使用Rigidbody2D.MovePosition结合鼠标Delta导致移动抖动问题求助

• 开发自定义光标解谜游戏，使用Unity新输入系统
• 直接跟随鼠标Delta移动光标时流畅，但无法处理碰撞
• 使用Rigidbody2D.MovePosition或设置Velocity实现带碰撞移动时，出现移动不流畅、位置偏移、抖动问题
• 已尝试调整Rigidbody2D参数、将移动代码移至FixedUpdate，均未解决
• Unity版本：2020.3.26f1

using UnityEngine;
using UnityEngine.InputSystem;

public class CursorScript : MonoBehaviour
{
    #region Input
    private PlayerInput playerInput;

    private InputAction mousePosition;
    private InputAction deltaMousePosition;
    private InputAction click;

    private void Awake()
    {
        playerInput = GetComponent<PlayerInput>();
        mousePosition = playerInput.actions["MousePosition"];
        click = playerInput.actions["Click"];
        deltaMousePosition = playerInput.actions["MouseDelta"];
    }

    #endregion

    public Camera cam;
    public float sensitivity;
    public SpriteRenderer spriteRenderer;
    public Sprite[] sprites;

    void Start()
    {
        Cursor.lockState = CursorLockMode.Locked;
        Cursor.visible = false;
    }

    void Update()
    {
        Vector2 realMousePosition = cam.ScreenToWorldPoint(mousePosition.ReadValue<Vector2>());

        // 光标移动代码
        GetComponent<Rigidbody2D>().MovePosition(new Vector2(transform.position.x, transform.position.y) + deltaMousePosition.ReadValue<Vector2>() * sensitivity);
        
        spriteRenderer.sprite = sprites[0];
        if (click.ReadValue<float>() == 1)
            spriteRenderer.sprite = sprites[1];
    }
}
