Fix Your Timestep
Introduction Hi, I’m Glenn Fiedler and welcome to Game Physics. In the previous article we discussed how to integrate the equations of motion using a numerical integrator.

Minesweeper: Advanced Tactics (2005)
In this position, I know about a bunch of mines on all the remaining fronts, but I can't quite determine where they are. There are a few mines that might be in one of two positions (red or blue), a cluster of mines that might be in one of two arrangements (green), and a more complex situation in the top left which I…

Common Lisp and Music Composition
Once upon a time, there were many music composition software packages, mostly written in Common LISP.

A pair of dice which never roll 7 (2004)
Some friends of mine play the board game Settlers Of Catan . In this game, each player rolls two ordinary dice on their turn, and the number which comes up determines what resources people get for the turn. When a seven is rolled, something special happens: no resources are generated, and instead a robber moves on the…

A whole boss fight in 256 bytes
Endbot is a complete audio-visual demo that fits in exactly 256 bytes . It runs under DOS (via DosBox-X) and renders in real-time: a robot sprite with progressive bullet damage, a growing explosion, a scrolling checkerboard landscape, and a MIDI soundtrack - all from a single tiny .com file.

Doing Windows, Part 1: MS-DOS and Its Discontents
Has any successful piece of software ever deserved its success less than the benighted, unloved exercise in minimalism that was MS-DOS?

Make a Doom level, part 1: the basics
I love Doom. Or, well, I love Doom 2, which is the game we actually had when I was nostalgia years old. I love the aesthetic — pixely in a 3D(ish) environment, and consistent in a way that meshes together really well.
