Water erodes the landscape creating streams and waterfalls producing gravel, sand, clay, and moss

Water escapes from lakes and aquifers. Dirt and sand wash away to deepen stream beds and cut river banks. Find Forest brooks and Mountain creeks in your explorations. Pass through a dry Desert valley one day and find it flooded the next. Supports Forge for 1.12+ and Fabric for 1.14+.

Erosion in Minecraft, just like real life, is a slow process. You must wait see to the effects or increase the random tick speed.

Goals

  • Implement Water Erosion as though it were a default Minecraft feature to make worlds more dynamic.
  • Provide a renewable source of Coarse Dirt, Sand, and Clay fitting into the stock game mechanics.
  • Avoid breaking stock existing game play.

Features/Rules

  • Water flowing over an edge erodes the block below.
  • Water flowing into a block "saturates", then dissolves the "wall." Turns towards the closest air space.
  • Water flow ends "saturate", then dissolve the block below to potentially continue the flow downhill.
  • Water Sources dissolve blocks to the side in the direction of air spaces.
  • Erodable blocks include sand, gravel, clay, farmland, dirt, grass, and, rarely, cobblestone.
  • Erodable blocks have differing resistances to erosion depending on their density, but all erode over time.
  • Blocks decay during erosion to weaker blocks before disappearing.
  • Blocks decay upstream in stream beds.
  • Cobblestone and Stone Bricks grow moss near water.
  • Enable/disable Farmland erosion via config file (Forge for 1.14+ only for now)

Decay hierarchy:

  • Cobblestone -> Mossy Cobblestone -> Gravel
  • Stone Bricks -> Mossy Stone Bricks -> Gravel
  • Grass Path -> Grass -> Dirt -> Coarse Dirt -> Gravel
  • Gravel -> Sand -> Clay(rarely) -> Air/Water.

Have an idea about how it could be even better? Let me know in the comments or issues!

Installation

Fabric versions

Download the current release water-erosion-x.x.x-fabric-x.x.x.jar and add to your installation.

Forge versions

The Forge version for Minecraft 1.12.2 is a Coremod containing an embedded copy of the org.spongepowered.asm.launch.MixinTweaker library. It does NOT require MixinBootstrap.

The Forge versions for Minecraft 1.14.4+ require MixinBootstrap. Download the current release water-erosion-x.x.x-forge-x.x.x.jar, then download the MixinBootstrap-1.0.0.jar. Put both files in your MinecraftForge Mod folder.

Technical Notes

This "core mod" adds code to the Water block randomTick() functions using the Mixin frameworkrandomTick() is only called by the Minecraft runtime for a 128 block radius around the player, so the odds of erosion occurring are set fairly high.

Tutorial

Sand can be generated from gravel with a simple machine

Test Areas

Create each world, teleport to the specified location, and, optionally, change the randomTickSpeed setting to speed up the process. Note: You must wait upwards of 30 real minutes to see the effects if you do not change the randomTickSpeed, such as in a survival world.
