XNA - About the relation between world space and the screen space

Edit: Just wanted to make the question I have more clear. I pretty much am having trouble seeing how something like Matrix.CreateTransformationZ works in the context of not only matrix multiplication but more importantly what this does to the screen space/world space so I can get a clearer picture. So maybe someone could alter the code o...

Reverse engineering a game user interface -programming techniques

Hello everyone, I have programmed some user interfaces throughout my career, however they have always been somewhat dull, amateurish, and ugly. I was just playing Starcraft 2 a few minutes ago and was wondering how is something like that implemented? They probably use OpenGL for the spaceship to do the 3-d but what do they use for the...

My problem is trying to make this actually work, with ellipses colliding. I will explain more if necessary. Thx ...

Treat multiple objects like one - WPF

Hi I am making a WPF soccer game using C#, and was wondering if it was possible to, say, put players in a class and when the ball hits them the same collision properties apply to all. And when you get the bounds for a bunch of objects, it gets the bounds for all in one sweep. Anyway, is it possible to treat multiple, identical but sepa...

Need an easy to use 3d game engine.

I'm looking for a VERY easy to use 3d game engine. I want to program only the logic of the game, and don't want to have to concern myself with graphics.

Why do game companies look for only C/C++?

Most of the requirements for a game programming job I've looked at required good C/C++ skills. I agree, most game engines are written in C/C++. But aren't the engines USED in a scripting languages? Don't the companies need scripting programmers to actually code the game from the game engine? Why haven't I ever seen a company that requir...

Pendulum with moving pivot

I'm making a game which you can see here, if you are on Windows or Linux: http://insertnamehere.org/birdsofprey/ If you click and hold your mouse on a bird, you can see I'm just swinging the bird back and forth in pendulum motion. I would like to, instead, implement a more realistic motion, where the movement of your mouse affects the s...

Techniques employed for artstyle of sharp 2D visuals/animation

This is more of an offbeat question I guess but I am curious as to what graphic designers do to make flat images like in Paper Mario, Limbo or Shank so sharp. The extent of my knowledge goes into an intermediate level of Maya and some sprite creation in photoshop but I never understood the process through which they create such visuals. ...

Any good tutorials for building composite patterns?

Hi I'm making a game of soccer in WPF with C#. A composite pattern sounds like a good idea to control multiple players properties, and such. This is nothing to do with event handlers. So if there are any good tutorials that anyone knows of - thanks. ...

Should I use multiple classes for game?

I'm considering making a text-based RPG-type program in PHP as both a holiday project and a chance to learn more about PHP and OOP. (Maybe not the best choice in language, I know, but I didn't want to have to learn another language from scratch at the same time as OOP.) Anyway, I'm just beginning the design process and thinking about 'm...

Does restricting the frames/s of a game engine (via vertical sync or common throttling), inflict latencies also on audio and input subsystems?

I was contemplating the fact that inflicting frame per second restrictions is not ideal in regards to latency and performance since a monitor still has a chance to show something sooner (assuming no vertical sync which is mainly for stability). However, it occurred to me that process might have ramifications on audio subsystems (or als...
