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]-=10
if event.key == K_s:
myman[1]+=10
if event.key == K_a:
mydirection='left'
myman[0]-=10
if event.key == K_d:
mydirection='right'
myman[0]+=10
if 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]=10
if myman[0]>595:
myman[0]=595
if myman[1]<10:
myman[1]=10
if 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]=50
if mydirection=='left':
if mybgflag[0]==1:
screen.blit(man1b,myman)
mybgflag[0]=0
else:
screen.blit(man1a,myman)
mybgflag[0]=1
if mydirection=='right':
if mybgflag[0]==1:
screen.blit(man1b_back,myman)
mybgflag[0]=0
else:
screen.blit(man1a_back,myman)
mybgflag[0]=1
mybgflag[1]-=5
#2.上下跳动的动画
if mybgflag[3]==0:
mybgflag[3]=50
if mybgflag[2]==1:
myman[0]-=1.5
myman[1]+=1.5
mybgflag[2]=0
else:
myman[0]+=1.5
myman[1]-=1.5
mybgflag[2]=1
mybgflag[3]-=5
return 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:#top
enemysa.append([random.randint(30, 610),-35,40])

哈哈最终看一下游戏编译结果吧！有趣
哈哈，还不错哦，游戏就分享到这，需要源码的跟作者说一声！一家专门开发小游戏的苦逼作者
