Hey again, it's me. I was wondering how would I make a chest open revealing an item that you get in your inventory (Also, how do I make an inventory in my menu) like in The Sully Chronicles?

I really couldn't understand your question. Are you asking this for a specific game?

In order to have an inventory system, you need to code it. Every system is different. If you want one similar to Sully, and using Verge, I think the easiest way is borrowing the code from there.

But basically: you have some sort of array with your items, and an array with flags, that indicate whether a chest has already being found. Then when the party finds a new chest, you mark the flag as true, and add the item to the inventory array.
