One last code implementation I would like to make before I close out the chapter, is to make sure that when we are in attack mode for the player character, the hit points will affect the NPC that it is intended for automatically. In other words, determine which NPC is closest to us based on our distance and view angle toward the NPC.
We have already created the logic to determine these quantities for the NPC character. We now need to implement something similar for the player character. Let's take a look at a partial listing of the code changes we need to make for the BarbarianCharacterMovement.cs script:
using UnityEngine;
namespace com.noorcon.rpg2e
{
public class BarbarianCharacterController : MonoBehaviour
{
public Animator animator;
public float directionDampTime;
public float speed = 6.0f;
public float h = 0.0f;
public float v = 0.0f;
bool attack = false;
bool punch = false;
bool run = false;
bool jump = false;
[HideInInspector]
public bool die = false;
bool dead ...
