This scriptlet is very practical. It allows you to predefine a message that will include both the object's name and the total amount of things the party has gain or lost just a split second ago. You will no longer need to click on the Show Text event command ever again to inform the player about those changes.
That's laziness at its best!
NOTES:
The FOUND_MSG & LOST_MSG constants contain the automated earn & lost messages. Feel free to change them at will.
Yet, you can also customize both JOIN_MSG and LEAVE_MSG if you want to add your touch to this new automated message.
I know VX & VX ACE already offer a way to quickly create a automated message, yet, this one allows you to find several items in a row at the same spot without any complications. And you can still add any other event commands to your event command list.
