在游戏开发的过程中,很多时候需要策划填的一些静态数据表(比如英雄表,技能表等等),而策划一般都习惯使用excel。
excel在unity里面是不能直接读取的,所以我们一般要另存为txt读取,然后一行一行解析进行读取。
***.txt
id name price

但是有一点问题，策划改表是很频繁的，总不能每次策划改动我们另存为一次吧。
这个时候我们可以采用python写一个脚本动态批处理即可
how
1.安装mysql并且安装MySQLdb模块
测试环境win7 推荐python 编辑器pycharm
2.安装Navicat Premium导入excel表
3.配置读取参数
{
"db":{
"host":"127.0.0.1",
"user":"root",
"passwd":"",
"port":3306,
"db":"testdb"
},
"exp_sep":" ",
"exp_suffix":".txt",
"tables":[
"test_table"
],
"vos":[
"test_table"
]
}
4.动态生成txt和静态配置类
#! /usr/bin/env python
#coding:utf8
import sys
import MySQLdb
import json
reload(sys)
sys.setdefaultencoding('utf-8')
# tables = ('test_table',)
# vo = ('test_table',)
# ('test_table') is interpreted as using algebraic grouping and simply as max_price and not a tuple.
# Adding a comma, i.e. ('test_table',) forces it to make a tuple.

# description (('id', 3, 1, 11, 11, 0, 0), ('name', 253, 6, 765, 765, 0, 0), ('price', 4, 1, 12, 12, 31, 0))
def CreateCS(index, description):
vo = curconifg['vos']

my_cs.write(head)

my_cs.write(ctor_field % (curCol[0],ConvertCtorType(curCol[1]),colIndex))
my_cs.write(ctor_par2)
my_cs.write(class_part2)
def CreateConfig():
con = MySQLdb.connect(curconifg['db']['host'],curconifg['db']['user'],curconifg['db']['passwd'],curconifg['db']['db'],charset='utf8');
# notice ,charset='utf8'
with con:
cur = con.cursor()
tables = curconifg['tables']
for index in range(len(tables)):
table = tables[index]
# cur.execute("select * from %s where id = %s",('test_table',1))
# DB API requires you to pass in any parameters as a sequence
# but sql query is select * from \'test_table\' where id = 1
# like below error
# http://blog.xupeng.me/2013/09/25/mysqldb-args-processing
# so you can do it below,but not safe
query = 'select * from %s '%(table);
cur.execute(query)
with open('%s.txt'%(table),'w+') as my_txt:
# create file if not exits
description = cur.description
CreateCS(index,description)
# description (('id', 3, 1, 11, 11, 0, 0), ('name', 253, 6, 765, 765, 0, 0), ('price', 4, 1, 12, 12, 31, 0))
# create txt
line = curconifg['exp_sep'].join(str(curCol[0]) for curCol in description)
# id name price
my_txt.write(line+'
')
for i in range(cur.rowcount):
row = cur.fetchone()
line = curconifg['exp_sep'].join(str(col) for col in row)
# 1 张三 3.0
if(i <= (cur.rowcount - 1)):
my_txt.write(line+'
')
else:
my_txt.write(line)
with open("config.json","r") as jsonFile:
curconifg = json.load(jsonFile)
CreateConfig()
结果如图:
improvement
向上面那样考虑生成txt然后一行一行解析其实还是有点麻烦的,因为这个解析规则还是依赖于我们
其实我们可以考虑在生成的时候转换一下
***.txt
id name price
1 张三 3.0
{"id":1,"name":"张三","price":3.0}
是不是有很多想法啦，骚年！
