  • How to end game properly in unity? [duplicate]

    - by user3889649
    This question already has an answer here: Why do I seem to lose control of my computer when full screen Unity game loses focus? 1 answer I have made a game in unity free. The game is functioning properly but if your computer receives any kind of notification, the game minimizes automatically and stops to work completely. Along with that, my computer freezes completely and I need to restart each time. Is there any solution to this problem in unity ?

  • Client side prediction/simulation Question

    - by Legendre
    I found a related question but it doesn't have what I needed. Client A sends input to move at T0. Server receives input at T1. All clients receive the change at T2. Question: With client-side prediction, client A would start moving at T0, client-side. All other clients receive the change at T2, so to them, client A only started moving at T2. If I understand correctly, client B will always see client A's past position and not his current position? How do I sync both client B and client A?

  • I Need Help With A Game (Well The API)! [closed]

    - by user1758938
    I'm not "sure" which API (or language) I should use for a little 3D FPS game I'm gonna make although I don't have helpers lol. Anyway I'm ok with Java, C# and C++ but I need a good setup (easy to use) with the tools I need to make the game. I tried things like XNA but I want to check other options first because I don't like how it makes a installer and stuff, it's really annoying. I Need A API That Can Do These Things: 3D Rendering Input Sound And If It's Not Too Much To Ask Some Cool Shaders, Dynamic Lighting And A 3D Sound System Im "Ok" If I Have To Use Multiple APIs To Do This But Please Help Me!

  • What are my tool options to prototype a 2D multiplayer game?

    - by Asher Einhorn
    I'm looking for the best tool to allow me to quickly put together a 2D game that relies largely on networking. It's extremely likely that this game will require a server side program to constantly run. I have little experience with these things and since it's a prototype i'd like the easiest options for achieving this. I am looking to make this game for the web and mobile devices, although at present I only have access to ios hardware, (no android etc). I just want to get the bare bones of this set up so I can test it from the earliest opportunity to see if it's fun.

  • Hashing 3D position into 2D position

    - by notabene
    I am doing volumetric raycasting and curently working on depth jitter. I have 3D position on ray and want to sample 2D noise texture to jitter the depth. Function for converting (or hashing) 3D position to 2D have to produce absolutely different numbers for a little changes (especialy because i am sampling in texture space so sample values differs very very little) and have to be "shader-wise" - so forget about branches, cycles etc. I'm looking forward for yours nice and fast solutions.

  • How can I ease the work of getting pixel coordinates from a spritesheet?

    - by ThePlan
    When it comes to spritesheets they're usually easier to use, and they're very efficient memory-wise, but the problem that I'm always having is getting the actual position of a sprite from a sheet. Usually, I have to throw in some aproximated values and modify them several times until I get it right. My question: is there a tool which can basically show you the coordinates of the mouse relative to the image you have opened? Or is there a simpler method of getting the exact rectangle that the sprite is contained in?

  • PhysX Capsule Character Controller floating above ground

    - by Jannie
    I am using PhysX Version 3.0.2 in the simulation package I'm working on, and I've encountered some bizarre behavior with the capsule character controller. When I set the controller's height and radius to the appropriate values (r = 0.25, h = 1.86)it behaves correctly (moving along the ground, colliding with other objects, and so on) except that the capsule itself is floating above the ground. The actor will then bump his head when trying to get through a door, since the capsule is the correct height but also floating above the ground. This image should illustrate what I'm going on about: One can clearly see that the rest of the scene has their collision bodies wrapped correctly, it's just the capsule that's going wrong! The stop-gap I've implemented is creating a smaller capsule and giving it an offset, but I need to implement ray-picking for the controller next so the capsule has to surround the character model properly. Here's my character creation code (with height = 1.86f and radius = 0.25f): NxController* D3DPhysXManager::CreateCharacterController( std::string l_stdsControllerName, float l_fHeight, float l_fRadius, D3DXVECTOR3 l_v3Position ) { NxCapsuleControllerDesc l_CapsuleControllerDescription; l_CapsuleControllerDescription.height = l_fHeight; l_CapsuleControllerDescription.radius = l_fRadius; l_CapsuleControllerDescription.position.set( l_v3Position.x, l_v3Position.y, l_v3Position.z ); l_CapsuleControllerDescription.callback = &this->m_ControllerHitReport; NxController* l_pController = this->m_pControllerManager->createController( this->m_pScene, l_CapsuleControllerDescription ); this->m_pControllerMap.insert( l_ControllerValuePair( l_stdsControllerName, l_pController ) ); return l_pController; } Any help at all would be appreciated, I just can't figure this one out! P.S. I've found a couple of (rather old) threads describing the same issue, but it seems they couldn't find a solution either. Here are the links: http://forum-archive.developer.nvidia.com/index.php?showtopic=6409 http://forum-archive.developer.nvidia.com/index.php?showtopic=3272 http://www.ogre3d.org/addonforums/viewtopic.php?f=8&t=23003

  • Scan-Line Z-Buffering Dilemma

    - by Belgin
    I have a set of vertices in 3D space, and for each I retain the following information: Its 3D coordinates (x, y, z). A list of pointers to some of the other vertices with which it's connected by edges. Right now, I'm doing perspective projection with the projecting plane being XY and the eye placed somewhere at (0, 0, d), with d < 0. By doing Z-Buffering, I need to find the depth of the point of a polygon (they're all planar) which corresponds to a certain pixel on the screen so I can hide the surfaces that are not visible. My questions are the following: How do I determine to which polygon does a pixel belong to so I could use the formula of the plane which contains the polygon to find the Z-coordinate? Are my data structures correct? Do I need to store something else entirely in order for this to work? I'm just projecting the vertices onto the projection plane and joining them with lines based on the pointer lists.

  • Image loaded from TGA texture isn't displayed correctly

    I have a TGA texture containing this image: The texture is 256x256. So I'm trying to load it and map it to a cube: #import <OpenGL/OpenGL.h> #import <GLUT/GLUT.h> #import <stdlib.h> #import <stdio.h> #import <assert.h> GLuint width=640, height=480; GLuint texture; const char* const filename= "/Users/ramy/Documents/C/OpenGL/Test/Test/texture.tga"; void init() { // Initialization glEnable(GL_DEPTH_TEST); glViewport(-500, -500, 1000, 1000); glMatrixMode(GL_PROJECTION); glLoadIdentity(); gluPerspective(45, width/(float)height, 1, 1000); glMatrixMode(GL_MODELVIEW); glLoadIdentity(); gluLookAt(0, 0, -100, 0, 0, 0, 0, 1, 0); // Texture char bitmap[256][256][3]; FILE* fp=fopen(filename, "r"); assert(fp); assert(fread(bitmap, 3*sizeof(char), 256*256, fp) == 256*256); fclose(fp); glGenTextures(1, &texture); glBindTexture(GL_TEXTURE_2D, texture); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, 256, 256, 0, GL_RGB, GL_UNSIGNED_BYTE, bitmap); } void display() { glClearColor(0, 0, 0, 0); glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glEnable(GL_TEXTURE_2D); glBindTexture(GL_TEXTURE_2D, texture); glColor3ub(255, 255, 255); glBegin(GL_QUADS); glVertex3f(0, 0, 0); glTexCoord2f(0.0, 0.0); glVertex3f(40, 0, 0); glTexCoord2f(0.0, 1.0); glVertex3f(40, 40, 0); glTexCoord2f(1.0, 1.0); glVertex3f(0, 40, 0); glTexCoord2f(1.0, 0.0); glEnd(); glDisable(GL_TEXTURE_2D); glutSwapBuffers(); } int main(int argc, char** argv) { glutInit(&argc, argv); glutInitDisplayMode(GLUT_RGB | GLUT_DEPTH | GLUT_DOUBLE); glutInitWindowPosition(100, 100); glutInitWindowSize(width, height); glutCreateWindow(argv[0]); glutDisplayFunc(display); init(); glutMainLoop(); return 0; } But this is what I get when the window loads: So just half of the image is correctly displayed, and also with different colors.Then if I resize the window I get this: Magically the image seems to fix itself, even if the colors are wrong.Why?

  • Octrees and Vertex Buffer Objects

    - by sharethis
    As many others I want to code a game with a voxel based terrain. The data is represented by voxels which are rendered using triangles. I head of two different approaches and want to combine them. First, I could once divide the space in chunks of a fixed size like many games do. What I could do now is to generate a polygon shape for each chunk and store that in a vertex buffer object (vbo). Each time a voxel changes, the polygon and vbo of its chunk is recreated. Additionally it is easy to dynamically load and reload parts of the terrain. Another approach would be to use octrees and divide the space in eight cubes which are divided again and again. So I could efficiently render the terrain because I don't have to go deeper in a solid cube and can draw that as a single one (with a repeated texture). What I like to use for my game is an octree datastructure. But I can't imagine how to use vbos with that. How is that done, or is this impossible?

  • Detect Open Space in Farseer

    - by Tom G
    I'm working on a 2D platformer using XNA and Farseer. I would like the player's character to be able to grab and climb up ledges. Detecting a collision between the player and the side of a wall is simple enough with the OnCollision delegate, but I have to admit I'm a bit stumped on how to detect that there's enough clearance for the PC to mount the ledge. Essentially, I want to ensure there's an appropriately sized rectangle above and to the left or right of the PC (depending on their direction) and I'm not sure how I would check for such a space. Any suggestions on how to determine there is nothing in the simulated world within some bounding rectangle?

  • Recommended formats to store bitmaps in memory?

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

  • How does opengl-es 2 assemble primitives?

    - by stephelton
    Two things I'm quite confused about. 1) OpenGL ES 2.0 creates primitives before the vertex shader is invoked. Why, then, does it not automatically provide the vertex shader the position of the vertex? 2) OpenGL ES 2.0 supports glDrawElements(), but it does not support glEnableClientState() or GL_VERTEX_ARRAY, so how can this call possibly be used to construct primitives? NOTE: this is OpenGL ES 2.0, NOT normal OpenGL! Thanks!

  • 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 to create games with scrolling?

    - by Chandan Shetty SP
    In games like city story or we farm how do they implement scrolling? To do scrolling using UIScrollView the EAGLView size has to be bigger. In those games EAGLView size look like more than 1024*1024. But there is limitation in viewport size in iphone devices(in 3G iphone max is 1024). I played those games in 3G iphone they are working fine. Any idea how they implemented their scrolling mechanism?

  • Buffer System For Items

    - by Ohmages
    I am going to reference this image of what I want to accomplish in JavaScript. This is the Diablo buffer system. This question may be a bit advanced (or possibly not even allowed). But I was wondering how you might go about implementing this type of system in a JavaScript game. Currently to implement such a system in JavaScript escapes me, and I am turning to SO to get some suggestions, ideas, and hopefully some insight in how I could accomplish this without being to costly on the CPU. Some thoughts of mine for implementing such a system would be to: Create DIVS within a DIV that hold each position of the inventory Go through each item you own in a container and see which DIV it belongs to Make said item images the DIVs image This type of system might possibly work if ALL items were 1x1, but for this example its not going to work out. I am at a complete lost of ideas how to even accomplish this. Although, maybe rendering directly to the canvas and checking mouse cords could work, there would more than likely be A HUGE annoyance when checking if other items are overlapping each other (meaning you cant place the item down, and possibly switching item with the cursor item ). That said, what am I left with? Do I need to makeshift my own hack system with messy code, or is there some source out there (that I don't know about) that has replicated this type of system in their own game. I would be very grateful to get some replies on how you might go about doing this, and will accept answers that can logically explain how you might implement such a system (code is not required). P.S. Id like to use pure JavaScript, and nothing else (even though it might be "reinventing the wheel", I also like to learn).

  • How can I install Ubuntu (SO many problems)

    - by Dragos
    I have a question, my friend tried installing Ubuntu on my notebook (Asus g75v) and nothing tried, at one point he went past the installation screen and every he used the mouse the screen flickered and the driver crashed (I assume) and it would go back a step, I heard that there is way to install ubuntu without any graphics, maybe that will help me with the screen flickering (I have a gtx 670m), so we tried WUBI installer, I tried installing with that and it gave me a Wubildr.mbr missing error, so I gave that up after several times, although I do notice that I have an intel driver, and I keep downloading AMD versions, does that effect anything? I'm having trouble installing Ubuntu and I wish to be able to run it on my laptop, I want to learn this OS and I cannot even install it, I am a bit concerned, if anyone can back at me with any answer at all, please don't hesitate to post, just please don't post if you don't know what's going on, thanks for listening! ~cheers -Dragos

  • What is the best way to exploit multicores when making multithread games?

    - by Keeper
    Many people suggest to write a program, and then start optimizing it. But I think that when it's coming to multithreading with multicore, a little think ahead is required. I've read about using threads, and experienced it myself during some courses at the university (still a student). The big question is simple, but a bit abstract: What thread related steps in game design do I need to take, before implementation? Now trying to be more specific. Let's say, as an example, that I'm making a small board game (like Monopoly) that I want to be multithreaded. My goal Is that this multithreaded game will exploit the best of the multicore system, lets say 4-6 cores (like in i7 processors). My answer to this question at the moment is, one thread for each of these four basic components: GUI User Input / Output AI (computer rival) Other game related calculations (like shortest path from A to B, or level up status change) I'm not an expert (yet!), and I'm sure there are better answers out there. Any suggestion, answer, different approach will be helpful. Some thoughts: Maybe splitting the main database is a good way.. (or total disaster.. )

  • How to handle jumping up a slope in a runner game?

    - by you786
    In an 2D endless runner, what should happen when the player is running "too fast" up a slope and jumps? For example, in a "normal" case: .O. . __..O_____ . / . / O/ _/ If he is moving to the right slowly enough, he will jump upwards and land on the flat part of the surface. However, if he is moving too fast, the jump will have no effect as his forward motion will bring him back in contact with the slope before he can get high enough to pass over it. When the speed is sufficiently high, there will effectively be no jump. _________ / .O/ O/ _/ Are there any known ways to solve this issue? I know it's physically correct*, but are there techniques that other games use to overcome this in a reasonable manner? As a last resort I'll have to just remove all slopes that are too slanted. *If you constrain the player to never jumping backwards.

  • Box2D platformer movement. Should i mess with velocity?

    - by Romeo
    I have a platformer game in which I implemented the movement using a wheel attached to the hero. For jumping I use this: player.body.applyLinearImpulse(new Vec2(0, 30000000), player.body.getPosition()); The problem is that the xVelocity doesn't remain the same during the jump so it isn't looking natural. Is there any way to modify only the x velocity of the body so that before jumping I store it in a variable and after jumping I apply it to the body? I hope you understand what I am trying to say.

  • How do I detect if sprite should be going up or down?

    I use the following code to detect if a sprite should be going up or down: If (pos.Y + 100) >= Sprite.BottomY Then Going_up = True pos.Y = Sprite.BottomY - 130 End If If pos.Y <= Sprite.TopY Then Going_up = False pos.Y = Sprite.TopY - 1 Vel.Y = 3 End If Then my response code: If Going_up Then Vel.Y -= CSng(gameTime.ElapsedGameTime.TotalMilliseconds / 40) pos.Y -= Vel.Y Else Vel.Y += CSng(gameTime.ElapsedGameTime.TotalMilliseconds / 40) pos.Y += Vel.Y End If Sprite.velocity = Vel Sprite.position = pos But it's pretty terrible. It only works when the sprite starts at the top, and when I want to change the BottomY and TopY, it just starts glitching. What is a better to detect if the sprite should be going up or down?

  • Maya is lagging in a specific way...?

    - by Aerovistae
    My Maya installation worked perfectly. It is not my computer. Something caused it to stop working overnight, somehow. When I try to drag a vertex or something like that, it moves the vertex, but then I have to click like 3 times somewhere outside the mesh before the actual mesh will catch up and follow the vertex. Until I do that, it just stays as it was, with a floating vertex somewhere inside it or outside it. It makes modeling borderline impossible and completely infuriating. What ought to be happening is what we're all used to-- as I move the vertex, the mesh follows it actively, so I can see what it looks like at every given moment until I release the vertex in its new position. Other weird thing: this only applies to complex meshes, like a couple thousand faces. A simple cube works fine. What gives?? Anybody?

  • HTML5 - check if font has loaded

    - by espais
    At present I load my font for my game in with @font-face For instance: @font-face { font-family: 'Orbitron'; src: url('res/orbitron-medium.ttf'); } and then reference it throughout my JS implementation as such: ctx.font = "12pt Orbitron"; where ctx is my 2d context from the canvas. However, I notice a certain lag time while the font is downloaded to the user. Is there a way I can use a default font until it is loaded in?
