Question

我做了一个简单的多人射击游戏，到目前为止一切都很好，除了所选择的武器没有显示enyone但主机例如如果我选择武器1（ak47）没有人可以看到除了服务器主机相同的对象为我的其他武器，我相信我需要使用NetworkServer.Spawn生成它们，但我不知道该怎么做。谢谢eny anwsers !!!

你正在调用一个Command，这就是为什么它只在服务器/主机上运行，命令是服务器代码，RPC是客户端代码，所以如果你想向你需要的每个人发送一些动作从服务器/主机调用RPC。

public class PlayerController : NetworkBehaviour
{
    [Command]
    void CmdSwitchtoAk()
    {
        RpcSwitchtoAk();
    }

    [ClientRpc]
    void RpcSwitchtoAk()
    {
        changeWeapon(1);
        CurrentWeaponstr = "Ak47";
    }
}

来自客户的呼叫命令
该命令在服务器上运行，然后使用RPC
服务器调用RPC
所有客户端都获得回调

参考：Unity Unet Manual

武器只对服务器主机
