我在游戏开发中使用pygame与python进行dable，我只是碰到了一堵砖墙。当我的一个实体尝试使用Vector2乘法移动时，我得到“致命的Python错误:( pygame parachute）Segmentation Fault”。
错误的直接代码是：
# destination and location are Vector2, and the difference is a Vector2
vec_to_destination = self.destination - self.location
distance_to_destination = vec_to_destination.length()
# normalize() returns a Vector2
heading = vec_to_destination.normalize()
# time_passed is a float and speed is an int
travel_distance = min(distance_to_destination, time_passed * self.speed)
# location is a Vector2 as well.
self.location += travel_distance * heading
# The previous line is where the Segmentation fault occurs.
# The equation looks like this with values filled in:
# Vector2(747, 183) += 6.435 * Vector2(-0.882763, 0.469818)
以下内容也可能有所帮助。您可以通过在python intepreter（Python 2.7和pygame 1.9.2pre）中键入以下内容来重现我遇到的问题：
import pygame
from pygame.math import *
v = Vector2(747, 183)
v2 = 6.435 * Vector2(-0.882763, 0.469818)
v += v2
v
