速度和旋转问题

问：

我的方块应该在跳跃时旋转 90 度。但是旋转会干扰跳跃高度。起初我尝试实际旋转，现在我正在尝试动画。我试图改变惯性值，但意识到它是只读的。这是我的代码：

using System.Collections.Generic;
using UnityEngine;



public class MoveScript : MonoBehaviour
{
    private bool isGrounded = true;
    public float walkSpeed = 5;
    public float jumpHeight = 7;
    public Rigidbody2D myRigidBody;
    public Transform myTransform;
    public Animator myAnimator;
    //myRigidBody.inertia = 4;
    //private float rotationStep = -30;
    // Start is called before the first frame update
    void Start()
    {

    }
    void OnCollisionEnter2D(Collision2D col)
    {
        isGrounded = true;

    }
    void OnCollisionExit2D(Collision2D col)
    {
        isGrounded = false;

    }
      
    void Update()
    {
        myRigidBody.rotation = 0; //i set the rotation to 0 so that if the player jumps on the corner of a block, they aren't sent in another direction.
        myTransform.Translate(Vector2.right * walkSpeed * Time.deltaTime);
        if (Input.GetMouseButtonDown(0) && isGrounded == true)
        {
            Jump();
            
            myAnimator.SetTrigger("RotateTrigger");
        }      
        void Jump()
        {
            myRigidBody.velocity = new Vector2(0, jumpHeight);
        }
       }
}

我尝试了这个代码，我希望它能工作，但是跳跃高度真的很低，因为它与旋转冲突
