在Unity中将消息从一个程序发送到另一个程序 [英] Send message from one program to another in Unity

问题描述

我在装有Windows操作系统的同一台计算机上运行两个不同的可执行文件.两者都是在Unity中构建的.我想在不使用网络的情况下将消息从一个发送到另一个 .

I have two different executable files running on same computer which has Windows OS. Both of them are build in Unity. I want to send message from one to other without using network.

如何将消息从exe程序发送到Unity中的另一个exe程序?

How do you send message from an exe program to another exe program in Unity?

使用integrated Mono/.net functionality或其他方式可能吗?

Is this possible with integrated Mono/.net functionality or something else?

推荐答案

您可以使用命名管道，该管道使用共享内存与同一计算机上的另一个应用程序进行通信.

You can use Named Pipes which uses shared memory to communicate with another application on the-same machine.

转到文件-> 构建设置... 选择 PC，Mac& Linux独立版，然后单击播放器设置... .现在，将 Api兼容级别更改为 .NET 2.0 .

Go to File --> Build Settings... select PC, Mac & Linux Standalone then click on Player Settings.... Now, change Api Compatibility Level to .NET 2.0.

关闭并重新打开Visual Studio.现在，您可以导入using System.IO.Pipes;并可以使用NamedPipeServerStream和NamedPipeClientStream.

Close and re-open Visual Studio. Now, you can import using System.IO.Pipes; and be able to use NamedPipeServerStream and NamedPipeClientStream.

下面是一个非常简化的服务器和客户端.您必须在Thread中执行此操作，并且还应处理异常.

Below is a very simplified server and client. You must do that in a Thread and should also handle exception.

如果您不想使用Thread，则还有一个异步参数(PipeOptions.Asynchronous)使其成为非阻塞运算符.从那里开始，事情变得复杂了，您必须在MS doc上寻找一些例子.

If you don't want to use Thread, there is also asynchronous parameter (PipeOptions.Asynchronous) that makes it a non blocking operator. It gets complicated from there and you have to look for some examples for that on MS doc.

简单服务器:

//Create Server Instance
NamedPipeServerStream server = new NamedPipeServerStream("MyCOMApp", PipeDirection.InOut, 1);
//Wait for a client to connect
server.WaitForConnection();
//Created stream for reading and writing
StreamString serverStream = new StreamString(server);
//Send Message to Client
serverStream.WriteString("Hello From Server");
//Read from Client
string dataFromClient = serverStream.ReadString();
UnityEngine.Debug.Log("Received from Client: " + dataFromClient);
//Close Connection
server.Close();

简单客户端:

//Create Client Instance
NamedPipeClientStream client = new NamedPipeClientStream(".", "MyCOMApp",
               PipeDirection.InOut, PipeOptions.None,
               TokenImpersonationLevel.Impersonation);

//Connect to server
client.Connect();
//Created stream for reading and writing
StreamString clientStream = new StreamString(client);
//Read from Server
string dataFromServer = clientStream.ReadString();
UnityEngine.Debug.Log("Received from Server: " + dataFromServer);
//Send Message to Server
clientStream.WriteString("Bye from client");
//Close client
client.Close();

来自StreamString类"rel =" noreferrer> MS Doc :

The StreamString class from MS Doc:

public class StreamString
{
    private Stream ioStream;
    private UnicodeEncoding streamEncoding;

    public StreamString(Stream ioStream)
    {
        this.ioStream = ioStream;
        streamEncoding = new UnicodeEncoding();
    }

    public string ReadString()
    {
        int len = 0;

        len = ioStream.ReadByte() * 256;
        len += ioStream.ReadByte();
        byte[] inBuffer = new byte[len];
        ioStream.Read(inBuffer, 0, len);

        return streamEncoding.GetString(inBuffer);
    }

    public int WriteString(string outString)
    {
        byte[] outBuffer = streamEncoding.GetBytes(outString);
        int len = outBuffer.Length;
        if (len > UInt16.MaxValue)
        {
            len = (int)UInt16.MaxValue;
        }
        ioStream.WriteByte((byte)(len / 256));
        ioStream.WriteByte((byte)(len & 255));
        ioStream.Write(outBuffer, 0, len);
        ioStream.Flush();

        return outBuffer.Length + 2;
    }
}
