Pygame Drawing a Rectangle

问题

Im making a game that requires knowing how to draw a rectangle in python 3.2.

I have checked lot of sources but none show exactly how to do it.

Thanks!

import pygame, sys
from pygame.locals import *

def main():
    pygame.init()

    DISPLAY=pygame.display.set_mode((500,400),0,32)

    WHITE=(255,255,255)
    BLUE=(0,0,255)

    DISPLAY.fill(WHITE)

    pygame.draw.rect(DISPLAY,BLUE,(200,150,100,50))

    while True:
        for event in pygame.event.get():
            if event.type==QUIT:
                pygame.quit()
                sys.exit()
        pygame.display.update()

main()

This creates a simple window 500 pixels by 400 pixels that is white. Within the window will be a blue rectangle. You need to use the pygame.draw.rect to go about this, and you add the DISPLAY constant to add it to the screen, the variable blue to make it blue (blue is a tuple that values which equate to blue in the RGB values and it's coordinates.

Look up pygame.org for more info

here's how:

import pygame
screen=pygame.display.set_mode([640, 480])
screen.fill([255, 255, 255])
red=255
blue=0
green=0
left=50
top=50
width=90
height=90
filled=0
pygame.draw.rect(screen, [red, blue, green], [left, top, width, height], filled)
pygame.display.flip()
running=True
while running:
    for event in pygame.event.get():
        if event.type==pygame.QUIT:
            running=False
pygame.quit()

Have you tried this:

PyGame Drawing Basics

Taken from the site:

pygame.draw.rect(screen, color, (x,y,width,height), thickness) draws a rectangle (x,y,width,height) is a Python tuple x,y are the coordinates of the upper left hand corner width, height are the width and height of the rectangle thickness is the thickness of the line. If it is zero, the rectangle is filled

With the module pygame.draw shapes like rectangles, circles, polygons, liens, ellipses or arcs can be drawn. Some examples:

pygame.draw.rect draws filled rectangular shapes or outlines. The arguments are the target Surface (i.s. the display), the color, the rectangle and the optional outline width. The rectangle argument is a tuple with the 4 components (x, y, width, height), where (x, y) is the upper left point of the rectangle. Alternatively, the argument can be a pygame.Rect object:

pygame.draw.rect(window, color, (x, y, width, height))

rectangle = pygame.Rect(x, y, width, height)
pygame.draw.rect(window, color, rectangle)

pygame.draw.circle draws filled circles or outlines. The arguments are the target Surface (i.s. the display), the color, the center, the radius and the optional outline width. The center argument is a tuple with the 2 components (x, y):

pygame.draw.circle(window, color, (x, y), radius)

pygame.draw.polygon draws filled polygons or contours. The arguments are the target Surface (i.s. the display), the color, a list of points and the optional contour width. Each point is a tuple with the 2 components (x, y):

pygame.draw.polygon(window, color, [(x1, y1), (x2, y2), (x3, y3)])

Minimal example:

import pygame

pygame.init()

window = pygame.display.set_mode((200, 200))
clock = pygame.time.Clock()

run = True
while run:
    clock.tick(60)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    window.fill((255, 255, 255))

    pygame.draw.rect(window, (0, 0, 255), (20, 20, 160, 160))
    pygame.draw.circle(window, (255, 0, 0), (100, 100), 80)
    pygame.draw.polygon(window, (255, 255, 0), 
        [(100, 20), (100 + 0.8660 * 80, 140), (100 - 0.8660 * 80, 140)])

    pygame.display.flip()

pygame.quit()
exit()
