问题描述

有什么方法可以清除已被污渍覆盖的表面吗?

Is there any way to clear a surface from anything that has been blitted to it?

推荐答案

如果要使pygame Surface对象干净"，则擦除所有被涂抹过的图像，并在每次游戏循环中为其涂抹新图像并保持对等像素的Alpha值而不创建新的表面，您可以填充它，但是要使用纯色而不是纯色

If what you want is to make a pygame Surface object "clean", that is erase all images blited to it, to blit new images to it every game loop and keep the peer pixel alpha without creating a new surface, you can fill it, but instead of a solid color, use a transparent color

from pygame import Color, Surface
empty = Color(0,0,0,0) #The last 0 indicates 0 alpha, a transparent color
field = Surface((width, height), flags=SRCALPHA)

#Inside the game loop
field.fill(empty)
