Collision Detection
COLLISION DETECTION Jeff Thompson The collision of objects underlies most game experiences and user-interfaces. Baseball bats collide with balls, zombies bump into walls, and Mario lands on platforms and stomps turtles. Even something as simple as clicking a button (a rectangle) with your mouse (a point) is a collision. This book explains the algorithms behind those collisions using basic shapes l
JavaScriptで大量のオブジェクトの当たり判定を効率的にとる - Subterranean Flower Blog
ゲームなどのコンテンツにおいて、「当たり判定」から逃れることはできません。オブジェクトとオブジェクトが衝突したかどうかという判定は、インタラクティブコンテンツにおいて最も重要な部分になるからです。 当たり判定の実装自体は難しくありません。ですが、素朴な実装ですと、対象となるオブジェクトが大量である場合に、十分なパフォーマンスが出ません。これはオブジェクトの多い、現代的なゲームでしたり、弾幕シューティングなどを作るときに大きな障害となります。 この記事では、大量のオブジェクトの当たり判定を処理する、効率的な方法について紹介します。 まずは素朴に実装してみる 当たり判定の処理を語るには、ある程度ゲームの骨組みのようなものが必要になってきます。もちろんクラスなどを使わないベタ書きでもよいのですが、大変読みにくくなってしまいます。ですので、今回は、まず簡易的なゲームエンジンのようなものを作って、そ

Procedural City Generation - Projects
Procedural City Generation [code]Click and hold to navigate. Click on two locations to find a path. Since seeing the city generation from the shelved Introversion Software game “Subversion” in action, I’ve wanted to to try writing a basic procedural city generator myself. The developers followed a method described in Parish and Müller’s paper: Procedural Modelling of Cities (2001). The paper is we
Rooms and Mazes: A Procedural Dungeon Generator – journal.stuffwithstuff.com
Several months ago I promised a follow-up to my previous blog post about turn-based game loops in my roguelike. Then I got completely sidetracked by self-publishing my book, Game Programming Patterns, and forgot all about it. I totally left you hanging. Well, I finally got some time to think about my roguelike again and today, I’m here to… keep you hanging. Alas, you are at the mercy of my wanderi

Introduction to Octrees
What exactly is an Octree? If you're completely unfamiliar with them, I recommend reading the Wikipedia article (read time: ~5 minutes). This is a sufficient description of what it is but is barely enough to give any ideas on what it's used for and how to actually implement one. In this article, I will do my best to take you through the steps necessary to create an octree data structure through co
Generate Random Cave Levels Using Cellular Automata | Envato Tuts+
Procedural content generators are bits of code written into your game that can create new pieces of game content at any time - even when the game is running! Game developers have tried to procedurally generate everything from 3D worlds to musical soundtracks. Adding some generation to your game is a great way to plug in extra value: players love it because they get new, unpredictable and exciting
The Cellular Automaton Method for Cave Generation
This article was ported from my old Wordpress blog here, If you see any issues with the rendering or layout, please send me an email. Dear reader, this post has an interactive simulation! We encourage you to play with it as you read the article below. In our series of posts on cellular automata, we explored Conway’s classic Game of Life and discovered some interesting patterns therein. And then in
