//Public Mean I can access via other script.
//class that to tell that a class aka "block of data & function"
//Coins is actually the name of my .cs file and class.
//MonoBehaviour is to tell Unity that I use it's code :)
public class Coins : MonoBehaviour {

    //void is set to create class for "function" there.
    //Update() is name of the function that constantly run. (no need to call it.)
    void Update() {

        //Adding a function name that way would mean to Execute it Here Now.
        RotateTheCoin();
    }

    //Void as always create a function.
    //RotateTheCoin() is the name of the function.
    //Custom name is a function to call later. So if no call is made the code will not execute.
    void RotateTheCoin() {

        //transform mean I will use the main class "transform" from one of my library
        //(mean i will move or scale or rotate.)
        //Rotate is the actual function to use.
        //"(" ")" are there to set params of the function.
        //Vector3 Is there to tell we use Axes system ( X Y Z )
        //in the Vector3 we use "up" so we will use Y in positive way
        //" * " is a multiplier sign to tell we rotate it with a power of
        //and "5" is actually the power used to rotate "Script" Holder by 5 on the axe Y in a positive way.
        transform.Rotate(Vector3.up * 5);
    }
}

//So basicly this script try to rotate a mesh that hold the script.
