One of the most visited articles on our site – How to Use Perlin Noise in Your Games – also caused the most problems. The pseudo-code contained an alarming number of bugs (one of the nastier ones is depicted above), which made it difficult to implement. Readers pointed out these in the comments, and so [...]
This tutorial provides some algorithms useful for working with Bézier curves: determining the length of a piece of curve; interpolating a set of points with a Bézier path; and reducing a large point set to a smooth Bézier curve.
A distillation of the five puzzle game design interviews, taking together advice from Rob Jagnow, Guy Lima, Ted Lauterbach, Teddy Lee, Dave Hall and Teddy Lee.
Dev.Mag talks to Guy Lima, one of the founders of Ragtime Games, on how he and his team designed the puzzles for Continuity, the sliding-tile platform puzzler.
This article gives some background information on puzzle games, and sets the stage for a set of interviews on puzzle game design.
A Bézier curve is a type of curve that is easy to use, and can describe many shapes. This guide gives instructions for implementing algorithms for using Bézier curves in your games.
In this second part of analyzing Desktop Dungeons, we look at how choices are given meaning not only through their complexity, but also through the role they play in structuring an experience.
This is the first part of an in-depth look at the design of Desktop Dungeons, the South African game that won the Excellence for Design Award at the IGF. In this part, we look at the player actions, choices, and tension.
Quadtrees are 2D data structures, useful for efficient representation of 2D data (such as images), and lookup in a 2D space. This is a simple implementation tutorial.
This article shows how to implement a simple graphical logging system to find errors in physics, AI and animation faster.
Text files can be messy when logging events from games. In this article, Herman Tulleken shows you how to use HTML, CSS and JavaScript to build visually informative logs that make debugging easier.
I have a weak spot for cool game development tools. Not the IDE, or art or sound tools – I mean the level editors, AI construction tools – those that developers develop specifically for their games. Those that you know could help you multiply your content, and craft your game just a little bit better.
This tutorial covers basic algorithms with vectors.
