This is a mod to add a way to add content to the game, including blocks, items, and events. It is intended for use by modpack developers, and does nothing out of the box.
It adds a folder in the Minecraft directory called "gameobjects". Create a JSON file in there with any name you'd like and add entries matching the format.
