Question

我的代码工作正常，但我需要将预制件限制为仅5次。我想使用for循环.....

using UnityEngine;
using System.Collections;

public class theScript : MonoBehaviour {
    public GameObject prefab1;
    // Use this for initialization
    void Start () {
        InvokeRepeating ("Instant_", 1f, 1f);
    }

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

    }

    void Instant_(){
        Instantiate (prefab1, transform.position, transform.rotation );
    }
}

Answer 1

避免使用Invoke或InvokeRepeating等功能。由于您通过 name 引用函数，如果更改它，Invoke调用中的字符串将不会更新。此外，在使用@bismute方法更改场景或退出游戏之前，Instant_方法将被无用地调用。

我建议您使用协同程序。和奖金，你将使用foor循环！ ; d

using UnityEngine;
using System.Collections;

public class theScript : MonoBehaviour {
    public GameObject prefab1;
    public int MaxInstantiation = 5;

    void Start ()
    {
        StartCoroutine( InstantiatePrefab(1) ) ;
    }

    private IEnumerator InstantiatePrefab( float delay = 1f )
    {
        WaitForSeconds waitDelay = new WaitForSeconds( delay ) ;
        for( int instantiateCount = 0 ; instantiateCount < MaxInstantiation ; ++instantiateCount )
        {
            yield return waitDelay ;
            Instantiate (prefab1, transform.position, transform.rotation ) ;
        }
        yield return null ;
    }
}

有没有理由使用'for'声明？怎么样？

using UnityEngine;
using System.Collections;

public class theScript : MonoBehaviour {
    public GameObject prefab1;
    public int FiveTimeCheck;

    // Use this for initialization
    void Start () {
        FiveTimeCheck = 0;
        InvokeRepeating ("Instant_", 1f, 1f);
    }

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

    }

    void Instant_(){
        if(FiveTimeCheck <= 5)
        {
            FiveTimeCheck += 1;
            Instantiate (prefab1, transform.position, transform.rotation );
        }
    }
}
