Lockdown (Unofficial Port)

A port of the "Lockdown Reneoforged" mod by xiaofanwei123 for Neoforge 26.1.2

Lockdown is a mod designed specifically for modpacks, allowing you to control Minecraft’s world maps and dimensions, as well as whether the Singleplayer, Multiplayer buttons on the main menu and the buttons in the world creation screen are displayed. Through the configuration file, you can achieve the following:

• Preset World Template: Use a pre‑prepared save as a template; newly created worlds will be completely copied from the template.
• Fixed Dimension Copying: Copy only the data of specified dimensions (such as the Nether, End, or custom dimensions) from the template world, leaving dimensions not listed free to generate normally, while keeping already explored chunks in the configured dimensions fixed.
• Template Seed Inheritance: Make newly generated chunks in specified dimensions use the seed from the template world rather than the current world’s seed, ensuring consistent terrain for those dimensions across different worlds.
• Custom Spawn Point: Set a fixed initial spawn point and default respawn point for new players (dimension + coordinates + orientation), eliminating random world spawns.
• UI Simplification: Hide the “World” or “More” tabs in the world creation screen, and hide the “Singleplayer” or “Multiplayer” buttons on the main menu.

With the configuration file, you can achieve respawning at fixed coordinates in fixed dimensions on a fixed map, crafting a unique world by hand, and creating your own stories within it.
