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)
