Hi, thanks for the quick reply.

Makes a lot of sense.

Question/comment about the latest Dev release (0.974.1)

In src/main/java/utils/regalowl/hyperconomy/History.java

There are four places where the History sign result is "?"

in public synchronized String getPercentChange(HyperObject ho, int timevalue)

and in

 public synchronized HashMap<HyperObject, String> getPercentChange(String economy, int timevalue)

Your code returns the string "?" if
a) the handles ho or sr are null
b) if the getHistoricalValue() function returns a flag -1.0 (presumably a value to indicate no history)
c)  if if (historicValues.size() >= timevalue)  is false (line 238)
or d)  if   if (allValues.containsKey(ho)) {    is false, presumably if it cannot find a preset key identifying an object previously cached.

In any event .. four instances of cases where "?" is returned.  Same string, different rationale.

A suggestion is to alter the return string so there are four different return strings to pin point which is the rationale for no History data to be available ?

I'm trying to debug why I get "?"

I've checked the history table, and it's populated with multiple entries.

Eg.,

mysql> select object, count(*), min(price), max(price) from hyperconomy_history where object = 'ironingot' group by object having count(*) > 1;
+-----------+----------+------------+------------+
| object    | count(*) | min(price) | max(price) |
+-----------+----------+------------+------------+
| ironingot |        4 |    1129.49 |       1400 |
+-----------+----------+------------+------------+
1 row in set (0.00 sec)

My IronIngot History sign shows "(?)"

Ideas?

@RegalOwl

Cool man. Thanks.

Good luck. I will plug along and try to figure out what I can in the mean time.

Appreciate your hard work and enthusiasm towards the plugin. It shows.

More specific questions on HyperConomy dynamics.

So it says in the documentation (Basics page) "This basically means that the price of items will remain the same until the stock reaches a certain level."

How do I define the "certain level"? What is the unit of that quantity? Is it a scalar value of the item-quantity? item-price? something-else?

Next the Basic's page says:

"Once that stock level is reached, the item will transition to dynamic pricing mode and the price will start to change and react to supply and demand. Dynamic pricing mode is the standard pricing mode in which the price of an item changes every time it is bought or sold."

What exactly is the formula for "react" ? If it is a continuous function, what are the parameters? Is demand a quantity based on how many items are sold/bought by players over a given time period? Can I customize that period of time?

If a sign/transaction provides the capability to sell/buy 1 at a time vs. N at a time, does that difference factor into "demand?" (eg., a player dumps a stack of gold ingot at once.. vs selling one ingot every M minutes?)

Different topic:

So if a HyperConomy installation uses MySQL then there's at least two sets of data.

One set of data is in the tables stored in the RDMS and the other is stored in the filesystem (YML).

There are commands /importfrom... and /exportto... to move between the DB and the filesystem.

I find this very delicate in practice. To work with data in the filesystem (say edit with vi), I have to first flush any new items to the DB (/importnewitems default) then quickly /exporttoyml .. do my edits there in the files.

Then it gets tricky. I cannot "/hc disable" to and /import or /export. I have to have /hc enable{d} to do any /import or /export.

So after editing my files the filesystem, I do a /importfromyml and the DB gets loaded with the new values.. or does it.. It appears (from many testing runs) that this isn't always the case.

I've had to go into MySQL, and update the tables via SQL, then re-export / re-import until the files matched the DB (all the while the /hc is still enabled)

I could easily admit that I am not using the plugin correctly, but it also appears that the process of updating the database can quickly get wedged.

Ok the other source of data - the files themselves. (Assuming again that I'm enabling MySQL)

When hc is actually use ... when players are buying/selling, which database is actually being updated in real time? the files or the MySQL tables?

If the files are being updated in real time while sales/purchases occur even if MySQL is enabled, then the database in MySQL is getting stale.

If the DB is getting updated in realtime (and not the files) during purchases/sales then the files are getting stale.

I'm a bit nervous about this. There are commands like /ymladditem that touch the files first (even if MySQL is enabled).. so Now I have two sets of data, both with new data (possibly) that have to be reconciled upon... what event? the /importfrom... ? the /exportto...?

I'm an old-school SQL programmer so I'm not afraid of relational calculus.. Maybe you can draw up some words that explain exactly what's going on during

a) An instance of a purchase or sale when MySQL is enabled

b) An instance of /ymladditem when MySQL is enabled

c) An instance of /hc disable when MySQL is enabled

d) An instance of /hc enable when MySQL is enabled

Thanks very much.. message me directly if you wish to instead..

thanx (really like the plugin, lots to learn)

@D496580

OK that sounds fair. Thanks for updating the docs by the way. That _really_ helps isolate what to set for each command.

So.. here's a half question / half request .. Not sure where it falls --

It would be supremely cool to be able to show via signs what the current market price is of an item that is being bought by the server.

Eg. Here's a simple use case.

Server buys ingots from players. This is how we create the money (M1) supply (recall your Economics 101)

So the ingots are priced accordingly in the database and players sell their ingots, thus creating cash.

The cash in turn is used by players to trade among themselves for finished-goods (armor, tools, etc... The server does _not_ deal in finished goods, only raw basic commodities).

So, just like any exchange pit on Wall Street, it would be really sweet if a Sign could show the current ASK price of an item, like a "goldingot".

I could try to fake it with a "buy" transaction sign, but I don't know how to configure the sign to show the price. Maybe I'm doing it wrong.

Sort of unrelated pure question --

Tax rate. I want to set this and I'm not sure where. So, I looked in config.yml and found my answer.. Lot's of tax settings. I set them to what I wanted, then:

/hc disable /hc enable

thinking that would "reload" the config. The taxes didn't change. Did I do that wrong?

What is the right method to reload the plugin in such a way that config.yml for HyperConomy is truly reloaded?

Thanks, awesome plugin. I know there's more to this plugin I don't understand yet, but I will.

I forgot where it was, but is there a summary of the mathematics behind the formula of buying/selling prices? I have players wondering and I want to give them the straight answer from the top banana, or RegalOwl in this case.

Thanke.

@RegalOwl

Should enchanted items be able to be sold? As of .974.1 a woodenhoe with unbreaking (yeah, just testing) wouldn't sell as a wooden hoe. Didn't the enchant price used to be calculated and it would sell both the item and the enchantment?

I sent you a PM, but I don't think you saw it.

Hey again Regal, I have a question regarding custom economy options. I have changed my currency from dollars ($) to "SC Tokens" in Essentials, which changes the currency in just about everything except Hyperconomy. What I mean by this is that when a player purchases an item, the message "You bought 1.0 diamond for $500.0 of which $0.0 was tax" appears, when in fact I would like it to say "You bought 1.0 diamond for 500.0 SCT of which 0.0 SCT was tax."

So how would I change the prefix "$" to the suffix "SCT"?

(This is only a problem with the messages, not the actual event of a purchase within a shop)

Thanks, Erik.

Is there a way to enable /buy and /sell and what not globally not requiring the player to be insdie a defined shop?

@RegalOwl

Thank you much, with that and kommandsigns this is perfect :D

Is there a way to add enchanted, named items to the objects database without screwing up the base objects? I see that the database stores some metadata (like 5:3 for jungle wood) but it doesn't seem to be able to deal with additional metadata like named items (chainmail renamed to mithril and enchanted with projectile protection). Perhaps I have missed something. I tried using /ymladditem, but it only recognizes the base item (chainmail_chestplate).

It would be awesome to allow custom items to float through the various economies as well, although I realize this might be a substantial database re-write.

Hi, is there any way to create a shop with fixed price for all items and unlimited stock of those items? I have no idea how to do this, because the items.yml does not seem to have any correlation with the ingame settings.

So I have a request, I would love it if I could make server chest shops that had unlimited inventory. I see that you already have a feature planned to make it affect global stock which I would love, and having them tax would be good too.

Basically I'd like the chest shops to act as a gui to the server inventory

Thanks, the command line will be good for now but I dont have a very 'command friendly' server.

(Edit nevermind, found the answer right after posting this)

I hope this isn't a dumb question but I spent 10 mintues searching before commenting:

Is there a way to make a server chest shop?

(Also you should really put somewhere that you have to crouch to destroy chest shops)

Thanks for the great plug in, its the first I've seen one do exactly what I want without hours of work :)
