• 2D Ragdoll - should it collide with itself?

  - by Axarydax

  Hi, I'm working on a ragdoll fighting game as a hobby project, but I have one dilemma. I am not sure if my ragdoll should collide with itself or not, i.e. if ragdoll's body parts should collide. 2D world is somewhat different than 3D, because there are several layers of stuff implied (for example in Super Mario you jump through a platform above you while going up). The setup I'm currently most satisfied with is when only the parts which are joined by a joint don't collide, so head doesn't collide with neck, neck with chest, chest with upper arm etc, but the head can collide with chest, arms, legs. I've tried every different way, but I'm not content with either. Which way would recommend me to go?

• Premultiplying matrices with Perspective destroys them

  - by Shadows In Rain

  If I apply world_to_camera, perspective and camera_to_screen to my mesh, everything is okay. But if I premultiply given matrices (i.e. transform = world_to_camera * perpective * camera_to_screen) before applying, then it seems like only perspective has effect. If it is important... My 3d framework was written from scratch (test project for job interview). But it works flawlessly, or at least I think so. So, question. This is expected behaviour, or my implementation is wrong?

• 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.

• How does a collison engine work?

  - by JXPheonix

  Original question: Click me How exactly does a collision engine work? This is an extremely broad question. What code keeps things bouncing against each other, what code makes the player walk into a wall instead of walk through the wall? How does the code constantly refresh the players position and objects position to keep gravity and collision working as it should? If you don't know what a collision engine is, basically it's generally used in platformer games to make the player acutally hit walls and the like. There's the 2d type and the 3d type, but they all accomplish the same thing: collision. So, what keeps a collision engine ticking?

• unit testing on ARM

  - by NomadAlien

  We are developing application level code that runs on an ARM processor. The BSP (low level code) is being delivered by a 3d party so our code sits just on top of this abstraction layer (code is written in c++). To do unit testing, I assume we will have to mock/stub out the BSP library(essentially abstracting out the HW), but what I'm not sure of is if I write/run the unit test on my pc, do I compile it with for example GCC? Normally we use Realview compiler to compile our code for the ARM. Can I assume that if I compile and run the code with x86 compiler and the unit tests pass that it will also pass when compiled with RealView compiler? I'm not sure how much difference the compiler makes and if you can trust that if the x86 compiled code pass the unit tests that you can also be confident that the Realview compiled code is ok.

• Are there jobs which are oriented towards optimisation programming or assembly

  - by jokoon

  3D engine programmers have to care a little about execution speed, but what about the programmers at ATI and nVidia ? How much do they need to optimize their driver applications ? Are there jobs out there who only purpose is execution speed and optimisation, or jobs for people to program only in assembly ? Please, no flame war about "premature optimisation is the root of all evil", I just want to know if such jobs exists, maybe in security ? In kernel programming ? Where ? Not at all ?

• Move Camera Freely Around Object While Looking at It

  - by Alex_Hyzer_Kenoyer

  I've got a 3D model loaded (a planet) and I have a camera that I want to allow the user to move freely around it. I have no problem getting the camera to orbit the planet around either the x or y axis. My problem is when I try to move the camera on a different axis I have no idea how to go about doing it. I am using OpenGL on Android with the libGDX library. I want the camera to orbit the planet in the direction that the user swipes their finger on the screen.

• System hangs at glReadPixel call with GL_TEXTURE_2D_ARRAY for texturing

  - by Roshan

  I am calling glReadPixel after glDrawArray call. I am rendering a geometry with 3D texture on it as a target GL_TEXTURE_2D_ARRAY. My systems hangs at glreadpixel call. When i use target as GL_TEXTURE_3D the issue does not occurs and it correctly reads the framebuffer contents. glReadPixels(0, 0, GetViewportWidth(), GetViewportHeight(), GL_RGBA, GL_UNSIGNED_BYTE, (GLvoid *)rendered_pixels); I am using SNORM textures with GL_byte data in glTeximage3D call and I am not calling glPixelStorei, is it because of this? What should be the parameter for pixelstore call?

• Animations not accepted in animator

  - by Lautaro

  In the official Unity Animator State Machine tutorial video animation clips are dragged out from the assets folder into the animator and dropped. I have a 3D model that i bought online to experiment with that comes with animations. I added a custom made animation as well. These all work well in my demo project. But when i add a animator to the assets and try to drag and drop animations onto it it doesnt work. I get a forbidden-sign as a mouse pointer. I try to add animations through the inspector but that does not work either. The tutorials makes it seem so easy and does not talk anything about what animations can be used. What am i doing wrong?

• Detailed Modern Opengl Tutorial?

  - by Kogesho

  I am asking for a specific modern opengl tutorial. I need a tutorial that does not skip to explain any lines of code. It should also include different independent objects moving/rotating (most tutorials use only one object), as well as imported 3d objects and collision detection for them. It should also avoid stuff that won't be used. Arcysnthesis for example gives a new concept, and after teaching it, in the next tutorial, it explains how bad it is for performance and introduces another method. Do you know any?

• Ubuntu - Psychonauts - Camera involentarily listing to the right

  - by James

  I've recently purchased the Humble Bundle V and have been having an absolute riot with the games given. The one problem I'm running into though, is that whenever I launch Psychonauts and run a game, the Camera lists to the right slowly and I can't get it to stop. Strangely enough when I zoom in (with z), it lists to the left. I was wondering if anyone else had this problem and if there was a solution. Maybe it's even the mouse configs I currently have on the laptop that interacts strangely with 3D environments.

• How do you start modding a game without an editor?

  - by Protector one

  I often come across very impressive mods for PC games that don't have an official editor, other development tools or its source code publicly available. (Take this amazing Multiplayer mod for Just Cause 2, for example.) How do you go about creating mods for such games? I'm not talking about replacing the odd texture or 3D model—that sort of thing seems fairly easy given tools to pry them out of game files and put them back in—but more along the lines of adding game behavior. (Tweaking settings files also doesn't count.) Note that I'm not asking "how to create a mod", I just want to know where to start or where to go to learn.

• Do I need the 'w' component in my Vector class?

  - by bobobobo

  Assume you're writing matrix code that handles rotation, translation etc for 3d space. Now the transformation matrices have to be 4x4 to fit the translation component in. However, you don't actually need to store a w component in the vector do you? Even in perspective division, you can simply compute and store w outside of the vector, and perspective divide before returning from the method. For example: // post multiply vec2=matrix*vector Vector operator*( const Matrix & a, const Vector& v ) { Vector r ; // do matrix mult r.x = a._11*v.x + a._12*v.y ... real w = a._41*v.x + a._42*v.y ... // perspective divide r /= w ; return r ; } Is there a point in storing w in the Vector class?

• System locks up at login after latest update on 12.04

  - by RCD

  For starters, I am a noob when it comes to Ubuntu and Linux...but I am hopeful that I have the "light" and the error of my past MS ways :) ..... After a recent update last week from 12.04 to 12.04.1 my system now locks up at the login screen. Before the update the system would run but must admit it ran EXTREMELY slow. I have installed 12.04 on a Dell P4 2.4 Ghz, 2 GB DDR Ram, 80 GB IDE HD and an integrated Intel 3D Extreme Graphics. Any ideas on why now the system locking up at login screen? Appreciate any ideas and/or tips Thanks

• Wall avoidance steering

  - by Vodemki

  I making a small steering simulator using the reynolds boid algorythm. Now I want to add a wall avoidance feature. My walls are in 3D and defined using two points like that: ---------. P2 | | P1 .--------- My agents have a velocity, a position, etc... Could you tell me how to make avoidance with my agents ? Vector2D ReynoldsSteeringModel::repulsionFromWalls() { Vector2D force; vector<Wall *> wallsList = walls(); Point2D pos = self()->position(); Vector2D velocity = self()->velocity(); for (unsigned i=0; i<wallsList.size(); i++) { //TODO } return force; } Then I use all the forces returned by my boid functions and I apply it to my agent. I just need to know how to do that with my walls ? Thanks for your help.

• Audio libraries for PC indie games [closed]

  - by bluescrn

  Possible Duplicate: Cross-Platform Audio API Suggestions What options are out there these days for audio playback/mixing in C++? Primarily for Windows, but portability (particularly to Mac and iOS) would be desirable. For a small indie game, potentially commercial, though - so I'm looking for something free/low-cost. My requirements are fairly basic - I don't need 3D sound, or many-channels - simple stereo is fine. Just need to be able to mix sound effects and a music stream, maybe decoding one or more compressed audio formats (.ogg/.mp3 etc), with all the basic controls over looping, pitch, volume, etc. Is OpenAL more-or-less the standard choice, or are there other good options out there?

• How to achieve 'forward' movement (into the screen) using Cocos2D?

  - by lemikegao

  I'm interested in creating a 2.5D first-person shooter (like Doom) and I currently don't understand how to implement the player moving forward. The player will also be able to browse around the world (left, right, up, down) via gyroscope control. I plan to only use 2D sprites and no 3D models. My first attempt was to increase the scale of layers to make it appear as if the player was moving toward the objects but I'm not sure how to make it seem as if the player is passing around the objects (instead of running into them). If there are extensions that I should take a look at (like Cocos3D), please let me know. Thanks for the help! Note: I've only created 2D games so was hoping to get guided into the right direction

• Is it only possible to display 64k vertices on the monitor with 16bit?

  - by Aufziehvogel

  I did the first 3D tutorial over at riemers.net and stumbled upon that my graphic card only supports Shader 2.0 (Reach profile in XNA) which means I can only use Int16 to store the indices (triangle to vertex). This means that I can only store 2^16 = 65536 vertices. Also I read on the internet that you should prefer 16-bit over 32-bit because not all hardware (like mine) does support 32-bit. Yet, I am wondering: Do really all game scenes get along with only so little vertices? I though already faces of people used a lot of polygons (which are made up of vertices?). It’s not relevant for me yet, but I am interested: Do game scenes use only 65536 vertices? Do you use some trade-off to display more (e.g. 64k in GPU buffer rest on RAM) Is there some method to get more into the GPU buffer? I already read on some other posts that there seems to be a limit of 64k per mesh too, so maybe you can compact stuff to meshes?

• How much time it will take to learn 3ds Max

  - by Mirror51

  I am not a 3d developer but i want to lean 3ds max just for simple house building with 2-3 rooms. Actually i don't want to develop from scratch . What i really want to do is get the existing models of homes , rooms , hotels from the internet and add my name there or my photo there , just for fun . SO i want to know that how much time do u think it will take me to that sort of stuff. Its not my career but just hobby . If its going to take longer time , then i don't want to waste but i can get going in one week or so that will go good but i want to ask from experience developers thanks

• Missing launcher, top panel without icons, an ATI driver problem?

  - by jlotero

  After upgrading to Ubuntu 11.10, the following problems occurs when accesing in ubuntu mode (3D): the launcher is missing, top panel without icons on the right side, and I can only restart with Terminal (Alt-T and then sudo reboot). No problems in 2D. It occurs on my PC with AMD Athlon (tm) II X4 640 Processor, Radeon HD5670 and both with the 32-bit and 64 bits versions of Ubuntu. Both versions work well on an older PC with AMD Athlon 64 x2 Dual Core 4200 + processor, and an Nvidia integrated graphics card (C61 GeForce 6150SE nForce 430). Could it be a problem with the ATI driver?

• Game Asset Storage: Archive vs Individual files

  - by David Colson

  As I am in the process of creating a 3D c++ game and I was wondering what would be more beneficial when dealing with game assets with regards to storage. I have seen some games have a single asset file compressed with everything in it and other with lots of little compressed files. If I had lots of individual files I would not need to load a large file at once and use up memory but the code would have to go about file seeking when the level loads to find all the correct files needed. There is no file seeking needed when dealing with one large file, but again, what about all the assets not currently needed that would get loaded with the one file? I could also have an asset file for each level, but then how do I deal with shared assets This has been bothering me for a while so tell me what other advantages and disadvantages are there to either way of doing things.

• Alternatives to voxel-based terrain

  - by Neomex

  Are there any alternatives to voxel based terrains? Such terrain should be fully destructable, allow for arches, overhangs, preserve sharp features where needed and keep consistent topology. Maybe you can explain the problem that makes you ask this question? Voxel based terrain is basically just using a 3D grid of data to store data. There are lots of ways to render that data, but it doesn't get much simpler for storing it. – Byte56 Current isosurface extraction methods aren't most effective/bug-free. Cubical Marching Squares seem to solve most of the issues, however it is a relatively new method and there aren't too many resources about it. (I've found single university paper) Even if we stick to CMS, when we want to add multi-material support, we can either divide surface into multiple meshes, or pass a texture array or texture atlas to shaders, then we are limited to set amount of textures and additionally increase memory-usage alot.

• What file formats and conventions should I support to make my game engine artist-friendly?

  - by Avi

  I'm writing a game engine, and I want to know what I should do to make it more artist-friendly. I don't want to be too limiting in terms of what file formats I support, etc. Some specific questions: Are there specific formats artists like to model in? Does it not matter because the 3D modeler abstracts the data storage away? Is it okay if I don't support per-vertex coloration in my game engine? If I have to store a diffuse, specular, ambient, and emissive color value for each vertex, it doubles the size of vertices in the buffer. Is it reasonable to ask artists to do all these things in textures / maps? Any other tips you have about making it so that artists have to adapt their style to my specific engine as little as possible would be nice.

• What should I do if my text exceeds my text render target boundaries?

  - by user1423893

  I have a method for drawing strings in 3D that does the following: Set a render target Draw each character as a quadrangle using a orthographic projection to the render target Unset the render target Draw the render target texture using a perspective projection and a world transform My problem is how to deal with strings whose characters length exceeds that of the render target dimensions? For example if I have string "This is a reallllllllllly long string" and the render target can't accommodate it, it will only capture "This is a realllll". The render target (and its size) could be set each frame but wouldn't that be far too costly?
