Python+Pygame如何实现简单的射击小游戏

本文小编为大家详细介绍“Python+Pygame如何实现简单的射击小游戏”，内容详细，步骤清晰，细节处理妥当，希望这篇“Python+Pygame如何实现简单的射击小游戏”文章能帮助大家解决疑惑，下面跟着小编的思路慢慢深入，一起来学习新知识吧。

一、运行环境

1）环境安装

Python3、 Pycharm 、Pygame模块部分自带模块就不展示啦。

第三方库的安装：pip install pygame 或者

带镜像源 pip install -i https://pypi.douban.com/simple/ +模块名  

2）素材（图片、音乐等）

二、代码展示

主程序

import pygame,os,random
from pygame.locals import *
from pygame.sprite import *
def load_image(name):
    fullname=os.path.join(os.path.join(os.path.split(os.path.abspath(__file__))[0],"filedata"),name)
    image=pygame.image.load(fullname)
    return image
def load_sound(name):
    fullname=os.path.join(os.path.join(os.path.split(os.path.abspath(__file__))[0],"filedata"),name)
    sound=pygame.mixer.Sound(fullname)
    return sound
WIDTH=700
HEIGHT=600
class Explosion(Sprite):
    def __init__(self,screen,posrect):
        super(Explosion,self).__init__()
        self.screen=screen
        self.posrect=posrect
        self.image=load_image("explosion.png")
        self.rect=self.image.get_rect()
        self.rect=self.posrect
        self.rates=0
    def update(self):
        self.rates+=1
        if self.rates>=40:
            self.kill()
class Enemy(Sprite):
    def __init__(self,screen):
        super(Enemy,self).__init__()
        self.screen=screen
        self.screenrect=self.screen.get_rect()
        self.image=load_image("eatingfood.png")
        self.rect=self.image.get_rect()
        self.rect.center=(random.uniform(50,WIDTH-50),
                          random.uniform(50,HEIGHT-50))
        self.xspeed=random.uniform(1,2)
        self.yspeed=random.uniform(1,2)
        if random.choice([True,False]):
            self.xspeed=-self.xspeed
        if random.choice([True,False]):
            self.yspeed=-self.yspeed
    def update(self):
        self.rect.centerx+=self.xspeed
        self.rect.centery+=self.yspeed
        if self.rect.top>self.screenrect.height or self.rect.bottom<0:
            self.kill()
        elif self.rect.left>self.screenrect.width or self.rect.right<0:
            self.kill()
def initmain():
    pygame.init()
    screen=pygame.display.set_mode((WIDTH,HEIGHT))
    pygame.display.set_caption("")
    gameFont=pygame.font.SysFont("宋体",26,True)
    rates=0
    score=0
    fpstime=pygame.time.Clock()
    cursor=load_image("aimcursor.png")
    cursorrect=cursor.get_rect()
    pygame.mouse.set_visible(False)
    enemys=Group()
    explosions=Group()
    sou=load_sound("sou.mp3")
    duang=load_sound("duang.mp3")
    while True:
        fpstime.tick(70)
        screen.fill((128,128,128))
        screen.blit(gameFont.render("Score: "+str(score),True,(0,0,0)),(2,2))
        rates+=1
        enemys.draw(screen)
        enemys.update()
        explosions.draw(screen)
        explosions.update()
        if rates%25==0:
            enemys.add(Enemy(screen))
        cursorrect.center=pygame.mouse.get_pos()
        screen.blit(cursor,cursorrect)
        for event in pygame.event.get():
            if event.type==QUIT:
                pygame.quit()
                __import__("sys").exit()
            elif event.type==MOUSEBUTTONDOWN and event.button==1:
                cld=[]
                for sf in enemys:
                    if sf.rect.collidepoint(event.pos):
                        sf.kill()
                        score+=int(abs(sf.xspeed)+abs(sf.yspeed))
                        explosions.add(Explosion(screen,sf.rect.center))
                        cld.append(True)
                    else:
                        cld.append(False)
                if not any(cld):
                    sou.play()
                else:
                    duang.play()
        pygame.display.flip()
if __name__=="__main__":
    initmain()

三、效果展示

都是静态的截图展示，科能效果不是很好！动态的展示我就没录制视频了哈，大家拿代码自己玩儿哦~

1）游戏界面

2）击中效果

3）+3分
