ItemCommonParallel.js

When a common event is invoked from the menu screen, such as by using an item,
if the target trigger is "parallel processing," it will be executed in
parallel.
The switch specified as the trigger does not turn ON, but the specified common
event is executed in parallel processing only once.

If you invoke a common item from the menu screen while an event is running,
the event will be executed immediately.

@help ItemCommonParallel.js

アイテム使用などでメニュー画面からコモンイベントを呼び出したときに
対象のトリガーが「並列処理」の場合は、並列処理として実行します。
トリガーに指定したスイッチがONになるわけではなく、
指定したコモンイベントが1回だけ並列処理で実行されます。

イベント実行中にメニュー画面からアイテムコモンを実行した場合などに
即座にイベントが実行されるようになります。
