翻译 - Unity3D 中的 IronPython

Question

我想用IronPython作为Unity的外部语言脚本。IronPython执行加载所需的DLL放在Assets\Plugins。然而，当我运行脚本的时候出现了如下错误：

PythonImportErrorException: No module named UnityEngine
IronPython.Modules.Builtin.__import__ (IronPython.Runtime.Calls.ICallerContext,string,object,object,object) <IL 0x0003b, 0x001cc>

脚本和UnityEngine.dll是在同一个文件夹里的。这个是脚本。

import clr
clr.LoadAssemblyFromFile("UnityEngine.dll")

import UnityEngine
from UnityEngine import *

Debug.Log("Hello World from Python!")

Answer from @Storm Kiernan:
Script from Unity:

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

In the python script (my pple.py and game.exe are placed in the same folder):

import UnityEngine
from UnityEngine import *

Debug.Log("Hello From IronPython!")

Edit #1

I should point out that the reason I got the error is that the runtime version was specified as 4.0, not 3.5 or lower.

Edit #2

If you need to access scripts from IronPython, you can also load the assembly via:

engine.LoadAssembly(Assembly.GetAssembly(typeof(MyPlayerScriptOrSomething)));

Then use it in the script:

import MyPlayerScriptOrSomething

Note that you don't need to load the assembly for every script, you only need to get the assembly once.

Edit #3

IronPython DLL should be placed in the Plugins folder under Assets, this is my setting.

Edit #4

Scripts can be placed anywhere that any program can access. For example, if you want to put apple.py" directly in C:, you can do it through the following methods:

engine.ExecuteFile(@"c:\apple.py");

Edit #5

The version I am using now is:
