using System.Collections;

public class TowerAttack : MonoBehaviour {

public float timeBetweenAttacks = 0.5f;
public int attackDamage = 10;

GameObject player;
PlayerHealth playerHealth;
bool playerInRange;
float timer;

void Awake()
{
    player = GameObject.FindGameObjectWithTag ("Player");
    playerHealth = player.GetComponent<PlayerHealth> ();

}

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

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

// Update is called once per frame
void Update () {

    timer += Time.deltaTime;

    if (timer >= timeBetweenAttacks && playerInRange)
        Attack ();
    if (playerHealth.currentHealth <= 0)
        print ("Player's dead");
}

void Attack()
{
    timer = 0f;
    print (playerHealth);
    if (playerHealth.currentHealth > 0)
        playerHealth.TakeDamage (attackDamage);
}
}

我在名为tower的对象上使用此代码，它与istrigger活动的盒式对撞机。在场上产生了多个对象＆＃34; PlayerHealth＆＃34;脚本附加并标记为＆＃34;播放器＆＃34;。但是只有第一个＆＃34;播放器＆＃34;进入箱式对撞机后，它的健康状况将被移除，而其余的＆＃34; Player＆＃34;物品保持健康。

Answer 1

使用“PlayerHealth”在字段上生成多个对象脚本附加并标记为“播放器”。然而只有第一个进入箱式对撞机的“玩家”得到它的健康移除和其余的“玩家”物品保持健康。

playerHealth = player.GetComponent<PlayerHealth> ();代码行只能从一个对象获取PlayerHealth。

要消除多个敌人的健康状况，您需要在每次调用other.GetComponent<PlayerHealth> ()时执行OnTriggerEnter。

void OnTriggerEnter(Collider other)
{
    print(other);
    //Remove health only if the Object is tagged as Player
    if (other.CompareTag("Player"))
    {
        other.GetComponent<PlayerHealth>().TakeDamage(attackDamage);
        playerInRange = true;
    }
}

Answer 2

player = GameObject.FindGameObjectWithTag ("Player");

这是为了设置一个玩家。如果有多个玩家，则其中一个玩家被设置为该变量。 playerHealth = player.GetComponent<PlayerHealth> ();也只是玩家。你应该这样做。

using System.Collections;

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

    GameObject[] players;
    bool playerInRange;
    float timer;

    void Awake()
    {
        players = GameObject.FindGameObjectsWithTag ("Player");
        // FindGameObjectWithTag => FindGameObjectsWithTag
    }

    void OnTriggerEnter(Collider other)
    {
        print (other);
        if (other.tag == "Player")
            playerInRange = true;
    }

    void OnTriggerExit(Collider other)
    {
        if (other.tag == "Player")
            playerInRange = false;
    }

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

        if (timer >= timeBetweenAttacks && playerInRange)
            Attack ();
        for (int i = 0; i < players.Length; i++)
        {
            if (players [i].GetComponent<PlayerHealth> ().currentHealth <= 0)
                print ("Player's dead")
        }
    }

    void Attack()
    {
        timer = 0f;
        print (playerHealth);
        if (playerHealth.currentHealth > 0)
            playerHealth.TakeDamage (attackDamage);
    }
}

如果您想同时在范围内设置TowerAttack Attack()所有玩家，您可以应用上述代码。但是，如果您想要一个接一个地攻击玩家，请将Update()中的函数移动到OnTrigger*方法。那么您可能需要这种方法OnTriggerStay。

你如何消除多个敌人的健康？
