Chapter 30: Prototype 3: Space Shmup
The SHMUP (or shoot ’em up) game genre includes such classic games as Galaga and Galaxian from the 1980s and the modern masterpiece Ikaruga.
In this chapter, you create a SHMUP using several programming techniques that will serve you well throughout your programming and prototyping careers, including class inheritance, enums, static fields and methods, and the singleton pattern. Though you’ve seen many of these techniques before, they will be used more extensively in this prototype.
Unity 2018.2.2 – Camera.main Bug
- In Unity 2018.2.2, sometimes when creating a Camera, the tag of the Camera is set to “Untagged” instead of “MainCamera”. As a result, any references to Camera.main will cause Null Reference Exceptions.
- To remedy this, all you need to do is set the tag of the Main Camera to MainCamera.
