PartyAbilityRate.js

You can define a "party ability" with a specified rate.
This function works regardless of the "party ability" feature.
Please set the following in the database memo field (※).
*Actor, Class, Weapon, Armor, State

// Encounter rate is quadrupled.
<Encounter Rate: 4>
<EncounterRate: 4>

// Preemptive attack rate is eight times higher.
<Preemptive Attack Rate: 8>
<PreemptiveRate: 8>

// Money earned is 0.5 times higher.
<Money Earned Rate: 0.5>
<GoldRate: 0.5>

// Item acquisition rate is quadrupled.
<Item Drop Rate: 4>
<DropItemRate: 4>

If multiple rates overlap, the highest number takes precedence.

This plugin requires the base plugin "PluginCommonBase.js."
"PluginCommonBase.js" is located in the following folder under the RPG Maker
MZ installation folder:

dlc/BasicResources/plugins/official

@help PartyAbilityRate.js

レートを指定した『パーティ能力』を定義できます。
特徴『パーティ能力』とは無関係に動作します。
データベースのメモ欄(※)に以下の通り設定してください。
※アクター、職業、武器、防具、ステート

// エンカウント率が4倍になります
<エンカウント率:4>
<EncounterRate:4>

// 先制攻撃の確率が8倍になります。
<先制攻撃率:8>
<PreemptiveRate:8>

// 獲得金額が0.5倍になります。
<獲得金額率:0.5>
<GoldRate:0.5>

// アイテム入手確率が4倍になります。
<アイテム入手率:4>
<DropItemRate:4>

複数のレートが重複した場合はもっとも数字の大きいものが優先されます。

このプラグインの利用にはベースプラグイン『PluginCommonBase.js』が必要です。
『PluginCommonBase.js』は、RPGツクールMZのインストールフォルダ配下の
以下のフォルダに格納されています。
