    private void UpdateList(bool destroy)
    {
        GameObject go = GameObject.Find("Main Camera");
        var list = go.GetComponent<PatrolOverTerrain>().Targets;
        if (destroy == false)
        {
            list.AddRange(createdObjects);
            go.GetComponent<PatrolOverTerrain>().Targets = list;
        }

        if (destroy == true)
        {
            list.Clear();
            go.GetComponent<PatrolOverTerrain>().Targets.Clear();
        }
    }
}

而是将脚本附加到我想要克隆的每个gameObject，我想使用对象数组。

例如，让我说我在数组中有2个对象，现在我想在检查器中让每个元素都有自己的属性。当我将属性设置为每个元素的子元素时，它将仅对特定元素生效。

相反，所有元素的一般属性都是从Y偏移量设置此属性，直到最后一个设置兰德标度Z Max为每个元素的子项。所以我可以设置每个元素的属性。

所以我可以扩展每个元素并查看他的属性。

顺便说一下：如何更改随机数，例如：设置Rand Scale X Min和设置Rand Scale X Min将在一行而不是两行？喜欢：

设置Rand Scale X Min Max 设置Rand Scale Y Min Max 设置Rand Scale Z Min Max

这样做的好方法是创建自定义类，然后创建该类的实例数组，但它需要更多的行。如果您想详细了解此搜索ISerializationCallbackReceiver。

最简单的可能是将变量包装在struct中，如下所示。然后，您可以将它们“解包”到您的课程中。这取决于你想要的东西。

using UnityEngine;
using System;

public class InstantiateObjects : MonoBehaviour {

    public ObjectsToInst[] objectsToInstantiate;

    [Serializable]
    public struct ObjectsToInst
    {
        public GameObject objectToInstantiate;
        public Terrain terrain;
        public float yOffset;
        public int numberOfObjectsToCreate;
        public bool parent;
        public bool randomScale;
        public float setRandScaleXMin, setRandScaleXMax;
        public float setTandScaleYMin, setTandScaleYMax;
        public float setTandScaleZMin, setRandScaleZMax;
    }
}

如何为gameObject数组中的每个元素添加属性？
