如何在编辑器中显示和修改数组Window？

Question

我的 CustomEditor class 中有 GameObject 数组字段，派生自 UnityEngine.Editor。我需要能够显示（绘制）并让用户能够修改该数组。

就像 Unity 的 Inspector 对从 ScriptableObject 派生的对象的可序列化字段执行此操作一样。例如。在检查器中显示材料数组：

Answer 1

public GameObject[] yourGameObjects;

然后在检查器中设置您的大小，然后应该会打开字段。

Answer 2

向您的脚本添加一个 public 数组

public GameObject[] myObjects

Answer 3

SerializedObject 参考你的编辑器对象，然后找到任何需要的属性，绘制它，并应用修改：

public class MyEditorWindow : EditorWindow
{
    [MenuItem("Window/My Editor Window")]
    public static void ShowWindow()
    {
        GetWindow<MyEditorWindow>();
    }

    public string[] Strings = { "Larry", "Curly", "Moe" };

    void OnGUI()
    {
        // "target" can be any class derived from ScriptableObject 
        // (could be EditorWindow, MonoBehaviour, etc)
        ScriptableObject target = this;
        SerializedObject so = new SerializedObject(target);
        SerializedProperty stringsProperty = so.FindProperty("Strings");

        EditorGUILayout.PropertyField(stringsProperty, true); // True means show children
        so.ApplyModifiedProperties(); // Remember to apply modified properties
    }
}

我设法用一个 for 循环和一个额外的 int 做到了：

using UnityEditor;
using UnityEngine;

public class RockSpawner : EditorWindow
{
    int rockCollectionSize = 0;
    GameObject[] rockCollection;

    [MenuItem("Tools/Rock Spawner")]
    public static void ShowWindow()
    {
        GetWindow(typeof(RockSpawner));
    }

    void OnGUI()
    {
        rockCollectionSize = EditorGUILayout.IntField("Rock collection size", rockCollectionSize);
        if (rockCollection != null && rockCollectionSize != rockCollection.Length)
            rockCollection = new GameObject[rockCollectionSize];
        for (int i = 0; i < rockCollectionSize; i++)
        {
            rockCollection[i] = EditorGUILayout.ObjectField("Rock " + i.ToString(), rockCollection[i], typeof(GameObject), false) as GameObject;
        }
    }
}

最佳答案对我来说效果不佳，因为属性没有更新，因此我将声明行移到了 OnEnable 函数中，您不想一遍又一遍地声明它们）和用于 so.Update() 更新更改的变量。

using UnityEngine;
using UnityEditor;

public class MyEditorWindow : EditorWindow
{
    [MenuItem("Window/My Editor Window")]
    public static void ShowWindow()
    {
        GetWindow<MyEditorWindow>();
    }

    public string[] Strings = { "Larry", "Curly", "Moe" };
    SerializedObject so;

    private void OnEnable()
    {
        ScriptableObject target = this;
        so = new SerializedObject(target);
    }

    void OnGUI()
    {
        // "target" can be any class derived from ScriptableObject 
        // (could be EditorWindow, MonoBehaviour, etc)
        so.Update();
        SerializedProperty stringsProperty = so.FindProperty("Strings");

        EditorGUILayout.PropertyField(stringsProperty, true); // True means show children
        so.ApplyModifiedProperties(); // Remember to apply modified properties
    }
}
