Unity 自定义编辑器根据枚举值显示变量

public class Test : MonoBehaviour
{
    [HideInInspector]
    [Header("数量")]
    [SerializeField]
    public int num;
 
    [Header("分布类型")]
    [SerializeField]
    public DistributionType distType;
 
    [HideInInspector]
    [Header("位置")]
    [SerializeField]
    public List positions;
 
      [Header("test")]
  [SerializeField]
  List test;
}
 
 
[Serializable]
public class testType
{
    public int id;
    public string name;
}
 
 
public enum DistributionType
{
    None,
    test1,
    test2,
    test3,
}

[CustomEditor(typeof(Test))]
public class TestEditor : Editor {
 
    public SerializedObject obj;
 
    public SerializedProperty distType;
    public SerializedProperty positions;
    public SerializedProperty num;
    public SerializedProperty test;
 
    void OnEnable()
    {
        obj = new SerializedObject(target);
        distType = obj.FindProperty("distType");
        num = obj.FindProperty("num");
        positions = obj.FindProperty("positions");
 
        test = obj.FindProperty("test");
    }
 
    public override void OnInspectorGUI()
    {
        //base.OnInspectorGUI();
        obj.Update();
        if (distType.enumValueIndex == 0)
        {
            EditorGUILayout.PropertyField(positions, true);
        }
        else
        {
            EditorGUILayout.PropertyField(num);
        }
        EditorGUILayout.PropertyField(test,true);
        obj.ApplyModifiedProperties();
 
    }
}

在数据类中（文中是Test类）数组类的字段在开启基类的base.OnInspectorGUI();不能用[HideInInspector]，否则会无法显示数组内容。
