Unity 2D报错CS1061：Quaternion未包含eularAngles定义问题求助

实现弹球游戏中按下A键时控制挡板旋转的功能。

CS1061: Quaternion does not contain a definition for eularAngles and no accessible extension method eularAngles accepting a first argument of type Quaternion could be found (are you missing a using directive or an assembly reference?)

编译失败由两个错误导致，与Quaternion归一化、类声明缺失无关：

• 属性名拼写错误：欧拉角对应属性的正确写法为eulerAngles，原代码误将euler拼写为eular（第二个e错写为a）
• 属性调用路径错误：eulerAngles是Transform类的直接成员，Quaternion类型本身未定义该属性，无需通过myTransform.rotation（Quaternion类型实例）访问

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class paddleLeft : MonoBehaviour{

    private Transform myTransform;

    void Start() {
        myTransform = gameObject.transform;
    }

    void Update() {
        if (Input.GetKey(KeyCode.A)) {
            var ourRotation = myTransform.eulerAngles;
            var newRotation = new Vector3(ourRotation.x, ourRotation.y, ourRotation.z + (5 * Time.deltaTime));
            myTransform.rotation = Quaternion.Euler(newRotation);
        }
    }
}
