如何在pygame/pygame 0中添加包装

Question

如果可以的话，我希望包装是我已经拥有的代码的附加组件，因为我知道这段代码可以无缝地从一侧平滑地运行到另一侧。基本上，我的代码允许从底部到顶部和从右侧到左侧包装，但不是从左侧到右侧和顶部到底部。我试过几件事情的我似乎已经和所有代码我已经影响或不工作。下面是代码:

if player.left > WIDTH: #if player hits right side of screen it takes the player to the left
player.right = 0
elif player.top > HEIGHT: #if player hits bottom it goes to top
player.bottom = 0

感谢所有的帮助!

Answer 1

您需要为这些情况添加条件:

if player.left > WIDTH:
player.right = 0
elif player.right < 0:  # if the player leaves to the left
player.left = WIDTH
elif player.top > HEIGHT:
player.bottom = 0
elif player.bottom < 0:  # if the player leaves to the right
player.top = HEIGHT

Answer 2

使用%(模)运算符。%运算符计算除法的余数:

player.centerx %= WIDTH 
player.centery %= HEIGHT
