How to create properties to access the member variables (fields) in a class.

Games

Expose only the important details of an object by correctly recognizing opportunities to implement abstraction

Control access to data within a class by applying encapsulation with getters and setters

Explain the purpose of interfaces, including their functional usability advantages over standard classes  

Make code more secure and usable by correctly implementing the principles of abstraction and encapsulation, including the use of interfaces

Intermediate Scripting

using UnityEngine;
using System.Collections;

public class Player
{
    //Member variables can be referred to as
    //fields.
    private int experience;

    //Experience is a basic property
    public int Experience
    {
        get
        {
            //Some other code
            return experience;
        }
        set
        {
            //Some other code
            experience = value;
        }
    }

    //Level is a property that converts experience
    //points into the leve of a player automatically
    public int Level
    {
        get
        {
            return experience / 1000;
        }
        set
        {
            experience = value * 1000;
        }
    }

    //This is an example of an auto-implemented
    //property
    public int Health{ get; set;}
}


using UnityEngine;
using System.Collections;

public class Game : MonoBehaviour 
{
    void Start () 
    {
        Player myPlayer = new Player();

        //Properties can be used just like variables
        myPlayer.Experience = 5;
        int x = myPlayer.Experience;
    }
}
