统一-在第一波被击败后生成敌人的问题

我正在开发一个具有三种不同类型敌人的unity项目。现在，当游戏开始时，三个敌人中的一个将会出现。到目前为止，一切顺利。问题在于，当我杀死一个敌人时，我希望这种类型的敌人能够不断出现。所以基本上，游戏一开始只有一个敌人，没有其他敌人出现。当我杀死一种类型时，这种类型会反复出现，直到它们可能杀死我。下面是我的代码:

    public bool waveOne = true;
    public float subTime = .5f; //Lab 11 work
    #endregion Member Variables
    #region Member Functions
    void Start ()
    {
    if (waveOne == true) {
            Invoke ("Spawn", spawnTime);
        } 
        else {
            // Call the Spawn function after a delay of the spawnTime and then continue to call after the same amount of time.
            InvokeRepeating ("Spawn", spawnTime, spawnTime);
        }
    }

上面的函数会生成每种类型的一个。

我尝试创建这个函数来调用重复的敌人:

    public void callEnemies()
    {
        waveOne = false;
        InvokeRepeating ("Spawn", spawnTime, spawnTime);
    }

我会在我的死亡函数下的enemyHealth.cs中调用callEnemies。

        public void Death ()
    {
        // The enemy is dead.
        isDead = true;
        // Turn the collider into a trigger so shots can pass through it.
        capsuleCollider.isTrigger = true;
        EnemyManager.Instance.callEnemies();
        // Tell the animator that the enemy is dead.
        anim.SetTrigger ("Dead");
        // Change the audio clip of the audio source to the death clip and play it (this will stop the hurt clip playing).
        enemyAudio.clip = deathClip;
        enemyAudio.Play ();

        #region Lab10 Addition
        // Kill the Enemy (remove from EnemyList)
        // Get the game object associated with "this" EneymHealth script
        // Then get the InstanceID of that game object.
        // That is the game object that needs to be killed.
        EnemyManager.Instance.Kill(this.gameObject.GetInstanceID());
        #endregion // Lab10 Addition
    }

所以现在我的三个敌人中只有一个出来了。但另外两个没有。任何帮助都太好了!

使用System.Collections.Generic

;使用UnityEngine;
