Teaching behavior to GameObjects

You have Unity because you want to make a game or something interactive, such as an AR or VR experience. You've filled your game with dumb GameObjects. What you have to do now is be their teacher. You have to teach them everything that they need to know to live in this world of make–believe. This is the part where you have to write down instructions so that your GameObjects can be smarter.

Here's a quote from the Unity Manual:

"The behavior of GameObjects is controlled by the Components that are attached to them... Unity allows you to create your own Components using scripts."

Notice the word behavior. It reminds me of a parent teaching a child proper behavior. This is exactly what we are going to do when we write scripts for our GameObjects: we'll teach them the behaviors we want them to have. The best part is that Unity has provided a long list of all the behaviors that we can give to our GameObjects. This list of behaviors is documented in the Scripting Reference.

This means that we can pick and choose anything that we want a GameObject to do from this list of behaviors. Unity has done all the hard work of programming all of these behaviors for you. All we need to do is use some code to tie into these behaviors. Did you catch that? Unity has already created the behaviors; all that we have to do is supply a bit of C# code to apply these behaviors to our GameObjects. Now, how difficult can it really be since Unity has already done most of the programming?
