Question

我正在创建一个小型在线多人游戏。我做了一些步骤。我配置了播放器预制件，我设法在场景中实例化一个对象，这要归功于：

[Command]
void Cmdbars()
{
    GameObject bar = Instantiate(barH, GameObject.Find("pos1").GetComponent<Transform>().transform.position, Quaternion.identity) as GameObject;

    NetworkServer.Spawn(bar);
}

现在我希望如果我们点击这个对象，它的精灵就会改变。因为我使用这种方法：

[Command]
void Cmdclick()
{
    if (Input.GetMouseButtonDown(0))
    {
        Vector2 origin = new Vector2(
                      Camera.main.ScreenToWorldPoint(Input.mousePosition).x,
                      Camera.main.ScreenToWorldPoint(Input.mousePosition).y);

        RaycastHit2D hit = Physics2D.Raycast(origin, Vector2.zero, 0f);


        if (hit && hit.transform.gameObject.tag.Equals("Untagged"))
        {
            hit.transform.gameObject.GetComponent<SpriteRenderer>().sprite = blueBarre.GetComponent<SpriteRenderer>().sprite;
            hit.transform.gameObject.tag = "ok";
        }
    }
}

问题是精灵只在本地改变，而不是在所有玩家中改变。

如果您想在所有客户端上执行代码，您将使用＆＃34; Rpc＆＃34;具有ClientRpc属性的方法。

例如，在您的情况下，它必须是这样的：

private void OnClick()
{
    Vector2 origin = new Vector2(
                  Camera.main.ScreenToWorldPoint(Input.mousePosition).x,
                  Camera.main.ScreenToWorldPoint(Input.mousePosition).y);

    CmdOnClick(origin.x, origin.y);        
}

//this code will be executed on host only, but can be called from any client
[Command(channel = 0)]
private void CmdClickHandling(float x, float y)
{
    RpcClick(x, y);
}

//this code will be executed on all clients
[ClientRpc(channel = 0)]
private void RpcClickHandling(float x, float y)
{
    //quit if network behaviour not local for preventing executing code for all network behaviours
    if (!isLocalPlayer)
    {
        return;
    }

    Vector2 osrigin = new Vector2(x, y);
    RaycastHit2D hit = Physics2D.Raycast(origin, Vector2.zero, 0f);

    if (hit && hit.transform.gameObject.tag.Equals("Untagged"))
    {

        hit.transform.gameObject.GetComponent<SpriteRenderer>().sprite = blueBarre.GetComponent<SpriteRenderer>().sprite;
        hit.transform.gameObject.tag = "ok";
    }
}
