Unity直接调用Python脚本

Windows and Ubuntu

Windows

Unity的工程直接调用 python脚本，然后输出相应的结果。

1 Unity 工程和脚本

新建一个工程，并添加脚本LoadPython.cs

using System.Collections;using System;using System.Collections.Generic;using UnityEngine;using System.Diagnostics; //需要添加这个名词空间，调用DataReceivedEventArg public class LoadPython : MonoBehaviour{string sArguments = @"UnityLoad.py";//这里是python的文件名字// Use this for initializationvoid Start(){RunPythonScript(sArguments, "-u");}// Update is called once per framevoid Update(){RunPythonScript(sArguments, "-u");}public static void RunPythonScript(string sArgName, string args = ""){Process p = new Process();//python脚本的路径string path = @"F:\pythonBuffer\" + sArgName;string sArguments = path;//(注意：用的话需要换成自己的)没有配环境变量的话，可以像我这样写python.exe的绝对路径//(用的话需要换成自己的)。如果配了，直接写"python.exe"即可p.StartInfo.FileName = @"python.exe";//p.StartInfo.FileName = @"C:\Program Files\Python35\python.exe";// sArguments为python脚本的路径 python值的传递路线strArr[]->teps->sigstr->sArguments //在python中用sys.argv[ ]使用该参数p.StartInfo.UseShellExecute = false;p.StartInfo.Arguments = sArguments; p.StartInfo.RedirectStandardOutput = true;p.StartInfo.RedirectStandardInput = true;p.StartInfo.RedirectStandardError = true;p.StartInfo.CreateNoWindow = true;p.Start();p.BeginOutputReadLine();p.OutputDataReceived += new DataReceivedEventHandler (Out_RecvData);Console.ReadLine();p.WaitForExit();}static void Out_RecvData(object sender, DataReceivedEventArgs e){if (!string.IsNullOrEmpty(e.Data)) {UnityEngine.Debug.Log (e.Data);}}}

2 新建python脚本 UnityLoad.py

# -*- coding: utf-8 -*-PoemName = "杜甫《江畔独步寻花·其六》"PoemTest = """黄四娘家花满蹊，千朵万朵压枝低。留连戏蝶时时舞，自在娇莺恰恰啼。"""print(PoemName)print(PoemTest)MottoEn = "A warm smile is the universal language of kindness."MottoCh = "温暖的微笑是表示善意的通用语言。"print(MottoEn)print(MottoCh)

3 运行unity调用

Ubuntu

1 Unity 工程和脚本

新建一个工程，并添加脚本RunPython.cs

using System.Collections;using System;using System.Collections.Generic;using UnityEngine;using System.Diagnostics; //需要添加这个名词空间，调用DataReceivedEventArg public class RunPython : MonoBehaviour{string sArguments = @"UnityPython.py";//这里是python的文件名字// Use this for initializationvoid Start(){RunPythonScript(sArguments, "-u");}// Update is called once per framevoid Update(){RunPythonScript(sArguments, "-u");}public static void RunPythonScript(string sArgName, string args = ""){Process p = new Process();//python脚本的路径//string path = @"F:\BUFFER\PycharmBuffer\" + sArgName; string path = @"/home/michael/BUFFER/PycharmBuffer/" + sArgName;string sArguments = path;//文件目录的查询参考 /moonlightpeng/article/details/116195087?spm=1001..3001.5501print("hello python");//(注意：用的话需要换成自己的)没有配环境变量的话，可以像我这样写python.exe的绝对路径//(用的话需要换成自己的)。如果配了，直接写"python.exe"即可p.StartInfo.FileName = @"/home/michael/.conda/envs/PVNet/bin/python";//注意Ubuntu系统pyhton后缀没有.exe//p.StartInfo.FileName = @"C:\Program Files\Python35\python.exe";// sArguments为python脚本的路径 python值的传递路线strArr[]->teps->sigstr->sArguments //在python中用sys.argv[ ]使用该参数p.StartInfo.UseShellExecute = false;p.StartInfo.Arguments = sArguments; p.StartInfo.RedirectStandardOutput = true;p.StartInfo.RedirectStandardInput = true;p.StartInfo.RedirectStandardError = true;p.StartInfo.CreateNoWindow = true;p.Start();p.BeginOutputReadLine();p.OutputDataReceived += new DataReceivedEventHandler (Out_RecvData);Console.ReadLine();p.WaitForExit();}static void Out_RecvData(object sender, DataReceivedEventArgs e){if (!string.IsNullOrEmpty(e.Data)) {UnityEngine.Debug.Log (e.Data);}}}

2 新建python脚本 UnityPython.py

# -*- coding: utf-8 -*-PoemName = "杜甫《客至》"PoemTest = """舍南舍北皆春水，但见群鸥日日来。花径不曾缘客扫，蓬门今始为君开。盘飧市远无兼味，樽酒家贫只旧醅。肯于邻翁相对饮，隔离呼取尽馀杯。"""print(PoemName)print(PoemTest)MottoEn = "If you can't fly then run, if you can't run then walk, if you can't walk then crawl" \"but whatever you do you have to keep moving forward."MottoCh = "如果不能飞，那就跑；如果跑不动，那就走；实在走不动了，那就爬。无论做什么，你都要勇往直前。"print(MottoEn)print(MottoCh)

3 运行unity调用

注意事项：加载的python脚本名要写对，如果写错了竟然不会报错，仔细一点。
