Question

这是我的代码，我只是在关注一个 youtube 教程，我不知道我做错了什么。 （现在这是完整的代码，而不仅仅是开始。

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


    public class PlayerLocomotion : MonoBehaviour
    {
        Transform cameraObject;
        InputHandler inputHandler;
        Vector3 moveDirection;

        [HideInInspector]
        public Transform myTransform;

        public new Rigidbody rigidbody;
        public GameObject normalCamera;

        [Header("Stats")]
        [SerializeField]
        float movementSpeed = 5;
        [SerializeField]
        float rotationSpeed = 10;

        void Start()
        {
            rigidbody = GetComponent<Rigidbody>();
            inputHandler = GetComponent<InputHandler>();
            cameraObject = Camera.main.transform;
            myTransform = transform;

        }

        public void Update()
        {
            float delta = Time.deltaTime;

            inputHandler.TickInput(delta);

            moveDirection = cameraObject.forward * inputHandler.vertical;
            moveDirection += cameraObject.right * inputHandler.horizontal;
            moveDirection.Normalize();

            float speed = movementSpeed;
            moveDirection *= speed;

            Vector3 projectedVelocity = Vector3.ProjectOnPlane(moveDirection, normalVector);
            rigidbody.velocity = projectedVelocity;


        }

        #region Movement
        Vector3 normalVector;
        Vector3 targetPosition;

        private void HandleRotation(float delta)
        {
            Vector3 targetDir = Vector3.zero;
            float moveOverride = inputHandler.moveAmount;

            targetDir = cameraObject.forward * inputHandler.vertical;
            targetDir += cameraObject.right * inputHandler.horizontal;

            targetDir.Normalize();
            targetDir.y = 0;

            if (targetDir == Vector3.zero)
                targetDir = myTransform.forward;

            float rs = rotationSpeed;

            Quaternion tr = Quaternion.LookRotation(targetDir);
            Quaternion targetRotation = Quaternion.Slerp(myTransform.rotation, tr, rs * delta);

            myTransform.rotation = targetRotation;
        }

        #endregion
    }

我尝试查找资料，但没有任何内容与我所面临的相似。

stack overflow 还想让我说更多，但不太确定还有什么要说的，所以我将继续输入内容，直到红点消失。
