Introduction to Unity Scripting API

The Unity scripting API is a collection of namespaces. API stands for Application Programming Interface. It allows 2 applications to talk to each other. Think of it as a bundle/box of code that your code can interface (talk) to.

What is a Namespace?

A namespace is a collection of classes, events, enumerations, delegates, interfaces etc that handle a specific task each. So each namespace will handle a specific task each.

The most common namespaces are:

1. UnityEngine namespace: collection of pre-built classes, events, interfaces etc that allow us to work with the Unity engine.
2. UnityEditor namespace: UnityEditor namespace is a collection of pre-built classes, events, structures, enumerations, delegates, interfaces etc that allow us to extend the functionality of the Unity3D editor.
3. System namespace: part of the .NET framework which is used behind the scenes by the Unity3d game engine. It is a is a collection of, events, interfaces, delegates , structures, enumerations etc that allow us to create and use common data structures

Essentially namespaces are like containers for classes and we can access all the classes of these namespaces in our script.

//using imports a namespace
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CubeController : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    // Update is called once per frame
    void Update()
    {

    }
}
