Economic Trinity
v1.2 / v1.6 / v1.0
​

Spoiler: Change Logs

UPDATED (08/09/2021):
LvMZ_Economy (v1.6) - Fixed the lack of accountability on a null/invalid item ($gameParty.numItems()) when checking for the .stolen property.

UPDATED (07/4/2021):
LvMZ_Economy (v1.5) - Fixed the logStolenItem() function: The method of checking arrays didn't work so I implemented a function so it WILL work.

UPDATED (06/14/2021):
LvMZ_Economy (v1.4) - made it so demand names are actually case-insensitive (as instructed), fixed it so multiple <Demand: name> categories can be placed on an item for various regions (Warning: Because of the search behavior, if you have the exact same number of demands in the region as you do on the item, it will ONLY return the first found). Lastly - added in an adjustment rate for demands (fixed value) that can stack with - or be used independently of - the percentage rate!

LvMZ_Factions (v1.2) - Fixed small error with event conditions (wouldn't read the default ones if faction conditions were mixed in)
* Also Updating Demo (thieves guild hideout -> list of names (page 3 priority was "below character"; changed to "Same")

UPDATED (05/26/2021):
LvMZ_Factions (v1.1) - Included gender options (also configurable like everything else)
LVMZ_Economy (v1.3) - Lots of stuff, including:
* Individual shop funds (so they don't share the same startup if configured)
* Stores party inventory multiple times (if caught) instead of overriding each other! When retrieving gear, it returns the last stored gear set, until the array is empty.
* Can run an event when the shop is completely out of stock!
* Fixed the supplyCheck() method (wasn't calculating correctly)
* economicBuyPrice() and economicSellPrice() now take into account gender settings from LvMZ_Factions (if setup)

Come one, come all and liven up your worlds! I introduce to you a set of 3 plugins.
Plugin Order (github links for individual downloads):
- LvMZ_Factions
- LvMZ_Economy
- LvMZ_Currencies

The Demo (google drive link): Download Demo

Factions:
Introduce factions, races, relations, and titles to your world. This plugin provides a library of plugin commands and script calls for you to use to spice up your world. Want NPCs that react differently to you if you're of a different race or faction? Do you want to build up a relation with an NPC before you're able to... WooHoo?

This provides all of that! Of course, it only gives you the tools, you'll still have to do something with them.

Economy:
This plugin changes up shops, giving them a limited inventory, money, and adjusts prices based on "Regions" (not to be confused with RegionIDs) - districts, kingdoms, states, and so on with their own tax rates and "Demand" categories for items, weapons, and armors. If Factions is also included, it will adjust prices based on the parameters you set in there.

In addition, you can also steal items, sell stolen items, go to jail (have your equipment stored somewhere - like an evidence locker thematically, but really just stored on the party separately); restore or leave stolen items back where you found them, and more!

Currencies:
Inspired by the world's "Greatest Role-playing Game", you can create a currency set (Gold Pieces -> Silver Pieces -> Copper Pieces, or real world money, or anything really!) to use instead of the standard RPG Maker default currency unit. Of course this is optional.

There is also "Alternate Currencies" - variables, items, weapons, armors that you can use in substitution to buy something with, or to sell something for.

Screenshots:

Spoiler: Images

Usage:
It's better to follow the plugin instructions, as that would be too long to type out here.. In short however, Notetags..

The economy link goes to the currencies plugin.
Thanks for making them.

Ah so it did... fixed. Thank you for pointing that out

 

[lordvalinar]

Now updated LvMZ_Factions and LvMZ_Economy with some new features and fixes.

Can I change the sell price for diffrent Items? Like in Region A I get for Meat more Gold as in Region B?.

 

[lordvalinar]

Can I change the sell price for diffrent Items? Like in Region A I get for Meat more Gold as in Region B?.

Yes and no. You can setup a "Demand" in certain regions like "Meat", and then in the item notetag have:
<Demand: Meat>, then adjust its price percentage (1-100) to have it cost more.

You could do it with some JS (script call) - something that clones the item and then adjusts the cloned item like:

const item = JSON.parse(JSON.stringify($dataItems[id]));
item.price = // new price

That will leave the original database item alone and creates a working clone. Then make another script call to add the item to the shop goods after initialization. Like:

this.shop().addGoods(item, amount);

in the event command list
Note: To get a random amount of items you can use an array:

this.shop().addGoods(item, [2, 12]);

However, can't really change Alternate Currencies without extra work. Those are in the notetags, and I wouldn't recommend going into that mess lol

@Kentaro_
Good news. Had some things to fix anyways, so I added a demand adjustment (fixed rate) for items by region demands (What you were asking for basically). Now you just put in the fixed adjustment in the parameters and ensure the item has that <Demand: name> tag!

This is the kind of plugin where I dont need it for my current project, but i want to make a whole new game just to use it xD

Or perhaps it's the kind of plugin(s) that you do need, but never knew that you needed it

 

[Willibab]

Dont tempt me xD Trying to keep things simple! Its harder then i imagined it would be ^^

 

[lordvalinar]

Well either way... should hold off from downloading them in the next hour or so anyways. I keep finding mistakes, or things to fix (like the removeTitle() function was not removing the proper title.) *sighs* I think this is the last fix though. Then the Demo and all plugins should be properly updated (Except Currencies... that one seems fine) lol

 

[Kentaro_]

That's really amazing. Thank you

 

[TrentL111]

Love that you can set a max number of items to buy. That's super cool

So I got this error when unequipping, an item.

The only other plugins I'm using are Viz Core and Items and Equips.

Turns out I forgot to account for a null/invalid item (when searching for the stolen property) For an instant fix, add:

if (!item) return 0;

right above the "const num = gameParty_numItems.call(this, item);" line (913-914 or so).

I'll have the script updated and uploaded momentarily

Thank you!

Hi, this looks neat, could the faction plugin be used for tracking variables kinda like a reputation system for the factions?

For what I’ve seen, yes it can. It might not be as straightforward as you describe, but I think it could work with the relationship system in the faction plug-in.

EDIT: Yeah what BeanCanDev said

You wouldn't necessarily need the factions plugin for that. The Factions plugin (for faction-specific interaction is more based on prices in Economy. Although technically speaking you COULD setup the Relations data to be more faction oriented rather than friendship/lovers (and then use my Friendship-Romance System plugin instead! - sorry had to plug xD).

That way the Relations data could be based on each faction.. what I mean is it's all name-based.
Relation[Jets] = 90 (friendly)
Relation[Sharks] = 0 (hostile)

for example. (also hope someone got the reference xD)

Thanks for making these plugins!! I am currently using Currencies, but for an upgrade system using the shop. Basically an upgraded version of "Staff" ("Enchanted Staff") is being sold for the price of: Staff and a Crystal. This works really well.

What I'd like is for the plugin to see if "Staff" is currently equipped or not, and take the equipped item as currency if it is equipped. This way the user doesn't need to unequip their weapons before going up to the shop to upgrade.

I don't know javascript but I see this:

Game_Party.prototype.gainItem = function(item, amount, includeEquip)

and I think "includeEquip" should be "true" for this to work the way I'd like? Maybe? Haha.

Anyway, I was wondering if you could make this an option, maybe to turn on in the parameters! Thanks so much
