python使用pygame模块实现坦克大战游戏

时间:2021-04-03 人气:0

首先，第一步，游戏简单素材的准备。

炮弹，炮弹，坦克移动。音乐-开火素材。

其次，思路整理。

我们需要几个类，分别是玩家类，敌人类，炮弹类及地图类，开始游戏界面以及结束界面，血条等等。

开始coding。

主函数，new一个对象（java乱入emmm），声明一个对象。

# encoding : utf-8
# anthor : comi
from gameloop import *
from pygame import *
import pygame,sys,time
 
if __name__ == '__main__':
 player = game() # 声明一个类对象
 player.game_start('KEEP-GOING') # 调用开始函数
 while player.playing: # 进入游戏运行
  player.new() # 开始游戏
 player.screen.fill(black)
 player.game_start('GAME-OVER') # 游戏结束
 time.sleep(1.5) # 可以不要

这里可以根据自己的需要进行更改相关代码

接下来游戏的主循环

# encoding : utf-8
# author : comi
from setting import *
from pygame import *
from Sprite import *
import pygame,sys
vec = pygame.math.Vector2
 
 
class game: # 游戏类 包含循环等
 def __init__(self): # 初始化
  pygame.init() # pygame 初始化
  pygame.display.set_caption("Keep-Going") # 游戏窗口 左上角名称
  self.screen = pygame.display.set_mode((width, height)) # 游戏窗口的大小
  self.FpsClock = pygame.time.Clock() # 设置游戏的刷新率
  self.playing = True # 进入游戏的状态
  self.running = True # 游戏运行的状态
  self.Waiting = True # 游戏等待的状态
  self.Pblood = 100 # 玩家血量
  self.Eblood = 100 # 敌人血量
  self.player = Player() # 声明一个游戏玩家对象
  self.enemy = Enemy() # 声明一个敌人对象
  self.all_groups = pygame.sprite.Group() # 通过pygame自带的 group 来判断碰撞检测
  self.player_groups = pygame.sprite.Group()
  self.Map_groups = pygame.sprite.Group()
  self.Enemy_groups = pygame.sprite.Group()
 
 def new(self): # 开始一个游戏
  self.player_groups.add(self.player) # 将玩家添加到玩家组
  self.all_groups.add(self.player) # 将玩家添加到 所有组
 
  self.Enemy_groups.add(self.enemy)
  self.all_groups.add(self.enemy)
 
  for platfroms in Map1: # 地图
   p = Platform(*platfroms)  # 取出所有值
   self.Map_groups.add(p)
   self.all_groups.add(p)
 
  self.run() # 调用函数运行游戏

  self.text_draw(width / 2, height * 3 / 4, 25,'Press any key to continue',) # 文本
  pygame.display.update() # 更行展示
  while self.Waiting: # 实现 按键等待开始效果
   for event in pygame.event.get():
    if event.type == pygame.QUIT:
     pygame.quit()
     sys.exit()
    if event.type == pygame.KEYDOWN: 
     self.Waiting = False

  hit = pygame.sprite.groupcollide(self.player.Bullet_groups, self.Map_groups, True,False) # 子弹碰墙消失
  hit = pygame.sprite.groupcollide(self.enemy.Bullet_groups, self.Map_groups, True, False)
 
  PMC = pygame.sprite.spritecollide(self.player,self.Map_groups,False,False)  # 撞墙
  if PMC:
   key_pressed = pygame.key.get_pressed()
   if key_pressed[pygame.K_a]:
    self.player.pos.x = self.player.pos.x + gap
   if key_pressed[pygame.K_d]:
    self.player.pos.x = self.player.pos.x - gap
   if key_pressed[pygame.K_w]:

   if key_pressed[pygame.K_UP]:

   self.update() 
 
   f self.Eblood <= 0: # enemy 
    self.screen.fill(black)
    self.game_start('P1 WIN!')
    time.sleep(1.5)
    self.running = False
    self.playing = False
 
   if self.Pblood <= 0: # Player
    self.screen.fill(black)
    self.game_start('P2 WIN!')
    time.sleep(1.5)
    self.running = False
    self.playing = False
 
 def text_draw(self, x, y, size, text): # 文本展示函数
  self.font = pygame.font.Font('freesansbold.ttf', size) # 字体，大小
  self.text_surf = self.font.render(text, True, red) # 颜色
  self.text_rect = self.text_surf.get_rect() # 矩形
  self.text_rect.center = (x, y) # 位置
  self.screen.blit(self.text_surf, self.text_rect) # 覆盖展示
 
 def draw_pic(self): 
  self.screen.fill(white) # 背景
  self.text_draw(900,50,30,"KEEP") # 文本
  self.text_draw(900, 100, 30, "GOING")
 
  self.text_draw(820, 150, 20, "P1:")
  self.text_draw(820, 200, 20, "P2:")
  
  self.text_draw(900, 250, 20, "Attention!")
  self.text_draw(900,300,20,"The Bullet Can")
  self.text_draw(900, 350, 20, "Be Control!")
  self.bar_draw(850, 145, self.Pblood) # 血条
  hit = pygame.sprite.groupcollide(self.enemy.Bullet_groups, self.player_groups, True, False) # 血条减少
  if hit:
   self.Pblood = self.Pblood - randint(10, 15)
   self.bar_draw(850, 145, self.Pblood)
 
  self.bar_draw(850, 195, self.Eblood)
  hit = pygame.sprite.groupcollide(self.player.Bullet_groups, self.Enemy_groups, True, False)
  if hit:
   self.Eblood = self.Eblood - randint(10, 15)
   self.bar_draw(850, 195, self.Eblood)
 
  self.Map_groups.draw(self.screen) # 画出图片
  self.player_groups.draw(self.screen)
  self.Enemy_groups.draw(self.screen)
  self.player.Bullet_groups.draw(self.screen)
  self.enemy.Bullet_groups.draw(self.screen)
 
  pygame.display.update() 
 
 def bar_draw(self, x, y, pct): # 血条函数
  # draw a bar 
  if pct <= 0:
   pct = 0
  Bar_Lenth = 100
  Bar_Height = 10
  Fill_Lenth = (pct / 100) * Bar_Lenth
  Out_rect = pygame.Rect(x, y, Bar_Lenth, Bar_Height)
  Fill_rect = pygame.Rect(x, y, Fill_Lenth, Bar_Height)
  pygame.draw.rect(self.screen, green, Fill_rect)
  pygame.draw.rect(self.screen, red, Out_rect, 2)
 
 def events(self): # 事件
  for events in pygame.event.get():
   if events.type == pygame.QUIT:
    self.running = False
    self.playing = False

在主循环内实现了很多功能，文本窗口展示，血条展示，以及整个游戏循环的定义都是可以拿来借鉴的，我也是从油管主上学来的。

接下来，精灵类，包含玩家，敌人。子弹，地图四部分。

# color
 
black = (0, 0, 0)
white = (255, 255, 255)
red = (255, 0, 0)
green = (0, 255,0)
blue = (0, 0, 255)
yellow = ( 255,200,0)
purple = (128,138,135)

这个坦克大战还有一些小的bug，比如说，当你按下SPACE 开火是，第一发炮弹已经出去了，当你按下相反方向，子弹会按你第二次按下的方向移动。（不打算解决，开始学习游戏ai，和横板游戏的制作）

有想法的同学可以和我交流，欢迎大家留言。

最后，运行效果如下，双人操作 p1：w a s d space 开火 p2：上下左右 p 开火
