By: Harrison Ferrone

Overview of this book

Learning to program in today’s technical landscape can be a daunting task, especially when faced with the sheer number of languages you have to choose from. Luckily, Learning C# with Unity 2019 removes the guesswork and starts you off on the path to becoming a confident, and competent, programmer using game development with Unity. You’ll start off small by learning the building blocks of programming, from variables, methods, and conditional statements to classes and object-oriented systems. After you have the basics under your belt you’ll explore the Unity interface, creating C# scripts, and translating your newfound knowledge into simple game mechanics. Throughout this journey, you’ll get hands-on experience with programming best practices and macro-level topics such as manager classes and flexible application architecture. By the end of the book, you’ll be familiar with intermediate C# topics like generics, delegates, and events, setting you up to take on projects of your own.

Enemy behavior

This is attached to the Enemy object and it requires a parent GameObject with patrol points, as follows:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;

public class EnemyBehavior : MonoBehaviour
{
public Transform player;
public Transform patrolRoute;
public List<Transform> locations;

private int locationIndex = 0;
private NavMeshAgent agent;
private int _lives = 3;

public int Lives
{
get { return _lives; }
private set
{
_lives = value;

if (_lives <= 0)
{
Destroy(this.gameObject);
Debug.Log("Enemy down.");
}
}
}

void Start()
{
agent = GetComponent<NavMeshAgent>();
player = GameObject.Find("Player").transform;

InitializePatrolRoute();
MoveToNextPatrolLocation();
}

void Update()
{
