Question

我正在游戏中实施烟雾预制。想法是创建预制件的3个不同实例（在不同位置），然后根据切换按钮销毁它们。实例没有被破坏的问题，我不明白为什么。

这是我的剧本：

class Smoke1 : MonoBehaviour
    {
    public GameObject myPrefab;
    public GameObject canvasObject;

    public static GameObject newSmoke1;
    public static GameObject newSmoke2;
    public static GameObject newSmoke3;

    public int toggle1;
    public int toggle2;
    public int toggle3;

    public Vector3 smokeposition1 = new Vector3 (397, -394, 90);
    public Vector3 smokeposition2 = new Vector3(414, -402, 90);
    public Vector3 smokeposition3 = new Vector3(432, -410, 90);

    string newSmoke;


    void Start()
        {
        i = 1;
        toggle1 = 2;
        toggle2 = 2;
        toggle3 = 2;
        newinstance(smokeposition1, newSmoke1);
        newinstance(smokeposition2, newSmoke2);
        newinstance(smokeposition3, newSmoke3);
        }

    void Update()
        {

        togglecheck(ThermoElectric.t1Bool, toggle1, newSmoke1, smokeposition1);
        togglecheck(ThermoElectric.t2Bool, toggle2, newSmoke2, smokeposition2);
        togglecheck(ThermoElectric.t3Bool, toggle3, newSmoke3, smokeposition3);
        }

    void newinstance(Vector3 smokeposition, GameObject smokeinstance)
        {
        smokeinstance = Instantiate(myPrefab, smokeposition, Quaternion.Euler(-90, 0, 0)) as GameObject;
        smokeinstance.transform.SetParent(canvasObject.transform, false);
        smokeinstance.transform.localScale = new Vector3(1, 1, 1);

        smokeinstance.GetComponent<ParticleSystem>().startColor = new Color(0.1f, 0.1f, 0.1f, 1);

        }

    void togglecheck(bool turbine, int togglei, GameObject smokeinstancet, Vector3 smokeposition)
        {

        if (turbine == true && togglei == 1)
            {
            newinstance(smokeposition, smokeinstancet);
            togglei = 2;
            }

        if (turbine == false && togglei == 2)
            {
            Destroy(smokeinstancet, 0.1f);
            togglei = 1;
            }
        }
}

bool正在工作，如果条件得到满足，但预制件不会被破坏。你可以帮忙吗？

bool正在工作，if条件得到满足，但预制件不要被破坏。你可以帮忙吗？

1 。你不应该摧毁预制件。您应该只销毁使用Instantiate创建的GameObject。

2 。从GameObject中删除静态。我相信你不需要那个。

如果您是％100，请确保满足if条件，那么问题就是newinstance。如果您不确定，请将Debug.Log放在if (turbine == false && togglei == 2)内以验证这一点条件得到满足，因为没有它，Destroy(smokeinstancet, 0.1f);不会被调用。

newinstance功能问题。

void newinstance(Vector3 smokeposition, GameObject smokeinstance)
{
    smokeinstance = Instantiate(myPrefab, smokeposition, Quaternion.Euler(-90, 0, 0)) as GameObject;
    smokeinstance.transform.SetParent(canvasObject.transform, false);
    smokeinstance.transform.localScale = new Vector3(1, 1, 1);

    smokeinstance.GetComponent<ParticleSystem>().startColor = new Color(0.1f, 0.1f, 0.1f, 1);
}

smokeinstance = Instantiate(myPrefab, smokeposition, Quaternion.Euler(-90, 0, 0)) as GameObject;代码将实例化的GameObject分配给名为smokeinstance的参数中的局部变量。它不会将其分配给传递给它的GameObjects，例如newSmoke1，newSmoke2和newSmoke3。

newinstance(smokeposition1, newSmoke1);
newinstance(smokeposition2, newSmoke2);
newinstance(smokeposition3, newSmoke3);

<强>解：

您有2个解决方案：

1 。使用ref或out关键字。在这种情况下，我们只会使用ref关键字。

void newinstance(Vector3 smokeposition, ref GameObject smokeinstance)
{
 ......
}

然后在调用时使用ref。

newinstance(smokeposition1, ref newSmoke1);
newinstance(smokeposition2, ref newSmoke2);
newinstance(smokeposition3, ref newSmoke3);

2 。使newinstance函数返回GameObject而不是void。

GameObject newinstance(Vector3 smokeposition)
{
    GameObject smokeinstance = Instantiate(myPrefab, smokeposition, Quaternion.Euler(-90, 0, 0));
}

然后调用它：

newSmoke1 = newinstance(smokeposition1);
newSmoke2 = newinstance(smokeposition2);
newSmoke3 = newinstance(smokeposition3);

任何一个都可以解决你的问题。
