    Namespaces in Unity 3D :

    Namespaces are container of the classes. Namespaces help us to organize the scripts. When we create a new C# script in Monodevelop, two namespaces are included at the top, these are ' using UnityEngine; ' and ' using System.Collection; ' . We can access all the classes of these namespaces in our script. To put a class in namespace we need to surround the class with the namespace.

    For Example : Use the keyword namespace and give any name to this namespace.


    using UnityEngine;
    using System.Collections;
    
    namespace DemoNamespace
    {
        public class DemoClass1 : MonoBehaviour 
        {
            void Start () 
            {
                Debug.Log("Namespace is created..");
            }
        }
    }
    

    There are three ways to use the classes of the namespace -

    First : By using the 'using' directive at the top

    using UnityEngine;
    using System.Collections;
    using DemoNamespace;
    
     public class DemoClass2 : MonoBehaviour 
        {
            void Start () 
            {
                Debug.Log("First way to use the classes of namespace.");
            }
        }
    

    Second : Access the classes using dot operator

    using UnityEngine;
    using System.Collections;
    
     public class DemoClass3 : MonoBehaviour 
        {
            void Start () 
            {
                DemoNamespace.DemoClass1 MyClass = new DemoNamespace.DemoClass1();
                Debug.Log("Second way to use the classes of namespace.");
            }
        }
    

    Third : To put the class in the namespace

    using UnityEngine;
    using System.Collections;
    namespace DemoNamespace
    {
        public class DemoClass4 : MonoBehaviour 
        {
            void Start () 
            {
                DemoClass1 MyClass= new DemoClass1();
                Debug.Log("Third way to use the classes of namespace.");
            }
        }
    }
    

    Thankyou !
    Happy Coding !
