我正在制作一个涉及旋转链条部件的小游戏。我是 pygame 的新手,但这是开始。
#!/usr/bin/python
import pygame
def draw(square):
(x,y) = square
pygame.draw.rect(screen, black, (100+x*20,100+y*20,20,20), 1)
def rotate(chain, index, direction):
(pivotx, pivoty) = chain[index]
if (direction == 1):
newchain = chain[:index]+[(y-pivoty+pivotx, (x-pivotx)+pivoty) for (x,y) in chain[index:]]
else:
newchain = chain[:index]+[(y-pivoty+pivotx, -(x-pivotx)+pivoty) for (x,y) in chain[index:]]
if (set(chain) & set(newchain[index+1:]) == set()):
return newchain
else:
print "Collision!"
return chain
pygame.init()
size = [600, 600]
screen = pygame.display.set_mode(size)
white = (255,255,255)
black = (0,0,0)
n = 20
chain = [(i,0) for i in xrange(n)]
screen.fill(white)
for square in chain:
draw(square)
pygame.display.flip()
raw_input("Press Enter to continue...")
newchain = rotate(chain, 5, 1)
print chain
print newchain
screen.fill(white)
for square in newchain:
draw(square)
pygame.display.flip()
raw_input("Press Enter to continue...")
是否有可能使旋转看起来像动画一样流畅,而不是仅仅跳到pygame中的正确位置?
