实例化 Unity 2D

Question

我制作了一个脚本，应该每 1 秒产生一个敌人。 但是，一秒钟后它会产生数百个并且不会停止。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PSpawner : MonoBehaviour
{
    public Transform spawny;
    public Transform p;

    // Start is called before the first frame update
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {
        StartCoroutine("Spawn");
    }
    public IEnumerator Spawn()
    {
        yield return new WaitForSeconds(1);
        Instantiate(spawny, p.position, Quaternion.identity);
        yield return null;
    }
}

Answer 1

在您的Spawn协程中使用 while 循环，并在Start启动它，以便它只运行一个实例：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PSpawner : MonoBehaviour
{
    public Transform spawny;
    public Transform p;
    public bool doSpawn;

    // Start is called before the first frame update
    void Start()
    {
        doSpawn = true;
        StartCoroutine("Spawn");
    }

    public IEnumerator Spawn()
    {
        WaitForSeconds wait = new WaitForSeconds(1);

        while (doSpawn)
        {
            yield return wait;
            Instantiate(spawny, p.position, Quaternion.identity);
        }
    }
}
