Following a path

A path is a sequence of points in the game, connecting a point A to a point B. There are many ways to build a path. Usually, a path is generated by other game systems such as pathfinding (see Chapter 7, A* Pathfinding); however, in our demo, we construct the path by hand using waypoints. So first, we write a Path.cs script that takes a list of game objects as waypoints and create a path out of them.

Path script

Let's look at the path script responsible for managing the path for our objects. Consider the following code in the Path.cs file:

using UnityEngine;
public class Path : MonoBehaviour {
    public bool isDebug = true;
    public Transform[] waypoints;
    public float Length {
        get {
            return waypoints.Length;
        }
