ITEM.VIPONLY = true/false

[excuse me if I’ll make some grammatical error, Im ITALIAN]
I want to add weapons for vip in my servers, can it?
I saw that when you add in PointShop, a weapon, you write ITEM.AdminOnly = true / false.
you can do a similar, but instead of (admin) insert VIP?: EXAMPLE: ITEM.VIPOnly = true / false

Look at how AdminOnly is done, read through the code and try to understand how it works, before modifying it to suit your own needs.
