Today we will continue with our draw’s class in Pygame and in this article we will draw a Polygon object with the pygame.draw.polygon method. This polygon method will take in a few arguments. 1) The screen surface 2) The color of the Polygon 3) An array of tuples contain the x, y coordinate 4) An optional width value if stated then the pygame.draw.polygon method will draw a hollow Polygon object or else the Polygon will be filled with solid color.
In the following script, after you have clicked on any 5 locations on the screen then the pygame.draw.polygon method will start to draw Polygon on the surface of that screen!
import pygame from pygame.locals import * from sys import exit pygame.init() screen = pygame.display.set_mode((640, 480), 0, 32) cooordinate =  while True: for event in pygame.event.get(): if event.type == QUIT: exit() if event.type == MOUSEBUTTONDOWN: #if mouse click then coordinate array will append x,y tuple cooordinate.append(event.pos) screen.fill((255,255,255)) screen.lock() if len(cooordinate) >= 5: pygame.draw.polygon(screen, (255,255,100), cooordinate, 3) screen.unlock() pygame.display.update()
Click on more positions on the screen and the shape will now change accordingly.
