Default World Generator (port): Lock World Type for Modpacks
In modded Minecraft, a single misclick during world creation can unravel hours of careful design. The Default World Generator (port): Lock World Type for Modpacks mod eliminates that risk by letting pack authors enforce exact world generation rules. From the world type and seed to structure toggles and startup commands, every parameter is locked down for a consistent player experience.
What This Mod Does
Originally a port of a classic 1.7.10 utility, this tool has evolved into a full-featured configuration suite for modern Forge environments. It intercepts the world creation screen and applies your predefined presets. You can offer players a choice of approved world types or hide the selection entirely, forcing a single default. The mod also handles seed binding, structure generation, bonus chest settings, and automatic datapack loading—all from a centralized config.
Key Features at a Glance
- World Type Lock: Set the default world type (default, superflat, custom modded types) and prevent accidental changes.
- Seed Management: Tie a fixed seed to a world type to maintain chunk alignment with pre-generated content.
- Structure Toggle: Force structures on or off globally, overriding other mods’ settings.
- Startup Commands: Run commands on world load to set gamerules, trigger functions, or configure server rules.
- Datapack Sync: Store datapacks in the mod’s config folder; they automatically apply to new saves and update with the pack.
- Bonus Chest Control: Enable or disable the bonus chest by default.
- Pack Mode Integration: On supported versions, link presets to CraftTweaker’s Pack Mode for advanced conditional setups.
How to Install and Use
To download Default World Generator (port): Lock World Type for Modpacks, get the JAR file from CurseForge or Modrinth and drop it into your Forge mods folder. The mod supports a wide range of Minecraft versions, including 1.7.10, 1.8.9, 1.9 through 1.11, 1.12, and newer releases. For a hassle-free setup, launchers like foxygame.net let you install the mod directly from their interface, keeping your instance clean and up to date.
Once installed, configuration for version 2.0+ is entirely in-game:
- Launch the game and reach the main menu.
- Open the Mods list, locate Default World Generator, and click Configure.
- In the preset editor, create a new profile. Set the world type, seed, structure toggle, and any startup commands.
- Optionally, add a custom icon by placing a PNG in the config directory and selecting it in the UI.
- Place datapacks in the
config/defaultworldgenerator/datapacksfolder; they will be loaded automatically. - Save the preset. If you want to force a single default, ensure only one preset is visible to players.
For older versions (1.9–1.11 or 1.8.9), configuration may require manual text file edits. Always check the documentation for your specific Minecraft version.
Server Deployment
On a dedicated server, Default World Generator (port): Lock World Type for Modpacks for Minecraft ensures the world starts with the correct preset every time. The mod can prompt an admin to choose a profile or automatically apply the designated one, bypassing the usual server.properties settings. This is invaluable for public servers where consistency is non-negotiable.
Compatibility and Licensing
The mod is built exclusively for Minecraft Forge and has been tested across numerous version branches. It coexists peacefully with other world-generation mods and datapack-heavy setups. Distributed under the MIT license, it can be freely included in any modpack without legal concerns.
