Bumping Into Things

Abstract

Welcome to a fun chapter! In these pages you’ll build an interactive playground of clever little game design techniques that you can expand upon to build completely interactive two-dimensional environments, better known as action and adventure games! A whole grab bag of things from collision detection, building walls, and picking up and dropping objects—they’re all here. With a little imagination, you’ll be able to use these very simple techniques to produce different kinds of games. Hey, congratulate yourself: you’ve come a long way since page 1! All your hard work is about to pay off.
