## 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
    
        def moveLeft(self):
            if self.rect.left > 0:
                self.rect.left -= self.speed
            else:
                self.rect.left = 0
    
        def moveRight(self):
            if self.rect.right < self.width:
                self.rect.left += self.speed
            else:
                self.rect.right = self.width
    
        def reset(self):
            self.rect.left, self.rect.top = \
                            (self.width - self.rect.width) // 2, \
                            self.height - self.rect.height - 60
            self.active = True
            self.invincible = True

### 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() \
                ])
            self.rect = self.image1.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(-15 * self.height, -5 * self.height)
            self.mask = pygame.mask.from_surface(self.image1)
            self.energy = BigEnemy.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 = BigEnemy.energy
            self.rect.left, self.rect.top = \
                randint(0, self.width - self.rect.width), \
                randint(-15 * self.height, -5 * self.height)

### 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。  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQzMzI4MDQw_size_16_color_FFFFFF_t_70 2]

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
