Python通过Pygame绘制移动的矩形实例代码

Pygame是一个多用于游戏开发的模块。

本文实例主要是在演示框里实现一个移动的矩形实例代码,完整代码如下:

#moving rectangle project

import pygame

from pygame.locals import *

pygame.init()

screen = pygame.display.set_mode((600,500))

pygame.display.set_caption("Drawing Rectangles")

pos_x = 300

pos_y = 250

vel_x = 2

vel_y = 1

while True:

for event in pygame.event.get():

if event.type in (QUIT,KEYDOWN):

pygame.quit()

screen.fill((0,0,200))

# move the rectangle

pos_x += vel_x

pos_y += vel_y

# keep rectangle on the screen

if pos_x > 500 or pos_x < 0:

vel_x = -vel_x

if pos_y > 400 or pos_y < 0:

vel_y = -vel_y

# draw the rectangle

color = 255,255,0

width = 0 #solid fill

pos = pos_x,pos_y,100,100

pygame.draw.rect(screen,color,pos,width)

pygame.display.update()

演示如下:
