前言
我想大家都是有玩過類似飛機(jī)大戰(zhàn)的射擊類游戲，也享受目標(biāo)被消除通過后帶來的愉悅感。
那么如果用Python來實(shí)現(xiàn)飛機(jī)大戰(zhàn)游戲？
下面就跟大家一起用Python來做一個(gè)小游戲，不僅可以從中感受到樂趣，還可以提升自己的能力。
一、游戲設(shè)定
1、游戲界面展示和設(shè)定
游戲的基本設(shè)定:
敵方共有大中小3款飛機(jī)，分為高中低三種速度;
子彈的射程并非全屏,而大概是屏幕長(zhǎng)度的80%;
消滅小飛機(jī)需要1發(fā)子彈,中飛機(jī)需要8發(fā),大飛機(jī)需要20發(fā)子彈;
每消滅一架小飛機(jī)得1000分,中飛機(jī)6000分,大飛機(jī)10000分;
每隔30秒有一個(gè)隨機(jī)的道具補(bǔ)給,分為兩種道具，全屏炸彈和雙倍子彈;
全屏炸彈最多只能存放3枚,雙倍子彈可以維持18秒鐘的效果;
游戲?qū)⒏鶕?jù)分?jǐn)?shù)來逐步提高難度,難度的提高表現(xiàn)為飛機(jī)數(shù)量的增多以及速度的加快。
二、實(shí)現(xiàn)過程
1.我方飛機(jī)
首先創(chuàng)建一個(gè)myplane. py模塊來定義我方飛機(jī):
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)
# 分別定義moveUp()、moveDown()、moveLeft()和moveRight()控制我方飛機(jī)上、下、左、右移動(dòng):
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
2、敵方飛機(jī)
敵機(jī)分為小、中、大三個(gè)尺寸,它們的速度依次是快、中、慢,在游戲界面的上方位置創(chuàng)造位置隨機(jī)的敵機(jī),可以讓它們不在同一排出現(xiàn)。將敵機(jī)的定義寫在enemy. py模塊中
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)
3、定義武器
定義子彈,子彈分為兩種: 一種是普通子彈一次只發(fā)射一顆; 另一種是補(bǔ)給發(fā)放的超級(jí)子彈一次可以發(fā)射兩顆。
我們將子彈定義為獨(dú)立的模塊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
4、武器補(bǔ)充庫：
游戲設(shè)計(jì)每30秒隨機(jī)發(fā)放一個(gè)補(bǔ)給包,可 能是超級(jí)子彈,也可能是全屏炸彈。補(bǔ)給包有自己的圖像和運(yùn)動(dòng)軌跡，定義一個(gè)模塊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
