A long held tradition in programming is to write a simple program called "Hello, World!" as your very first program. This program normally prints the words "Hello, World!" on the screen, and is used as a starting point to understanding the basics of a new programming language or development environment. This is a tradition that dates back to at least 1972, but potentially even further back to 1967.
Here, we will create a "Hello, World!+". We will use it to further familiarize you with Unity, beyond the basic layout of the preceding chapter. In an effort to avoid repeating steps, we will build onto this project throughout the rest of the book.
