Introduction

FlucShopPrices Params1.png

Does your gave have a live, ever-evolving market? Do the prices of items change over time depending on how your player influences the game? This plugin allows you to create fluctuating price systems via RPG Maker MZ's variable system. These variables are able to change factors such as the base price, the base padding, rates, and flat additions.

Features include all (but not limited to) the following:

  • Notetags that allow management of the base, plus, rate, and flat modifiers towards buy and/or sell prices.
  • JavaScript modifications for those who wish to finalize their calculations with a bit more control.
  • Determine if the sell version of the notetags are affected by the standard sell rate.

Requirements

This plugin is made for RPG Maker MZ. This will not work in other iterations of RPG Maker.


Tier 4

This plugin is a Tier 4 plugin. Place it under other plugins of lower tier value on your Plugin Manager list (ie: 0, 1, 2, 3, 4, 5).

This is to ensure that your plugins will have the best compatibility with the rest of the VisuStella MZ Plugin library.

Items and Equips Core VisuStella MZ

When using any notetags from Fluctuating Shop Prices, they will bypass any of the <Price: x>, <Sell Price: x>, and/or the JavaScript versions. That's because the fluctuating price notetags will take priority for better control and consistency.

---

Notetags

RPG Maker MZ's editor is unable to allow for custom traits/properties that a game dev may wish to associate with a database object, event, map, etc. Notetags are used to work around such limitations by allowing the game dev to tag certain traits/properties using specific Notetags declared by the related plugin.

Here is a list of Notetag(s) that you may use.


The following are notetags that have been added through this plugin. These notetags will not work with your game if this plugin is OFF or not present.

  - 'Sell' version of the notetag will only affect price when selling.
  - When selling, the base price is affected by the Sell Price Rate modifier
    if you decide to let it affect it. These settings can be altered in the
    Plugin Parameters.

  'base' price of this item, weapon, or armor.

---

<Price Plus Variable: x>
<Buy Plus Variable: x>
<Sell Plus Variable: x>

<Price Plus Variable: x, x, x>

  'plus' price of this item, weapon, or armor.
  - Insert multiple 'x' for more variables to contribute additively to the
    total 'plus' value amount when determining the price.
- By default, finalized prices will round up.

<Price Rate Variable: x>
<Buy Rate Variable: x>
<Sell Rate Variable: x>

<Price Plus Variable: x, x, x>

  'rate' price of this item, weapon, or armor.
  - Insert multiple 'x' for more variables to contribute multiplicatively to
