  • Can i change the order of these OpenGL / Win32 calls?

    - by Adam Naylor
    I've been adapting the NeHe ogl/win32 code to be more object orientated and I don't like the way some of the calls are structured. The example has the following pseudo structure: Register window class Change display settings with a DEVMODE Adjust window rect Create window Get DC Find closest matching pixel format Set the pixel format to closest match Create rendering context Make that context current Show the window Set it to foreground Set it to having focus Resize the GL scene Init GL The points in bold are what I want to move into a rendering class (the rest are what I see being pure win32 calls) but I'm not sure if I can call them after the win32 calls. Essentially what I'm aiming for is to encapsulate the Win32 calls into a Platform::Initiate() type method and the rest into a sort of Renderer::Initiate() method. So my question essentially boils down to: "Would OpenGL allow these methods to be called in this order?" Register window class Adjust window rect Create window Get DC Show the window Set it to foreground Set it to having focus Change display settings with a DEVMODE Find closest matching pixel format Set the pixel format to closest match Create rendering context Make that context current Resize the GL scene Init GL (obviously passing through the appropriate window handles and device contexts.) Thanks in advance.

  • How should I access frame buttons from a controller in an MVC approach?

    - by Loris
    I'm developing an italian card game using the mvc pattern. I have the class GameFrame that contains the view. The user's card are buttons (JButton objects). I have 3 controllers: GameController: to control the game in general. Contains the game loop. HumanPlayerController: to control the user input ComputerPlayerController: contains the AI of the computer PlayerController: is an interface with the makeTurn() method. It's implemented by HumanP.C. and ComputerP.C. HumanPlayerController implements ActionListener too. But what is the right way to access to the GameFrame buttons? I need it for understand which card was chosen. GameFrame and HumanPlayerController are in different packages. Should i make the JButtons public?

  • How access PhysicalMaterial from Actor Class?

    - by EmAdpres
    I use Projectile for my weapon system and UDKProjectile has two main function to handle Hit of projectiles(=bullet of my weapon): simulated function ProcessTouch(Actor Other, Vector HitLocation, Vector HitNormal) // For Actors simulated event HitWall(vector HitNormal, actor Wall, PrimitiveComponent WallComp) // Everything except Actors ( I guess) the first method, the function just give me the actor which I hit and my question is How I can get that actor's physical material by first parameter ( Other ), in order to make a proper react about it ( for example a proper Sound of collide ) ... A tricky (but hateful ) way which I knew works is, make a Trace from a little back of that actor to that actor, and use HitInfo parameter which include physical Material ! But there should be a more standard way !

  • OpenGL loading functions error [on hold]

    - by Ghilliedrone
    I'm new to OpenGL, and I bought a book on it for beginners. I finished writing the sample code for making a context/window. I get an error on this line at the part PFNWGLCREATECONTEXTATTRIBSARBPROC, saying "Error: expected a ')'": typedef HGLRC(APIENTRYP PFNWGLCREATECONTEXTATTRIBSARBPROC)(HDC, HGLRC, const int*); Replacing it or adding a ")" makes it error, but the error disappears when I use the OpenGL headers included in the books CD, which are OpenGL 3.0. I would like a way to make this work with the newest gl.h/wglext.h and without libraries. Here's the rest of the class if it's needed: #include <ctime> #include <windows.h> #include <iostream> #include <gl\GL.h> #include <gl\wglext.h> #include "Example.h" #include "GLWindow.h" typedef HGLRC(APIENTRYP PFNWGLCREATECONTEXTATTRIBSARBPROC)(HDC, HGLRC, const int*); PFNWGLCREATECONTEXTATTRIBSARBPROC wglCreateContextAttribsARB = NULL; bool GLWindow::create(int width, int height, int bpp, bool fullscreen) { DWORD dwExStyle; //Window Extended Style DWORD dwStyle; //Window Style m_isFullscreen = fullscreen;//Store the fullscreen flag m_windowRect.left = 0L; m_windowRect.right = (long)width; m_windowRect.top = 0L; m_windowRect.bottom = (long)height;//Set bottom to height // fill out the window class structure m_windowClass.cbSize = sizeof(WNDCLASSEX); m_windowClass.style = CS_HREDRAW | CS_VREDRAW; m_windowClass.lpfnWndProc = GLWindow::StaticWndProc; //We set our static method as the event handler m_windowClass.cbClsExtra = 0; m_windowClass.cbWndExtra = 0; m_windowClass.hInstance = m_hinstance; m_windowClass.hIcon = LoadIcon(NULL, IDI_APPLICATION); // default icon m_windowClass.hCursor = LoadCursor(NULL, IDC_ARROW); // default arrow m_windowClass.hbrBackground = NULL; // don't need background m_windowClass.lpszMenuName = NULL; // no menu m_windowClass.lpszClassName = (LPCWSTR)"GLClass"; m_windowClass.hIconSm = LoadIcon(NULL, IDI_WINLOGO); // windows logo small icon if (!RegisterClassEx(&m_windowClass)) { MessageBox(NULL, (LPCWSTR)"Failed to register window class", NULL, MB_OK); return false; } if (m_isFullscreen)//If we are fullscreen, we need to change the display { DEVMODE dmScreenSettings; //Device mode memset(&dmScreenSettings, 0, sizeof(dmScreenSettings)); dmScreenSettings.dmSize = sizeof(dmScreenSettings); dmScreenSettings.dmPelsWidth = width; //Screen width dmScreenSettings.dmPelsHeight = height; //Screen height dmScreenSettings.dmBitsPerPel = bpp; //Bits per pixel dmScreenSettings.dmFields = DM_BITSPERPEL | DM_PELSWIDTH | DM_PELSHEIGHT; if (ChangeDisplaySettings(&dmScreenSettings, CDS_FULLSCREEN) != DISP_CHANGE_SUCCESSFUL) { MessageBox(NULL, (LPCWSTR)"Display mode failed", NULL, MB_OK); m_isFullscreen = false; } } if (m_isFullscreen) //Is it fullscreen?

  • Can DrawIndexedPrimitives() be used for drawing a loaded model mesh-wise?

    - by Afzal
    I am using DrawIndexedPrimitives() for drawing a loaded 3D model by drawing each mesh part, but this process makes my application very slow. This is perhaps because of a very large number of vertex/index buffer data created in video memory. That is why I am looking for a way to use the same method for each model mesh instead. The problem is that I don't know how I will set the textures of that mesh. Can anyone offer me some guidance?

  • How to tile multiple procedurally generated textures?

    - by Burhuc
    I'm trying to develop a procedural tile generator for a game, mostly for the ground tiles, instead of using "hand-drawn" tiles. To achieve this I'm using Perlin noise and a sine wave with multiple parameters, which already gives me pretty nice results. I don't want to generate 1 tile and repeat that one forever for one ground type, but I want to avoid recurrences, so I'm generating n different tiles. The problem I'm having now is that I want to tile the generated textures (smooth transitions). At the moment I have this: 4 256x256 textures. I thought a simple method would be to just add the positions of the different tiles to the noise generation algorithm, so that, when creating the 4 256x256 textures, it would behave like it would create a 512x512 texture, but that somehow didn't work as intented. So how can I tile those textures?

  • Trying to create a sphere in UDK on which I can stand

    - by Dave
    Trying to build a globe in UDK, but when I do (create a sphere), my player falls straight through it. How do I make a sphere that I can walk on? Every other shape (cube, cone...etc) work just fine. -- Edit: Specifically, I want to build a CSG/Brush sphere, not a mesh sphere. It appears to work just fine if I set the "sphere exptrapolation" to 1 or 2, but if I bump it up to 3 or higher, I fall right through. I literally created 2 spheres next to each other, one set at "2" and one at "3" - I can walk from the top of the "2" sphere and jump onto the "3" sphere, but I fall right through it.

  • How to avoid circular dependencies between Player and World?

    - by futlib
    I'm working on a 2D game where you can move up, down, left and right. I have essentially two game logic objects: Player: Has a position relative to the world World: Draws the map and the player So far, World depends on Player (i.e. has a reference to it), needing its position to figure out where to draw the player character, and which portion of the map to draw. Now I want to add collision detection to make it impossible for the player to move through walls. The simplest way I can think of is to have the Player ask the World if the intended movement is possible. But that would introduce a circular dependency between Player and World (i.e. each holds a reference to the other), which seems worth avoiding. The only way I came up with is to have the World move the Player, but I find that somewhat unintuitive. What is my best option? Or is avoiding a circular dependency not worth it?

  • Correcting Lighting in Stencil Reflections

    - by Reanimation
    I'm just playing around with OpenGL seeing how different methods of making shadows and reflections work. I've been following this tutorial which describes using GLUT_STENCIL's and MASK's to create a reasonable interpretation of a reflection. Following that and a bit of tweaking to get things to work, I've come up with the code below. Unfortunately, the lighting isn't correct when the reflection is created. glPushMatrix(); plane(); //draw plane that reflection appears on glColorMask(GL_FALSE, GL_FALSE, GL_FALSE, GL_FALSE); glDepthMask(GL_FALSE); glEnable(GL_STENCIL_TEST); glStencilFunc(GL_ALWAYS, 1, 0xFFFFFFFF); glStencilOp(GL_REPLACE, GL_REPLACE, GL_REPLACE); plane(); //draw plane that acts as clipping area for reflection glColorMask(GL_TRUE, GL_TRUE, GL_TRUE, GL_TRUE); glDepthMask(GL_TRUE); glStencilFunc(GL_EQUAL, 1, 0xFFFFFFFF); glStencilOp(GL_KEEP, GL_KEEP, GL_KEEP); glDisable(GL_DEPTH_TEST); glPushMatrix(); glScalef(1.0f, -1.0f, 1.0f); glTranslatef(0,2,0); glRotatef(180,0,1,0); sphere(radius, spherePos); //draw object that you want to have a reflection glPopMatrix(); glEnable(GL_DEPTH_TEST); glDisable(GL_STENCIL_TEST); sphere(radius, spherePos); //draw object that creates reflection glPopMatrix(); It looked really cool to start with, then I noticed that the light in the reflection isn't correct. I'm not sure that it's even a simple fix because effectively the reflection is also a sphere but I thought I'd ask here none-the-less. I've tried various rotations (seen above the first time the sphere is drawn) but it doesn't seem to work. I figure it needs to rotate around the Y and Z axis but that's not correct. Have I implemented the rotation wrong or is there a way to correct the lighting?

  • Server-side Architecture for Online Game

    - by Draiken
    basically I have a game client that has communicate with a server for almost every action it takes, the game is in Java (using LWJGL) and right now I will start making the server. The base of the game is normally one client communicating with the server alone, but I will require later on for several clients to work together for some functionalities. I've already read how authentication server should be sepparated and I intend on doing it. The problem is I am completely inexperienced in this kind of server-side programming, all I've ever programmed were JSF web applications. I imagine I'll do socket connections for pretty much every game communication since HTML is very slow, but I still don't really know where to start on my server. I would appreciate reading material or guidelines on where to start, what architecture should the game server have and maybe some suggestions on frameworks that could help me getting the client-server communication. I've looked into JNAG but I have no experience with this kind of thing, so I can't really tell if it is a solid and good messaging layer. Any help is appreciated... Thanks ! EDIT: Just a little more information about the game. It is intended to be a very complex game with several functionalities, making some functionalities a "program" inside the program. It is not an usual game, like FPS or RPG but I intend on having a lot of users using these many different "programs" inside the game. If I wasn't clear enough, I'd really appreciate people that have already developed games with java client/server architecture, how they communicated, any frameworks, apis, messaging systems, etc. It is not a question of lack of knowledge of language, more a question for advice, so I don't end up creating something that works, but in the later stages will have to be rewriten for any kind of limiting reason. PS: sorry if my english is not perfect...

  • Unity, changing gravity game & stopping character when he hit a wall.

    - by Sylario
    i am currently working on a 2d puzzle game in the unity engine. One of the aspect of this game is the possibility to rotate the level of 90°. It also rotate the gravity. The main character is not directly controlled by the player, but instead fall when the level is rotated. When the main character hit a wall, he should stop to move. If i do not stop it, it kind of blink ans shake against the wall. To stop it i detect collision and depending on the current rotation state, the player will stop at "vertical" or "horizontal" tags when a OnCollisonEnter occurs. I must do that because when the player fall on his relative ground, He must not stop like if he had touch a wall. My problem is the 'side' of platform, or the 'top' of wall, they use the same tag and thus do not give the correct tag to my character. I tried to put a very small invisible box on top/side of elements but the collision occurs nevertheless. It seems when the player falls and hit something he go through a bit before being replaced at correct position by unity. Is there a way : 1 ) to doesn't stop my character but to make it appear immobile on screen 2 ) To detect a "i cannot move anymore" collision other than by using collision?

  • Debugging-Setting Consoles in Games

    - by ShrimpCrackers
    Right now I have the graphical and input portions of a console for my game (command parsing hasn't been implemented yet). I was wondering how you would go about making changes to properties in game objects. For example, if I typed in the console: skeletonMonster maxHP 20 That would change all of the existing in-game skeletons' max hit points to 20. After you parse this information what are some ways to change the value? How can I change the variable(s) without violating information hiding? I'd like to implement this so I don't have to change variables in the code and recompile every time while playtesting.

Model and texture a vehicle and two different obstacles Build a scene graph in Panda with a plane, the vehicle, several copies of each of the obstacles, and (at least) a direction light Program vehicle movement, constrained to a plane (no terrain) Working headlights Vehicle collides with obstacles How do I attach a light source to a model? I'm assuming this is done in Panda3D but I'm sufficiently new to this that I wouldn't be astonished to hear it's part of the model.

  • HTML5 clicking objects in canvas

    - by Dave
    I have a function in my JS that gets the user's mouse click on the canvas. Now lets say I have a random shape on my canvas (really its a PNG image which is rectangular) but i don't want to include any alpha space. My issue lies with lets say i click some where and it involves a pixel of one of the images. The first issue is how do you work out the pixel location is an object on the map (and not the grass tiles behind). Secondly if i clicked said image, if each image contains its own unique information how do you process the click to load the correct data. Note I don't use libraries I personally prefer the raw method. Relying on libraries doesn't teach me much I find.

  • How can i create sprite sheet from 3d model (3D studio max)

    - by OopsUser
    I built simple 3D model of a car, with simple animation in which it's wheels are turning. Now i want to create a sprite sheet, the only way i know how to do it, is to render manually 20 frames from the from, then combine them to a strip manually, then rotate it by 10 degrees, render 20 frames of animation again and combine them to a strip... Is there a way to do it automatically ? With out rotating the scene manually and render it and combining .. it's a lot of work, takes more time then the modelling itself... Thanks

    I'm trying to figure out the best design here, and I can see multiple approaches, but none that seems "right." There are three relevant classes here: Base, TradingPost, and Resource. Each Base has a TradingPost which can offer various Resources depending on the Base's tech level. Where is the right place to store the minimum tech level a base must possess to offer any given resource? A database seems like overkill. Putting it in each subclass of Resource seems wrong--that's not an intrinsic property of the Resource. Do I have a mediating class, and if so, how does it work? It's important that I not be duplicating code; that I have one place where I set the required tech level for a given item. Essentially, where does this data belong? P.S. Feel free to change the title; I struggled to come up with one that fits.

  • Simple 2 player server

    - by Sourabh Lal
    I have recently started learning javascript and html and have developed simple 2 player games such as tick-tack-toe, battleship, and dots&boxes. However these 2 player games can only be played on one computer (i.e. the 2 players must sit together) However, I want to modify this so that one can play with a friend on a different computer. Any suggestions on how this is possible? Also since I am a beginner please do not assume that I know all the jargon.

  • Why is C++ used for game engines? How about its future in game engines?

    - by kasperov
    C++, as I have seen, is being heavily used in 3d video game engines.... Is it because of the performance issues, legecy code or libraries such as DriverX? If performance, libraries and code infrastructure are the reasons, dosen't that make C++ indispensible, at least for game engines? (ie, we have no other option even in the very distant future). I asked this because, I have the right to know the upcomming future trends in game engines.

  • One-way platform collision

    - by TheBroodian
    I hate asking questions that are specific to my own code like this, but I've run into a pesky roadblock and could use some help getting around it. I'm coding floating platforms into my game that will allow a player to jump onto them from underneath, but then will not allow players to fall through them once they are on top, which require some custom collision detection code. The code I have written so far isn't working, the character passes through it on the way up, and on the way down, stops for a moment on the platform, and then falls right through it. Here is the code to handle collisions with floating platforms: protected void HandleFloatingPlatforms(Vector2 moveAmount) { //if character is traveling downward. if (moveAmount.Y > 0) { Rectangle afterMoveRect = collisionRectangle; afterMoveRect.Offset((int)moveAmount.X, (int)moveAmount.Y); foreach (World_Objects.GameObject platform in gameplayScreen.Entities) { if (platform is World_Objects.Inanimate_Objects.FloatingPlatform) { //wideProximityArea is just a rectangle surrounding the collision //box of an entity to check for nearby entities. if (wideProximityArea.Intersects(platform.CollisionRectangle) || wideProximityArea.Contains(platform.CollisionRectangle)) { if (afterMoveRect.Intersects(platform.CollisionRectangle)) { //This, in my mind would denote that after the character is moved, its feet have fallen below the top of the platform, but before he had moved its feet were above it... if (collisionRectangle.Bottom <= platform.CollisionRectangle.Top) { if (afterMoveRect.Bottom > platform.CollisionRectangle.Top) { //And then after detecting that he has fallen through the platform, reposition him on top of it... worldLocation.Y = platform.CollisionRectangle.Y - frameHeight; hasCollidedVertically = true; } } } } } } } } In case you are curious, the parameter moveAmount is found through this code: elapsed = (float)gameTime.ElapsedGameTime.TotalSeconds; float totalX = 0; float totalY = 0; foreach (Vector2 vector in velocities) { totalX += vector.X; totalY += vector.Y; } velocities.Clear(); velocity.X = totalX; velocity.Y = totalY; velocity.Y = Math.Min(velocity.Y, 1000); Vector2 moveAmount = velocity * elapsed;

  • How do I implement a selectable world map?

    - by Clay
    I want to have a selectable map of the world, preferably zoomable, in a cocos2d project. When I tap on a country, I want that country to be selected so that I can perform some other operations with it. It seems that the best approach would be to use a vector world map, but I'm unsure how to implement this with cocos2d. Other options include using map tiles, but it seems that still would require the implementation of country polygons for tap/click detection. Depending on user input, I want to add icons to various countries on the map. What is a good way to approach the implementation of this type of map?

  • Using Instance Nodes, worth it?

    - by Twitch
    I am making a 2d game where there are various environments with lots and lots of objects. There is a forest scene with like 1200 objects in total(trees mainly), of which around 100 are visible on the camera at any given time, as you move through the level. These are comprised of around 20 different kind of trees and other props. Each object is usually 2-6 triangles with a transparent texture. My developer asked me to replace each object in the scene with a node, and keeping only a minimal amount of actual objects which would be 300+ or so(?), since there are a few modified unique meshes. So he can instantiate the actual objects to keep the game light. Is this actually effective? And if so how much? I 've read about draw calls and such and I suppose that if I combine each texture (10 kinds of trees) in 1 mesh it will have the same effect?
