Creating a variable and seeing how it works

Now using a different method, we are going to develop a script that shows us the result on the Unity console. Once again, don't be concerned about the details of how to write this; we are going to explain everything in more detail in future chapters. Just make sure that your script is the same as the script shown in the next screenshot:

1. In the Unity Project panel, double-click variableScript. The MonoDevelop window should open automatically on variableScript.cs.
2. In MonoDevelop, erase what we have done before and write the lines 7, 12, and 14, as shown in the following screenshot:

1. Save the file.

The best way to save your script is by using a shortcut. If you are using a Mac, use command + S, and on Windows use Ctrl + S. We will be saving a new version of the script every time some changes are made to it, so it is a good idea to use a shortcut instead of saving through the File menu.

We have added a few lines to our script. Before we check whether it works or what it actually does, let's go through line 7:

public int myNumber = 9; 

In simple words, this line declares a new number type variable named myNumber
and assigns a value of 9 to it. We don't want to worry about theory too much now and want to write more code, right? Agreed, but we do need to remember a few things first.
