箱子在地面上和向前移动时旋转

问：

我正在尝试创建一个可以跳跃、前进/后退和向右/向左移动的移动盒子。 但是当这个盒子接触或用对撞机接触某物时，它开始旋转并且不允许我移动它/不是很多，所以它开始绕圈（小圈子）。

盒子有 3 个组件：
1 - 未设置为触发
的盒子碰撞器 2 - 不使用重力的刚体（我在脚本中这样做）
3 - 我的脚本移动播放器

这是我的自定义脚本：

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

[RequireComponent(typeof(Rigidbody))]
[RequireComponent(typeof(Collider))]

public class PlayerMovement : MonoBehaviour {
    public float moveSpeed = 9f;
    public float airMoveSpeed = 0.6f;
    public float jumpSpeed = 8f;
    public float gravity = 20f;
    public float groundDrag = 6f;
    public float airDrag = 4f;
    public Camera playerCamera;
    public float sensitivity = 2f;
    public float lookXLimit = 45f;
    public GroundCheck groundCheck;

    Vector3 moveDirection = Vector3.zero;
    Rigidbody rb;
    float rotationX = 0;

    void Start()
    {
        rb = gameObject.GetComponent<Rigidbody>();

        isGrounded = false;

        // Lock cursor
        Cursor.lockState = CursorLockMode.Locked;
        Cursor.visible = false;
    }

    void Update()
    {
        CheckGround();
        MovePlayer();
        Gun();
        ControlDrag();
    }

    void CheckGround() {
        isGrounded = groundCheck.isGrounded;
    }

    void MovePlayer() {
        // Recalculate move direction based on axes
        Vector3 forward = transform.TransformDirection(Vector3.forward);
        Vector3 right = transform.TransformDirection(Vector3.right);
        float curSpeedX = canMove ? moveSpeed * Input.GetAxis("Vertical") : 0;
        float curSpeedY = canMove ? moveSpeed * Input.GetAxis("Horizontal") : 0;
        moveDirection = (forward * curSpeedX) + (right * curSpeedY);

        // moveDirection.y -= gravity * 1000;

        if (Input.GetButton("Jump") && canMove && isGrounded)
        {
            rb.AddForce(transform.up * jumpSpeed, ForceMode.Impulse);
        }

        // Move the player
        if(isGrounded) {
            // transform.position += moveDirection;
            rb.AddForce(moveDirection * Time.deltaTime, ForceMode.Acceleration);
        } else {
            // transform.position += moveDirection;
            rb.AddForce(moveDirection * Time.deltaTime * airMoveSpeed, ForceMode.Acceleration);
        }

        // Player and Camera rotation
        if (canMove)
        {
            rotationX += -Input.GetAxis("Mouse Y") * sensitivity;
            rotationX = Mathf.Clamp(rotationX, -lookXLimit, lookXLimit);
            playerCamera.transform.localRotation = Quaternion.Euler(rotationX, 0, 0);
            transform.rotation *= Quaternion.Euler(0, Input.GetAxis("Mouse X") * sensitivity, 0);
        }
    }

    void ControlDrag() {
        if(isGrounded) rb.drag = groundDrag;
        else rb.drag = airDrag;
    }
}
