SerializedProperty.FindPropertyRelative

描述

检索当前属性的相对路径处的 SerializedProperty。

当 SerializedProperty 引用复合类型（如结构体、类或数组）时，可以使用此方法按名称查找子属性。

using UnityEngine;
using UnityEditor;

public class SerializePropertyFindPropertyRelative : ScriptableObject
{
    [System.Serializable]
    public struct NestedData
    {
        public int x;
        public int y;
    };
    public NestedData m_data;

    [MenuItem("Example/SerializedProperty FindPropertyRelative Example")]
    static void FindPropertyRelativeExample()
    {
        var scriptableObject = ScriptableObject.CreateInstance<SerializePropertyFindPropertyRelative>();

        // Change the values of the struct using SerializedObject
        using (var serializedObject = new SerializedObject(scriptableObject))
        {
            var data = serializedObject.FindProperty("m_data");

            SerializedProperty x = data.FindPropertyRelative("x");
            x.intValue = 1;

            SerializedProperty y = data.FindPropertyRelative("y");
            y.intValue = 2;

            serializedObject.ApplyModifiedProperties();
        }

        Debug.Log($"Value of data after update: {scriptableObject.m_data.x}, {scriptableObject.m_data.y}");
    }
}
