DynEco
This plugin is beta. That means it may not work yet! DynEco is another plugin that determines prices for items/blocks on how much supply/demand there is for the item. It works by adding/removing a calculated amount from the default price determined in the config.
Features
- MySQL backend for logging. Each transaction is logged in an easy format. You can easily use this data for websites etc.
- Simple configuration, with 2 settings (plus MySQL settings) that allows you to have almost complete control over your prices.
- Price will increase as demand increases, and decrease as supply increases. See the equation at the bottom.
- Buy, sell and view current values with commands.
- Buy items with signs.
- Per-Block/item permissions system.
Dependancies
- MySQL server
- Vault
- An economy plugin supported by Vault. I recommend Essentials.
Installation
- Download: http://dev.bukkit.org/server-mods/dyneco/files/
- Extract and place the default config files and jar in the right directories.
- DON'T RUN SERVER
- Update config to match your MySQL database.
- Use the database.sql to generate the database schema. (Using PHPMyAdmin or something)
- Done!
Permissions
- dyneco.buy.* - Allow the group/user to buy any item.
- dyneco.buy.itemname - Allow the group/user to buy that item. itemname is the full name in lowercase with no spaces. E.G: diamondsword, or the item's ID.
- dyneco.sell.* - Allow the group/user to sell any item.
- dyneco.sell.itemname - Allow the group/user to sell that item.
Config
- multiplier: Use this value to change the amount of influence supply/demand has on the price. (Should be able to set to 0 for no influence at all)
- tax: A decimal value added to the total each time an item is bought. 0.15 = 15% etc. Set to 0 for no tax.
- span: Over how many days should supply/demand effect price.
How it works
Each transaction is logged in the MySQL database. When a player buys/sells an item it will count how many times it has been bought/sold over the last week. This data is then applied to the equation:
x = pad/100 * log(demand/supply)* k + k
Where demand is the total number of this item bought, and supply is the total number of the item sold. k is the default value of the item. log is a log to the base 10.
Oh and if you wanna do a pull request, go for it! https://github.com/ttocskcaj/DynEco
Coming Soon
- Enchantments - Buy enchantments for the item in your hand.

Yeah I suppose since all the data is available on mySQL, maybe you could even store the current prices on mySQL somehow? I could write a webpage to generate the list then. Otherwise an ingame list would be nice still.
Sorry about instant price updates, guess I didn't really test it properly.
Thanks for reading my bugs/suggestions, I'll continue testing updates of this, looks promising.

Sorry. Forgot to post that.
Same format as essentials economy signs, without the price at the bottom.
Dirt can be any common abbreviation, or an item ID.

It uses the official names from the Bukkit API. :p http://jd.bukkit.org/doxygen/d7/dd9/namespaceorg_1_1bukkit.html#ab7fa290bb19b9a830362aa88028ec80a
Simply make it lower case, and remove underscores. I will adapt it to use the item database from Essentials (That the buy/sell uses). That way you can enter any common abbreviation of a name, or an ID.

Yes groups would work fine also, but permission nodes for each item work the same in the end =)
Looking forward to future updates.
Oh and as a minor suggestion, I personally would prefer the permission nodes to be item id instead of item names, since everyone calls things different names.

Yea. The per-item permissions was a proof of concept thing that actually worked really well lol. I was thinking of having items grouped, so you could allow/deny certain groups. And of course the permissions will be available for selling as well

Posted Apr 27, 2012First dynamic economy to have permission nodes for buying a specific item, will definitely follow the updates to this. I'll download and test it tomorrow, about to head off to bed.
