Python面向对象实战--飞机大战

时间:2023-01-10 13:56:41


空闲之余学了下Python基础,拿飞机大战练下手熟练,之后更新Python爬虫系列!代码枯燥,我加了很多好玩的表情包,哈哈哈哈!

前言:整体难度不大,要求掌握Pyhton 的面向对象思想。掌握住了面向对象的可以尝试写一下这个项目,巩固学习面向对象!

在main函数页面运行程序即可实现效果

2、游戏说明:

  1. 敌方共有大中小3款飞机,分为高中低三种速度;
  2. 子弹的射程并非全屏,而大概是屏幕长度的80%;
  3. 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;
  4. 每消灭一架小飞机得1000分,中飞机6000分,大飞机10000分;
  5. 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;
  6. 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;
  7. 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。

3、主程序

结合多个模块,把写好的子弹,敌机,补给,飞机设定结合在一起

self.rect.left, self.rect.top = \
randint(0, self.width - self.rect.width), \
randint(-10 * self.height, -5 * self.height)

6、自定义飞机模块

import pygame

# 定义自己的飞机,和前几个很相似
class MyPlane(pygame.sprite.Sprite):
def __init__(self, bg_size):
pygame.sprite.Sprite.__init__(self)

self.image1 = pygame.image.load("plane/images/me1.png").convert_alpha()
self.image2 = pygame.image.load("plane/images/me2.png").convert_alpha()
self.destroy_image = []
self.destroy_image.extend([
pygame.image.load("plane/images/me_destroy_1.png").convert_alpha(),
pygame.image.load("plane/images/me_destroy_2.png").convert_alpha(),
pygame.image.load("plane/images/me_destroy_3.png").convert_alpha(),
pygame.image.load("plane/images/me_destroy_4.png").convert_alpha(),
])
self.active = True
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.mask = pygame.mask.from_surface(self.image1)
self.invincible = False

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

7、补给模块

import pygame
from random import *

# 定义补给类,和前几个也很相似,都是继承赋值
class Bullet_Supply(pygame.sprite.Sprite):
def __init__(self, bg_size):
pygame.sprite.Sprite.__init__(self)

self.image = pygame.image.load("plane/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("plane/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

8、一些细节

  • 路径是容易出错的地方,最简单的方法就是写绝对路径即可!
  • 其他的就都很简单了,主要是掌握整个思路
