如何修复多人游戏口吃

由于某些原因，其他球员的移动是"口吃"。我知道这是一个常见的问题，人们跑进光子，所以想知道如果有人知道我怎么能解决它?

这是我的玩家移动代码:

public float SmoothingDelay = 5;
public void Start() 
{
    GetComponent<SmoothSyncMovement>().enabled = true; //This is the name of this script
}
public void OnPhotonSerializeView(PhotonStream stream, PhotonMessageInfo info)
{
    if (stream.isWriting)
    {
        //We own this player: send the others our data
        stream.SendNext(rb2D.position);
        stream.SendNext(rb2D.rotation); 
    }
    else
    {
        //Network player, receive data
        correctPlayerPos = (Vector3)stream.ReceiveNext();
    }
}
public void Update()
{
    if (!photonView.isMine)
    {
        Vector2 playerMovement = rb2D.position + velocity * Time.deltaTime;
        rb2D.MovePosition(playerMovement);          
    }
    if (photonView.isMine)
    {
        Vector2 playerMovement = rb2D.position + velocity * Time.deltaTime;      
        rb2D.MovePosition(playerMovement);
    }
}
