本章开始学习pygame
12-1 蓝色天空
一开始我完全是根据书上的例子写的,然而将12-1不需要的代码删除,结果Pygame窗口发生了未响应的状况,检查后得知是因为我将监视输入的代码也删掉了,因此无法响应我的外部输入……
import sys #use this module to quit import pygame def run_game(): #initialize the background pygame.init() #create a window screen = pygame.display.set_mode((500, 500)) #set window title pygame.display.set_caption("BLUE!") while True: for event in pygame.event.get(): if event.type == pygame.QUIT: sys.exit() screen.fill((35, 70, 188)) pygame.display.flip() run_game()
12-2 游戏角色
随便找一张图好了,可是我并不知道要如何将屏幕背景色设置为图像背景色!
import pygame class Character(): def __init__(self, screen): #get the screen self.screen = screen #load the image self.image = pygame.image.load('HTF.bmp') #get the object: rect #rect has parameters: center, centerx, centery # top, bottom, left, right self.rect = self.image.get_rect() self.screen_rect = screen.get_rect() #put the ship on the bottom self.rect.center = self.screen_rect.center #draw the image def blitme(self): self.screen.blit(self.image, self.rect)
import sys #use this module to quit import pygame from character import Character def run_game(): #initialize the background pygame.init() #create a window screen = pygame.display.set_mode((236, 264)) #set window title pygame.display.set_caption("None") char = Character(screen) while True: for event in pygame.event.get(): if event.type == pygame.QUIT: sys.exit() screen.fill((255, 194, 136)) char.blitme() pygame.display.flip() run_game()
12-3 火箭
由于作业操作比较少,于是我没有分太多的项目
import pygame class Character(): def __init__(self, screen): #get the screen self.screen = screen #load the image self.image = pygame.image.load('rocket.bmp') #get the object: rect #rect has parameters: center, centerx, centery # top, bottom, left, right self.rect = self.image.get_rect() self.screen_rect = screen.get_rect() #put the ship on the bottom self.rect.center = self.screen_rect.center #moving symbol self.moving_right = False self.moving_left = False self.moving_top = False self.moving_bottom = False def update(self): #check moving symbol if self.moving_right and self.rect.right < self.screen_rect.right: self.rect.centerx += 1 if self.moving_left and self.rect.left > 0: self.rect.centerx -= 1 if self.moving_top and self.rect.top > 0: self.rect.centery -= 1 if self.moving_bottom and self.rect.bottom < self.screen_rect.bottom: self.rect.centery += 1 #draw the image def blitme(self): self.screen.blit(self.image, self.rect)
import sys #use this module to quit import pygame from character import Character def run_game(): #initialize the background pygame.init() #create a window screen = pygame.display.set_mode((500, 500)) #set window title pygame.display.set_caption("None") char = Character(screen) while True: #spy the keyboard and mouse to quit for event in pygame.event.get(): if event.type == pygame.QUIT: sys.exit() #if put down one key elif event.type == pygame.KEYDOWN: if event.key == pygame.K_RIGHT: char.moving_right = True elif event.key == pygame.K_LEFT: char.moving_left = True elif event.key == pygame.K_UP: char.moving_top = True elif event.key == pygame.K_DOWN: char.moving_bottom = True #if release this key elif event.type == pygame.KEYUP: if event.key == pygame.K_RIGHT: char.moving_right = False elif event.key == pygame.K_LEFT: char.moving_left = False elif event.key == pygame.K_UP: char.moving_top = False elif event.key == pygame.K_DOWN: char.moving_bottom = False char.update() screen.fill((255, 255, 255)) char.blitme() pygame.display.flip() run_game()
结果是正常运行:
