python - 有敌人射击玩家问题吗？游戏

Question

我试图让我的敌人射击我的玩家，但由于某种原因，子弹没有显示，也没有向玩家射击我什至不知道为什么，我什至在我的 window 上画了子弹 VIDEO

bulls = []
runninggame = True
while runninggame:
    clock.tick(FPS)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            runninggame = False

    for bull in bulls:
        if bull.x < 500 and bull.x > 0:
            bull.x += bull.vel  # Moves the bullet by its vel
        else:
            for enemys in enemying:
                if playerman.x - 100 <= enemys.x <= playerman.x + 100 and playerman.y - 100 <= enemys.y <= playerman.y + 100:
                    bulls.pop(bulls.index(bull))
                    bulls.append(enemybullets(round(enemys.x+enemys.width//2), round(enemys.y + enemys.height//2), 6, (0,0,0), facing)) 

然后我在下面调用它

    for bull in bulls:
        bull.draw(window)

我的敌人射弹类

# enemys bullets
class enemybullets(object):
    def __init__(self,x,y,radius,color,facing):
        self.x = x
        self.y = y
        self.radius = radius
        self.color = color
        self.facing = facing
        self.vel = 8 * facing

    def draw(self,win):
        pygame.draw.circle(win, self.color, (self.x,self.y), self.radius)

Answer 1

这是我前一段时间在教程的帮助下制作的一个非常相似的游戏的代码。

我的第一个建议是尝试降低子弹的速度。这样您就可以确保不会遗漏屏幕上的任何内容。

接下来确保您正确更新屏幕内容。

如果不查看您的完整代码，很难给出全面的答案。我已将我的代码包含在此处，以便您可以引用并解决问题。

希望这对您有所帮助。
