💬 As you're starting out you might learn to set things as public in order to expose them in the Editor.
In this video I tell you why you should NOT do that!
The reason is to write good clean code that minimizes code complexity. The less accessible your variables are the better.
If you have an error with a variable that is set to public, you don't know where the error comes from, it might be in that class or any other class in your entire code base since every class can modify that field.
However when you set it to private you make sure that any issues that occur have to be happening from within that class, that really helps on keeping a smaller mental model of what your code is doing.
And if you want to expose a variable in the editor, simply use the attribute [SerializeField]
That way you keep your code nice and clean but still keep it editable in the Editor.
