pygame - KEYDOWN事件 - 线条未更新位置

Question

我正在制作一个两人对战的游戏，游戏的样子大概是这样的：
游戏图片
在这个游戏中，玩家控制的射手（绿色和蓝色）可以互相发射子弹。
如果子弹
1. 碰到墙壁（灰色），它就会被销毁。
2. 打到射手，射手就会失去生命值。
这个游戏是回合制的，直到有一个玩家的生命值降到0时就结束。

我的问题
1. 我的射手的枪管没有更新或旋转。
2. 有没有更好的方法来检测按下了哪个键。
* 射手、子弹、墙壁都是类

（如果有任何有用的函数没有提到，请评论）

def draw_all(bullist,shooters,wall,surface):

        if c != C and c != [95,392]:
            print c
            C = c
        pygame.draw.line(surface,self.color2,self.rect.center,c,3)


## the other funcs or classes not needed

# globals
turn = 1
C = []
# pygame
(width, height) = (640, 480)
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption('Shooter')
clock = pygame.time.Clock()
# game actors
shooters = []
bullets = []
p1 = Shooter((400,400),(30,-15),(255,0,0),0,0)
p2 = Shooter((100,400),(30,-15),(0,255,0),0,0)
shooters.extend([p1, p2])
wall = Wall(100)

running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
            pygame.quit()
            break
        else: event_handle(event,turn)
    if not running:
        break
    screen.fill((0,0,0))
    # Game draw logic + Game logic

    draw_all(bullets,shooters,wall,screen)
    pygame.display.flip()
    clock.tick(40)

我哪里做错了？
