• DirectX 10 Instancing Problem (objects cannot be seen)

  - by Riffraff

  Right now I'm trying to implement an area that is filled with vegetation. I have tried mesh version and right now I'm trying to implement instancing version but I cannot manage to make it work. I can't see any object. I search for any problem of buffers with FAILED() and D3D10_CREATE_DEVICE_DEBUG but they didn't help me either. Right now I don't even know which part of my code to share to explain my problem.

• Implementing my Entity System. Questions about some problems I have found.

  - by Notbad

  Hi!, Well during this week I have deciding about implementation of my entity system. It is a big topic so it has been difficult to take one option from the whole. This has been my decision: 1) I don't have an entity class it is just an id. 2) I have systems that contain a list of components (the list is homegenous, I mean, RenderSystem will just have RenderComponents). 3) Compones will be just data. 4) There would be some kind of "entity prototypes" in a manager or something from we will create entity instances.Ideally they will define the type of components it has and initialization data. 5) Prototype code to create an entity (this is from the top of my head): int id=World::getInstance()->createEntity("entity template"); 6) This will notify all systems that a new entity has been created, and if the entity needs a component that the system handles it will add it to the entity. Ok, this are the ideas. Let's see if some can help with the problems: 1) The main problem is this templates that are sent to the systems in creation process to populate the entity with needed components. What would you use, an OR(ed) int?, a list of strings?. 2) How to do initialization for components when the entity has been created? How to store this in the template? I have thought about having a function in the template that is virtual and after entity is created an populated, gets the components and sets initialization values. 3) Don't you think this is a lot of work for just an entity creation?. Sorry for the long post, I have tried to expose my ideas and finding in order other could have a start beside exposing my problems. Thanks in advance, Notbad.

• Particle Effect Completion

  - by Siddharth

  In my game I use particle effect for various purposes. In that I detect the completion of the particle effect. Basically I want to do something after completion of the particle effect. But the problem is that I didn't able to find the particle effect completion. So any community member please help me. EDIT : I was creating particle effect using following code pointParticleEmtitter = new PointParticleEmitter(pX, pY); particleSystem = new ParticleSystem(pointParticleEmtitter, maxRate, minRate, maxParticles, mParticleTextureRegion.deepCopy()); particleSystem.setBlendFunction(GL10.GL_SRC_ALPHA, GL10.GL_ONE); particleSystem.addParticleInitializer(new ColorInitializer(0f, 0f, 1f)); particleSystem.addParticleModifier(new AlphaModifier(1, 0, 0, 0.5f)); particleSystem.addParticleModifier(new ExpireModifier(0.5f)); gameObject.getScene().attachChild(particleSystem); Using above code the particle effect was started but when finished that I want to detect. After finishing effect I want to remove the object from the scene.

• Ideas for card deck names [closed]

  - by Milan Babuškov

  I'm creating a card game, and wish to offer players to choose from different sets of playing cards. The game logic remains the same, only the design and graphics on the cards would be different. It would feature classic French set, German/Hungarian one, and a bunch of other custom designed ones. I'm looking for some cool names to give to those sets. I thought maybe to use names of some world cities like "London set", "Paris set", "Tokyo set", but there might be something better. I know this is really open-ended question, so there might not be a definitive "correct" answer, but I hope this kind of brainstorming would be useful to anyone looking for ideas to name a set of... well, anything. I'll up-vote any good idea, no matter if I don't end up using any of those.

• Most supported/easiest to get started gamedev language?

  - by user1009013

  In what language are the most libraries/frameworks (like lwjgl for Java, XNA for C#)? What language is the easiest to start making a game (very easy to get a 3D-environment rendered)? What language has the friendliest learning curve? Say I want to make a game and I don't know any programming languages, I want to develop for any platform(so don't give the answer "the one you know best/the platform you are working on"), then what is the best language to start with. I get this question a lot "I have this and that ideas for a game and want to make it, what language should I use"(mostly asked by beginning programmers), but I don't know how to answer that. The answer "use the one you are most familiar with", because sometimes they don't even know a language yet... I am not asking for someone's personal opinion, but an objective list of what languages are the easiest/most supported/have the most/best libraries/frameworks to get started with gamedevelopment.

• Drawing visible tiles - side scrolling

  - by Troubleshoot

  Currently I'm calling drawMap every time repaint is called. This is the code I've written for my drawMap method so far. public void drawMap(Graphics2D g2d) { float cameraX = Player.getX() - (Frame.CANVAS_WIDTH / 2); float cameraY = Player.getY() - (Frame.CANVAS_HEIGHT / 2); int tileX = (int) cameraX; int tileY = (int) cameraY; int xIndent = 0, yIndent = 0; int a = 0, b = 0; while (tileX % TILE_SIZE != 0) { tileX--; xIndent++; } while (tileY % TILE_SIZE != 0) { tileY--; yIndent++; } for (int y = tileY; y < tileY + Frame.CANVAS_HEIGHT; y += Map.TILE_SIZE) { for (int x = tileX; x < tileX + Frame.CANVAS_WIDTH; x += Map.TILE_SIZE) { if ((y / TILE_SIZE < 0 || x / TILE_SIZE < 0) || (y / TILE_SIZE > columnSize)) break; g2d.drawImage(map[y / TILE_SIZE][x / TILE_SIZE], a - xIndent, b - yIndent, null); a += TILE_SIZE; } a = 0; b += TILE_SIZE; } } The idea behind this is that it gets the camera position and draws the map relative to the player position. However, instead of the player being in the center of the screen all the time, the player actually moves away from the center as it scrolls to the right, and moves towards to center as it scrolls to the left. I've been trying to pinpoint what I've done wrong but I can't seem to find it. My code also seems quite messy, so am I doing this the correct way?

• Box2D `ApplyLinearImpulse` is not working whereas `SetLinearVelocity` works

  - by Narek

  I need to mimic jumping behavior for the player in my game. Player consists of two fixtures with circle and rectangle shapes. Rectangle I use to detect ground and it is a sensor. Is some point for jumping I do this: float impulseY = body->GetMass() * PLAYER_JUMPING_VEOCITY / PTM_RATIO * std::sin(PLAYER_JUMPING_ANGLE * PI / 180); body->ApplyLinearImpulse(b2Vec2(0, impulseY), body->GetWorldCenter(), true); and player does not jump. But when I do this: body->SetLinearVelocity(b2Vec2(0, PLAYER_JUMPING_VEOCITY / PTM_RATIO * std::sin(PLAYER_JUMPING_ANGLE * PI / 180))); my player jumps. Also when I change the rectangle shape to be normal (not sensor) shape, its works again. Why? Just in case here are the parameters of my rectangular sensor: b2PolygonShape boxShape; boxShape.SetAsBox(width * 0.5/2/PTM_RATIO, height * 0.2/2/PTM_RATIO, b2Vec2(0, -height * 0.4 /PTM_RATIO), 0); b2FixtureDef boxFixtureDef; boxFixtureDef.friction = 0; boxFixtureDef.restitution = 0; boxFixtureDef.density = 1; boxFixtureDef.isSensor = true; boxFixtureDef.userData = static_cast<void*>(PLAYER_GROUP);

• OpenGL render to texture causing edge artifacts

  - by mysticalOso

  This is my first post here so any help would be massively appreciated :) I'm using C++ with SDL and OpenGL 3.3 When rendering directly to screen I get the following result And when I render to texture I this happens Anti-aliasing is turned off for both. I'm guessing this has something to do with depth buffer accuracy but I've tried a lot of different methods to improve the result but, no success :( I'm currently using the following code to set up my FBO: GLuint frameBufferID; glGenFramebuffers(1, &frameBufferID); glBindFramebuffer(GL_FRAMEBUFFER, frameBufferID); glGenTextures(1, &coloursTextureID); glBindTexture(GL_TEXTURE_2D, coloursTextureID); glTexImage2D(GL_TEXTURE_2D,0,GL_RGB,SCREEN_WIDTH,SCREEN_HEIGHT,0,GL_RGB,GL_UNSIGNED_BYTE,NULL); glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_NEAREST); glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_NEAREST); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE); //Depth buffer setup GLuint depthrenderbuffer; glGenRenderbuffers(1, &depthrenderbuffer); glBindRenderbuffer(GL_RENDERBUFFER, depthrenderbuffer); glRenderbufferStorage(GL_RENDERBUFFER, GL_DEPTH_COMPONENT24, SCREEN_WIDTH,SCREEN_HEIGHT); glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_RENDERBUFFER, depthrenderbuffer); glFramebufferTexture(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, coloursTextureID, 0); GLenum DrawBuffers[1] = {GL_COLOR_ATTACHMENT0}; glDrawBuffers(1, DrawBuffers); // if(glCheckFramebufferStatus(GL_FRAMEBUFFER) != GL_FRAMEBUFFER_COMPLETE) return false; Thank you so much for any help :)

• Texture not rendering in correct order in xna 4?

  - by user1090751

  I am making a simple board game. In the game there is a fixed background called myTexture and others are textureGoat and textureTiger whicha are to be placed on top of the background(myTexture). But i am having problem that fourth and fifth component is not displaying however, the sixth component( i.e. myTexture) is appearing. Here is my code, please look at it protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.Green); // TODO: Add your drawing code here spriteBatch.Begin(SpriteSortMode.BackToFront, BlendState.AlphaBlend); //placing tiger spriteBatch.Draw(textureTiger, new Rectangle(22, 25, 50, 50), Color.White);//first component spriteBatch.Draw(textureTiger, new Rectangle(22, 407, 50, 50), Color.White);//second component spriteBatch.Draw(textureTiger, new Rectangle(422, 25, 50, 50), Color.White);//third component spriteBatch.Draw(textureTiger, new Rectangle(422, 407, 50, 50), Color.White);//fourth component //placing goat spriteBatch.Draw(textureGoat, new Rectangle(125, 110, 50, 50), Color.White);//fifth component //placing background spriteBatch.Draw(myTexture, new Rectangle(0, 0, 500, 500), Color.White);//sixth component spriteBatch.End(); base.Draw(gameTime); }

• Need to produce an animated texture of Water where each image tiles in all directions

  - by ProfVersaggi

  I need to produce a 2D 'animated' texture of "water" for a game in which each image tiles in 'all' directions, much like those produced by the Caustics Generator, but with the power and flexibility of something the likes of Blender. The final result from Caustics Generator is 32 images that are actually animated such that when the full 32 images are played in a loop they will seamlessly loop forever. They will not only loop in time, but each image also tile in all directions. This is nice, but it comes in only one flavor so to speak. I'd like to accomplish the same thing with a Blender type tool, and I have actually gotten to the point where I generate the X number of images, but they do not tile in 'all' directions, nor are they slightly animated. I've tried Blender texture animations using offsets but with only limited success. Does anyone know of how to (or of a tool) which will animate textures such that they tile in all (4) directions? Many thanks in advance ....

• GameStateManagement and inputs not being recognized

  - by Dave Voyles

  EDIT: I've removed a bit of code from the input class to make this more readable, and updated my StartScreen class, which is now at the bottom. I have the same issues though, but they are explained in my comments on the bottom of this page. It won't let me paste my additional code here (the format comes out crazy), so I've linked to pastebin with the code pastebin I've been trying to implement the MS provided GameStateManagement sample with my game, but it has proven a bit difficult. Really, I'm using Oneksoft's Starter Kit, which uses the MS provided sample, so they are identical, except for my splash screen. I'm able to get the splash screen to launch, where it informs the player to press A to advance the screen, but this doesn't seem to accept any of my inputs. I’ve also added Console.Writeline(“Pressing A”) under the IsMenuPressed method in Input.cs to verify that it is getting called, but for some reason it is constantly spamming my log, rather than just appearing each time I press it. Not sure why this is happening. I have a bit too much code to post it all here, so I’ve attached a link to my .rar with my classes, but I’ll also leave a bit here which I thinkmay be applicable. https://www.dropbox.com/sh/6ek4uru2jc2ch0k/JTeBWN_3PQ What do you guys think the issue is? namespace Pong { public class Input { public const int MaxInputs = 4; public readonly KeyboardState[] CurrentKeyboardState; public readonly GamePadState[] CurrentGamePadState; public KeyboardState[] LastKeyboardState; public GamePadState[] LastGamePadState; public readonly bool[] GamePadWasConnected; public Input() { // Get input state CurrentKeyboardState = new KeyboardState[MaxInputs]; CurrentGamePadState = new GamePadState[MaxInputs]; // Preserving last states to check for isKeyUp events LastKeyboardState = CurrentKeyboardState; LastGamePadState = CurrentGamePadState; } /// <summary> /// Checks for a "menu select" input action. /// The controllingPlayer parameter specifies which player to read input for. /// If this is null, it will accept input from any player.

• How can I improve the "smoothness" of a 2D side-scrolling iPhone game?

  - by MrDatabase

  I'm working on a relatively simple 2D side-scrolling iPhone game. The controls are tilt-based. I use OpenGL ES 1.1 for the graphics. The game state is updated at a rate of 30 Hz... And the drawing is updated at a rate of 30 fps (via NSTimer). The smoothness of the drawing is ok... But not quite as smooth as a game like iFighter. What can I do to improve the smoothness of the game? Here are the potential issues I've briefly considered: I'm varying the opacity of up to 15 "small" (20x20 pixels) textures at a time... Apparently varying the opacity in this manner can degrade drawing performance I'm rendering at only 30 fps (via NSTimer)... Perhaps 2D games like iFighter are rendered at a higher frame rate? Perhaps the game state could be updated at a faster rate? Note the acceleration vales are updated at 100 Hz... So I could potentially update part of the game state at 100 hz All of my textures are PNG24... Perhaps PNG8 would help (due to smaller size etc)

• Will we see a trend of "3d" games coming up in the near future?

  - by Vish

  I've noticed that the trend of movies is diving into the world of movies with 3-dimensional camera.For me it provoked a thought as if it was the same feeling people got when they saw a colour movie for the first time, like in the transition from black and white to colour it is a whole new experience. For the first time we are experiencing the Z(depth) factor and I really mean when I said "experiencing". So my question is or maybe if not a question, but Is there a possibility of a genre of 3d camera games upcoming?

• why specular light is not running?

  - by nkint

  hi, i'm on JOGL this is my method for lighting: private void lights(GL gl) { float[] LightPos = {0.0f, 0.0f, -1.0f, 1.0f}; float[] LightAmb = {0.2f, 0.2f, 0.2f, 1.0f}; float[] LightDif = {0.6f, 0.6f, 0.6f, 1.0f}; float[] LightSpc = {0.9f, 0.9f, 0.9f, 1.0f}; gl.glLightfv(GL.GL_LIGHT1, GL.GL_POSITION, LightPos, 0); gl.glLightfv(GL.GL_LIGHT1, GL.GL_AMBIENT, LightAmb, 0); gl.glLightfv(GL.GL_LIGHT1, GL.GL_DIFFUSE, LightDif, 0); gl.glLightfv(GL.GL_LIGHT1, GL.GL_SPECULAR, LightSpc, 0); gl.glLightfv(GL.GL_LIGHT0, GL.GL_SPECULAR, LightSpc, 0); gl.glEnable(GL.GL_LIGHT0); gl.glEnable(GL.GL_LIGHT1); gl.glShadeModel(GL.GL_SMOOTH); gl.glEnable(GL.GL_LIGHTING); } and i see my objects flat, no specular light.. any ideas? ps. to render my objects: gl.glColor3f(1f,0f,0f); gl.glBegin(GL.GL_TRIANGLES); for(Triangle t : tubeModel.getTriangles()) { gl.glVertex3f(t.v1.x, t.v1.y, t.v1.z); gl.glVertex3f(t.v2.x, t.v2.y, t.v2.z); gl.glVertex3f(t.v3.x, t.v3.y, t.v3.z); } gl.glEnd();

• Collision detection - player gets stuck in platform when jumping

  - by Sun

  So I'm having some problems with my collision detection with my platformer. Take the image below as an example. When I'm running right I am unable to go through the platform, but when I hold my right key and jump, I end up going through the object as shown in the image, below is the code im using: if(shapePlatform.intersects(player.getCollisionShape())){ Vector2f vectorSide = new Vector2f(shapePlatform.getCenter()[0] - player.getCollisionShape().getCenter()[0], shapePlatform.getCenter()[1] - player.getCollisionShape().getCenter()[1]); player.setVerticleSpeed(0f); player.setJumping(false); if(vectorSide.x > 0 && !(vectorSide.y > 0)){ player.getPosition().set(player.getPosition().x-3, player.getPosition().y); }else if(vectorSide.y > 0){ player.getPosition().set(player.getPosition().x, player.getPosition().y); }else if(vectorSide.x < 0 && !(vectorSide.y > 0)){ player.getPosition().set(player.getPosition().x+3, player.getPosition().y); } } I'm basically getting the difference between the centre of the player and the centre of the colliding platform to determine which side the player is colliding with. When my player jumps and walks right on the platform he goes right through. The same can also be observed when I jump on the actual platform, should I be resetting the players y in this situation?

• Adapting Javascript game for mobile

  - by Cardin

  I'm currently developing a Javascript web game for desktop users. It is a sort of tower-defense game that relies on mouse input only, developed on canvas using EaselJS. In the future, or perhaps simultaneously, I would like to adapt the game for mobile devices. I can see at least 3 potential areas in shifting from desktop to mobile: 1. resolution size and UI rearrangement, 2. converting mouse events to touch events, 3. distribution as native app wrapper or mobile Web. What would be the best strategy to facilitate this desktop to mobile conversion? For example, should I try to code the game for both platforms, or port the game UI over to mobile by branching the code base. Should I just publish on the mobile Web or wrap the game in a native app framework? And if I were to code for both platforms using the same codebase, should I register both click and touch events, or remap click events to touch using dispatchEvent?

• Is there an AIR native extension to use GameCenter APIs for turn-based games?

  - by Phil

  I'm planning a turn based game using the iOS 5 GameCenter (GameKit) turn-based functions. Ideally I would program the game with AIR (I'm a Flash dev), but so far I can't seem to find any already available native extension that offers that (only basic GameCenter functions), so my questions are: Does anyone know if that already exists? And secondly how complex a task would it be to create an extension that does that? Are there any pitfalls I should be aware of etc.? ** UPDATE ** There does not seem a solution to the above from Adobe. For anyone who is interested check out the Adobe Gaming SDK. It contains a Game Center ANE which I've read contains options for multiplayer but not turn-based multiplayer, at least it's a start. Comes a bit late for me as I've already learned Obj-c!

  My son (15) has decided that he wants to pursue a career as a games programmer. I've said that he should get started now with a simple game. He has no programming experience yet, but I am a programmer (business apps, not games) so I can teach him programming, but what would be a good platform for him to start on? Initially I'm looking for something that can provide quick results, to keep his enthusiasm up. What would you suggest?

• UDK : UTWeap_RocketLauncher gift CreateInventory: Any idea why this does not work properly?

  I am giving the player an instanced class of UTWeap_RocketLauncher in an instance of UTGame. PlayerPawn.CreateInventory(class'FobikRocketLauncher',false); // Does not work PlayerPawn.CreateInventory(class'FobikLinkGun',false); // Works Even if I give the original class (eg. UTWeap_RocketLauncher) it does not actually show up. However if I do a "GiveWeapons" cheat, I get it just fine. It also works if I had code it into the map. - But UTWeap_LinkGun works fine either way. Any ideas? It shows the default ammo amount, and the icon on the HUD.

• Easy road from DisplayObject to Molehill?

  - by Bart van Heukelom

  I have a finished Flash game which is rendered using the built-in display tree, i.e. Bitmaps contained in Sprites (and a text here and there, few vector graphics, and one bitmap-filled shape). For extra performance, I'd like it to use Molehill for rendering, but that's not possible out of the box. What's the easiest way to make this game use Molehill when available, but fall back to the current method if it's not available?

• Rotating wheel with touch (adding momentum and slowing down the initial rate it can be moved

  - by Lewis

  I have a wheel control in a game which is setup like so: - (void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint location = [touch locationInView:[touch view]]; location = [[CCDirector sharedDirector] convertToGL:location]; if (CGRectContainsPoint(wheel.boundingBox, location)) { CGPoint firstLocation = [touch previousLocationInView:[touch view]]; CGPoint location = [touch locationInView:[touch view]]; CGPoint touchingPoint = [[CCDirector sharedDirector] convertToGL:location]; CGPoint firstTouchingPoint = [[CCDirector sharedDirector] convertToGL:firstLocation]; CGPoint firstVector = ccpSub(firstTouchingPoint, wheel.position); CGFloat firstRotateAngle = -ccpToAngle(firstVector); CGFloat previousTouch = CC_RADIANS_TO_DEGREES(firstRotateAngle); CGPoint vector = ccpSub(touchingPoint, wheel.position); CGFloat rotateAngle = -ccpToAngle(vector); CGFloat currentTouch = CC_RADIANS_TO_DEGREES(rotateAngle); wheelRotation += (currentTouch - previousTouch) * 0.6; //limit speed 0.6 } } Now once the user lets go of the wheel I want it to rotate back to where it was before but not without taking into account the momentum of the swipe the user has done. This is the bit I really can't get my head around. So if the swipe generates a lot of momentum then the wheel will carry on moving slightly in that direction until the overall force which pulls the wheel back to the starting position kicks in. Any ideas/code snippets?

• Who should respond to collision: Unit or projectile?

  - by aleguna

  In an RTS if a projectile hits a unit. Who should handle the collision? If projectile handles the collision, it must be aware of all possible types of units, to know what damage to inflict. For example a bullet will likely kill a human, but it will do nothing to a tank. The same goes if unit handles a collision. So either way one of them should be aware of all possible types of the other. Of course the 'true' way would be to do full physics simulation, but that's not an option for an RTS with 1000s of units and projectiles... So what are the common practicies in this regards?

• Drawing flaming letters in 3d on OpenGL ES 2.0

  - by Chiquis

  I am a bit confused about how to achieve this. What i want is to "draw with flames". I have achieved this with textures successfully, but now my concern is about doing this with particles to achieve the flaming effect. Am I supposed to have a Path in where i should add many particle emitters along the path that will "be emitting flames"? I understand the concept for 2d, but for 3d are the particles (that are quads) always supposed to be facing the user? Edit: Something else im worried about is the performance hit that will occur by having that many particle emitters, because there can be many letters and drawings at the same time. And each of these elements will have many particle emitters.

• Failing Screen Resize Method

  - by StrongJoshua

  So I want my game to draw to a specific "optimal" size and then be stretched to fit screens that are a different size. I'm using LibGDX and figured that I could just draw everything to a FrameBuffer and then resize that buffer to the appropriate size when drawing it to the actual display. However, my method does not work, it just results in a black screen with the top right quarter of the screen white.Intermediary is the FBO, interMatrix is a Matrix4 object, and camera is an OrthographicCamera. @Override public void render() { // update actors currentStage.act(); //render to intermediary buffer batch.setProjectionMatrix(interMatrix); intermediary.begin(); batch.begin(); currentStage.draw(); batch.flush(); intermediary.end(); //resize to actual width and height Sprite s = new Sprite(intermediary.getColorBufferTexture()); s.flip(true, false); batch.setProjectionMatrix(camera.combined); batch.draw(s.getTexture(), 0, 0, width, height); batch.end(); } These are the constructors for the above mentioned objects (GAME_WIDTH and HEIGHT are the "optimal" settings, width and height are the actual sizes, which are the same when running on desktop). intermediary = new FrameBuffer(Format.RGBA8888, GAME_WIDTH, GAME_HEIGHT, false); interMatrix = new Matrix4(); camera = new OrthographicCamera(width, height); interMatrix.setToOrtho2D(0, 0, GAME_WIDTH, GAME_HEIGHT); Is there a better way of doing this or can is this a viable option and how do I fix what I have?
