我对python和模块pygame相当陌生。我最近还开始了一个小项目的工作，游戏的目的是，如果一个圆圈碰到了"玩家"(正方形(，那么游戏就会结束或出现一条消息，说你放松了(仍在努力解决点击框问题，所以仍在考虑之后该怎么办(。我遇到的问题是，我很难创建一种检测命中框碰撞的方法，每次我试图测试命中框是否碰撞时，它都不会起作用，所以如果有人能告诉我如何创建类和命中框，另一种方法，甚至如何修复我的代码，使其不会与播放器类碰撞。谢谢你的任何帮助，我可能会得到。
这是代码(如果我在试图找到解决方案时不断删除和添加内容，我会感到非常抱歉，如果我做了不恰当的事情，我也会感到抱歉，这是我的第一个问题(。

通常，我建议使用pygame.sprite.Sprite和pygame.sprite.Group，但我将向您展示一个更接近当前代码的解决方案。
创建一个Ball类，该类可以移动和绘制球对象。该类具有类型为pygame.Rect的.rect属性，而不是属性.x和.y，并且也可以用于"hitbox">
矩形在实例方法move():中更新
class Ball:
def __init__(self):
x = random.randrange(ball_size, width - ball_size)
y = random.randrange(ball_size, height - ball_size)
self.change_x, self.change_y = 0, 0
while self.change_x == 0 and self.change_y == 0:
self.change_x = random.randrange(-2, 3)
self.change_y = random.randrange(-2, 3)
self.rect = pygame.Rect(x-ball_size, y-ball_size, ball_size*2, ball_size*2)
def move(self):
self.rect = self.rect.move(self.change_x, self.change_y)
if self.rect.right >= height or self.rect.left < 0:
self.change_x *= -1
if self.rect.bottom >= width or self.rect.top <= 0:
self.change_y *= -1
def draw(self, surface):
pygame.draw.circle(surface, white, self.rect.center, ball_size)

在主应用程序循环中，球可以在for-循环中移动和绘制，碰撞测试可以通过.colliderect():进行
hits = 0
running = True
while running:
# [...]
for ball in ball_list:
if ball.rect.colliderect(rect):
hits += 1
print("hit " + str(hits))
# [...]
for ball in ball_list:
ball.move()
screen.fill(black)
for ball in ball_list:
ball.draw(screen)
Rectangle = pygame.draw.rect(screen, color, rect)
pygame.display.flip()
clock.tick(30)
