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:
