Anti Entity Grief
A minecraft mod for fabric, allowing you to control the griefing capabilities of entities!
Summary
Entities can grief the world in all sorts of ways, leading from minor nuisances to major issues. The team at Mojang recognised this and so added the gamerule mobGriefing which allows you to disable all mobs from griefing. Unfortunately this is too broad a command to be useful, since in your attempt to disable endermen from stealing blocks you have now stopped your villagers from farming crops!
VanillaTweaks has some fantastic datapacks to handle this, namely 'Anti Creeper Grief', 'Anti Enerman Grief', and 'Anti Ghast Grief'. However these require downloading multiple datapacks to the server, and have limited control over entities due to the capabilities of datapacks.
This mod introduces a new method of applying settings per-entity type. It includes settings unique to each type (e.g. separate pick up / place block options for endermen) as well as generic settings (e.g. trampling crops).
Usage
This section contains examples of how to use the commands provided by this mod to control the behaviours of entities.
The commands take on the following form:
/entityGriefing <entity> [<capability> [true|false]]
/entityGriefingAll <capability> <true|false>
/entityGriefingReset
where <entity> is the entity type you want to control, <capability> is the type of griefing you want to control, and [true|false] is whether you want to enable or disable the capability.
Not all entities will appear in tab-completion, either because I haven't identified any griefing capabilities or because they haven't been implemented yet. Please open an issue on GitHub or visit my Discord to let me know if there is a missing feature that you feel should be included.
For example, to stop endermen from picking up blocks, you would run:
/entityGriefing minecraft:enderman DESTROY_BLOCKS false
To set the BREAK_DOORS permission for all applicable entities, you would run:
/entityGriefingAll BREAK_DOORS false
To see if villagers can farm crops, you would run:
/entityGriefing minecraft:villager FARM_CROPS
And finally to see all the things that a pig can do, you would run:
/entityGriefing minecraft:pig ALL

All Versions
+ Add Version- Technical Updates**
- Mixins now use WrapOperation instead of Redirect for better compatibility
- Mixins now have
idfor Injects for better compatibility - A couple of tweaks to align with 1.21.5 code changes
- Changes**
- Move config loading to occur after capability inference
- Explanation**
In this mod, entities have two types of capabilities: **pre-set** and **inferred**. Pre-set capabilities are explicitly defined in configuration files (e.g., a Blaze being able to set things on fire). Inferred capabilities, on the other hand, are determined dynamically at runtime based on Minecraft’s internal calculations (e.g., a mob’s size determining whether it can trample crops).
Previously, the mod loaded configuration files immediately on startup, before inferred capabilities were assigned to entity types. This caused issues when attempting to apply inferred configurations—since they technically didn’t exist yet, the system would reject them.
To fix this, configuration loading is now delayed until after the world has fully loaded. By that point, all inferred capabilities are already assigned, ensuring that the stored configurations can be correctly applied without rejection.
Edit 2024-12-10: Fixed a bug from the previous upload that failed to properly save and load the configs.

A new backport for 1.20.1, based off the latest release. Includes all the latest features, minus the support for any entities added _after_ this update.
Apologies for the delay on this one. Life has kept me busy, and it also ended up being a fairly large update to handle.
- Changes**
- Added colours to commands for easier reading
- Updated the
/entityGriefingcommand so you can print all options for a single entity by typing/entityGriefing <entity>. Previously you had to select the 'ALL' option. - Added support for the creaking mob.
The original
TRAMPLE_CROPS capability has now been split into TRAMPLE_CROPS and TRAMPLE_FARMLAND by request.For more details, check the newly updated mod description.
Additionally, previous versions were incorrectly overwriting calculated configurations (e.g.
BREAK_DOORS) whenever the server was restarted, setting them back to their defaults. This issue has now been resolved.This version fixes a bug with egg trampling. In the previous versions, zombie variants always had egg trampling disabled (even if the rule was set to TRUE). This has now been amended.
Additionally, the trampling setting has been modified so that zombies+ will still target eggs even if they cannot destroy them. This is to maintain their vanilla behaviour whilst still adhering to the mob griefing rule.
Added
ALL to the list of capabilities available in commands, to make some things easier.Unfortunately due to internal MC limitations, the same could not be done for entities and so the
entityGriefingAll command still exists for that purpose.- Visible changes**
- Added assets and icons
- Technical changes**
- Updated a mixins to the latest version (FoxEatBerriesGoal, PrimedTNT), among other small update changes
Anti Entity Grief has now been made public and released! Change log is.. the whole mod!
This is for Minecraft 1.20.6, and I'll be working on a 1.21 release alongside the snapshots as they come out.
Hope you all enjoy :) Feel free to suggest new features!
