pygame系列小程序：移動的小車

        最近一個星期學習了一下python的pygame模塊，順便做個小程序鞏固所學的，運行效果如下：

        其中，背景圖"highway.jpg"是使用PhotoShop將其分辨率改變為640 × 480，而小車"car.png"則是將其轉變為png格式的圖片，並且填充其背景色，讓其擁有透明性。

# -*- coding: utf-8 -*-

# 背景圖以及移動小車圖
highway_image_name = "highway.jpg"
car_image_name = "car.png"

# 導入程序相關的模塊
import pygame
from pygame.locals import *
from sys import exit

pygame.init()

# 生成窗口以及窗口標題
screen = pygame.display.set_mode((640, 480), 0, 32)
pygame.display.set_caption("Little Case")

# 加載並轉換圖片
highway = pygame.image.load(highway_image_name).convert()
car = pygame.image.load(car_image_name).convert_alpha()

x = 0
y = 300
z = 1

# 加載以及渲染字體
my_font = pygame.font.SysFont("arial", 16)
text_surface = my_font.render(("%d car" % (z)), True, (0, 0, 255))

# 主循環
while True:
    
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.display.quit()
            exit()

    # 矩形顏色坐標等   
    rc = (0, 250, 0)
    rp = (560, 0)
    rs = (639, 60)

    x += 0.2
    if x > 640 + car.get_width():
        x = -car.get_width()
        z += 1
        text_surface = my_font.render(("%d cars" % z), True, (0, 0, 255))

    screen.blit(highway, (0, 0))
    screen.blit(text_surface, (620 - text_surface.get_width(), text_surface.get_height()))
    screen.blit(car, (x, y))
    pygame.draw.rect(screen, rc, Rect(rp, rs), 1)  #   Rect(左上角的坐標，右下角的坐標)
    
    pygame.display.update()
