Ironpython可以用于并行运行多个Python虚拟机实例吗？

Question

Inspired from the game GunTactyx , where you write programs controlling fighting robots. Guntactyx used the Small language, that later is called Pawn.

I am looking into using Python as the scripting language.

My concerns are:

1. Interfacing to C# The scripts should interface into C# through simple functions, doing stuff like scanning for enemies, rotating and firing. I guess each function should be delayed, so they would take x ms to return.

2. Bad programs. The system should be tolerant to infinite loops or crashes. I would like each virtual machine to be given X ticks to execute at a time.

3. Limited memory usage Scripts should not be allowed to use unlimited usage. I would like some sort of cap.

4. Probably alot of other problems

I would like to end up with something in this "pseudo" style.

robots = a list of robots

while(1)
   foreach robot in robots
      robot.tick()
   gameworld.update()

The answer to your subject question is yes , you can run multiple interpreters in parallel. Generally each script will run in its own ScriptScope , but you can also use isolated ScriptEngine s if necessary.

1. You can inject variables/functions into a script's scope before running it using scope.SetVariable .

2. Your best bet is to run the Python code on a separate thread and watch it; if it takes too long to return, interrupt the thread. _{(this is tricky to get right, but that's a different question)}

3. I'm not sure that can enforced easily. It may be possible if you run the scripts in a different AppDomain or process, but that's a lot of extra work for minimal gain.

4. Just ask!
