Getting To Know Unity

The User Interface

A: Object Hierarchy | B: Scene Display | C: Object Inspector

D: File Hierarchy | E: Game Display (Camera) | F: Console Log

Assets

Files in your project's asset directory

Images: .png, .jpg, .svg
Audio: .mp3, .oqq, .wav
Video: .ogv, .vp8, .webm
Data: .xml, .json, .csv

Scenes

Scenes are individual levels in a game
Instantiated Game Entities
Data is lost when transferring between scenes**
Saved as individual files in a unity project

Components

Scene Manager: Controller for transferring between scenes

Game Programming

The MonoBehavior Object

One Object To Rule Them All

Important Functions:

Start: Called on the first frame of the game
Update: Called every frame of the game
Fixed Update: Update function except it's better for physics

Basic Mono Script

                    
                        using System;
                        using UnityEngine;

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