Material System
Game Development
I'm designing Material/Shader System (target API DX10+ and may be OpenGL3+, now only DX10). I know, there was a lot of topics about this, but i can't find what i need.I don't want to do some kind of compilation/parsing scripts in real-time.So there some artist-created material, written at some analog of CG.After it compiled to hlsl code and after to final shader.Also there are some hard-coded Cons

Problem converting FBX file into XNB
Game Development
I create a Monogame Content Project to convert assets into XNB. For FBX file without texture there is no problem: the file is correctly converted and when I load XNB into my project everything is ok. The problem occours when i have associated to fbx file a texture map: in this case both FBX and PNG files are converted to XNB but when i try to load these XNB files into my project the following prob

Rotate around the centre of the screen
Game Development
I want my camera to rotate around the centre of screen and I'm not sure how to achieve that. I have a rotation in the camera but I'm not sure what its rotating around. (I think it might be rotating around the position.X of camera, not sure) If you look at these two images: http://imgur.com/E9qoAM7,5qzyhGD#0 http://imgur.com/E9qoAM7,5qzyhGD#1The first one shows how the camera is normally, a

How can I implement a scanline effect?
Game Development
I am working on an old-school platformer in libgdx and I want it to have a "scanline" effect, like this:My first attempt was to make a little texture and draw it on a full-screen quad. I used two different orthographic camera modes (one for the main tilemap of the game, and a second to render the scanline texture). Sometime the texture is stuck on the tilemap and sometime it is too large, and cove

RPG systems for video games [on hold]
Game Development
I have been working on a story from last few years and now that I think that it's polished enough (and I have learnt a decent amount of coding), it's time to actually create it. Problem is- I don't want to use a existing pen-and-paper system because they are created to be mathematically simple and easy to operate. A computer based RPG has no need to be mathematically simple. I want to make a reali

character movement data passing on server
Game Development
I am trying to build my first online game using unity with photon, the data transfer between server and clients is implemented but I am facing a great problem; How/What should be transferred to synchronise the movement data? My game has a lobby and may have as many as 20 people online at the same time if I pass the position of every players to server and then server to clients, I believe the serve

Skeletal animation with Assimp and glm
Game Development
I'm trying to implement skeletal animation using assimp and glm. Everything seems to work, except for rotations.This is the code I use when packing assimp data into my own engine's format. I THINK it should be correct, but since I've already run into problems with matrices (assimp uses row major, glm - column major), I'd rather post this, too:for(uint32_t l = 0; l < tempChannel.numRotationKeys;

Why are some of my normals facing away from the camera?
Game Development
I'm trying to use WebGL to render some simple models, and I'm running into issues where pixels near the edge of my model are passing normals to my fragment shader that point away from the camera. This is of course messing with my attempts to use physically-based shading, because BRDFs are only defined in the hemisphere around the normal vector. These normals aren't just slightly pointing away from

DirectX error with older XP systems
Game Development
I am a blind programmer, working on an audio game for the blind. I am using SlimDX, and it has been tested on dozens of systems from XP to Win 8.1. My code works on most systems just fine, but I am getting the following error at runtime on a handful of older XP systems: vupgraderacer.wav SlimDX.DirectSound.DirectSoundException: DSERR_INVALIDCALL: This call is not valid for the current state

How can I control an object with tilt gestures?
Game Development
I want an object (for example a ball) to move right when I tilt my Windows Phone device to the right. The same with the directions left, up and down. If the Windows Phone device isn't getting tilt in a direction, the object should rest in place.How can I do that?
