[pre lang="javascript"]//=============================================================================
// MV全按鍵 版本2
// 最終更新：2016/4/15
//=============================================================================
/*:
* @plugindesc 全按鍵，解決您按鍵不夠的煩惱
* @author Q－S.T.
*
*
* @help 說明
* ＜使用方法＞在事件腳本或條件分歧的腳本欄使用以下語句：
* 判斷按著(Press)：InputEX.isPressed(鍵碼)
* 判斷按下(Trigger)：InputEX.isTriggered(鍵碼)
* 判斷長按(Repeat)：InputEX.isRepeated(鍵碼)
* 判斷長按2(LongPress)：InputEX.isLongPressed(鍵碼)
*
* ＜使用例＞
* InputEX.isPressed(13) // 按著Enter
* InputEX.isTriggered(71) // 按下G鍵
*
* ＜其他＞
* 1.長按2在預設用來做快轉事件用
* 2.腳本中附的鍵碼表供對照用
* 3.JS中ctrl、alt、shift沒分左右
* 4.判斷數字以外的字會改用預設方法
* 5.print screen(截圖鍵)無效，所以別用
* 6.Num Lock會重置按鍵判定，最好也別用
* 7.MV版本1.1.0後改成和Input關連
