[python] 开发小游戏豆豆吃花瓣

今天来做一个python游戏

使用python的游戏框架pygame开开发一个自创的豆豆吃花瓣的游戏【还没有取名字？】

首先看下游戏主目录下有些什么文件

就一个img的文件夹，和一个py的文件

img文件夹下有这几个用photoshop做好的图片资源，还有中文字体

打开sublime文本开发软件，写入最开始的游戏框架

#-*- coding:utf-8  -*-
import pygame
from pygame.locals import *
import random
from random import randint
import time
from sys import exit
pygame.init()
def main():SCREEN_SIZE = [640,480]screen=pygame.display.set_mode(SCREEN_SIZE,0,32)title=pygame.display.set_caption('Delicious')pygame.display.flip() #刷新界面while True:for event in pygame.event.get():if event.type == pygame.QUIT:exit()screen.fill([0,0,0]) #填充平面为黑色背景pygame.display.update()#游戏更新if  __name__ == '__main__':main()

输出结果如下图：

出现了一个黑色背景的框框
这就证明游戏搭建成功了！

现在普及下pygame游戏中的各种方法：
screen = pygame.display.set_mode([640,480]) #创建一个窗口框640，高480
bg = pygame.image.load(‘bg.png’) #载入为bg的图片转换为平面变量bg
screen.blit(bg,(0,0)) #绘制一个为bg的图片平面
mysecond_font=pygame.font.Font(“img/poster.ttf”,35) #载入字体，字号为35px
screen.fill([0,0,0]) #将屏幕填充为黑色[三个255也就是白色，使用的rgb填充]

#这里是循环轮播事件检测 有按键 鼠标 等等事件
for event in pygame.event.get():if event.type == pygame.QUIT:exit()if event.type == KEYDOWN:if event.key == K_w:myman[1]-=10if event.key == K_s:myman[1]+=10if event.key == K_a:mydirection='left'myman[0]-=10if event.key == K_d:mydirection='right'myman[0]+=10if event.type == KEYUP:pass

这里是引用

#用来左右方向的壁纸切换
def screenblit():#吃货左右状态绘制if mydirection=='left':screen.blit(man1a,myman)if mydirection=='right':screen.blit(man1a_back,myman)#这是角色上下左右的位置越墙检测
def overwall():if myman[0]<10:myman[0]=10if myman[0]>595:myman[0]=595if myman[1]<10:myman[1]=10if myman[1]>435:myman[1]=435

但是在pygame框架中，很多动画都需要自己写，设置刷新都需要自己做，不过难不倒作者啦我做了一个切换角色样貌的demo如下函数

def blit_animation(mybgflag,myman):#1.嘴巴动的动画if mybgflag[1]==0:mybgflag[1]=50if mydirection=='left':if mybgflag[0]==1:screen.blit(man1b,myman)mybgflag[0]=0else:screen.blit(man1a,myman)mybgflag[0]=1if mydirection=='right':if mybgflag[0]==1:screen.blit(man1b_back,myman)mybgflag[0]=0else:screen.blit(man1a_back,myman)mybgflag[0]=1mybgflag[1]-=5#2.上下跳动的动画if mybgflag[3]==0:mybgflag[3]=50if mybgflag[2]==1:myman[0]-=1.5myman[1]+=1.5mybgflag[2]=0else:myman[0]+=1.5myman[1]-=1.5mybgflag[2]=1mybgflag[3]-=5return mybgflag,myman#最后返回

#接下来就需要创建怪物了哦！

def createenemys(enemytimers,enemysa,enemyseveral):#创建怪物if enemytimers==0 and enemyseveral>0: #之创建5个怪物print 'create-enemy'enemyrand=random.randint(1, 8)if enemyrand==1 or enemyrand == 3:#topenemysa.append([random.randint(30, 610),-35,40])elif enemyrand==2 or enemyrand == 4:#downenemysa.append([random.randint(30, 610),515,40])elif enemyrand==5 or enemyrand == 7:#leftenemysa.append([-35,random.randint(30, 610),40])elif enemyrand==6 or enemyrand == 8:#rightenemysa.append([675,random.randint(30, 610),40])enemytimers=100enemyseveral-=1enemytimers-=5for enemy in enemysa:#怪物随机移动if enemy[1]<0:enemy[1]+=1else:if enemy[2]==0:enemy[2]=40enemydirection=random.randint(1, 45000)if enemydirection>0 and enemydirection<10000:#topenemy[1]-=2for i in range(random.randint(5, 10)):enemy[1]-=3elif enemydirection>=11000 and enemydirection<20000:#downenemy[1]+=3for i in range(random.randint(5, 10)):enemy[1]+=3elif enemydirection>=21000 and enemydirection<30000:#leftenemy[0]-=3for i in range(random.randint(5, 10)):enemy[0]-=3elif enemydirection>=31000 and enemydirection<=40000:#rightenemy[0]+=3for i in range(random.randint(5, 10)):enemy[0]+=3elif enemydirection>40000 and enemydirection<=45000:#nonepassenemy[2]-=5for enemy in enemysa:#怪物的越界if enemy[0]<10:enemy[0]=10if enemy[0]>595:enemy[0]=595if enemy[1]<10:enemy[1]=10if enemy[1]>435:enemy[1]=435for enemy in enemysa:  #绘制怪物screen.blit(enemysaimg,(enemy[0],enemy[1]))return enemytimers,enemysa,enemyseveral#最后返回

def createfoods(food1,food1s,foodserverl):if foodserverl:print 'food'food1s.append((random.randint(10, 615),random.randint(10, 445)))foodserverl-=1if foodserverl==0 and len(food1s)==0:foodserverl=random.randint(1, 5)for food in food1s:screen.blit(food1,food)return food1,food1s,foodserverl#最后返回

 #我是否吃到了食物def eachcheck(myman,enemysa,food1s,myblood,score):#我和食物的碰撞foodn=0for food in food1s:if myman[0]+30>food[0] and myman[0]<food[0]+25:if myman[1]+30>food[1] and myman[1]<food[1]+25:print 'MY AND FOOD'food1s.pop(foodn) if score>=0:score+=random.randint(1, 5)#吃到一个小花加分1-5  foodn+=1for enemy in enemysa:#怪物和我的碰撞if myman[0]+30>enemy[0] and myman[0]<enemy[0]+30:if myman[1]+30>enemy[1] and myman[1]<enemy[1]+30:print 'I AND ENEMY'if myblood>=0:myblood-=1#我的血扣for food in food1s:#我是吃到到了食物if myman[0]+30>food[0] and myman[0]<food[0]+25:if myman[1]+30>food[1] and myman[1]<food[1]+25:print 'I AND FOOD'for enemy in enemysa:#怪物和食物的碰撞foodn=0for food in food1s:if enemy[0]+30>food[0] and enemy[0]<food[0]+25:if enemy[1]+30>food[1] and enemy[1]<food[1]+25:print 'ENEMY AND FOOD'food1s.pop(foodn)myblood-=5foodn+=1return myman,enemysa,food1s,myblood,score

#接下来就是绘制角色的血量游戏的输赢界面和游戏中有60秒倒计时的功能如下：

def blitmyblood(myblood,myblood_surface,score):screen.blit(myblood_surface,[5,0])screen.blit(myscore_surface,[450,0])bloodbordor=pygame.draw.rect(screen,[0,0,0],[60,5,200,15],2)bloodvalue=pygame.draw.rect(screen,[255,255,0],[62,7,myblood,12])myscoretts_surface=myscore_font.render('%s'%score,True,(0,0,255))screen.blit(myscoretts_surface,[535,0])second_surface=mysecond_font.render('%s'%gamesecond,True,(255,255,0))screen.blit(second_surface,[0,440])return myblood,myblood_surface,scoredef GameOver(myblood,gameoverwindows,myman):if myblood<=0:screen.blit(gameoverbg2,[0,0])gameoverwindows=1return gameoverwindows,mymandef GameVictory(myblood,score,gamesecond):if myblood>0 and gamesecond<=0 and score>=100:screen.blit(victorybg,[0,0])return myblood,score,gameseconddef gametimes(timeflag,gamesecond):if timeflag==20:if gamesecond>0:gamesecond-=1timeflag=0timeflag+=1return timeflag,gamesecond

哈哈最终看一下游戏编译结果吧！有趣
