PyPoint函数未按预期工作

Question

我正在用Python的PyGame编写一个双人坦克游戏，已经完成了大部分。为了给我的工作提供一些背景知识，这个游戏包括两辆坦克，它们可以互相发射炮弹，一旦一辆被击中，另一个玩家就得到一分。这个过程一直持续到一个玩家达到10分，他们被宣布为赢家，游戏和计时器重置。你知道吗

我的问题出现了，现在我已经画了一个迷宫的屏幕，以补充游戏，并添加一些更具创造性。我遇到了一个基本问题。Pygame.collidepoint没有按预期运行。我打算这样做，每次子弹从任何一个坦克击中一个迷宫墙，它应该消失，因为墙壁是注定无法穿透。然而，函数是任意选择子弹是否在接触时消失-我希望它是-或继续通过-我不希望它。有人知道为什么会这样吗？我开始假设这与.collidepoint对坐标的解释有关，我对此进行了测试，但没有成功。有没有更好的方法或功能来处理这个问题？如果有人能告诉我问题是否在我认为的地方，并告诉我如何/给我一小部分调整后的代码来解决它，那将不胜感激。我的整个代码相当长，所以我只包含了我认为必要的代码，以提供有关我正在做什么的足够信息。你知道吗

但是，我仍然会明确强调我遇到的问题，即用围绕代码部分的注释生成的大型显式块。如果一些更多的代码是需要的上下文，请让我知道，我可以提供它。你知道吗

Answer 1

答案是子弹的速度，因为它太快了，程序无法捕捉到它的滴答声，这基本上允许子弹穿过迷宫墙。你知道吗

可以将时钟调整为每秒60帧，如下所示：

clock.tick(60)

然后在射弹类，或任何一个确定子弹速度的地方，必须调整到时钟频率。你知道吗

如果你的速度是8，显示的时钟频率是30，那么把时钟频率调整到60，速度的一半，甚至是你想要的速度的比率。就我而言：

def __init__(self,x, y, radius, color, direction): 
    #ESTABLISH ALL DIMENSIONS
    self.x = x
    self.y = y
    self.radius = radius
    self.color = color
    self.direction = direction
    self.vel = 5 #if it was previously 8 with a clock tick of 30.

程序应该能够在子弹穿过墙壁之前抓住它的滴答声并阻止它。子弹在屏幕上移动的相对速度应该保持不变——记住也要相应地调整其他移动物体的速度，比如精灵。你知道吗
