Sharing this here as well (copy/paste from Modcraft)

Hi guys!

Took me some time to post this because I couldn't find any fan for my laptop.... But I did some days ago so... Here you go!

As I said before, I acknowledge this is not much. But I just wanna play my part in Modcraft  as best as I can even if it doesn't mean a lot.

First you will need the tables and rows which the script uses : SQL File

Then the Creature Script : StockExchange.cpp

/*
1.0.0
StockExchange NPC Script
Description
-----------
The script uses data from DB to define 5 different stocks (Name, Worth (in gold coins), Scale (scale of the stock's variations), OwnedRatio(so that players can't acquire more than its worth)).
Players can buy and sell shares of those stocks, provided they have bought a licence first.

Thanks to Rochet2 for the nice menu look and for helping me clean this script up!

I know this code ain't perfect but I'm still open for suggestions and critics.

嗨，大家好！

花了我一些时间发布此消息，因为我找不到笔记本电脑的风扇。...但是几天前我这样做了，所以...来了！

如我之前所说，我承认这一点并不多。但是我只是想尽我最大的努力在Modcraft中发挥作用，即使这并不意味着什么。

首先，您将需要脚本使用的表和行：SQL File

然后创建生物脚本：StockExchange.cpp

/* 1.0.0 StockExchange NPC Script Description ----------- The script uses data from DB to define 5 different stocks (Name, Worth (in gold coins), Scale (scale of the stock's variations), OwnedRatio(so that players can't acquire more than its worth)). Players can buy and sell shares of those stocks, provided they have bought a licence first. Thanks to Rochet2 for the nice menu look and for helping me clean this script up!   */ #include "ScriptPCH.h" #include "Config.h" #include "ScriptedCreature.h" #include "Language.h" #include "time.h" #define STOCKNUMBER 5 #define GOLDTOCOPPER 10000 namespace {     class CS_StockExchange : public CreatureScript     {     public:         CS_StockExchange() : CreatureScript("Creature_StockExchange") { }                  uint32 stock = 0;
