Prerequisites
Introduction to Modding Kit
Palworld Modding Kit allows you to utilize Unreal Editor to create various mods that interact with the game, be it editing values, calling in-game functions to make actions happen or creating entirely new content for the game.
Do note that this is an unofficial Modding Kit which means that you won't have access to the full game's code or content. It is meant to be a skeleton project for interfacing with the game's API.
It is recommended to have a basic understanding of Unreal Engine and how to use the Editor and Blueprints, because the basics apply to Unreal modding regardless of which game it is. The only thing that changes is the API you're using, which in this case is Palworld.
Prerequisites
You'll want to make sure you install all the prerequisites. If you skipped any steps, you will run into the "Pal could not be compiled" error once you launch the Modding Kit.
