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<Vector3> positions;
}


public enum DistributionType
{
    None,
    test1,
    test2,
    test3,
}

cs 复制代码

[CustomEditor(typeof(Test))]
public class TestEditor : Editor {

    public SerializedObject obj;

    public SerializedProperty distType;
    public SerializedProperty positions;
    public SerializedProperty num;

    void OnEnable()
    {
        obj = new SerializedObject(target);
        distType = obj.FindProperty("distType");
        num = obj.FindProperty("num");
        positions = obj.FindProperty("positions");
    }

    public override void OnInspectorGUI()
    {
        //base.OnInspectorGUI();
        obj.Update();
        if (distType.enumValueIndex == 0)
        {
            EditorGUILayout.PropertyField(positions, true);
        }
        else
        {
            EditorGUILayout.PropertyField(num);
        }
        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。
