错误 CS1525：无效的表达式术语“）”

Question

编程新手，我目前正在学习某个教程。 我已经按照代码从视频本身复制了它（手写），但是，unity 给了我标题中的问题。 这是代码：

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

public class Player : MonoBehaviour
{
    [SerializeField] private float moveSpeed = 7f;
    [SerializeField] private GameInput gameInput;

    private bool isWalking;

    private void Update()
    {
        Vector2 inputVector = gameInput.GetMovementVectorNormalized();

        Vector3 moveDir = new Vector3(inputVector.x, 0f, inputVector.y);

        float moveDistance = moveSpeed * Time.deltaTime;
        float playerRadius = .7f;
        float playerHeight = 2f;

        bool canMove = !Physics.CapsuleCast(transform.position, transform.position + Vector3.up * playerHeight, playerRadius, moveDir, moveDistance);

        if (!canMove)
        {
            Vector3 moveDirX = new Vector3(moveDir.x, 0, 0).normalized;
            canMove = !Physics.CapsuleCast(transform.position, transform.position + Vector3.up * playerHeight, playerRadius, moveDirX, moveDistance);

            if (canMove)
            {
                moveDir = moveDirX;
            }

            else
            {
                Vector3 moveDirZ = new Vector3(0, 0, moveDir.z,).normalized;
                canMove = !Physics.CapsuleCast(transform.position, transform.position + Vector3.up * playerHeight, playerRadius, moveDirZ, moveDistance);

                if (canMove)
                {
                    moveDir = moveDirZ;
                }
                else
                {
                    //cannot move
                }
            }
        }
        if (canMove)
        {
            transform.position += moveDir * moveDistance;
        }


        isWalking = moveDir != Vector3.zero;



        float rotateSpeed = 10f;
        transform.forward = Vector3.Slerp(transform.forward, moveDir, Time.deltaTime * rotateSpeed);

    }

    public bool IsWalking()
    {
        return isWalking;
    }
}

根据我的理解，问题应该是少了一个字符或者多了一个。我发现 ( 和 ) 括号的数量是匹配的。问题出在哪里？

Answer 1

第 36 行 - 有一个逗号后跟右括号：

moveDir.z,).标准化;

这是一个多余的逗号或者后面应该有一些变量

Answer 2

你在这一行有错别字 Vector3 moveDirZ = new Vector3(0, 0, moveDir.z,).normalized;

应该是
Vector3 moveDirZ = new Vector3(0, 0, moveDir.z).normalized;

Unity 完美地说明了正在发生的事情，请注意在提问之前您需要完美地复制代码。

如果你是编程新手，这是一个日常问题，你需要在寻求帮助之前了解发生了什么。
