现在我想知道是否有人知道如何做碰撞，例如是玩家男孩接触到敌人的怪物则是绘制到屏幕的卫生下降。Thaks对你有所帮助！
Now I was wondering if anybody knows how to do collision, for example is the player boy is touching the enemy monster then the health which is draw to the screen goes down.Thaks for your help!
推荐答案
这是从我的回答对计算器进行一些修改之后做了另一个问题，code。
It is code from my answer to another question on stackoverflow with some modification made later.
我有碰撞检测在这里，但它并不理想。
I have collision detection here but it is not ideal.
查找 pygame.sprite.collide_rect（self.ball，self.player1）
它用矩形区域来检测碰撞
It use rectangle area to detect collision
更多冲突检测的 pygame的雪碧（矩形，圆形，具有屏蔽功能）
More collision detect functions on PyGame Sprite (rectangle, circle, with mask)
（移动PLAYER1（键：W / S）或player2（键：箭头上/下），使球发生碰撞）
(move player1 (keys: W/S) or player2 (keys: ARROWS UP/DOWN) to make collision with ball)
PS： 播放和球要求自.rect （ pygame.Rect（））与位置（ self.rect.x ， self.rect.y ），大小（自.rect.width ， self.rect.height ）以可与使用pygame.sprite.collide_rect（）。如果您使用 pygame的雪碧创建播放类（类播放器（pygame.sprite.Sprite）：）您不必创建 self.rect 因为雪碧已经有 self.rect - 但你还是要改变 self.rect.x 和 self.rect.y 当您移动播放器。
ps.: player and ball required self.rect (pygame.Rect()) with position (self.rect.x, self.rect.y) and size (self.rect.width, self.rect.height) to can be used with pygame.sprite.collide_rect(). If you use PyGame Sprite to create player class (class Player(pygame.sprite.Sprite):) you don't have to create self.rect because Sprite already has self.rect - but you still have to change self.rect.x and self.rect.y as you move player.
