def update(self):
# Get the current mouse position. This returns the position
# as a list of two numbers
pos = pygame.mouse.get_pos()
# Fetch the x and y out of the list,
# just like we'd fetch letters out of a string.
# Set the player object to the mouse location
self.circ.x=pos[0]
self.circ.y=pos[1]
初始化 Pygame
就在 self.circ.x=pos[0] 所在的地方似乎有一个 unident/indentation 错误,我是 python 新手,想知道出了什么问题?
