在上一節(jié)中巴元，我們創(chuàng)建了一個(gè)隨機(jī)組合的圖形組, 如何繪制呢?
（1）我們有圖形的行列位置, 有形狀, 有顏色, 首先论矾， 我們需要一個(gè) 函數(shù), 能夠根據(jù)這些信息來(lái)繪制一個(gè)圖形:
def drawIcon(displaysurf, shape, color, boxx, boxy):
# 根據(jù)位置，形狀沛简，顏色齐鲤，繪制一個(gè)圖形
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，再創(chuàng)建一個(gè)函數(shù)椒楣，來(lái)繪制所有的隨機(jī)圖形的組合
def drawBoard(displaysurf, board):
# 繪制所有的圖形組
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函數(shù)中測(cè)試一下功能：
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)
# 創(chuàng)建圖形組合
board = getRandomizedBoard()
while True:
displaysurf.fill(BGCOLOR)
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
# 繪制圖形組合
drawBoard(displaysurf, board
pygame.display.update()
fpsclock.tick(FPS)
if __name__ == '__main__':
main()
結(jié)果顯示如下：
