我有一个小问题,在搅拌机游戏引擎中有一个多线程 python 脚本。它工作正常,但是当我停止游戏时,它会引发一些异常并且有时会崩溃。

from bge import logic
import time
from threading import Thread

def init():

    if not hasattr(logic, 'init'):
        logic.init = 0
        logic.thread = new()
        logic.thread.start()

    logic.thread.restart()

class new(Thread):
    def __init__(self):
        self.Thread = Thread
        self.Thread.__init__(self)
    def run(self):
        number = 0
        while 1:
            number += 1
            print(number)
            try:
                main()
                time.sleep(0.1)
            except:
                break

    def restart(self):
        self.Thread.__init__(self)

def main(): #this part isn't important now ...
    cam = bge.logic.getCurrentScene().active_camera
    obj = bge.logic.getCurrentController().owner
    obj.worldPosition.x = cam.worldPosition.x
    obj.worldPosition.y = cam.worldPosition.y

控制台写道:

Unhandled exception in thread started by <bound method new._bootstrap of <new(Th
read-80, initial)>>
Traceback (most recent call last):
  File "C:\Program Files (x86)\Blender Foundation\Blender\2.64\python\lib\thread
ing.py", line 709, in _bootstrap
    self._bootstrap_inner()
  File "C:\Program Files (x86)\Blender Foundation\Blender\2.64\python\lib\thread
ing.py", line 784, in _bootstrap_inner
    with _active_limbo_lock:
AttributeError: __exit__

如果有人能找出问题所在,我会很高兴。谢谢

这是Blender 中 Python 脚本的一个众所周知的限制

问题是 Blender 在你的线程之前拆掉了 Python。您可以尝试做的是以某种方式注册 Blender(或您的游戏)正在退出,通知您的线程,并join从主线程通知它。
