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。

那么怎么实现自己的打飞机游戏？下面就跟大家一起来动手实现打飞机游戏。全部源代码见文末链接。

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 pygamefrom 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。

我们将子弹定义为独立的模块bullet.py:

import pygameclass 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，定义一个模块supply.py：

import pygamefrom 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：
