Missing Vector2, Vector 3 and whatelse

Long story short, I watched this tutorial (

) and wanted to give it a try, just to see what it's like. My problem is that I can't find the Vector2 struct, I don't have... The thing is that I haven't watched any tutorial yet (I know) because I couldn't find any that actually explained what I need to install nor whether the vectors are created, downloaded or any other option.

What am I missing? I am an absolute beginner, so, what should I read first?

 

You only need Unity and one of the compatible code editors to see autocompletion of code. Visual Studio is a very common choice because it's the easiest to get working. You either install it through the Unity installer, or you tell it to install for game development with the standalone installer.

 

I do have visual studio installed, also installed Unity through the Hub (with the correspondent SDK for Android), also configured Unity for Android, which lead to me think that I have dont everything correctly, but as you can see in the pic none Vector shows as well as most of the codes on the first half of the video. Help xD

 

What do I need to install? In what order? I think I'm missing something. What I want to do is to be able to create games for android (first simple games, then more elaborate), but my problem is that some codes just don't exist in the VS.

 

Switching to another engine then, please close this.
