Economic Trinity
v1.8(core) / v2.3(factions) / v2.2(economy) / v1.5(currencies)
v1.8(core) / v2.3(factions) / v2.2(economy) / v1.5(currencies)
UPDATE (5/7/2026):
Uploaded newest demo! ( updated scripts and edited conversations to call proper plugin commands/scripts )
--
LvMZ_Core (v1.8) - Ensures MapManager.event() checks for any running event, also fixed $gameParty.extendActivate() to start from the character position (was returning wrong x,y coordinate)
--
LvMZ_Factions (v2.3)[final] - Fixed failsafe check on max lifespan, updated requirements, and fixed plugin commands. MAJOR: Fixed the Romance list (was missing characters making it invalid)
--
LvMZ_Economy (v2.2)[final] - Fixed issue with stolen item name/icon was not showing in inventory
--
LvMZ_Currencies (v1.5)[final] - Fixed Buy/Sell number (the price was being converted by the system twice returning the wrong value)
UPDATED (3/31/2026):
LvMZ_Core (v1.7) - Hotfix (skipTitle in Scene_Boot can't load from $gameSystem.. duh)
UPDATED (3/25/2026):
LvMZ_Core (v1.6)[final] - Added option to dynamically change "Skip Intro" option. Changed the
LvMZ_RemoteEvent class and how it handles data. Nothing left to alias (it auto-disables any parallel processing, movement, and auto-run events to prevent issues when setting up data of an event from another map).
--
LvMZ_Factions (v2.1)[final] - Code cleanup (update from 2.0 not required) - instructions clarify to use \\v[#] or \\a[#] if you want to use such text codes for faction,title,etc. names. Testing revealed one "\" would not be recognized properly. So use 2 or none...
--
LvMZ_Economy (v2.1)[final] - Had to revert shop supply & demand rate code. Was correct the first time *facepalm*
--
LvMZ_Currencies (v1.4)[final] - Code cleanup (to match the others in the set), itemType() moved to LvMZ_Core
UPDATED (3/24/2026):
LvMZ_Economy (v2.0) - Added "You:" text in party shop window for flavor, and more code cleanup
UPDATED (3/9/2026):
LvMZ_Economy (v1.91) - Hotfix (S&D object was calling an old code; has been updated now)
UPDATED (3/8/2026):
LvMZ_Factions (v2.0) - Updated for compatibility with LvMZ_Core v1.5
LvMZ_Economy (v1.9) - Added "Sold" icon for buyback items (core 1.5 compatible)
LvMZ_Currencies (v1.3) - Updated for compatibility with LvMZ_Core v1.5
UPDATED (3/6/2026):
LvMZ_Core (v1.5) - Major fix needed (function preventing Graphics initialization), plus added some new functions (ie $gamePlayer.activateEventXy) and did some more code cleanup
LvMZ_Core (v1.4) - Few function fixes and change to the params.value() method
UPDATED (1/14/2026):
LvMZ_Core (v1.3) - Fix for "CheckPermaDeath() function" (compile error)
UPDATED (12/22/2025):
LvMZ_Core (v1.1) - More naming functionality for the Game_Event class
LvMZ_Core (v1.2) - Fixed the Two Handed checks (you must have 2 States, one to add the Dual Wielder skill and one to Seal Equip (shield slot))
LvMZ_Factions (v1.9) - Fixed and adjusted a few age-related functions
UPDATED (10/30/2025):
LvMZ_Factions (v1.8) - Quick fix (forgot to put the default age and lifespan constants...)
UPDATED (10/26/2025):
LvMZ_Factions (v1.7) - Change a method name (getFactionHidden -> isFactionHidden), Overhaul on data handling plus other fixes, Minor convenience and syntax fixes, Added Romance options with Relations settings (to overhaul the FRS plugins), Added reputation(aka the "Fame" system), Age and Lifespan.
LvMZ_Economy (v1.8) - Updates to new LvMZ plugin formats + minor fixes with demo, Added a separate tracker for stolen gold and a method to clean it.
LvMZ_Currencies (v1.2) - A few fixes (including Alternate Currency tags using item names instead of numbers. Item name must match exactly (case-sensitive)! Updated to new format plus minor fixes for demo. (Newest Demo not yet uploaded)
UPDATED (08/09/2021):
LvMZ_Economy (v1.6) - Fixed the lack of accountability on a null/invalid item ($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_Core (1.8 or later required)
- LvMZ_Factions
- LvMZ_Economy
- LvMZ_Currencies
The Demo (google drive link): Download Demo
( finally updated! May 07 2026 )
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:
Usage:
It's better to follow the plugin instructions, as that would be too long to type out here.. In short however, Notetags..
