Introduction
Sometimes 2D gameplay calls and you can't resist its alluring charm! Unity can handle it. This tutorial shows the steps you need to create a basic 2Dstyle platform game.
Why 2D is the Bee's KneesIt is no secret that Unity can help you create great threedimensional games with ease. Its raw power and flexibility allows even beginners to create impressive games with out much difficulty. Unity is undoubtedly a great 3D game engine so why on earth would you want to create a 2D game with it? For certain game types, that extra "D" in 3D can be a hindrance. Some games simply work better with twodimensional gameplay mechanics. Think of those simple and fun 2D sidescrolling games you have played in the past, or maybe you have a simple puz zle game idea that would work best constrained to two dimensions the list keeps going but the bottom line is many games can benefit by the use of only two dimen sions. Twodimensional games are also commonly easier for the casual gamer to understand, which is something to consider if you're a small game developer (see the article "Cas ual Games as a Business"). Luckily, Unity is extremely flexible and can easily handle 2D gameplay! Its world class Ageia PhysX is highly adaptable and can be constrained in many ways including two dimensions. In this tutorial we define a 2D Game as a game where graphics are still in 3D, but restricted motion causes the physics and gameplay only to occur in a single 2D plane. This lets us use 3D models for our content and makes life easier for artists and devel opers alike. One could say that we're using the best of both worlds: the ease of 2D
gameplay and the beauty of 3D graphics with the added attraction that existing de velopers already have a good 3D asset production pipeline in place. This tutorial will guide you in building a 2D platform game. We have designed this tutorial with beginner / intermediatelevel users in mind; we only ask that you have a baseline knowledge of Unity. We have also included some advanced concepts that may be of interest to more seasoned users. We begin by getting you into the 2D mindset. Then we will walk you through building a 2D world in which your character will move around. After adding a few cool ob stacles and scenery, we'll lastly add a rocket ship for the player to fly. We hope you enjoy this tutorial as much as we had fun creating it!
