Useless Numerical
No more conflict with integer IDs in BTA
With this mod, you no longer need to worry about configuring other mods to avoid block and item ID conflicts.
It also lets you detect when a world is missing a block or item (as long as the world has already been loaded once with this mod).
Best of all, it is fully compatible with both client and server, which makes sharing worlds easy.
How does it work?
The mod saves, inside each world, a mapping between BTA’s future NamespaceID and its numeric ID.
If a conflict occurs, it automatically assigns a new numeric ID to the NamespaceID.
When you open a save or join a server, the mod checks if any blocks or items are missing and then verifies whether the ID mapping is correct.
If the mapping is incorrect, you’ll be prompted with a button to restart Minecraft.
This ensures that your current game and world stays compatible without any weird issue.
The big advantage is that it makes sharing your Minecraft world with others, or connecting to a server, simple and hassle-free.
