为什么下面的 python while 循环永远不会中断？它是一个简单的机器人

Question

def turn():

x=0

while x==0:

    #the players X co-ordinate, and the players Y co-ordinate is set to 513,437 respectively

    player_x, player_y=513,437

    #It looks for the HP bar of the monster, and then notes down the location in terms of left, right, height in the variable target (or target2, whichever it detects.)

    target = pyautogui.locateOnScreen(os.path.expanduser(r'~\Desktop\wow bot\references\target.png'),

                                      region=(0, 0, 1024, 768), confidence=.7)

    target2 = pyautogui.locateOnScreen(os.path.expanduser(r'~\Desktop\wow bot\references\target2.png'),

                                       region=(0, 0, 1024, 768), confidence=.7)

    #this turns the target location into an X, and Y format. So the location of the mob gets turned into x and y position and stored in target_x and target_y

    if target is not None or target2 is not None:

        global targety

        global targetx

        target_point=pyautogui.center(target or target2)

        targetx,targety=target_point

    #distance a = square root of target_y minus players_y to the power of 2

    distance_a=math.sqrt((targety-player_y)**2)

    #distance h = square root of target_X minus player_x to the power of 2 plus target_y minus player_y to the power of 2

    distance_h=math.sqrt((targetx-player_x)**2+(targety-player_y)**2)

    #inverse tan of distance a divide by distance h

    radian=math.acos(distance_a/distance_h)

    #turns radian into degrees

    theta=(radian*180/math.pi)

    #displays output of the degrees

    print((theta))

    direction=player_x-targetx

    print(direction)

我不明白为什么上面的代码没有中断？它是一个简单的机器人，除了转向它面对目标之外什么都不做。我希望循环中断，以便之后我可以继续执行另一项任务。

您的循环只会在theta=25您的第一个if条件声明时中断，theta>=25而嵌套的 if 条件声明theta<=25then onlyx=1这是非常荒谬的，因此条件仅满足theta=25
