OldGenerator

Spigot/Paper/Folia plugin for adding Beta 1.7.3 generation to modern versions of
Minecraft. This plugin can replace
173generator for modern versions (please
see the How to Use section for proper configuration).

Differences

Overworld

Block physics are not applied to gravel OR sand when placing. So, the dungeon sand will
not immediately cave in upon logging in, but the dungeon is still there .
Most chunks will look the exact same, but due to chunk generation order differences
the populators might fire differently and you'll get different results (however the general
terrain will remain the same).

Nether

Fire, glowstone, and even lava placement (excluding the lava oceans) will generally not mirror Beta 1.7.3. However, the terrain
will remain the same.

Why aren't fire/glowstone/lava correct? This is due to a technical bug in the old
beta populator code: The chunk seed is not setup when populating chunks! So the
placement is entirely dependent on chunk generation order (and a few other really technical details),
which is completely different in modern Minecraft.

There's nothing I can do to match the old populator behavior, however I have modified the
populator code for nether to correctly setup a chunk seed per chunk - this means the results
should be consistent across world generations when using OldGenerator, but they still will not
match Vanilla Beta 1.7.3.

How do I use?

If you do NOT have a world management plugin

Add this to your bukkit.yml

worlds:
  worldname1:
    generator: OldGenerator:b173
  worldname2:
    generator: OldGenerator:b173

This will setup worldname1 and worldname2 to run OldGenerator as their generator. For example,
you can set worldname1 to world and worldname2 to world_nether to do exactly what you expect.
b173 can be replaced with sb173 to get a skylands world.

If you have a world management plugin

Follow the guide that world management plugin to setup custom generators. I don't
use any world management plugins, so I can't help you!

I want different old generators!

If enough people request other old generators, I can add them to this plugin.
