The code in this chapter

Let's take a look at the code again to make sure we are on the same page.

The code for Collectable.cs is as follows:

using UnityEngine; 
using System.Collections; 
 
public class Collectable : MonoBehaviour { 
   
  bool isCollected = false; 
 
  void Show() { 
    this.GetComponent<SpriteRenderer>().enabled = true; 
    this.GetComponent<CircleCollider2D>().enabled = true; 
    isCollected = false; 
  } 
 
  void Hide() { 
    this.GetComponent<SpriteRenderer>().enabled = false; 
    this.GetComponent<CircleCollider2D>().enabled = false; 
  } 
 
 
  void Collect() { 
 
    isCollected = true; 
    Hide(); 
    GameManager.instance.CollectedCoin(); 
  } 
 
  void OnTriggerEnter2D(Collider2D other) { 
     
    if (other.tag == "Player") { 
      Collect(); 
    } 
  }   
} 

Here is the code for HealthPoint:

using UnityEngine;
 using System.Collections;

 public class HealthPoint : MonoBehaviour {

     bool isCollected = false;

     void Show...
