如何修复“ BitStream已过时”

Question

BitStream在2018.3中已过时，而unity要求改为使用MultiPlayer或NetworkIdentity，但我无法在上述类中找到合适的功能。我试图替换类“ Bit Stream”，但它不起作用

void OnSerializeNetworkView(BitStream stream)
{
    Vector3 syncPosition = Vector3.zero;
    if (stream.isWriting)
    {
        syncPosition = GetComponent<Rigidbody2D>().position;
        stream.Serialize(ref syncPosition);

        syncPosition = GetComponent<Rigidbody2D>().velocity;
        stream.Serialize(ref syncVelocity);
    }
    else
    {
        stream.Serialize(ref syncPosition);
        stream.Serialize(ref syncVelocity);

        syncTime = 0f;
        syncDelay = Time.time - lastSynchronizationTime;
        lastSynchronizationTime = Time.time;

        syncEndPosition = syncPosition + syncVelocity * syncDelay;
        syncStartPosition = GetComponent<Rigidbody2D>().position;
    }
}

错误：
