Pygame series _ draw game drawing

Speaking of drawing, pygame provides some useful methods.DrawDrawing.

‘‘‘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 # Draw a rectangle

Below is my demo

When you click in a window, the system will automatically draw a rectangle, press any key on the keyboard, clear the screen

1 pygame. Draw. Circle # Circle

Demo:

When the mouse moves in the window, click the mouse to generate a random circle in the window, press any key on the keyboard, clear the screen

1 pygame. Draw. Line # Draw line

Demo:

When the mouse moves in the window, there are always some lines and mouse convergence. When the mouse is clicked, it will record the shape at this time.

Press any key on the keyboard to clear the screen

You can also cancel this function:

1 record = false # cancel recording the mouse track
