Quick 2D Workflow

In this chapter we’ll put together a simple 2D game in Unity using only the standard tools and editor features. This game is a space-invaders style clone featuring a player-controlled spaceship at the bottom of the screen (see Figure 3-1). In this game, the player can move horizontally, left and right, and must shoot invading aliens at the top of the window. The purpose of this exercise is not to show you how to make space-invader style games (though it will do that!) but to show you the more abstract principles and workflows for making “simple” 2D games quickly without having to code any additional features or editor plug-ins. This workflow shows that it’s entirely possible to make 2D games straight away in Unity ...
