【问题描述】：

当Player 用Raycast 射击Zombie 时，它应该会损坏Zombie(clone) 直到它被摧毁。但是，来自Player 的损坏会损坏变量currentHealth 上的一般Zombie 类，而不是每个Zombie GameObject 上的currentHealth。此外，即使游戏从开始重新开始，currentHealth 的值仍然存在。

public class Zombie : MonoBehaviour
{
    public int currentHealth = 2;

    public void Damage(int damageAmount)
    {
        //subtract damage amount when Damage function is called
        currentHealth -= damageAmount;

        //Check if health has fallen below zero
        if (currentHealth <= 0) 
        {
            //if health has fallen below zero, deactivate it 
            gameObject.SetActive (false);

            //Destroy(gameObject);
        }
        Debug.Log(name + currentHealth);
    }    
}

 public class Player : MonoBehaviour
    {
        public RaycastHit hit;
        public int gunDamage = 1;
        public Zombie zombie;
        public Camera fpsCamera;
        public int weaponRange = 50;
        private int layerMask = 1 << 9;

        void Start()
        {
            spawnPoints = playerSpawnPoint.GetComponentsInChildren<Transform>();
           // bullet = GetComponent<GameObject>();
        }

        void LazerBeam()
        {
            Vector3 rayOrigin = fpsCamera.ViewportToWorldPoint(new Vector3(0.5f, 0.5f, 0f));
            Debug.DrawRay(rayOrigin, Vector3.forward * weaponRange, Color.green);

            if (Physics.Raycast(rayOrigin, fpsCamera.transform.forward, out hit, weaponRange, layerMask))
            {
                zombie.Damage(gunDamage); //kills zombie
                Debug.Log(name + " " + zombie);
            }
            Debug.Log(hit.collider);
        }

        void Update() 
        {
            if (Input.GetKeyDown(KeyCode.Z))
            {
                LazerBeam();
            }
        }

【解决方案1】：

您当前正在对附加在玩家身上的Zombie 施加伤害，而不是附加在被击中对象上的那个。您可以从RaycastHit hit 获得参考。

if (Physics.Raycast(rayOrigin, fpsCamera.transform.forward, out hit, weaponRange, layerMask))
{
    Zombie zombieHit = hit.transform.gameObject.GetComponent<Zombie>();
    zombieHit.Damage(gunDamage); //kills zombie
    Debug.Log(name + " " + zombieHit);
}
