Special Notice: As of release 13 (, Regrowth now keeps its configuration file in the common config folder (like many other mods) rather than the server config folder. 




With Regrowth, by default, right out of the box, animals and some monsters will eat plants, heal from eating, and promote plant regrowth.  Villagers will improve their villages with better lighting, stone walls and wood fences, fix impassable roads, fill potholes, cut grass and trim tree leaves and remove troublesome cactus.  All done very gently with essentially no impact on the server.  There's no need to configure anything.  You can download it and drop it into your Mods folder for client play.  You'll need a copy on the server and client for multiplayer server play.

Configuration Options

However, if you wish to customize Regrowth, you can control every aspect of Regrowth.  As a single player, server operator, or map designer you can turn features on or off- deciding which animals and creatures (including modded creatures) will consume plants, regrow plants or do both!   You can also change the timing so things happen more often-- or less often in easy to understand "seconds between events."  There are solid debugging tools to let you see what's happening while developing your configuration.

And, you can also control every aspect of how Villagers will improve their towns.  If you don't want them to cut the grass, you can turn that feature off.  If you want them to put torches in dark buildings, you can turn that feature on.  Over time, you can see as they build and light the village wall and fence in personal dwellings outside the village wall.


In Regrowth, there are "Non-Villager" or "Villager" actions. 

The Non Villager actions are words like "eat", "grow", "both", "tall", (and after 1.15) "stumble", "mushroom" (and after 1.16) "coral".   

Villager actions are a set of flags like "crwlptv".

Non-Villager Actions


When you configure a creature to eat plants, it will eat a single block of short grass, short ferns, short flowers or double high/tall grass or flowers which are on grass blocks. 

If you have configured healing to be on, creatures will heal a half heart of damage when they eat. 

If a creature is child, gets a small aging boost.  This should work for modded creatures too that use standard forge and minecraft base classes.

Horses, Donkeys, and Mules only eat while they are in their eating animation.

After an animal eats, sometimes the grass will turn to dirt.   If a pen is too crowded, eventually all the ground will be dirt.   


When you configure a creature to grow plants, it will causes a fertilization event on a bare grass block just as if a player used bonemeal.


When you configure a creature to do both,

the creature will "Eat" plants if on a grass block with plants.

otherwise the creature will "Grow" new plants on bare grass blocks lacking plants.

Coral (after 1.16)

Fish and squid will slowly regrow coral including fans, grass, and pickles.


When you configure a creature to grow Tall plants, it will grow short grass into tall grass.  By default, Creepers do this.

Stumble  (after 1.14)

When you configure a creature to stumble, it will occasionally kick over torches on the ground.  By, default Zombies do this.

If you want the effect to be more aggressive, lower the time from 60 seconds to 3or 6 seconds.

If you are upgrading, you'll need to manually add "stumble" lines to the configuration file.

Mushroom (after 1.14)

When you configure a creature to grow Mushrooms, if it is in an large underground space on stone (including any modded stone tagged as BASE_STONE_OVERWORLD), it will occasionally try to grow a giant mushroom.  By default, Skeletons do this.

If you want the effect to be more prolific, lower the time from 60 seconds to 3or 6 seconds.

If you are upgrading, you'll need to manually add "mushroom" lines to the configuration file.


When a creature (default: pigs) is in a biome with trees, it will occasionally plant saplings matching local trees.  In roofed forests, this is oak saplings.  It won't plant them close to other saplings or trees.

Villager Actions

Villagers have a set of flags instead a single command.   By default, all flags are on now.  This looks like "crwlptv" by default (tho the order doesn't matter).

You can configure villagers to do none, some or all of these actions.

"c" =cut grass near town (not flowers).

"h"= Level 2 clerics will heal wounded villagers (and players they don't hate) during gossip time based on their level.   Level 3+ smiths will hear wounded Iron Golems.

"r" = turn on road upgrades: Fix steep roads, fix 1 block deep holes in the road, fix unfinished parts of the road.

"w" =build a stone wall around the village meeting place, usually their bell. - with optional torches.  Don't block roads.   Villagers won't build overlapping walls in newer versions.  Villagers in a particular village won't build walls of the wall block over the village bell is removed.

"l"=Add torches inside buildings, caves, and under trees in areas that are too dark.  Add 1 torch to the desert farms next to composter in v15,16.

"p" =build a personal fence around homes outside of the village stone wall- with optional torches.  Don't block roads. (off by default)

"t" = put optional torches on the walls.  In future releases villagers may slowly add a few more torches over doors or inside houses lacking a torch.

"v" = Cut cactus and normal tree leaves that are too low and may block or damage villagers.  Will not cut persistent leaves such as those placed by players or parts of structures.

by default Level 3 farmers will not trample crops.

by default Villagers will trample down powdered snow into snow layers when they wander into it. 


Regrowth has the following commands for operator level and above.

/regrowth setDebugLevel [0,1,2]


Sets the debug level. 

0 does not log messages.

1 logs messages to the console and log file.

2 logs everything.   Use for short durations and analyze the log file afterwards.

/regrowth info

This shows information about Regrowth and *on the client* in single player mode will tell you the fully qualified name of the mob you are looking at.  I.e. "Minecraft:Creeper" or "AnotherMod:Creature" to help in configuration.  It does not work on a server.  It isn't fully implemented in 1.12.2.

There may be additional configuration commands in the future.


Walls and fences are built from biome suitable materials.  Desert towns have a smaller town wall.  Plains have a larger town wall.

The mobs do not *seek* grass.  They wander as normally and if a regrowthEvent occurs, then they check if they are in tallgrass or flowers or on a bare grassBlock.

You can currently edit the configurations manually.  There will be commands to support the configuration as in HappyTrails.

Note that you can put a default configuration files for all your mods (not just this one) in the folder "defaultconfigs" and new worlds will get them by default.

Experienced Farmers learn to avoid trampling farmland at level 3.

Q: Where is the configuration file?

A:  For 1.14.4, 1.15, and 1.16 (thru "saves/Worldname/serverconfigurations/regrowth-server.toml".   Starting with 1.16 ( it is in "config/regrowth-common.toml". 

Q: How do I save one configuration for all worlds?

A: Save a copy of your desired configuration in the "defaultconfigs" folder.

Q: Some players want walls other players do not.   

A: Players can remove the cobblestone wall over village meeting bells after the first 60 seconds and they won't be replaced.  Villagers will not build a wall if there isn't a wall block over the village meeting bell.


SPECIAL NOTE: Forge changed the way command line commands were handled as of 32.0.67.

 use Regrowth Version 1.16.1 v1.0.0.1 for Forge versions 32.0.24 to 32.0.66 

 use the current 1.16 version of Regrowth Version for later versions of Forge versions (32.0.67 onwards ) up thru version 32.0.22.  It may work after 32.0.22 but that's the last version it was tested on.
