How to Use
--------------------------------------------------------------------
Writing
<HitFormula:xxx>
in the memo for an item or skill will set the hit formula to xxx.
In addition to the a, b, and v options available in the standard damage formula, xxx can also use hit (the actor's hit value) and eva (the target's evasion value - magic evasion value if using magic).

Writing
<EvaFormula:xxx>
in the memo for an item or skill will set the evasion formula to xxx.
In addition to the a, b, and v options available in the standard damage formula, xxx can also use hit (the actor's hit value) and eva (the target's evasion value (magic evasion value if using magic)).

For items and skills that do not have a specific formula set, the formula used in the parameters will be used.

As of version 1.01, a multiple-threshold determination mechanism has been added.
Entering either
<JudgeCount:○>
in the skill or item memo will cause the system to make that many judgments during hit detection.

If any of the hits are successful, it's a hit. If all hits are avoided, it's an evasion.

You can access the hit count with b.hc().

Update History:
ver1.01:
Terms of Use changed to the MIT License.
Added a mechanism for counting the number of judgments.
ver1.00:
Released

@param HitFormula
@desc This is the basic formula for calculating hits.
@default hit - eva

@param EvaFormula
@desc This is the basic formula for avoidance calculation.
@default 0

@param HitCountMessage
@desc This is a message about the number of hits of the attack. Change _cnt to the number of hits and _name to the name.
@default _cnt hits!

使用方法
------------------------------------------------------
アイテムやスキルのメモに、
<命中計算式:xxx>
または、
<HitFormula:xxx>
と記述すると、命中の計算式がxxxに設定されます。
xxxでは、通常のダメージ計算式で使用できるa,b,vに加え、
hit(行動者の命中値),eva(対象の回避値-魔法なら魔法回避値)が使用可能です。

アイテムやスキルのメモに
<回避計算式:xxx>
または、
<EvaFormula:xxx>
と記述すると、回避の計算式がxxxに設定されます。
xxxでは、通常のダメージ計算式で使用できるa,b,vに加え、
hit(行動者の命中値),eva(対象の回避値(魔法なら魔法回避値))が使用可能です。

個別で式が設定されていないアイテムやスキルは、パラメータで使用された式が設定されます。

ver1.01より、複数回判定の仕組みを追加しました。
スキルやアイテムのメモに
<判定回数:○>
<JudgeCount:○>
のいずれかを記述すると、命中判定時に回数分の判定を行います。
そのいずれかで命中すれば命中となり、命中した分をすべて回避すれば回避となります。
命中回数にはb.hc()でアクセス可能です。
