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＜/code>
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
