前言

我想大家都是有玩过类似飞机大战的射击类游戏，也享受目标被消除通过后带来的愉悦感。

那么如果用Python来实现飞机大战游戏？

下面就跟大家一起用Python来做一个小游戏，不仅可以从中感受到乐趣，还可以提升自己的能力。

一、游戏设定

1、游戏界面展示和设定

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。

二、实现过程

1.我方飞机

首先创建一个myplane. py模块来定义我方飞机:


import pygameclass 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 - 60self.speed = 10self.active = Trueself.invincible = Falseself.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.speedelse:self.rect.top = 0def moveDown(self):if self.rect.bottom < self.height - 60:self.rect.top += self.speedelse:self.rect.bottom = self.height - 60def moveLeft(self):if self.rect.left > 0:self.rect.left -= self.speedelse:self.rect.left = 0def moveRight(self):if self.rect.right < self.width:self.rect.left += self.speedelse:self.rect.right = self.widthdef reset(self):self.rect.left, self.rect.top = \(self.width - self.rect.width) // 2, \self.height - self.rect.height - 60self.active = Trueself.invincible = True

2、敌方飞机

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 = 2self.active = Trueself.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.speedelse:self.reset()def reset(self):self.active = Trueself.rect.left, self.rect.top = \randint(0, self.width - self.rect.width), \randint(-5 * self.height, 0)class MidEnemy(pygame.sprite.Sprite):energy = 8def __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 = 1self.active = Trueself.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.energyself.hit = Falsedef move(self):if self.rect.top < self.height:self.rect.top += self.speedelse:self.reset()def reset(self):self.active = Trueself.energy = MidEnemy.energyself.rect.left, self.rect.top = \randint(0, self.width - self.rect.width), \randint(-10 * self.height, -self.height)class BigEnemy(pygame.sprite.Sprite):energy = 20def __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 = 1self.active = Trueself.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.energyself.hit = Falsedef move(self):if self.rect.top < self.height:self.rect.top += self.speedelse:self.reset()def reset(self):self.active = Trueself.energy = BigEnemy.energyself.rect.left, self.rect.top = \randint(0, self.width - self.rect.width), \randint(-15 * self.height, -5 * self.height)

3、定义武器

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 = positionself.speed = 12self.active = Falseself.mask = pygame.mask.from_surface(self.image)def move(self):self.rect.top -= self.speedif self.rect.top < 0:self.active = Falsedef reset(self, position):self.rect.left, self.rect.top = positionself.active = Trueclass 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 = positionself.speed = 14self.active = Falseself.mask = pygame.mask.from_surface(self.image)def move(self):self.rect.top -= self.speedif self.rect.top < 0:self.active = Falsedef reset(self, position):self.rect.left, self.rect.top = positionself.active = True

4、武器补充库：

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 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), -100self.speed = 5self.active = Falseself.mask = pygame.mask.from_surface(self.image)def move(self):if self.rect.top < self.height:self.rect.top += self.speedelse:self.active = Falsedef reset(self):self.active = Trueself.rect.left, self.rect.bottom = \randint(0, self.width - self.rect.width), -100class 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), -100self.speed = 5self.active = Falseself.mask = pygame.mask.from_surface(self.image)def move(self):if self.rect.top < self.height:self.rect.top += self.speedelse:self.active = Falsedef reset(self):self.active = Trueself.rect.left, self.rect.bottom = \randint(0, self.width - self.rect.width), -100

总结：

以上就是分享的内容！

最后重点是所有的模块应该放在同一个文件夹下，再运行我们的主模块就大功告成了！
