文章目录经典飞机大战一.游戏设定二.我方飞机三.敌方飞机四.发射子弹五.发放补给包六.主模块 经典飞机大战 不知道大家有没有打过飞机,喜不喜欢打飞机。当我第一次接触这个东西的时候,我的内心是被震撼到的。第一次接触打飞机的时候作者本人是身心愉悦的,因为周边的朋友都在打飞机, 每次都会下意识彼此较量一下,看谁打得更好。打飞机也是需要有一定的技巧的,熟练的朋友一把能打上半个小时,生疏的则三五分钟就败下阵来。 一.游戏设定 游戏界面如下图所示 游戏的基本设定: 敌方共有大中小3款飞机，分为高中低三种速度; 子弹的射程并非全屏,而大概是屏幕长度的80%; 消灭小飞机需要1发子弹,中飞机需要8发,大飞机需要20发子弹; 每消灭一架小飞机得1000分,中飞机6000分,大飞机10000分; 每隔30秒有一个随机的道具补给,分为两种道具，全屏炸弹和双倍子弹; 全屏炸弹最多只能存放3枚,双倍子弹可以维持18秒钟的效果; 游戏将根据分数来逐步提高难度,难度的提高表现为飞机数量的增多以及速度的加快。 另外还对游戏做了一些改进,比如为中飞机和大飞机增加了血槽的显示,这样玩家可以直观地知道敌机快被消灭了没有;我方有三次机会,每次被敌人消灭,新诞生的飞机会有3秒钟的安全期;游戏结束后会显示历史最高分数。 这个游戏加上基本的注释代码量在800行左右,代码看上去比较多，多打代码少动脑。所以大家不要怕,越是多的代码,逻辑就越容易看得清楚，就越好学习。好,那让我们从无到有,从简单到复杂来一起打造这个游戏吧!   二.我方飞机首先创建一个myplane. py模块来定义我方飞机: import pygame class MyPlane(pygame.sprite.Sprite): def __init__(self, bg_size): pygame.sprite.Sprite.__init__(self) self.image1 = pygame.image.load("images/me1.png").convert_alpha() self.image2 = pygame.image.load("images/me2.png").convert_alpha() self.destroy_images = [] self.destroy_images.extend([\ pygame.image.load("images/me_destroy_1.png").convert_alpha(), \ pygame.image.load("images/me_destroy_2.png").convert_alpha(), \ pygame.image.load("images/me_destroy_3.png").convert_alpha(), \ pygame.image.load("images/me_destroy_4.png").convert_alpha() \ ]) self.rect = self.image1.get_rect() self.width, self.height = bg_size[0], bg_size[1] self.rect.left, self.rect.top = \ (self.width - self.rect.width) // 2, \ self.height - self.rect.height - 60 self.speed = 10 self.active = True self.invincible = False self.mask = pygame.mask.from_surface(self.image1) # 分别定义moveUp()、moveDown()、moveLeft()和moveRight()控制我方飞机上、下、左、右移动: def moveUp(self): if self.rect.top > 0: self.rect.top -= self.speed else: self.rect.top = 0 def moveDown(self): if self.rect.bottom < self.height - 60: self.rect.top += self.speed else: self.rect.bottom = self.height - 60三.敌方飞机既然英雄已经有了,那现在就是需要创造敌人的时候。敌机分为小、中、大三个尺寸,它们的速度依次是快、中、慢,在游戏界面的上方位置创造位置随机的敌机,可以让它们不在同一排出现。将敌机的定义写在enemy. py模块中: import pygame from random import * class SmallEnemy(pygame.sprite.Sprite): def __init__(self, bg_size): pygame.sprite.Sprite.__init__(self) self.image = pygame.image.load("images/enemy1.png").convert_alpha() self.destroy_images = [] self.destroy_images.extend([ \ pygame.image.load("images/enemy1_down1.png").convert_alpha(), \ pygame.image.load("images/enemy1_down2.png").convert_alpha(), \ pygame.image.load("images/enemy1_down3.png").convert_alpha(), \ pygame.image.load("images/enemy1_down4.png").convert_alpha() \ ]) self.rect = self.image.get_rect() self.width, self.height = bg_size[0], bg_size[1] self.speed = 2 self.active = True self.rect.left, self.rect.top = \ randint(0, self.width - self.rect.width), \ randint(-5 * self.height, 0) self.mask = pygame.mask.from_surface(self.image) def move(self): if self.rect.top < self.height: self.rect.top += self.speed else: self.reset() def reset(self): self.active = True self.rect.left, self.rect.top = \ randint(0, self.width - self.rect.width), \ randint(-5 * self.height, 0) class MidEnemy(pygame.sprite.Sprite): energy = 8 def __init__(self, bg_size): pygame.sprite.Sprite.__init__(self) self.image = pygame.image.load("images/enemy2.png").convert_alpha() self.image_hit = pygame.image.load("images/enemy2_hit.png").convert_alpha() self.destroy_images = [] self.destroy_images.extend([ \ pygame.image.load("images/enemy2_down1.png").convert_alpha(), \ pygame.image.load("images/enemy2_down2.png").convert_alpha(), \ pygame.image.load("images/enemy2_down3.png").convert_alpha(), \ pygame.image.load("images/enemy2_down4.png").convert_alpha() \ ]) self.rect = self.image.get_rect() self.width, self.height = bg_size[0], bg_size[1] self.speed = 1 self.active = True self.rect.left, self.rect.top = \ randint(0, self.width - self.rect.width), \ randint(-10 * self.height, -self.height) self.mask = pygame.mask.from_surface(self.image) self.energy = MidEnemy.energy self.hit = False def move(self): if self.rect.top < self.height: self.rect.top += self.speed else: self.reset() def reset(self): self.active = True self.energy = MidEnemy.energy self.rect.left, self.rect.top = \ randint(0, self.width - self.rect.width), \ randint(-10 * self.height, -self.height) class BigEnemy(pygame.sprite.Sprite): energy = 20 def __init__(self, bg_size): pygame.sprite.Sprite.__init__(self) self.image1 = pygame.image.load("images/enemy3_n1.png").convert_alpha() self.image2 = pygame.image.load("images/enemy3_n2.png").convert_alpha() self.image_hit = pygame.image.load("images/enemy3_hit.png").convert_alpha() self.destroy_images = [] self.destroy_images.extend([ \ pygame.image.load("images/enemy3_down1.png").convert_alpha(), \ pygame.image.load("images/enemy3_down2.png").convert_alpha(), \ pygame.image.load("images/enemy3_down3.png").convert_alpha(), \ pygame.image.load("images/enemy3_down4.png").convert_alpha(), \ pygame.image.load("images/enemy3_down5.png").convert_alpha(), \ pygame.image.load("images/enemy3_down6.png").convert_alpha() \ ])四.发射子弹现在的情况是我方飞机处于落后挨打的状态,敌强我弱,所以应该拿起武器进行反击! 接下来定义子弹,子弹分为两种: 一种是普通子弹一次只发射一颗; 另一种是补给发放的超级子弹一次可以发射两颗。  我们将子弹定义为独立的模块bullet.py: import pygame class Bullet1(pygame.sprite.Sprite): def __init__(self, position): pygame.sprite.Sprite.__init__(self) self.image = pygame.image.load("images/bullet1.png").convert_alpha() self.rect = self.image.get_rect() self.rect.left, self.rect.top = position self.speed = 12 self.active = False self.mask = pygame.mask.from_surface(self.image) def move(self): self.rect.top -= self.speed if self.rect.top < 0: self.active = False def reset(self, position): self.rect.left, self.rect.top = position self.active = True class Bullet2(pygame.sprite.Sprite): def __init__(self, position): pygame.sprite.Sprite.__init__(self) self.image = pygame.image.load("images/bullet2.png").convert_alpha() self.rect = self.image.get_rect() self.rect.left, self.rect.top = position self.speed = 14 self.active = False self.mask = pygame.mask.from_surface(self.image) def move(self): self.rect.top -= self.speed if self.rect.top < 0: self.active = False def reset(self, position): self.rect.left, self.rect.top = position self.active = True五.发放补给包游戏设计每30秒随机发放一个补给包,可 能是超级子弹,也可能是全屏炸弹。补给包有自己的图像和运动轨迹,不妨单独为其定义一个模块supply.py: import pygame from random import * class Bullet_Supply(pygame.sprite.Sprite): def __init__(self, bg_size): pygame.sprite.Sprite.__init__(self) self.image = pygame.image.load("images/bullet_supply.png").convert_alpha() self.rect = self.image.get_rect() self.width, self.height = bg_size[0], bg_size[1] self.rect.left, self.rect.bottom = \ randint(0, self.width - self.rect.width), -100 self.speed = 5 self.active = False self.mask = pygame.mask.from_surface(self.image) def move(self): if self.rect.top < self.height: self.rect.top += self.speed else: self.active = False def reset(self): self.active = True self.rect.left, self.rect.bottom = \ randint(0, self.width - self.rect.width), -100 class Bomb_Supply(pygame.sprite.Sprite): def __init__(self, bg_size): pygame.sprite.Sprite.__init__(self) self.image = pygame.image.load("images/bomb_supply.png").convert_alpha() self.rect = self.image.get_rect() self.width, self.height = bg_size[0], bg_size[1] self.rect.left, self.rect.bottom = \ randint(0, self.width - self.rect.width), -100 self.speed = 5 self.active = False self.mask = pygame.mask.from_surface(self.image) def move(self): if self.rect.top < self.height: self.rect.top += self.speed else: self.active = False def reset(self): self.active = True self.rect.left, self.rect.bottom = \ randint(0, self.width - self.rect.width), -100六.主模块所有的模块都到齐了，接下来就该实现我们的主模块了 # main.py import pygame import sys import traceback import myplane import enemy import bullet import supply from pygame.locals import * from random import * pygame.init() pygame.mixer.init() bg_size = width, height = 480, 700 screen = pygame.display.set_mode(bg_size) pygame.display.set_caption("飞机大战 -- FishC Demo") background = pygame.image.load("images/background.png").convert() BLACK = (0, 0, 0) WHITE = (255, 255, 255) GREEN = (0, 255, 0) RED = (255, 0, 0) # 载入游戏音乐 pygame.mixer.music.load("sound/game_music.ogg") pygame.mixer.music.set_volume(0.2) bullet_sound = pygame.mixer.Sound("sound/bullet.wav") bullet_sound.set_volume(0.2) bomb_sound = pygame.mixer.Sound("sound/use_bomb.wav") bomb_sound.set_volume(0.2) supply_sound = pygame.mixer.Sound("sound/supply.wav") supply_sound.set_volume(0.2) get_bomb_sound = pygame.mixer.Sound("sound/get_bomb.wav") get_bomb_sound.set_volume(0.2) get_bullet_sound = pygame.mixer.Sound("sound/get_bullet.wav") get_bullet_sound.set_volume(0.2) upgrade_sound = pygame.mixer.Sound("sound/upgrade.wav") upgrade_sound.set_volume(0.2) enemy3_fly_sound = pygame.mixer.Sound("sound/enemy3_flying.wav") enemy3_fly_sound.set_volume(0.2) enemy1_down_sound = pygame.mixer.Sound("sound/enemy1_down.wav") enemy1_down_sound.set_volume(0.2) enemy2_down_sound = pygame.mixer.Sound("sound/enemy2_down.wav") enemy2_down_sound.set_volume(0.2) enemy3_down_sound = pygame.mixer.Sound("sound/enemy3_down.wav") enemy3_down_sound.set_volume(0.5) me_down_sound = pygame.mixer.Sound("sound/me_down.wav") me_down_sound.set_volume(0.2) def add_small_enemies(group1, group2, num): for i in range(num): e1 = enemy.SmallEnemy(bg_size) group1.add(e1) group2.add(e1) def add_mid_enemies(group1, group2, num): for i in range(num): e2 = enemy.MidEnemy(bg_size) group1.add(e2) group2.add(e2) def add_big_enemies(group1, group2, num): for i in range(num): e3 = enemy.BigEnemy(bg_size) group1.add(e3) group2.add(e3) def inc_speed(target, inc): for each in target: each.speed += inc def main(): pygame.mixer.music.play(-1) # 生成我方飞机 me = myplane.MyPlane(bg_size) enemies = pygame.sprite.Group() # 生成敌方小型飞机 small_enemies = pygame.sprite.Group() add_small_enemies(small_enemies, enemies, 15) # 生成敌方中型飞机 mid_enemies = pygame.sprite.Group() add_mid_enemies(mid_enemies, enemies, 4) # 生成敌方大型飞机 big_enemies = pygame.sprite.Group() add_big_enemies(big_enemies, enemies, 2) # 生成普通子弹 bullet1 = [] bullet1_index = 0 BULLET1_NUM = 4 for i in range(BULLET1_NUM): bullet1.append(bullet.Bullet1(me.rect.midtop)) # 生成超级子弹 bullet2 = [] bullet2_index = 0 BULLET2_NUM = 8 for i in range(BULLET2_NUM // 2): bullet2.append(bullet.Bullet2((me.rect.centerx -
