统一：如何从列表中删除不活动的gameObject

Question

我做了一个目前在我的箱子对撞机中的gameObjects列表，它的工作原理。但是，当我将游戏对象设置为非活动状态时，

gameObject.SetActive（false）; //消除敌人

gameObject保留在List中而不被删除。如何从另一个类的OnTriggerEnter函数的列表中删除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，这样的事情会做，

PlayerLife类

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

僵尸类

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; 

     } 
    } 

Answer 2

你有更多的方式，我会告诉你一个简单的。

Modificate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); 
} 

或者somithing这样，但它不是好的选择，我想。

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); 
    } 
} 

而且在PlayerLifeClass添加新的方法：

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

或者使用单身人士。在Zombie.cs

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

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

，并使用它：新变量添加到PlayerLifeClass

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