我有一个需要侦听服务器消息的客户端脚本。事情的服务器端似乎工作正常，但由于我对网络非常陌生，所以我仍然试图将事情整理在一起。我正在使用Unity的NetworkTransport API进行配置和连接。卡住的地方是如何正确创建我的客户端注册处理程序以从服务器接收传入消息类型。设置RegisterHandler的正确方法
从服务器上，我通过发送：
public void SendTexture(Texture2D tex, string type, int id, int strength, int hitpoints)
{
TextureMessage msg = new TextureMessage();
//Convert Texture2D to byte array
msg.Tex = tex.GetRawTextureData();
msg.Type = type;
msg.Id = id;
msg.Strength = strength;
msg.Hitpoints = hitpoints;
NetworkServer.SendToAll(MyMsgType.texture, msg);
}
但我不能确定如何构建事物的接收端在客户端上。我得到的最远的是这一点，但我已经破事：
public void setupRegisterHandler()
{
//Register to texture receive event
NetworkClient.RegisterHandler(MyMsgType.texture, OnTextureReceive);
}
public void OnTextureReceive(NetworkMessage netMsg)
{
TextureMessage msg = netMsg.ReadMessage<TextureMessage>();
string type = msg.Type;
Debug.Log("Type : " + type);
int id = msg.Id;
Debug.Log("ID : " + id);
int strength = msg.Strength;
Debug.Log("Strength : " + strength);
int hitpoints = msg.Hitpoints;
Debug.Log("Hit Points : " + hitpoints);
//Your Received Texture2D
Texture2D receivedtexture = new Texture2D(1280, 1024);
receivedtexture.LoadRawTextureData(msg.Tex);
receivedtexture.Apply();
}
从线NetworkClient.RegisterHandler(MyMsgType.texture, OnTextureReceive);，我发现了错误'Assets/Scripts/Client.cs(106,17): error CS0120: An object reference is required to access non-static member 'UnityEngine.Networking.NetworkClient.RegisterHandler(short, UnityEngine.Networking.NetworkMessageDelegate)'
如何设置我的setupRegisterHandler（）函数是否正确？近一个月来我一直在网络上苦苦挣扎，我感觉我好像很亲密！如果您需要它们，我还包括下面的完整脚本以供参考。谢谢！
