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 shape pygame.draw.polygon - draw a shape with any number of sides draw a shape with any number of sides pygame.draw.circle - draw a circle around a point draw a circle around a point pygame.draw.ellipse - draw a round shape inside a rectangle draw a round shape inside a rectangle pygame.draw.arc - draw a partial section of an ellipse draw a partial section of an ellipse pygame.draw.line - draw a straight line segment draw a straight line segment pygame.draw.lines - draw multiple contiguous line segments draw multiple contiguous line segments pygame.draw.aaline - draw fine antialiased lines draw fine antialiased lines pygame.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

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

1 pygame.draw.line #画线
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
