Prefab Builder

Description

Here is a plugin for building prefabs in Adventure Mode. It allows you to place your prefabs in the world, hand over the resources, and gradually build your structure entirely in Adventure Mode without having to switch to Creative Mode. This is useful when playing on a Server.

How to Use

Open the Prefab Builder UI with:

/prefabbuilder Opens the main interface where all available prefabs are listed. You can select a prefab, adjust its position (temporary), hand over the required resources, and start the construction process.

/prefabimport Allows importing a Json/zip File via URL Download link from most major Filehosts
