本文介绍了一个基于Unity的游戏生命值与攻击系统的实现。通过PlayerHealth.cs脚本，玩家角色具有生命值，并能受到伤害；EnemyAttack.cs脚本使敌人能够攻击玩家，造成伤害。系统包括生命值滑条显示、死亡动画、重新加载关卡等功能。

1添加PlayerHealth.cs到Player

using UnityEngine;
using UnityEngine.UI;
using System.Collections;
using UnityEngine.SceneManagement;


public class PlayerHealth : MonoBehaviour
{
    public int startingHealth = 100;
    public int currentHealth;
    public Slider healthSlider;
    public Image damageImage;
    public AudioClip deathClip;
    public float flashSpeed = 5f;
    public Color flashColour = new Color(1f, 0f, 0f, 0.1f);


    Animator anim;
    AudioSource playerAudio;
    PlayerMovement playerMovement;
    //PlayerShooting playerShooting;
    bool isDead;
    bool damaged;


    void Awake ()
    {
        anim = GetComponent <Animator> ();
        playerAudio = GetComponent <AudioSource> ();
        playerMovement = GetComponent <PlayerMovement> ();
        //playerShooting = GetComponentInChildren <PlayerShooting> ();
        currentHealth = startingHealth;
    }


    void Update ()
    {
        if(damaged)
        {
            damageImage.color = flashColour;
        }
        else
        {
            damageImage.color = Color.Lerp (damageImage.color, Color.clear, flashSpeed * Time.deltaTime);
        }
        damaged = false;
    }


    public void TakeDamage (int amount)
    {
        damaged = true;

        currentHealth -= amount;

        healthSlider.value = currentHealth;

        playerAudio.Play ();

        if(currentHealth <= 0 && !isDead)
        {
            Death ();
        }
    }


    void Death ()
    {
        isDead = true;

        //playerShooting.DisableEffects ();

        anim.SetTrigger ("Die");

        playerAudio.clip = deathClip;
        playerAudio.Play ();

        playerMovement.enabled = false;
        //playerShooting.enabled = false;
    }


    public void RestartLevel ()
    {
        SceneManager.LoadScene (0);
    }
}

把相应的对象赋值到PlayerHealth.cs的public变量：

2.添加EnemyAttack .cs到enemy

using UnityEngine;
using System.Collections;

public class EnemyAttack : MonoBehaviour
{
    public float timeBetweenAttacks = 0.5f;
    public int attackDamage = 10;


    Animator anim;
    GameObject player;
    PlayerHealth playerHealth;
    //EnemyHealth enemyHealth;
    bool playerInRange;
    float timer;


    void Awake ()
    {
        player = GameObject.FindGameObjectWithTag ("Player");
        playerHealth = player.GetComponent <PlayerHealth> ();
        //enemyHealth = GetComponent<EnemyHealth>();
        anim = GetComponent <Animator> ();
    }


    void OnTriggerEnter (Collider other)
    {
        if(other.gameObject == player)
        {
            playerInRange = true;
        }
    }


    void OnTriggerExit (Collider other)
    {
        if(other.gameObject == player)
        {
            playerInRange = false;
        }
    }


    void Update ()
    {
        timer += Time.deltaTime;

        if(timer >= timeBetweenAttacks && playerInRange/* && enemyHealth.currentHealth > 0*/)
        {
            Attack ();
        }

        if(playerHealth.currentHealth <= 0)
        {
            anim.SetTrigger ("PlayerDead");
        }
    }


    void Attack ()
    {
        timer = 0f;

        if(playerHealth.currentHealth > 0)
        {
            playerHealth.TakeDamage (attackDamage);
        }
    }
}
