pygame系列_draw游戏画图
说到画图，pygame提供了一些很有用的方法进行draw画图。
‘‘‘pygame.draw.rect - draw a rectangle shape draw a rectangle shapepygame.draw.polygon - draw a shape with any number of sides draw a shape with any number of sidespygame.draw.circle - draw a circle around a point draw a circle around a pointpygame.draw.ellipse - draw a round shape inside a rectangle draw a round shape inside a rectanglepygame.draw.arc - draw a partial section of an ellipse draw a partial section of an ellipsepygame.draw.line - draw a straight line segment draw a straight line segmentpygame.draw.lines - draw multiple contiguous line segments draw multiple contiguous line segmentspygame.draw.aaline - draw fine antialiased lines draw fine antialiased linespygame.draw.aalines - pygame.draw.aalines(Surface, color, closed, pointlist, blend=1): return Rect‘‘‘
1 pygame.draw.rect #画一个矩形
下面是我做的demo
有鼠标在窗口中点击的时候，系统会自动画出一个矩形，按键盘任意键，清屏

代码部分：

1 #pygame draw 2 3 import pygame 4 from pygame.locals import * 5 from sys import exit 6 from random import * 7 8 __author__ = {‘name‘ : ‘Hongten‘, 9 ‘mail‘ : ‘hongtenzone@foxmail.com‘,10 ‘blog‘ : ‘http://www.cnblogs.com/hongten‘,11 ‘Version‘ : ‘1.0‘}12 13 pygame.init()14 15 SCREEN_DEFAULT_SIZE = (500, 500)16 SCREEN_DEFAULT_COLOR = (0, 0 ,0)17 18 screen = pygame.display.set_mode(SCREEN_DEFAULT_SIZE, 0, 32)19 screen.fill(SCREEN_DEFAULT_COLOR)20 21 while 1:22 for event in pygame.event.get():23 if event.type == QUIT:24 exit()25 elif event.type == KEYDOWN:26 screen.fill(SCREEN_DEFAULT_COLOR)27 elif event.type == MOUSEBUTTONDOWN:28 rect_color = (randint(0, 255), randint(0, 255), randint(0, 255))29 rect_pos = (randint(0, 500), randint(0, 500))30 rect_pos_end = (500 - randint(rect_pos[0], 500), 500 - randint(rect_pos[1], 500))31 pygame.draw.rect(screen, rect_color, Rect(rect_pos, rect_pos_end))32 pygame.display.update()1 pygame.draw.circle #画圆
demo：
当鼠标在窗口中移动的时候，单击鼠标，即可在窗口中产生一个随机圆，按下键盘任意键，清屏

demo：
鼠标在窗口中移动的时候，总是有一些线和鼠标汇聚，当鼠标被点击的时候，就会记录下此时的形状
按下键盘任意键，清屏
当然你也可以取消这个功能：
1 RECORD = False #取消记录鼠标轨迹
