• In GLSL is it possible to offset vertices based on height map colour?

  - by Rob

  I am attempting to generate some terrain based upon a heightmap. I have generated a 32 x 32 grid and a corresponding height map - In my vertex shader I am trying to offset the position of the Y axis based upon the colour of the heightmap, white vertices being higher than black ones. //Vertex Shader Code #version 330 uniform mat4 modelMatrix; uniform mat4 viewMatrix; uniform mat4 projectionMatrix; uniform sampler2D heightmap; layout (location=0) in vec4 vertexPos; layout (location=1) in vec4 vertexColour; layout (location=3) in vec2 vertexTextureCoord; layout (location=4) in float offset; out vec4 fragCol; out vec4 fragPos; out vec2 fragTex; void main() { // Retreive the current pixel's colour vec4 hmColour = texture(heightmap,vertexTextureCoord); // Offset the y position by the value of current texel's colour value ? vec4 offset = vec4(vertexPos.x , vertexPos.y + hmColour.r, vertexPos.z , 1.0); // Final Position gl_Position = projectionMatrix * viewMatrix * modelMatrix * offset; // Data sent to Fragment Shader. fragCol = vertexColour; fragPos = vertexPos; fragTex = vertexTextureCoord; } However the code I have produced only creates a grid with none of the y vertices higher than any others. This is the C++ code that generates the grid and texture co-orientates which I believe to be correct as the texture is mapped to the grid, hence the white blob in the middle. The grid-lines are generated in the fragment shader, sorry for any confusion. I have tried multiplying the r value of hmColour by 1000 unfortunately that had no effect. The only other problem it could be is that the texture coordinate data is incorrect ? for (int z = 0; z < MAP_Z ; z++) { for(int x = 0; x < MAP_X ; x++) { //Generate Vertex Buffer vertexData[iVertex++] = float (x) * MAP_X; vertexData[iVertex++] = 0; vertexData[iVertex++] = -(float) (z) * MAP_Z; //Colour Buffer NOT NEEDED colourData[iColour++] = 255.0f; // R colourData[iColour++] = 1.0f; // G colourData[iColour++] = 0.0f; // B //Texture Buffer textureData[iTexture++] = (float ) x * (1.0f / MAP_X); textureData[iTexture++] = (float ) z * (1.0f / MAP_Z); } } The heightmap texture I am trying to use appears like so (without grid-lines). This is the corresponding fragment shader // Fragment Shader Code #version 330 uniform sampler2D hmTexture; layout (location=0) out vec4 fragColour; in vec2 fragTex; in vec4 pos; void main(void) { vec2 line = fragTex * 32; // Without Gridlines fragColour = texture(hmTexture,fragTex); // With grid lines // + mix(vec4(0.0, 0.0, 1.0, 0.0), vec4(1.0, 1.0, 1.0, 1.0), // smoothstep(0.05,fract(line.y), 0.99) * smoothstep(0.05,fract(line.x),0.99)); }

• Collision library for bullet hell in Python

  - by darkfeline

  I am making a bullet hell game in Python and am looking for a suitable collision library, taking the following into consideration: The library should do 2D polygon collision. It should be very fast. As a bullet hell game, I expect to do collision checks between hundreds, likely thousands of objects every frame at a consistent 60fps. Good documentation Permissive license (like MIT, not GPL) I am also considering writing my own library in C/C++ and wrapping with python ctypes in the event that no such library exists, though I do not have experience with collision detection algorithms, so I am not sure if this would be more trouble than it's worth. Could someone provide some guidance on this matter?

• Efficiently checking input and firing events

  - by Jim

  I'm writing an InputHandler class in XNA, and there are several different keys considered valid input (all of type Microsoft.XNA.Framework.Input.Keys). For each key, I have three events: internal event InputEvent XYZPressed; internal event InputEvent XYZHeld; internal event InputEvent XYZReleased; where XYZ is the name of the Keys object representing that key. To fire these events, I have the following for each key: if (Keyboard.GetState().IsKeyDown(XYZ)) { if (PreviousKeyState.IsKeyDown(XYZ)) { if (XYZHeld != null) XYZHeld(); } else { if (XYZPressed != null) XYZPressed(); } } else if (PreviousKeyState.IsKeyDown(XYZ)) { if (XYZReleased != null) XYZReleased(); } However, this is a lot of repeated code (the above needs to be repeated for each input key). Aside from being a hassle to write, if any keys are added to/removed from the keys (if functionality is added/removed), a new section needs to be added (or an existing one removed). Is there a cleaner way to do this? Perhaps something along the lines of foreach key check which state it's in fire this key's event for that state where the code does the foreach (automatically checking exactly those keys that "exist") rather than the coder?

• Performance of pixel shaders vs. SpriteBatch: XNA

  - by ashes999

  Precondition: I read this question/answer about using shaders, or spritebatch, to render and mark a sprite. I need to do something like that. I also have a 2D lighting PoC which I need to write. The way it will work will basically be something like: Draw all the sprites Draw lighting gradients to create a lighting texture Multiply/add the lighting texture to achieve different effects (I use multiple passes of add/multiply the lighting texture to achieve different effects.) My question is really about a generalization: can I say with certainty that pixel shaders are always faster than adding/multiplying textures to the SpriteBatch? Or that adding/multiplying is always faster? Or if it's not generalizable, how do I decide which approach to take, given that I can probably code either of them? (If it matters, I'm using MonoGame 3.0 beta for Windows games)

• Frameskipping in Android gameloop causing choppy sprites (Open GL ES 2.0)

  - by user22241

  I have written a simple 2d platform game for Android and am wondering how one deals with frame-skipping? Are there any alternatives? Let me explain further. So, my game loop allows for the rendering to be skipped if game updates and rendering do not fit into my fixed time-slice (16.667ms). This allows my game to run at identically perceived speeds on different devices. And this works great, things do run at the same speed. However, when the gameloop skips a render call for even one frame, the sprite glitches. And thinking about it, why wouldn't it? You're seeing a sprite move say, an average of 10 pixels every 1.6 seconds, then suddenly, there is a pause of 3.2ms, and the sprite then appears to jump 20 pixels. When this happens 3 or 4 times in close succession, the result is very ugly and not something I want in my game. Therfore, my question is how does one deal with these 'pauses' and 'jumps' - I've read every article on game loops I can find (see below) and my loops are even based off of code from these articles. The articles specifically mention frame skipping but they don't make any reference to how to deal with visual glitches that result from it. I've attempted various game-loops. My loop must have a mechanism in-place to allow rendering to be skipped to keep game-speed constant across multiple devices (or alternative, if one exists) I've tried interpolation but this doesn't eliminate this specific problem (although it looks like it may mitigate the issue slightly as when it eventually draws the sprite it 'moves it back' between the old and current positions so the 'jump' isn't so big. I've also tried a form of extrapolation which does seem to keep things smooth considerably, but I find it to be next to completely useless because it plays havoc with my collision detection (even when drawing with a 'display only' coordinate - see extrapolation-breaks-collision-detection) I've tried a loop that uses Thread.sleep when drawing / updating completes with time left over, no frame skipping in this one, again fairly smooth, but runs differently on different devices so no good. And I've tried spawning my own, third thread for logic updates, but this, was extremely messy to deal with and the performance really wasn't good. (upon reading tons of forums, most people seem to agree a 2 thread loops ( so UI and GL threads) is safer / easier). Now if I remove frame skipping, then all seems to run nice and smooth, with or without inter/extrapolation. However, this isn't an option because the game then runs at different speeds on different devices as it falls behind from not being able to render fast enough. I'm running logic at 60 Ticks per second and rendering as fast as I can. I've read, as far as I can see every article out there, I've tried the loops from My Secret Garden and Fix your timestep. I've also read: Against the grain deWITTERS Game Loop Plus various other articles on Game-loops. A lot of the others are derived from the above articles or just copied word for word. These are all great, but they don't touch on the issues I'm experiencing. I really have tried everything I can think of over the course of a year to eliminate these glitches to no avail, so any and all help would be appreciated. A couple of examples of my game loops (Code follows): From My Secret Room public void onDrawFrame(GL10 gl) { //Rre-set loop back to 0 to start counting again loops=0; while(System.currentTimeMillis() > nextGameTick && loops < maxFrameskip) { SceneManager.getInstance().getCurrentScene().updateLogic(); nextGameTick += skipTicks; timeCorrection += (1000d / ticksPerSecond) % 1; nextGameTick += timeCorrection; timeCorrection %= 1; loops++; } extrapolation = (float)(System.currentTimeMillis() + skipTicks - nextGameTick) / (float)skipTicks; render(extrapolation); } And from Fix your timestep double t = 0.0; double dt2 = 0.01; double currentTime = System.currentTimeMillis()*0.001; double accumulator = 0.0; double newTime; double frameTime; @Override public void onDrawFrame(GL10 gl) { newTime = System.currentTimeMillis()*0.001; frameTime = newTime - currentTime; if ( frameTime > (dt*5)) //Allow 5 'skips' frameTime = (dt*5); currentTime = newTime; accumulator += frameTime; while ( accumulator >= dt ) { SceneManager.getInstance().getCurrentScene().updateLogic(); previousState = currentState; accumulator -= dt; } interpolation = (float) (accumulator / dt); render(interpolation); }

• Isometric drawing "Not Tile Stuff" on isometric map?

  - by Icebone1000

  So I got my isometric renderer working, it can draw diamond or jagged maps...Then I want to move on...How do I draw characters/objects on it in a optimal way? What Im doing now, as one can imagine, is traversing my grid(map) and drawing the tiles in a order so alpha blending works correctly. So, anything I draw in this map must be drawed at the same time the map is being drawn, with sucks a lot, screws your very modular map drawer, because now everything on the game (but the HUD) must be included on the drawer.. I was thinking whats the best approach to do this, comparing the position of all objects(not tile stuff) on the grid against the current tile being draw seems stupid, would it be better to add an id ON the grid(map)? this also seems terrible, because objects can move freely, not per tile steps (it can occupies 2 tiles if its between them, etc.) Dont know if matters, but my grid is 3D, so its not a plane with objects poping out, its a bunch of pilled cubes.

• How can a single script attached to multiple enemies provide separate behavior for each enemy?

  - by Syed

  I am making a TD game and now stucked at multiple enemies using same script. All is well with scripts attached with one enemy only. Problem is in running multiple enemies. Here is the overview. I have a Enemy object with which I have attached a 'RunEnemy' script. Flow of this script is: RunEnemy.cs: PathF p; p = gameObject.GetComponent<PathF>(); //PathF is a pathfinding algo which has 'search; function which returns a array of path from starting position PathList = p.search(starting position); //------------------------------- if(PathList != null) { //if a way found! if(moving forward) transform.Translate(someXvalue,0,0); //translates on every frame until next grid point else if(moving back) transform.Translate(0,someXvalue,0); ...and so on.. if(reached on next point) PathList = p.search(from this point) //call again from next grid point so that if user placed a tower enemy will run again on the returned path } Now I have attached this script and "PathF.cs" to a single enemy which works perfect. I have then made one more enemy object and attached both of these script to it as well, which is not working they both are overlapping movements. I can't understand why, I have attached these scripts on two different gameobjects but still their values change when either enemy changes its value. I don't want to go with a separate script for each enemy because there would be 30 enemies in a scene. How can I fix this problem?

• 5.1 sound in Unity3d 3.5

  - by N0xus

  I'm trying to implement 5.1 surround sound in my game. I've set Unity's AudioManager to a default of 5.1 surround and loaded in a 6 channel audio clip that should play a sound in each of the different audio spots. However, when I go to run my game, all I get is flat sound coming out of my front two speakers. Even then, these don't play the sound they should (front speaker should play "front speaker" right should play "right speaker" and so). Both speakers just end up playing the entire sound file. I've tried looking to see if there is a parameter that I have missed, but information on how to set up 5.1 sound in Unity is lacking (or my google skills aren't that good) and I can't get it to work as intended. Could someone please either tell me what I'm missing, or point me in the right direction? My audio source is situated at point (0, 0, 0) with my camera also being in the same point. I've moved about the scene but the same thing happens as I've already described.

• HTML5 point and click adventure game code structure with CreateJS

  - by user1612686

  I'm a programming beginner. I made a tiny one scene point and click adventure game to try to understand simple game logic and came up with this: CreateJS features prototypes for creating bitmap images, sprites and sounds objects. I create them and define their properties in a corresponding function (for example images(); spritesheets(), sounds()...). I then create functions for each animation sequence and "game level" functions, which handle user interactions and play the according animations and sounds for a certain event (when the level is complete, the current level function calls the next level function). And I end up with quite the mess. What would be the "standard (if something like that exists)" OOP approach to structure simple game data and interactions like that? I thought about making game.images, game.sprites, game.sounds objects, which contain all the game data with its properties using CreateJS constructors. game.spriteAnimations and game.tweenAnimations objects for sprite animations and tweens and a game.levelN object, which communicates with a game.interaction object, processing user interaction. Does this make any sense? How do you structure your simple game code? Thanks in advance!

• 2D Physics Engine to Handle Shapes Composed of Multiple Densities XNA

  - by Stupac

  The game I'm working on involves shapes that might be composed of multiple materials in a variety of ways. Let's just take for example a wooden rod with and sizable tip of iron or say a block composed of a couple triangles of stone and aluminum and small nugget of gold. The shapes and compositions will change from time to time, so I was wondering what engine I should use and how I might implement this feature? I've looked at Farseer 3, but I'm still trying to decipher the library by reading the source and the samples and wasn't sure if I was barking up the wrong tree. Thanks!

• Interpolation using a sprite's previous frame and current frame

  - by user22241

  Overview I'm currently using a method which has been pointed out to me is extrapolation rather than interolation. As a result, I'm also now looking into the possibility of using another method which is based on a sprite's position at it's last (rendered) frame and it's current one. Assuming an interpolation value of 0.5 this is, (visually), how I understand it should affect my sprite's position.... This is how I'm obtaining an inerpolation value: public void onDrawFrame(GL10 gl) { // Set/re-set loop back to 0 to start counting again loops=0; while(System.currentTimeMillis() > nextGameTick && loops < maxFrameskip) { SceneManager.getInstance().getCurrentScene().updateLogic(); nextGameTick += skipTicks; timeCorrection += (1000d / ticksPerSecond) % 1; nextGameTick += timeCorrection; timeCorrection %= 1; loops++; tics++; } interpolation = (float)(System.currentTimeMillis() + skipTicks - nextGameTick) / (float)skipTicks; render(interpolation); } I am then applying it like so (in my rendering call): render(float interpolation) { spriteScreenX = (spriteScreenX - spritePreviousX) * interpolation + spritePreviousX; spritePreviousX = spriteScreenX; // update and store this for next time } Results This unfortunately does nothing to smooth the movement of my sprite. It's pretty much the same as without the interpolation code. I can't get my head around how this is supposed to work and I honestly can't find any decent resources which explain this in any detail. My understanding of extrapolation is that when we arrive at the rendering call, we calculate the time between the last update call and the render call, and then adjust the sprite's position to reflect this time (moving the sprite forward) - And yet, this (Interpolation) is moving the sprite back, so how can this produce smooth results? Any advise on this would be very much appreciated. Edit I've implemented the code from OriginalDaemon's answer like so: @Override public void onDrawFrame(GL10 gl) { newTime = System.currentTimeMillis()*0.001; frameTime = newTime - currentTime; if ( frameTime > (dt*25)) frameTime = (dt*25); currentTime = newTime; accumulator += frameTime; while ( accumulator >= dt ) { SceneManager.getInstance().getCurrentScene().updateLogic(); previousState = currentState; t += dt; accumulator -= dt; } interpolation = (float) (accumulator / dt); render(); } Interpolation values are now being produced between 0 and 1 as expected (similar to how they were in my original loop) - however, the results are the same as my original loop (my original loop allowed frames to skip if they took too long to draw which I think this loop is also doing). I appear to have made a mistake in my previous logging, it is logging as I would expect it to (interpolated position does appear to be inbetween the previous and current positions) - however, the sprites are most definitely choppy when the render() skipping happens.

• Blender Object Appearing Gray when all Lights are Off

  - by celestialorb

  I have an issue with Blender where, when I turn my only light off (a sun lamp) and render the image my object appears gray rather than black (and thus, not appear to the camera). I can't figure out why this is happening. Here's what I just did in my scene: Added a new UV Sphere mesh (to make a total of two spheres), made it visible to the camera, turned off the sun lamp (by setting energy to 0), and rendered. The result I obtained is below. I discovered this when attempting to render the first sphere with a material/texture on it and it was too bright. The material on the spheres (which are different) are very basic, there's no emit, diffuse and specular are at default values. Could there be an issue with the way my camera is setup? Thanks in advance!

• HTML Javascript Hidden Object or Photo Hunt Game

  - by PeteT

  Is anyone aware of any example photo hunt/hidden object games either in HTML and Javascript or flash if necessary? I am having trouble finding one, I may be using the wrong words to search. Photo hunt being like the wheres wally/waldo books where you look for wally in a complex image until you find him. So if it were played on screen you would press the location of wally and it would either be correct or wrong, possibly timed. I am hoping to find one where you can just load in your own photos and specify some co-ordinates that match where the hidden object is. A spot the difference example may be useful as a starting point but I haven't found an example of either that is web based yet.

• Exporting .FBX model into XNA - unorthogonal bones

  - by Sweta Dwivedi

  I create a butterfly model in 3ds max with some basic animation, however trying to export it to .FBX format I get the following exception.. any idea how i can transform the wings to be orthogonal.. One or more objects in the scene has local axes that are not perpendicular to each other (non-orthogonal). The FBX plug-in only supports orthogonal (or perpendicular) axes and will not correctly import or export any transformations that involve non-perpendicular local axes. This can create an inaccurate appearance with the affected objects: -Right.Wing I have attached a picture for reference . . .

• Loading SpriteFont through a different class than Game.cs

  I am trying to load up a single SpriteFont to print some debug information. In our current game, we load up both Textures and Music through a ResourceManager.

• OpenGL texture on sphere

  - by Cilenco

  I want to create a rolling, textured ball in OpenGL ES 1.0 for Android. With this function I can create a sphere: public Ball(GL10 gl, float radius) { ByteBuffer bb = ByteBuffer.allocateDirect(40000); bb.order(ByteOrder.nativeOrder()); sphereVertex = bb.asFloatBuffer(); points = build(); } private int build() { double dTheta = STEP * Math.PI / 180; double dPhi = dTheta; int points = 0; for(double phi = -(Math.PI/2); phi <= Math.PI/2; phi+=dPhi) { for(double theta = 0.0; theta <= (Math.PI * 2); theta+=dTheta) { sphereVertex.put((float) (raduis * Math.sin(phi) * Math.cos(theta))); sphereVertex.put((float) (raduis * Math.sin(phi) * Math.sin(theta))); sphereVertex.put((float) (raduis * Math.cos(phi))); points++; } } sphereVertex.position(0); return points; } public void draw() { texture.bind(); gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); gl.glVertexPointer(3, GL10.GL_FLOAT, 0, sphereVertex); gl.glDrawArrays(GL10.GL_TRIANGLE_FAN, 0, points); gl.glDisableClientState(GL10.GL_VERTEX_ARRAY); } My problem now is that I want to use this texture for the sphere but then only a black ball is created (of course because the top right corner s black). I use this texture coordinates because I want to use the whole texture: 0|0 0|1 1|1 1|0 That's what I learned from texturing a triangle. Is that incorrect if I want to use it with a sphere? What do I have to do to use the texture correctly?

• Developing for iOS on Linux

  - by Jay

  I am looking for an engine or library to develop a game for iOS on Linux. High level, low level, GUI, no GUI, does not matter too much. I am really looking for anything. I'm not actually talking about deploying to iOS from Linux or anything like. I just want to do the bulk of the work on Linux, with minimal changes required to run it on iOS. Edit: YES, I do have access to a Mac, but it is limited. So I want to be able to work on the project on my regular Ubuntu box. Also, I am in the paid developer program, so I can deploy to iOS devices from the Mac.

• How do I limit the game loop?

  - by user1758938

  How do I make a game update at a consistent speed? For example, this would loop too fast: while(true) { GetInput(); Render(); } This just wont work (hard to explain): while(true) { GetInput(); Render(); Sleep(16); } How do I sync my game to a certain framerate and still have input and functions going at a consistent rate?

• Pygame Tile Based Character movement speed

  - by Ryan

  Thanks for taking the time to read this. Right now I'm making a really basic tile based game. The map is a large amount of 16x16 tiles, and the character image is 16x16 as well. My character has its own class that is an extension of the sprite class, and the x and y position is saved in terms of the tile position. To note I am fairly new to pygame. My question is, I am planning to have character movement restricted to one tile at a time, and I'm not sure how to make it so that, even if the player hits the directional key dozens of time quickly, (WASD or arrow keys) it will only move from tile to tile at a certain speed. How could I implement this generally with pygame? (Similar to game movement of like Pokemon or NexusTk). Edit: I should probably note that I want it so that the player can only end a movement in a tile. He couldn't stop moving halfway inbetween a tile for example. Thanks for your time! Ryan

• Graphics module: Am I going the right way?

  - by Paul

  I'm trying to write the graphics module of my engine. That is, this part of the code only provides an interface through which to load images, fonts, etc and draw them on the screen. It is also a wrapper for the library I'm using (SDL in this case). Here are the interfaces for my Image, Font and GraphicsRenderer classes. Please tell me if I'm going the right way. Image class Image { public: Image(); Image(const Image& other); Image(const char* file); ~Image(); bool load(const char* file); void free(); bool isLoaded() const; Image& operator=(const Image& other); private: friend class GraphicsRenderer; void* data_; }; Font class Font { public: Font(); Font(const Font& other); Font(const char* file, int ptsize); ~Font(); void load(const char* file, int ptsize); void free(); bool isLoaded() const; Font& operator=(const Font& other); private: friend class GraphicsRenderer; void* data_; }; GrapphicsRenderer class GraphicsRenderer { public: static GraphicsRenderer* Instance(); void blitImage(const Image& img, int x, int y); void blitText(const char* string, const Font& font, int x, int y); void render(); protected: GraphicsRenderer(); GraphicsRenderer(const GraphicsRenderer& other); GraphicsRenderer& operator=(const GraphicsRenderer& other); ~GraphicsRenderer(); private: void* screen_; bool initialize(); void finalize(); };

• Ideas for extending tic-tac-toe game?

  - by pimvdb

  I'm building a 3D tic-tac-toe game and this is what I've implemented so far: 3D renderer with texture mapping Playing against the computer Playing online (multiplayer) Now I'm a little lost what I could add. Obviously, tic-tac-toe isn't that exciting or advanced, but I just miss something to salt it a little bit. Therefore, could anyone please suggest some ideas that would be worth implementing? Thanks!
