_1-fs" type="x-shader/x-fragment"> precision highp float; void main(void) { // ... } </script> <script id="shader_1-vs" type="x-shader/x-vertex"> attribute vec3 aVertexPosition; uniform mat4 uMVMatrix; // ... My question is, is it possible to have my shaders referenced in a separate file? (Ideally as plain text.) I presume this is straight forward in JavaScript. Is there essentially a way to do this: var shaderText = LoadRemoteFileOnSever('/shaders/shader_1.txt');

• Reuseable Platform For Custom Board Game

  - by George Bailey

  Is there a generic platform to allow me to customize the rules to a board game. The board game uses a square grid, similar to Checkers or Chess. I was hoping to take some of the work out of creating this computer opponent, by reusing what is already written. I would think that there would be a pre-written routine for deciding which moves would lead to the best outcome, and all that I would need to program is the pieces, legal moves, what layout constitutes a win/lose or draw, and perhaps some kind of scoring for value of pieces. I have seen chess programs that appear to use a recursive routine, so they think anywhere from 2 to 20 moves ahead to create varying degrees of difficulty. I have noticed this on chess.com. The game I am programming will not be as complex. Is there a platform designed to be re-used for different grid/piece based games. JavaScript would be preferable, but Java or Perl would be acceptable.

• Wait till all CCActions have completed

  - by tGilani

  I am developing a simple cocos2d game in which I want to animate two CCSprites simultaneously, and for this purpose I simply set CCActions on respective `CCSprite's as follows. [first runAction:[CCMoveTo actionWithDuration:1 position:secondPosition]]; [second runAction:[CCMoveTo actionWithDuration:1 position:firstPosition]]; Now I want to wait till the animations are complete, so I can perform the next step. How should I wait for these animations to finish? There are actually two method calls, the first one animates the objects via the code above and second call does the other animation. I need to delay the second method call until the animations in first are complete. (I would not like to use CCCallFunc blocks as I want to call the second method from the same caller as the first one.
