---

1.創建窗口

import pygame import timedef main():#1.創建窗口screen = pygame.display.set_mode((480,852))#2 創建一個背景圖片background = pygame.image.load('./feiji/background.png')while True:#3 顯示到屏幕screen.blit(background,(0,0))pygame.display.update()time.sleep(0.05)if __name__ == '__main__':main()

2.顯示玩家飛機，檢測鍵盤，控制飛機左右移動

import pygame import time from pygame.locals import *class HeroPlane(object):def __init__(self,screen_temp):self.x = 210self.y = 700 self.screen = screen_temp #游戲窗口self.image = pygame.image.load('feiji/hero1.png') def display(self):self.screen.blit(self.image,(self.x,self.y)) #加載玩家飛機到窗口def move_left(self):self.x -= 5def move_right(self):self.x += 5def key_control(hero_temp):# 獲取事件，比如按鍵等for event in pygame.event.get():# 判斷是否是點擊了退出按鈕if event.type == QUIT:print("exit")exit()# 判斷是否是按下了鍵elif event.type == KEYDOWN:# 檢測按鍵是否是a或者leftif event.key == K_a or event.key == K_LEFT:print('left')hero_temp.move_left()# 檢測按鍵是否是d或者rightelif event.key == K_d or event.key == K_RIGHT:print('right')hero_temp.move_right()# 檢測按鍵是否是空格鍵elif event.key == K_SPACE:print('space') def main():#1.創建窗口screen = pygame.display.set_mode((480,852),0,0)#2 創建一個背景圖片background = pygame.image.load('./feiji/background.png')# 創建一個飛機對象hero = HeroPlane(screen)while True:#把背景圖片放到窗口顯示screen.blit(background,(0,0))#顯示玩家飛機到定義的（x,y）坐標位置hero.display()pygame.display.update()#檢測鍵盤，控制玩家飛機移動key_control(hero)time.sleep(0.05)if __name__ == '__main__':main()

3.玩家發射子彈

import pygame import time from pygame.locals import *class HeroPlane(object):def __init__(self,screen_temp):self.x = 210self.y = 700self.screen = screen_temp #游戲窗口self.image = pygame.image.load('feiji/hero1.png')self.bullet_list = [] #存儲發射出去的子彈def display(self):# 加載玩家飛機到窗口self.screen.blit(self.image,(self.x,self.y))for bullet in self.bullet_list:bullet.display()bullet.move()def move_left(self):self.x -= 5def move_right(self):self.x += 5def fire(self):self.bullet_list.append(Bullet(self.screen,self.x,self.y))class Bullet(object):def __init__(self,screen_temp,x,y):self.x = x + 40self.y = y - 20self.screen = screen_tempself.image = pygame.image.load('feiji/bullet.png')def display(self):self.screen.blit(self.image,(self.x,self.y))def move(self):self.y -= 20def key_control(hero_temp):# 獲取事件，比如按鍵等for event in pygame.event.get():# 判斷是否是點擊了退出按鈕if event.type == QUIT:print("exit")exit()# 判斷是否是按下了鍵elif event.type == KEYDOWN:# 檢測按鍵是否是a或者leftif event.key == K_a or event.key == K_LEFT:print('left')hero_temp.move_left()# 檢測按鍵是否是d或者rightelif event.key == K_d or event.key == K_RIGHT:print('right')hero_temp.move_right()# 檢測按鍵是否是空格鍵elif event.key == K_SPACE:print('space')hero_temp.fire() def main():#1.創建窗口screen = pygame.display.set_mode((480,852),0,0)#2 創建一個背景圖片background = pygame.image.load('./feiji/background.png')# 創建一個飛機對象hero = HeroPlane(screen)while True:#把背景圖片放到窗口顯示screen.blit(background,(0,0))#顯示玩家飛機到定義的（x,y）坐標位置hero.display()pygame.display.update()#檢測鍵盤，控制玩家飛機移動key_control(hero)time.sleep(0.05)if __name__ == '__main__':main()

效果如下：

?4.創建一個敵機

--snip-- class EnemyPlane(object):def __init__(self,screen_temp):self.x = 0self.y = 0self.screen = screen_tempself.image = pygame.image.load('feiji/enemy0.png')def display(self):self.screen.blit(self.image,(self.x,self.y))--snip--def main():--snip--#4 創建一個敵機enemy = EnemyPlane(screen)while True:--snip--enemy.display()--snip

5.控制敵機左右移動

--snip-- class EnemyPlane(object):def __init__(self,screen_temp):--snip--self.direction = 'right' #定義敵機默認往右移動--snip--def move(self):if self.direction == 'right':self.x += 8elif self.direction == 'left':self.x -= 8if self.x > 430:self.direction = 'left'elif self.x < 0:self.direction = 'right' --snip--def main():--snip--#4 創建一個敵機enemy = EnemyPlane(screen)enemy.move()--snip-- import pygame import time from pygame.locals import *class HeroPlane(object):def __init__(self,screen_temp):self.x = 210self.y = 700self.screen = screen_temp #游戲窗口self.image = pygame.image.load('feiji/hero1.png')self.bullet_list = [] #存儲發射出去的子彈def display(self):# 加載玩家飛機到窗口self.screen.blit(self.image,(self.x,self.y))for bullet in self.bullet_list:bullet.display()bullet.move()def move_left(self):self.x -= 5def move_right(self):self.x += 5def fire(self):self.bullet_list.append(Bullet(self.screen,self.x,self.y))class EnemyPlane(object):def __init__(self,screen_temp):self.x = 0self.y = 0self.screen = screen_tempself.image = pygame.image.load('feiji/enemy0.png')self.direction = 'right' #定義敵機默認往右移動def display(self):self.screen.blit(self.image,(self.x,self.y))def move(self):if self.direction == 'right':self.x += 8elif self.direction == 'left':self.x -= 8if self.x > 430:self.direction = 'left'elif self.x < 0:self.direction = 'right'class Bullet(object):def __init__(self,screen_temp,x,y):self.x = x + 40self.y = y - 20self.screen = screen_tempself.image = pygame.image.load('feiji/bullet.png')def display(self):self.screen.blit(self.image,(self.x,self.y))def move(self):self.y -= 20def key_control(hero_temp):# 獲取事件，比如按鍵等for event in pygame.event.get():# 判斷是否是點擊了退出按鈕if event.type == QUIT:print("exit")exit()# 判斷是否是按下了鍵elif event.type == KEYDOWN:# 檢測按鍵是否是a或者leftif event.key == K_a or event.key == K_LEFT:print('left')hero_temp.move_left()# 檢測按鍵是否是d或者rightelif event.key == K_d or event.key == K_RIGHT:print('right')hero_temp.move_right()# 檢測按鍵是否是空格鍵elif event.key == K_SPACE:print('space')hero_temp.fire() def main():#1.創建窗口screen = pygame.display.set_mode((480,852),0,0)#2 創建一個背景圖片background = pygame.image.load('./feiji/background.png')#3 創建一個飛機對象hero = HeroPlane(screen)#4 創建一個敵機enemy = EnemyPlane(screen)while True:#把背景圖片放到窗口顯示screen.blit(background,(0,0))#顯示玩家飛機到定義的（x,y）坐標位置hero.display()enemy.display()enemy.move()pygame.display.update()#檢測鍵盤，控制玩家飛機移動key_control(hero)time.sleep(0.05)if __name__ == '__main__':main() 完整代碼

6.刪除子彈，只要發射出去的子彈超過邊界就刪掉

--snip-- class HeroPlane(object):--snip----snip--bullet.move()if bullet.judge(): #判斷子彈是否越界self.bullet_list.remove(bullet) --snip--class Bullet(object):--sinp--def judge(self):if self.y < 0:return Trueelse:return False--snip import pygame import time from pygame.locals import *class HeroPlane(object):def __init__(self,screen_temp):self.x = 210self.y = 700self.screen = screen_temp #游戲窗口self.image = pygame.image.load('feiji/hero1.png')self.bullet_list = [] #存儲發射出去的子彈def display(self):# 加載玩家飛機到窗口self.screen.blit(self.image,(self.x,self.y))for bullet in self.bullet_list:bullet.display()bullet.move()if bullet.judge(): #判斷子彈是否越界self.bullet_list.remove(bullet)def move_left(self):self.x -= 5def move_right(self):self.x += 5def fire(self):self.bullet_list.append(Bullet(self.screen,self.x,self.y))class EnemyPlane(object):def __init__(self,screen_temp):self.x = 0self.y = 0self.screen = screen_tempself.image = pygame.image.load('feiji/enemy0.png')self.direction = 'right' #定義敵機默認往右移動def display(self):self.screen.blit(self.image,(self.x,self.y))def move(self):if self.direction == 'right':self.x += 8elif self.direction == 'left':self.x -= 8if self.x > 430:self.direction = 'left'elif self.x < 0:self.direction = 'right'class Bullet(object):def __init__(self,screen_temp,x,y):self.x = x + 40self.y = y - 20self.screen = screen_tempself.image = pygame.image.load('feiji/bullet.png')def display(self):self.screen.blit(self.image,(self.x,self.y))def move(self):self.y -= 20def judge(self):if self.y < 200:return Trueelse:return Falsedef key_control(hero_temp):# 獲取事件，比如按鍵等for event in pygame.event.get():# 判斷是否是點擊了退出按鈕if event.type == QUIT:print("exit")exit()# 判斷是否是按下了鍵elif event.type == KEYDOWN:# 檢測按鍵是否是a或者leftif event.key == K_a or event.key == K_LEFT:print('left')hero_temp.move_left()# 檢測按鍵是否是d或者rightelif event.key == K_d or event.key == K_RIGHT:print('right')hero_temp.move_right()# 檢測按鍵是否是空格鍵elif event.key == K_SPACE:print('space')hero_temp.fire() def main():#1.創建窗口screen = pygame.display.set_mode((480,852),0,0)#2 創建一個背景圖片background = pygame.image.load('./feiji/background.png')#3 創建一個飛機對象hero = HeroPlane(screen)#4 創建一個敵機enemy = EnemyPlane(screen)while True:#把背景圖片放到窗口顯示screen.blit(background,(0,0))#顯示玩家飛機到定義的（x,y）坐標位置hero.display()enemy.display()enemy.move()pygame.display.update()#檢測鍵盤，控制玩家飛機移動key_control(hero)time.sleep(0.05)if __name__ == '__main__':main() 完整代碼

7.添加敵機放射子彈功能

使用random來控制敵機發射子彈的頻率

--snip-- import randomclass EnemyPlane(object):--snip - -self.bullet_list = [] #存儲發射出去的子彈self.direction = 'right' #定義敵機默認往右移動def display(self):--snip - -bullet.move()if bullet.judge(): #判斷子彈是否越界self.bullet_list.remove(bullet)--snip--def fire(self):#控制子彈頻率random_num = random.randint(1,80)if random_num == 10 or random_num == 40:self.bullet_list.append(EnemyBullet(self.screen,self.x,self.y)) --snip--class EnemyBullet(object):def __init__(self,screen_temp,x,y):self.x = x + 25self.y = y + 40self.screen = screen_tempself.image = pygame.image.load('feiji/bullet1.png')def display(self):self.screen.blit(self.image,(self.x,self.y))def move(self):self.y += 10def judge(self):if self.y > 852:return Trueelse:return False--snip - -while True:--snip - -enemy.move()enemy.fire()--snip-- import pygame import time from pygame.locals import * import randomclass HeroPlane(object):def __init__(self,screen_temp):self.x = 210self.y = 700self.screen = screen_temp #游戲窗口self.image = pygame.image.load('feiji/hero1.png')self.bullet_list = [] #存儲發射出去的子彈def display(self):# 加載玩家飛機到窗口self.screen.blit(self.image,(self.x,self.y))for bullet in self.bullet_list:bullet.display()bullet.move()if bullet.judge(): #判斷子彈是否越界self.bullet_list.remove(bullet)def move_left(self):self.x -= 5def move_right(self):self.x += 5def fire(self):self.bullet_list.append(Bullet(self.screen,self.x,self.y))class EnemyPlane(object):def __init__(self,screen_temp):self.x = 0self.y = 0self.screen = screen_tempself.image = pygame.image.load('feiji/enemy0.png')self.bullet_list = [] #存儲發射出去的子彈self.direction = 'right' #定義敵機默認往右移動def display(self):self.screen.blit(self.image,(self.x,self.y))for bullet in self.bullet_list:bullet.display()bullet.move()if bullet.judge(): #判斷子彈是否越界self.bullet_list.remove(bullet)def move(self):if self.direction == 'right':self.x += 8elif self.direction == 'left':self.x -= 8if self.x > 430:self.direction = 'left'elif self.x < 0:self.direction = 'right'def fire(self):random_num = random.randint(1,80)if random_num == 10 or random_num == 40:self.bullet_list.append(EnemyBullet(self.screen,self.x,self.y))class Bullet(object):def __init__(self,screen_temp,x,y):self.x = x + 40self.y = y - 20self.screen = screen_tempself.image = pygame.image.load('feiji/bullet.png')def display(self):self.screen.blit(self.image,(self.x,self.y))def move(self):self.y -= 20def judge(self):if self.y < 0:return Trueelse:return Falseclass EnemyBullet(object):def __init__(self,screen_temp,x,y):self.x = x + 25self.y = y + 40self.screen = screen_tempself.image = pygame.image.load('feiji/bullet1.png')def display(self):self.screen.blit(self.image,(self.x,self.y))def move(self):self.y += 10def judge(self):if self.y > 852:return Trueelse:return Falsedef key_control(hero_temp):# 獲取事件，比如按鍵等for event in pygame.event.get():# 判斷是否是點擊了退出按鈕if event.type == QUIT:print("exit")exit()# 判斷是否是按下了鍵elif event.type == KEYDOWN:# 檢測按鍵是否是a或者leftif event.key == K_a or event.key == K_LEFT:print('left')hero_temp.move_left()# 檢測按鍵是否是d或者rightelif event.key == K_d or event.key == K_RIGHT:print('right')hero_temp.move_right()# 檢測按鍵是否是空格鍵elif event.key == K_SPACE:print('space')hero_temp.fire()def main():#1.創建窗口screen = pygame.display.set_mode((480,852),0,0)#2 創建一個背景圖片background = pygame.image.load('./feiji/background.png')#3 創建一個飛機對象hero = HeroPlane(screen)#4 創建一個敵機enemy = EnemyPlane(screen)while True:#把背景圖片放到窗口顯示screen.blit(background,(0,0))#顯示玩家飛機到定義的（x,y）坐標位置hero.display()enemy.display()enemy.move()enemy.fire()pygame.display.update()#檢測鍵盤，控制玩家飛機移動key_control(hero)time.sleep(0.05)if __name__ == '__main__':main() 完整代碼
