-----

Normally, when entering a state with action restrictions, the TPB gauge is
reset.
This plugin allows you to create states that do not reset.

State Memo
<RestrictedKeepTpb:[ratio]> States with this tag will not have their TPB
reset.
[ratio]: TPB change ratio when added *Optional
<RestrictedKeepTpb> Disables initialization
<RestrictedKeepTpb:50> Reduces the current TPB to 50%. If multiple TPBs are
added, the TPB is multiplied.

@plugindesc 行動制限TPB初期化無効ステート
@author NUUN

@help
通常は行動制限があるステートにかかると、TPBゲージが初期化してしまいます。
このプラグインでは初期化されないステートを作ることができます。

ステートのメモ欄
<RestrictedKeepTpb:[ratio]> このタグがあるステートはTPBが初期化されません。
[ratio]:付加時のTPB変化割合 ※省略可能
<RestrictedKeepTpb> 初期化無効
<RestrictedKeepTpb:50> 現TPBの50%に減少 複数の場合はさらに乗算
