The most advanced games I've made are a 8-ball pool game made with the physics engine Box2dFlashAS3 and a platform game with levels.

When I did platform games, I've always wished to know how to make an engine, so that I could re-use it. When I see games that have slopes, curved slopes, perfect gravity and real-life physics, I've always wished I knew how to code the engine.

Please suggest techniques and articles for whatever relevant knowledge-base is necessary.

Game Design Dilemma

as seen on Geeks with Blogs - Search for 'Geeks with Blogs'
I'm working on a 2d tilemapped RPG. I've actually made quite a fair amount of progress, but I'm at a point where I need to make a UI decision. I have the overland world completely mapped out, and I have several towns and special areas. I'm on the fence about how to integrate the two. Scenario 1: I… >>> More

So yesterday I didn't cut any code for my game but I was able to do a tiny bit of research on the XNA Game Development Technology and the communities out there and do you know what? I feel I'm a bit closer to my goal. The bad news is today I didn't cut code either. However, not all is lost because… >>> More

I have around 2.5 years of experience as a web developer cum designer working mainly on the LAMP platform. Now, I want to try out game development (of the likes of First Person Shooter games like Call of Duty (COD)). It is one of my dreams to some day succeed in making a profitable, popular, commercial… >>> More

I want to make video games, but I hate coding

I know this sounds eally crazy. However, I just want to ask. Now, I am studying C++ code in my school (My major is computer programming). Honestly, my grade is not so good, and assignments are really hard. Sometimes, I feel sad that I will spend 8~10 hours per day for coding (which is stressful)… >>> More

Implementing a wrapping wire (like the Worms Ninja Rope) in a 2D physics engine

I've been trying out some rope-physics recently, and I've found that the "standard" solution - making a rope from a series of objects strung together with springs or joints - is unsatisfying. Especially when rope swinging is relevant to gameplay. I don't really care about a rope's ability to wrap… >>> More
Converting 2D Physics to 3D.

I'm new to game physics and I am trying to adapt a simple 2D ball simulation for a 3D simulation with the Java3D library. I have this problem: Two things: 1) I noted down the values generated by the engine: X/Y are too high and minX/minY/maxY/maxX values are causing trouble. Sometimes the balls… >>> More

The game I'm working on involves shapes that might be composed of multiple materials in a variety of ways. Let's just take for example a wooden rod with and sizable tip of iron or say a block composed of a couple triangles of stone and aluminum and small nugget of gold.
