Here's a video with an overview of some of DE's features, graciously made by WoopaGaming!
Plugin is in BETA - Meaning it is not as perfect as I would like as of yet. I am still constantly adding features. Once I'm happy with the feature list, it'll be released into v 1.0. Expect v1.0 to have Chest Shops.
Support Pages
There's a lot to understand about DynamicEconomy, so visit some of these helpful pages!
-
Features
- Buy and Sell items in a global shop.
- Price automatically adjusts based on supply and demand!
- Customizable price ceiling & floor!
- Prefix the chat output with anything you'd like!
- Choose whether price changes are announced globally, locally, or not at all!
- Includes a custom alias file, so you can customize the aliases you use (Add whatever word in the world to stand in for, say, diamond, so if you call /buy purpleelephant it can buy you diamond!) - Even better, it already includes hundreds of aliases.
- Add items to items.yml at your whim! Just make sure to add aliases for them in alias.yml!
- Sort items into different groups, and then limit users to only being able to purchase or sell items from particular groups!
- You choose the default amount sold/bought if the user leaves out the amount argument.
- Features 340 items: the most commonly traded and used, as well as non-obtainable items and potions!
- Also, you can sell and buy enchantments! Enchant your items with any enchantment at any level, and then sell items from an item instead of selling the entire item itself!
- Custom Items.yml puts you in control of item prices, minimums, maximums, descriptions, and everything else!
- Change the price, price floor, price ceiling, price velocity, and stock, all from in-game without a restart or reload!
- Custom in-game command allows you to reload the DynamicEconomy config.yml
- Features help screen of all commands, usages, and descriptions
- Assess which features of your config are on and off from in-game.
- Simple permissions: permission is the same as the command name.
- DynamicSign - Signs that show the price, stock, velocity, ceiling, or floor of any item in REAL TIME! You can also change the colors the sign displays in!
- Find out the durability of any item in your inventory, or your armor!
- When you sell a tool or armor, the price you receive is proportionate to how much of the durability was used up. If an item is 25% used up, a player will only get 75% of the total price when he sells it! Stops "Infinite tool" abuses.
- Update Checker & Downloader!
- Sell and buy EXP!
- Data values for all woods, wools, saplings, slabs, and inks!
- Option to use either set-amount item velocities, or a percent velocity.
- The option to turn on "Price-Decay-Over-Time", meaning, if items aren't purchased for a long time, their prices will decrease! This is fully customize-able to the last bit; customize percent of price decrease, what's considered a "long time", and how often to check for these items! Or disable it all-together!
- Also, in addition to price decay over time, there's also price inflation over time, so items that aren't sold for a while will have an increase in price! This encourages sale of those items!
- Multi-World support!
- /sell hand and /price hand for selling or checking price of the item you're holding!
- Ban items from in-game instantaneously!
- Customizable random events! Make your own wacky random events that change the prices of items!
- Customize standard DE messages! Up to 32 of them, currently!
- Use your own custom currency.
- Custom log.txt file personalizes logging of all user commands for very intuitive, useful, and helpful logs for Server admins. No need to fuss over confusing server logs and exceptions. (You can disable it, if you want, too!)
- Sales & Purchase Taxes!
- Set taxes from in-game!
- Extensive region control! Select your own 3D regions in which users can buy and sell items!
- Alternative commands for /buy and /sell, so you can use other popular economy plugins in conjunction!
- Basic location control, such as setting a minimum height from bedrock in order to access the economy.
- Loans! With custom payback times, minimum and maximum loans, as many loans as you'd like, and more!
- Dynamic Interest rates for loans!
- Ability to ban the sale OR purchase of certain items!

Nothing plugin the formula into excel with item names and variables cannot fix to make it easier to determine the set stock level for determined price.
I have to go back to work, if someone does not beat me i will make the excel/open office spread sheet with custom stock + 3 stocks predefined. As such Item Name | ID | Floor | Ceiling | Span | Custom Stock | Stock 1k | Stock 500 | Stock 0 | Price @ Custom Stock | Price @ 1k | Price @ 500 |Price @0
You will set the floor, ceiling, span, custom stock and the prices at those levels will auto calculate!

Posted Jun 19, 2012Is there a way to add stock to items? Like Armour, I like to make an armour shop but no one really sells armour, or tools. Maybe a nightly restock of certain items to a certain amount? So I can make sure there is atleast 1 suit in stock. Or 4 sets of tools. But wouldn't that make tools worth a ton if it's low on stock?

Haha great glad you like it.
Yeah that's one downside. However, it's a very, very good time investment.
Also, don't forget, change your STOCKS not your PRICES. Because if you set the prices for all the items, EnderEngine will just overwrite them because it uses the STOCK to determine the price. So you're going to want to increase or decrease stock to get it to around the price you want.

Posted Jun 18, 2012The region control is a little confusing. if I wanted to regulate people its kinda backwards if everyone has access to all the groups. I would like to not have the default as an "*" or please explain to me the way to setup. I would also like if the region inherited the ban item list globally initially so that way I could still control independantly, but I dont have to ban same crap over and over. Same with Taxes
So I create a region
I had to open the region config to remove the everything option to all groups. (reload the config)
Then I add the groups I want (back in game)
Now I am standing the the region and cannot buy the items I added. Weird cause /canibuy says I can but then I cannot buy when I try and buy. So i thought i had to add the groupto my user. But apparently i have access to that group already. so wonder what the deal is.

Posted Jun 18, 2012EnderEngine has arrived
EnderEngine is a revolutionary DynamicPricing Engine that will make dynamic price changing MUCH smoother.
In order to learn the ropes, I recommend you read the EnderEngine help page HERE
Here's the changelog for what's changed with the introduction of EnderEngine:
If you wish to generate the new config files, back up your DE directory, delete it, then restart your server and the new files will be generated.
