从Unity运行Python脚本，以便在我的游戏中使用其输出(文本文件)

Question

我正在尝试从Unity（C＃脚本）运行Python脚本来使用其输出，这是我游戏中的文本文件，事实是，当我运行C＃脚本时在团结中，什么都没有发生（Python脚本单独起作用）。谁能告诉我我想念什么？谢谢。

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System.ComponentModel;
using System.Text;
using System.IO;
using UnityEngine.UI;
using System.Text.RegularExpressions;
using System.Diagnostics;
using System.Runtime.InteropServices;
public class PyCx : MonoBehaviour {
    public Text Message;
    public GameObject OpenPanel1 = null;
    // Use this for initialization
    void Start () {
        python ();
        read ();
        ShowMessage ();
    }
    public void python(){
        ProcessStartInfo pythonInfo = new ProcessStartInfo ();
        Process python;
        pythonInfo.FileName=@"C:UsersHPAppDataLocalProgramsPythonPython36-32python.exe";
        pythonInfo.Arguments=@"C:UsersHPDocumentsprojet1.pyw";
        pythonInfo.CreateNoWindow = false;
        pythonInfo.UseShellExecute = false;
        python = Process.Start (pythonInfo);
        python.WaitForExit ();
        python.Close ();
    }
    public void read(){
        using (var reader = new StreamReader ("C://Users//HP//Documents//result.txt")) {
            string line = reader.ReadToEnd ();
            Message.text = (line);
        }
    }
    public void ShowMessage(){
        OpenPanel1.SetActive (true);
        Message.IsActive ();
    }
    // Update is called once per frame
    void Update () {
    }
}

Answer 1

，而不是使用在受控开发环境之外可能不可靠的过程（您不知道您的用户是否会安装Python和哪个版本），您可以尝试直接运行Python在使用Ironpython的代码中，Ironpython是CLR的Python解释器，因此甚至不需要安装Python即可执行您的脚本。

要使用它，您需要从http://ironpython.net/download/

下载编译的二进制文件

然后在您的资源文件夹中复制所有必需的程序集：

• ironpython.dll
• ironpython.modules.dll
• microsoft.scripting.core.dll
• microsoft.scripting.dll
• microsoft.scripting.debugging.dll
• microsoft.scripting.extensionattribute.dll
• microsoft.dynamic.dll

然后，您可以访问Python引擎，您可以按以下方式初始化它：

PythonEngine engine = new PythonEngine();  
engine.LoadAssembly(Assembly.GetAssembly(typeof(GameObject)));         
engine.ExecuteFile("Project1.py");

您可以在此处查看更多信息：http：//ironpython.net/documentation/

Answer 2

• 使用链接Unity Python 0.4.1
下载Unity Python软件包
• 然后，转到编辑>项目设置>播放器>其他设置>配置和更改脚本运行时版本为"实验（.net 4.6等效）。

假设您有一个小的代码片段。

class Test():
    def __init__(self, name):
        self.name = name
    def display(self):
        return "Hi, " + self.name

您可以从c＃使用

使用它

using System.Collections;
using System.Collections.Generic;
using IronPython.Hosting;
using UnityEngine;
public class PythonInterfacer : MonoBehaviour {
 void Start () {
        var engine = Python.CreateEngine();
        ICollection<string> searchPaths = engine.GetSearchPaths();
        //Path to the folder of greeter.py
        searchPaths.Add(@"C:UsersCodemakerDocumentsPythonDemoAssetsScriptsPython");
        //Path to the Python standard library
        searchPaths.Add(@"C:UsersCodemakerDocumentsPythonDemoAssetsPluginsLib");
        engine.SetSearchPaths(searchPaths);
        dynamic py = engine.ExecuteFile(@"C:UsersCodemakerDocumentsPythonDemoAssetsScriptsPythontest.py");
        dynamic obj = py.Test("Codemaker");
        Debug.Log(obj.display());
    }
}

这是我的工作。希望这会有所帮助。

var psi = new ProcessStartInfo();
// point to python virtual env
psi.FileName = @"C:UserssomeoneDocumentsgit-reposPythonVenvsvenvScriptspython.exe";
// Provide arguments
var script = @"AssetsScriptssomecoolpythonstuffcool.py";
var vidFileIn = "111";
var inputPath = @"Assetsinput";
var outputPath = @"Assetsoutput";
psi.Arguments = string.Format(""{0}" -v "{1}" -i "{2}" -o "{3}"", 
                               script, vidFileIn, inputPath, outputPath);
// Process configuration
psi.UseShellExecute = false;
psi.CreateNoWindow = false;
psi.RedirectStandardOutput = true;
psi.RedirectStandardError = true;
// Execute process and get output
var errors = "nothing";
var results = "nothing";
using (var process = Process.Start(psi))
{
    errors = process.StandardError.ReadToEnd();
    results = process.StandardOutput.ReadToEnd();
}
// grab errors and display them in UI
StringBuilder buffy = new StringBuilder();
buffy.Append("ERRORS:n");
buffy.Append(errors);
buffy.Append("nn");
buffy.Append("Results:n");
buffy.Append(results);
// ui text object
responseText.Text = buffy.ToString();

您可以尝试以下GitHub存储库代码。您将获得一个从文件中使用python代码的基本想法
