As I looked, the game is made on the RPGMaker_MZ engine. If I remember correctly, the scripts are written in Java. Although the engine itself makes it easier to work with basic tasks. But working with something more detailed is difficult. I'm trying to program a chest for my game myself, like in a Lona RPG. Of course, you can download the plugin, but it's paid, and I'm unemployed, so I'm trying to solve the issue myself. As a result, I was stuck on the output of the event inventory.😭
