Library that extends vanilla worldgen by providing alternatives to unmodifiable features

## What is the goal of the mod?

The main goal of Reef is to take vanilla world gen and make it configurable. The way we want to achieve this is by not changing vanilla, but adding to it. So let's say we want to be able to customize the Ice Spike feature, the way Reef approaches this is by creating a new identical feature that is fully customizable. So there is no need for dirty mixins and breaking compatibility with other mods. This is not possible in all cases of course, and in those cases we will take the least intrusive option.

## What Does the mod do?

Reef does a lot of things! Well, only a few for now, but we have great plans. Currently, the mod adds duplicates of vanilla features that can be properly configured. Custom Tags have been added to enable icebergs or eroded badlands generation to occur in biomes. And a Custom StructurePool Projection (See warning section about this.)

## Contents

  • Custom Features:
  • - Spike ("Ice Spike" Feature, but customizable)
  • - Inverted Spike ("Spike" Feature, but is upside down)
  • - Monster Room ("Dungeon" Feature, but customizable)
  • - Structure Piece (Similar to "Fossil" Feature, but with no forced height offset)
  • - Large Cave Pillar ("Large Dripstone", but customizable)
  • - Feature List (Places all features in a list)
  • Custom Tags:
  • - `has_eroded_pillar` (Will apply a custom Eroded Badlands Surface Builder, which has been tweaked to use OCEAN_FLOOR_WG)
  • - `has_vanilla_badlands_pillar` (Will apply the vanilla Eroded Badlands Surface Builder. Should only be used to stop vanilla from generating. Will break in water)
  • - `has_iceberg` (Will apply the Iceberg Surface Builder)
  • StructurePool Projections:
  • - `SEAFLOOR_MATCHING` (Adds seafloor matching projection. See warning section about this.)

## Future of the lib

While this lib is only in the early stages of development. We already have plans to fully deprecate this mod. Since This is planned to be just one module from our future mod `VoidLib`.

Because it is nicer to have a single jar file for all the libs we use, kinda like Fapi or QSL

Then why not just release `VoidLib`? Because Gradle multi-module projects are hard :(

As the mod is currently in very early stages, so there are some kinks we have not fixed. As of the current version (0. 1. 2) here are the current warning:

#### StructurePool Projection `SEAFLOOR_MATCHING`

This projection exists but does not behave anything like expected. Please don't use it for anything, but testing.

#### Custom Features

All the current features were made quickly and very messily for a world gen mod we were working on. They have not been property cleaned up and optimized. So do expect them to change, both as features and their configs.

As of the current update (0. 1. 2) there is no wiki. This is just a note saying that Ender is working on one. If there isn't one more than a month after the (0. 1. 2) release, go @ Ender on discord
