Verse codes for Unreal Engine

Hey i would like to ask how people make in verse code such good custom game settings e.g. for box pvp that the game just listens to it, i tried to do it myself but i am completely unable to cope with creating codes by myself anyone would like to help how to create such codes for UEFN??? because i am completely clueless and i am curious how it really works.

You can read documentation/tutorials to get started with verse and understand the basics

As Mineblo states, there are a lot of step-by-step tutorial Epic Games has. Also, you can search on You Tube and there are a few channels that have tutorials on how to get started with the basics.
My suggestion would be to start with something modest like the below tutorial, publish the entire game to get through the process, and then make another game with more and more features, and just keep repeating the process.
