在上一节中，我们创建了一个随机组合的图形组, 如何绘制呢?
（1）我们有图形的行列位置, 有形状, 有颜色, 首先， 我们需要一个 函数, 能够根据这些信息来绘制一个图形:
def drawIcon(displaysurf, shape, color, boxx, boxy):
# 根据位置，形状，颜色，绘制一个图形
quarter = int(BOXSIZE * 0.25)
half = int(BOXSIZE * 0.5)
left, top = leftTopCoordsOfBox(boxx, boxy)
if shape == DONUT:
pygame.draw.circle(displaysurf, color, (left+half, top+half), half-5)
pygame.draw.circle(displaysurf, BGCOLOR, (left+half, top+half), quarter-5)
elif shape == DIAMOND:
pygame.draw.polygon(displaysurf, color, ((left+half, top),
(left+BOXSIZE-1, top+half),
(left+half, top+BOXSIZE-1),
(left, top+half)))
elif shape == SQUARE:
pygame.draw.rect(displaysurf, color, (left+quarter, top+quarter,
BOXSIZE-half, BOXSIZE-half))
elif shape == LINES:
for i in range(0, BOXSIZE, 4):
pygame.draw.line(displaysurf, color, (left, top+i), (left + i, top))
pygame.draw.line(displaysurf, color, (left+i, top+BOXSIZE-1),
(left+BOXSIZE-1, top+i))
elif shape == OVAL:
pygame.draw.ellipse(displaysurf, color, (left, top+quarter, BOXSIZE, half))
（2）然后，再创建一个函数，来绘制所有的随机图形的组合
def drawBoard(displaysurf, board):
# 绘制所有的图形组
for boxx in range(BOARD_WIDTH):
for boxy in range(BOARD_HEIGHT):
shape, color = getShapeAndColor(board, boxx, boxy)
drawIcon(displaysurf, shape, color, boxx, boxy)
（3）在main函数中测试一下功能：
def main():
pygame.init()
fpsclock = pygame.time.Clock()
displaysurf = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
pygame.display.set_caption("Memory Game")
displaysurf.fill(BGCOLOR)
# 创建图形组合
board = getRandomizedBoard()
while True:
displaysurf.fill(BGCOLOR)
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
# 绘制图形组合
drawBoard(displaysurf, board
pygame.display.update()
fpsclock.tick(FPS)
if __name__ == '__main__':
main()
结果显示如下：
