Using script calls with Yanfly's Event Copier

Hello,

Trying to figure out if it's possible through a simple script call to select one of five template events through RNG.

I have a chest event that has random items in it. When the player enters the map, I would like to generate a random number to a variable (1-10) and then use that variable to determine the quality of the items in the chest.

For example, a 1-5 would copy the event that uses the "common" pool for items, whereas a 6-9 would copy the event for "uncommon" items and a 10 would copy the event for "rare" items.

You might be thinking there's probably an easier way to do this than using this script in particular - I'm sure there is, but I wanted to use the event copier as it should make it simple not only for the sheer number of maps that I have but also that I change my mind a lot and I don't want to go back and edit 300 events every 2 days.

In a nutshell:

* Player enters map.
* Random number is generated to "ChestType" variable.
* Game checks variable against which template event to use.

Hope that makes sense. Seems like a simple script call would be able to do this.

Here is a link to Yanfly's Event Copier.

Thanks for any assistance in advance!
