Unity：如何从列表中删除不活动的游戏对象

Question

我制作了一个当前在我的盒子碰撞器中的游戏对象列表，它可以工作。但是，当我将游戏对象设置为非活动时，

gameObject.SetActive(false); // 消灭敌人

游戏对象保留在列表中而不会被删除。如何从另一个类的 OnTriggerEnter 函数的 List 中删除 gameObject？

PlayerLifeClass：

     private List<GameObject> ObjectsInRange = new List<GameObject>();
        public void OnTriggerEnter(Collider collider)
        {
            if (collider.tag != "Player" && collider.tag == "Zombie")
            {
                ObjectsInRange.Add(collider.gameObject);
                damage = ObjectsInRange.Count; //amount of zombies inside collider
               //***Over here***

                zombie.DamagePlayer(damage);
                Debug.Log(damage);
            }
        }
        public void OnTriggerExit(Collider collider)
        {
            if (collider.tag != "Player" && collider.tag == "Zombie")
            {
                //Probably you'll have to calculate wich object it is
                ObjectsInRange.Remove(collider.gameObject);
                Debug.Log(ObjectsInRange);
            }
        }

ZombieClass:

    public class Zombie : MonoBehaviour
    {
        public int currentHealth;
        private Player player;
        private PlayerLifeCollider playerCollider;

        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); //***Over here***

            }

   public void DamagePlayer(int damage)
    {
         player.Life(damage);
      }
   }

Answer 1

如果我明白你想要什么，这样的事情就可以了，

PlayerLife 类

public static List<GameObject> ObjectsInRange = new List<GameObject>();

僵尸班

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
            PlayerLife.ObjectsInRange.Remove(gameObject); 
            gameObject.SetActive(false); //***Over here***
            //You can also do a Destroy(gameObject) if you'd like;

        }
    }

你有更多方法，我教你一个简单的。

修改你的僵尸类：

public bool Damage(int damageAmount)
{
    currentHealth -= damageAmount;
    if (currentHealth <= 0)
    {
        gameObject.SetActive(false); //***Over here***
        return true; 
    }
    return false;
}

和 PlayerLifeClass：

if (collider.tag != "Player" && collider.tag == "Zombie"){
    ObjectsInRange.Add(collider.gameObject);
    damage = ObjectsInRange.Count; //amount of zombies inside collider
    if(collider.GetComponent<Zombie>().Damage(damage)){
        // if zombie dead, remove him.
        ObjectsInRange.Remove(collider.gameObject);
    }
    Debug.Log(damage);
}

或类似的东西，但我认为这不是一个好的选择。

void Start(){
   playerLifeClass = GameObject.FindGameObjectWithTag("Player")>GetComponent<PlayerLifeClass>();
}
public bool Damage(int damageAmount)
{
    currentHealth -= damageAmount;
    if (currentHealth <= 0)
    {
    //if health has fallen below zero, deactivate it 
       gameObject.SetActive(false); //***Over here***
       playerLifeClass.RemoveZombie(gameObject);
    }
}

并在 PlayerLifeClass 中添加新方法：

public void RemoveZombie(GameObject zomb){
   ObjectsInRange.Remove(zomb);
}

或者使用 Singletons。 将新变量添加到 PlayerLifeClass：

...
public static PlayerLifeClass instance;
public List<GameObject> ObjectsInRange = new List<GameObject>();
...

void Start(){
    instance = this;
    ...
}

并在 Zombie.cs 中使用它：

 if (currentHealth <= 0){
    gameObject.SetActive(false); //***Over here***
    PlayerLifeClass.instance.ObjectsInRange.Remove(gameObject);
 }
