Best practice is to make them separate classes in three different source code files. It is possible to have more than one class in a single source code file by using inner classes. However, I would advise against it in this case, because it would break best practice. And the compiler will still create separate … Read more

You’d use them when you don’t need to give the constructor or method any data. In the case of your ArrayList it’s to make an empty array with a default capacity of 10 elements (OpenJDK implementation). As an abstract example, I can tell you to eat() but I don’t care what you eat, so I … Read more
You can use events to make your scripts “communicate” independently. First you need the gameevents. Make sure you have the script on a gameobject in your scene: using System; using System.Collections; using System.Collections.Generic; using UnityEngine; public class GameEvents : MonoBehaviour { public static GameEvents gameEvents; private void Awake() { gameEvents = this; } public event … Read more
