方法二：画个直径为1的圆
importpygame,sys
pygame.init()
screen=pygame.display.set_caption('helloworld!')
screen=pygame.display.set_mode([640,480])
screen.fill([255,255,255])
pygame.draw.circle(screen,[0,0,0],[150,200],1,1)
pygame.display.flip()
whileTrue:
foreventinpygame.event.get():
ifevent.type==pygame.QUIT:
sys.exit()
importpygame,sys
pygame.init()
screen=pygame.display.set_caption('helloworld!')
screen=pygame.display.set_mode([640,480])
screen.fill([255,255,255])
screen.set_at([150,150],[255,0,0])#将150，150改为红色。
pygame.display.flip()
whileTrue:
foreventinpygame.event.get():
ifevent.type==pygame.QUIT:
sys.exit()
2、连接多个点形成线
pygame.draw.lines()方法可以将多个点连接成为线。该方法有5个参数：surface表面、颜色、闭合线或者非闭合线（如果闭合为True,否则为False），点的列表，线宽。pygame.draw.lines(surface,[color],False/True，plotpoints,1)。下面的例子画出了一条马路，具体如下：
importpygame,sys deflineleft():#画马路左边界 plotpoints=[] forxinrange(0,640): y=-5*x+1000 plotpoints.append([x,y]) pygame.draw.lines(screen,[0,0,0],False,plotpoints,5) pygame.display.flip() deflineright():#画马路右边界 plotpoints=[] forxinrange(0,640): y=5*x-2000 plotpoints.append([x,y]) pygame.draw.lines(screen,[0,0,0],False,plotpoints,5) pygame.display.flip() deflinemiddle():#画马路中间虚线 plotpoints=[] x=300 foryinrange(0,480,20): plotpoints.append([x,y]) iflen(plotpoints)==2: pygame.draw.lines(screen,[0,0,0],False,plotpoints,5) plotpoints=[] pygame.display.flip()
pygame.init() screen=pygame.display.set_caption('helloworld!') screen=pygame.display.set_mode([640,480]) screen.fill([255,255,255]) lineleft() lineright() linemiddle() whileTrue: foreventinpygame.event.get(): ifevent.type==pygame.QUIT: sys.exit()
