Prefab
by Brian-Wuest
With Prefab, players place ready-made houses and structures into a world at once, instead of building them by hand or waiting for a generated village.
What it does
Prefab provides items that generate buildings automatically at a chosen spot. Before placing a structure, a preview button in each structure GUI creates a shadow copy in the world, so the builder can check the space available and the placement. Real-time movement through the projection is part of the same preview. Some block facings, such as those of fences and torches, may look wrong in the preview but are correct once placed.
The mod is aimed at survival and creative worlds, and at multiplayer servers where a builder wants finished buildings without clearing ground or defending work from creepers. Structures are limited to the set that ships with the mod, and it uses vanilla blocks or blocks added by the mod. The author notes that custom blueprint loading is not planned and points to Structurize for that job.
Prefab requires Cloth Config API. Mod Menu is optional and adds a settings screen. Files are published for Fabric, Forge and NeoForge, and the mod runs on client and server, so the server and every player need it. The code is under the MIT License and is open source.
