-----------------------------------------------------------------------------
Overview
-----------------------------------------------------------------------------
By implementing this plugin, you can set skill cost consumption in more detail.

This plugin is an extension plugin for FTKR_ExItemConfig_ItemBasic.js.

-----------------------------------------------------------------------------
Setup Instructions
-----------------------------------------------------------------------------
1. Add this plugin to the "Plugin Manager."

2. This plugin requires FTKR_ExItemConfig_ItemBasic.js.

3. This plugin cannot be used in conjunction with FTKR_SkillExpansion.js.

-----------------------------------------------------------------------------
Usage Conditions
-----------------------------------------------------------------------------
You can set skill cost consumption by adding the following note tag to the skill.
Cost consumption can be set for each data ID in FTKR_ExItemConfig_ItemBasic.js.

<EIC COST: x>
code
</EIC COST>
: Registers the code setting for data ID x.

[Items that can be used in code]
Mp: eval
: Changes MP cost to the value set by eval.
Tp: eval
: Changes TP cost to the value set by eval.
Hp: eval
: Sets HP cost to the value set by eval.

[About the Value of the Calculation Formula (eval)]
Like damage calculation formulas, the calculation formula (eval) allows you to use non-fixed values by entering a formula.
The following codes can be used:
a.param - References the user's parameters. (a.atk is the user's attack power)
s[x] - References the state of switch ID x.
v[x] - References the value of variable ID x.
iv[x] - References the value of item self variable ID x. (*1)

(*1) FTKR_ItemSelfVariables.js is required to use self variables.

Input Example)
Consume all of the user's current MP and TP.
However, at least 1 is required.
<EIC COST: 0>
Mp: Math.max(a.mp, 1)
Tp: Math.max(a.tp, 1)
</EIC COST>

-----------------------------------------------------------------------------
概要
-----------------------------------------------------------------------------
本プラグインを実装することで、スキルの消費コストをより詳細に設定できます。

本プラグインは、FTKR_ExItemConfig_ItemBasic.jsの拡張プラグインです。


-----------------------------------------------------------------------------
設定方法
-----------------------------------------------------------------------------
1.「プラグインマネージャー(プラグイン管理)」に、本プラグインを追加して
   ください。

2. 本プラグインには、FTKR_ExItemConfig_ItemBasic.js が必要です。

3. 本プラグインは、FTKR_SkillExpansion.jsと組み合わせて使用できません。


-----------------------------------------------------------------------------
使用条件の設定
-----------------------------------------------------------------------------
スキルに以下のノートタグを追記することで、消費コストの設定ができます。
消費コストはFTKR_ExItemConfig_ItemBasic.jsのデータID毎に設定できます。

<EIC コスト: x>
code
</EIC コスト>
   :データID x に対して code部の設定を登録します。

[code に使用できる項目]
Mp: eval
   :消費MPを eval で設定した値に変更します。
Tp: eval
   :消費TPを eval で設定した値に変更します。
Hp: eval
   :消費HPを eval で設定した値にします。


[計算式(eval) の値について]
計算式(eval)は、ダメージ計算式のように、計算式を入力することで、
固定値以外の値を使用することができます。以下のコードを使用できます。
 a.param - 使用者のパラメータを参照します。(a.atk で使用者の攻撃力)
 s[x]    - スイッチID x の状態を参照します。
 v[x]    - 変数ID x の値を参照します。
 iv[x]   - アイテムのセルフ変数ID x の値を参照します。(*1)

(*1) セルフ変数を使用する場合は、FTKR_ItemSelfVariables.jsが必要です。


入力例）
使用者の現在MPと現在TPをすべて消費する。
ただし、最低1は必要とする。
<EIC コスト: 0>
Mp: Math.max(a.mp, 1)
Tp: Math.max(a.tp, 1)
</EIC コスト>
