Pygame - Drawing Shapes

---

Different shapes such as rectangle, circle, ellipse, polygon and line can be drawn on the game window by using functions in pygame.draw module −

draw a rectangle	rect(surface, color, rect)
draw a polygon	polygon(surface, color, points)
draw a circle	circle(surface, color, center, radius)
draw an ellipse	ellipse(surface, color, rect)
draw an elliptical arc	arc(surface, color, rect, start_angle, stop_angle)
draw a straight line	line(surface, color, start_pos, end_pos, width)

Example

Following example uses these functions to draw different shapes −

import pygame

pygame.init()
screen = pygame.display.set_mode((400, 300))
done = False
red = (255,0,0)
green = (0,255,0)
blue = (0,0,255)
white = (255,255,255)
while not done:
   for event in pygame.event.get():
      if event.type == pygame.QUIT:
         done = True
   pygame.draw.rect(screen, red, pygame.Rect(100, 30, 60, 60))
   pygame.draw.polygon(screen, blue, ((25,75),(76,125),(275,200),(350,25),(60,280)))
   pygame.draw.circle(screen, white, (180,180), 60)
   pygame.draw.line(screen, red, (10,200), (300,10), 4)
   pygame.draw.ellipse(screen, green, (250, 200, 130, 80)) 
   pygame.display.update()

Output

If an optional integer parameter is added to the functions, the shape will be drawn with specified color as outline color. Number corresponds to thickness of the outline and background color inside the shape.

pygame.draw.rect(screen, red, pygame.Rect(100, 30, 60, 60),1)
pygame.draw.circle(screen, white, (180,180), 60,2)
pygame.draw.ellipse(screen, green, (250, 200, 130, 80),5)
