我正在创建2D游戏，我的代码遇到了一些问题。首先，我的玩家不能同时发射子弹。另外，它们是否是在我的两个玩家和屏幕上的矩形之间创建边界的更简单的方法或函数，还是我只需要对矩形外部的点使用pyagame.Rect.collidepoint（），以及与矩形碰撞我会说：
if keystate[pygame.K_w] and not pygame.Rect.collidepoint():
self.y_change = -5

colliderect（）函数可以简化玩家之间的碰撞。
if keystate[pygame.K_s] and not pygame.Rect.collidepoint(self.rect, player2.rect.x + person2_width/2, player2.rect.y) \
and not pygame.Rect.collidepoint(self.rect, player2.rect.x + person2_width/4, player2.rect.y) \
and not pygame.Rect.collidepoint(self.rect, player2.rect.x + person2_width - 10, player2.rect.y):
可以简化为
if keystate[pygame.K_s] and not pygame.Rect.colliderect(self.rect, player2.rect):
我将这些矩形放入列表中，然后使用colliderect（）函数在每个函数中对其进行循环检查。
thing_starts.append((display_width/2, display_height/2))
thing_starts.append((display_width / 2 - thing_width, display_height / 2 - thing_height))
...
blocks = []
for thing_start in thing_starts:
blocks.append(pygame.draw.rect(gameDisplay, black, (thing_start[0], thing_start[1], thing_width, thing_height)))
...
for block in blocks:
if pygame.Rect.colliderect(block, bullet):
bullet.kill()
（编辑：请注意，列表理解可以进一步简化操作，但这是高级操作。不过，如果您提出要求，我将向您展示。）
