这篇文章将为大家详细讲解有关用Python制作坦克大战游戏，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。

小时候玩的“坦克大战”，你还记得吗？

环境依赖

python3.7

pygame1.9.6

urllib

内置库，如random、sys、time、os等

pygame介绍

Pygame被设计用来写游戏的python模块集合，基于SDL库开发。使用python可以导入pygame来开发具有全部特性的游戏和多媒体软件，Pygame是极度轻便的并且可以运行在几乎所有的平台和操作系统上。

1. 导入依赖 & 通用配置

importrandomimportsysimporttimefromurllib.requestimporturlretrieveimportosimportpygameSCREEN_WIDTH,SCREEN_HEIGHT=1200,700#画面大小MY_BIRTH_LEFT,MY_BIRTH_TOP=SCREEN_WIDTH/2,SCREEN_HEIGHT-60DIRECTION=[U,D,L,R]=[U,D,L,R]#控制键Tank_IMAGE_POSITION=rD:/tank_imgURL=https://gitee.com/tyoui/logo/raw/master/img/

2. 通用加载函数

#加载图片defload_img(name_img):save=Tank_IMAGE_POSITION+os.sep+name_img+.gififnotos.path.exists(save):urlretrieve(URL+name_img+.gif,save)returnpygame.image.load(save)#加载背景音乐defload_music(name_music):save=Tank_IMAGE_POSITION+os.sep+name_music+.wavifnotos.path.exists(save):urlretrieve(URL+name_music+.wav,save)pygame.mixer.music.load(save)pygame.mixer.music.play()

3. 通用基础类

*pygame.sprite模块，官方文档上说这个模块是轻量级的，在游戏开发中也未必要使用。*sprite翻译为精灵，在游戏动画一般是指一个独立运动的画面元素，在pygame中，就可以是一个带有图像（Surface）和大小位置（Rect）的对象。*pygame.sprite.Sprite是pygame精灵的基类，一般来说，需要写一个自己的精灵类继承一下它然后加入自己的代码。classBaseItem(pygame.sprite.Sprite):def__init__(self):super().__init__()

4. 定义bullet类

classBullet(BaseItem):#参数初始化def__init__(self,tank,window):super().__init__()self.direction=tank.directionself.speed=tank.speed*3self.img=load_img(bullet)self.rect=self.img.get_rect()self.window=windowself.live=Trueifself.direction==U:self.rect.left=tank.rect.left+tank.rect.width/2-self.rect.width/2self.rect.top=tank.rect.top-self.rect.heightelifself.direction==D:self.rect.left=tank.rect.left+tank.rect.width/2-self.rect.width/2self.rect.top=tank.rect.top+tank.rect.heightelifself.direction==L:self.rect.left=tank.rect.left-self.rect.width/2-self.rect.width/2self.rect.top=tank.rect.top+tank.rect.height/2-self.rect.height/2else:self.rect.left=tank.rect.left+tank.rect.widthself.rect.top=tank.rect.top+tank.rect.height/2-self.rect.height/2#子弹显示defdisplay_bullet(self):self.window.blit(self.img,self.rect)#通过按键控制子弹移动defbullet_move(self):ifself.direction==U:ifself.rect.top>0:self.rect.top-=self.speedreturnelifself.direction==D:ifself.rect.top<SCREEN_HEIGHT:self.rect.top+=self.speedreturnelifself.direction==L:ifself.rect.left>0:self.rect.left-=self.speedreturnelse:ifself.rect.left<SCREEN_WIDTH:self.rect.left+=self.speedreturnself.live=False#我方坦克子弹击中对方坦克defhit_enemy_tank(self):forenemyinTankGame.enemy_tank_list:hit=pygame.sprite.collide_rect(self,enemy)ifhit:self.live=Falseifenemy.click_count==1:enemy.live=FalsereturnNoneenemy.click_count-=1ifenemy.click_count==2:enemy.load_image=enemy.img32ifenemy.click_count==1:enemy.load_image=enemy.img31load_music(hit)#对方坦克子弹击中我方坦克defhit_my_tank(self,tank):hit=pygame.sprite.collide_rect(self,tank)ifhit:self.live=Falsetank.live=False#子弹击中围墙defbullet_collide_wall(self):forwallinTankGame.wall_list:result=pygame.sprite.collide_rect(self,wall)ifresult:self.live=Falseifwall.count==1:wall.live=Falseelse:load_music(hit)#子弹击中子弹defbullet_collide_bullet(self):forbulletinTankGame.enemy_bullet_list:ifpygame.sprite.collide_rect(bullet,self):bullet.live=Falseself.live=False

5. 定义tank类

classTank(BaseItem):#参数初始化def__init__(self,left,top,window,image,direction,speed):super().__init__()self.window=windowself.load_image=imageself.direction=directionself.img=self.load_image[self.direction]self.rect=self.img.get_rect()self.rect.left=leftself.rect.top=topself.speed=speedself.tank_width=self.rect.widthself.tank_height=self.rect.heightself.wall_switch=Falseself.move_stop=Trueself.live=Trueself.old_left=0self.old_top=0#开火deffire(self):returnBullet(self,self.window)#显示defdisplay(self):self.img=self.load_image[self.direction]self.window.blit(self.img,self.rect)defwall_not(self,direction):ifdirection==U:returnself.rect.top>0elifdirection==D:returnself.rect.top<=SCREEN_HEIGHT-self.tank_heightelifdirection==L:returnself.rect.left>0else:returnself.rect.left<=SCREEN_WIDTH-self.tank_widthdefwall_yes(self,direction):ifdirection==U:ifself.rect.top<0:self.rect.top=SCREEN_HEIGHTelifdirection==D:self.rect.top%=SCREEN_HEIGHTelifdirection==L:ifself.rect.left<0:self.rect.left=SCREEN_WIDTHelse:self.rect.left%=SCREEN_WIDTHdefmove(self,direction):self.old_left=self.rect.leftself.old_top=self.rect.topifself.wall_switch:self.wall_yes(direction)elifnotself.wall_not(direction):returnNoneifdirection==U:self.rect.top-=self.speedelifdirection==D:self.rect.top+=self.speedelifdirection==L:self.rect.left-=self.speedelse:self.rect.left+=self.speeddefstay(self):self.rect.left=self.old_leftself.rect.top=self.old_topdeftank_collide_wall(self):forwallinTankGame.wall_list:ifpygame.sprite.collide_rect(self,wall):self.stay()deftank_collide_tank(self):fortankinTankGame.enemy_tank_list:ifpygame.sprite.collide_rect(self,tank):self.stay()

6. 定义我方 & 对方tank类

classMyTank(Tank):def__init__(self,left,top,window):self.img=dict(U=load_img(p2tankU),D=load_img(p2tankD),L=load_img(p2tankL),R=load_img(p2tankR))self.my_tank_speed=4super().__init__(left,top,window,self.img,U,self.my_tank_speed)classEnemyTank(Tank):def__init__(self,left,top,window):self.img1=dict(U=load_img(enemy1U),D=load_img(enemy1D),L=load_img(enemy1L),R=load_img(enemy1R))self.img2=dict(U=load_img(enemy2U),D=load_img(enemy2D),L=load_img(enemy2L),R=load_img(enemy2R))self.img3=dict(U=load_img(enemy3U),D=load_img(enemy3D),L=load_img(enemy3L),R=load_img(enemy3R))self.img31=dict(U=load_img(enemy3U_1),D=load_img(enemy3D_1),L=load_img(enemy3L_1),R=load_img(enemy3R_1))self.img32=dict(U=load_img(enemy3U_2),D=load_img(enemy3D_2),L=load_img(enemy3L_2),R=load_img(enemy3R_2))#不同的坦克击中的次数不一样image,self.click_count,speed=random.choice([(self.img1,1,4),(self.img3,3,3),(self.img2,1,5)])super().__init__(left,top,window,image,self.random_direction(),speed)self.step=100@staticmethoddefrandom_direction():n=random.randint(0,3)returnDIRECTION[n]defrandom_move(self):ifself.step==0:self.direction=self.random_direction()self.step=random.randint(10,100)else:self.move(self.direction)self.step-=1defrandom_fire(self):ifrandom.randint(0,50)==1andlen(TankGame.enemy_bullet_list)<30:enemy_bullet=self.fire()TankGame.enemy_bullet_list.append(enemy_bullet)

7. 爆炸动作类

classExplode(BaseItem):def__init__(self,tank,window):super().__init__()self.img=[load_img(blast0),load_img(blast1),load_img(blast2),load_img(blast3),load_img(blast4),load_img(blast5),load_img(blast6)]self.rect=tank.rectself.stop=0self.window=windowself.rect.left=tank.rect.left-tank.rect.width/2defdisplay_explode(self):load_music(blast)whileself.stop<len(self.img):self.window.blit(self.img[self.stop],self.rect)self.stop+=1

8. 定义wall类
