Auto Replanter

A Minecraft Fabric mod that automatically replants crops when harvested, eliminating the tedious task of manually replanting seeds after breaking crops.

Demo

Auto Replanter Showcase - Breaking crops with a hoe automatically replants them

Features

Automatic Crop Replanting: Crops are instantly replanted at age 0 when broken

Mod Compatibility: Works with any modded crops that extend Minecraft's CropBlock

Installation

Install Fabric Loader
Download the mod jar from CurseForge
Place the jar file in your mods folder
Launch the game

Configuration

The mod creates a configuration file at config/autoreplanter.json on first run. You can edit this file to customise the mod's behaviour.

Configuration Options

{
  "validToolTags": ["minecraft:hoes", "farmersdelight:tools/knives"],
  "validTools": ["minecraft:diamond_hoe", "farmersdelight:flint_knife"],
  "enableAutoReplanting": true,
  "damageTools": true,
  "requireTool": true,
  "useValidToolTags": true,
  "useValidTools": false,
  "onlyDamageOnMatureCrop": true,
  "sneakMode": "ALWAYS"
}

Option	Type	Default	Description
`validToolTags`	Array	`["minecraft:hoes", "farmersdelight:tools/knives"]`	List of item tags that are considered valid tools for auto-replanting. Only takes effect when `useValidToolTags` is `true`
`validTools`	Array	`["minecraft:diamond_hoe", "farmersdelight:flint_knife"]`	List of specific item IDs that are considered valid tools for auto-replanting. Only takes effect when `useValidTools` is `true`
`enableAutoReplanting`	Boolean	`true`	Master switch to enable/disable the mod
`damageTools`	Boolean	`true`	Whether tools should take durability damage when used
`requireTool`	Boolean	`true`	Whether a valid tool is required for auto-replanting to occur
`useValidToolTags`	Boolean	`true`	Whether to use tag-based tool validation. When `false`, the `validToolTags` list is ignored
`useValidTools`	Boolean	`false`	Whether to use specific item-based tool validation. When `false`, the `validTools` list is ignored
`onlyDamageOnMatureCrop`	Boolean	`true`	Whether tools should only take damage when harvesting mature crops
`sneakMode`	String	`"ALWAYS"`	Controls when auto-replanting occurs based on sneak state. Options: `"ALWAYS"`, `"ONLY_SNEAKING"`, `"ONLY_STANDING"`

Sneak Mode Options

The sneakMode setting controls when auto-replanting should occur based on whether the player is sneaking:

"ALWAYS" (default): Auto-replanting works regardless of sneak state
"ONLY_SNEAKING": Auto-replanting only works while the player is sneaking
"ONLY_STANDING": Auto-replanting only works while the player is NOT sneaking

Tool Validation Systems

The mod offers two complementary tool validation systems that can be used independently or together:

Tag-Based Validation (`validToolTags`)

The validToolTags option accepts item tags in the following formats:

Simple tags: "minecraft:hoes"
Category tags: "farmersdelight:tools/knives"

You can add tags from any mod to customise which tools trigger auto-replanting. This list only takes effect when useValidToolTags is set to true.

Specific Item Validation (`validTools`)

The validTools option accepts specific item IDs in the format:

"namespace:item_id" (e.g., "minecraft:diamond_hoe", "farmersdelight:flint_knife")

This allows you to specify exact tools that should work with auto-replanting. This list only takes effect when useValidTools is set to true.

Combining Both Systems

You can use both validation systems simultaneously by setting both useValidToolTags and useValidTools to true. In this case, a tool is considered valid if it matches either the tag-based criteria or the specific item criteria.

Usage Examples

Default Behaviour

Use a hoe (from the minecraft:hoes tag) or knife (from the farmersdelight:tools/knives tag)
Works regardless of whether you're sneaking
Mature crops drop their items (minus one seed)
Crop is automatically replanted
Tool takes 1 durability damage

Sneak-Only Mode

Set "sneakMode": "ONLY_SNEAKING" to only auto-replant while sneaking. This gives you precise control over when crops are replanted, preventing accidental replanting when walking through your farm.

No-Sneak Mode

Set "sneakMode": "ONLY_STANDING" to only auto-replant while not sneaking. This allows you to disable auto-replanting by holding sneak, useful when you want to manually break crops without replanting (e.g., when relocating your farm).

Tag-Based Tools Only

Set "useValidTools": false to only use tag-based validation. The validTools list will be ignored.

Specific Tools Only

Set "useValidToolTags": false to only use specific item validation. The validToolTags list will be ignored.

No Tool Required

Set "requireTool": false to enable auto-replanting regardless of what tool is used (or no tool at all). When this is disabled, both validation systems are bypassed.

Preserve Tool Durability

Set "damageTools": false to prevent tools from taking any durability damage.

Only Damage on Harvest

Set "onlyDamageOnMatureCrop": true (default) to only damage tools when actually harvesting mature crops, not when replanting immature ones. This saves needless tool durability loss when accidentally breaking crops that are not fully grown when they are automatically replanted.

Supported Crops

The mod works with:

All vanilla Minecraft crops (wheat, carrots, potatoes, beetroot, etc.)
Any modded crops that extend Minecraft's CropBlock class
This includes crops from popular mods like Farmer's Delight (tested and working), and should work for other mods such as Croptopia, and many others, though these have not been tested.

Compatibility

Minecraft Version: 1.21.1
Mod Loader: Fabric
Dependencies: Fabric API
Compatible with: Most farming and agriculture mods, specifically those that extend Minecraft's CropBlock class.

Technical Details

Uses Fabric's PlayerBlockBreakEvents.BEFORE to intercept crop breaking

Server-side only logic (works on both single-player and multiplayer)
Automatic config generation and validation
Dual tool validation system supports both tag-based and item-specific matching

FAQ

Q: Does this work on servers?

A: Yes! The mod works on both single-player and multiplayer servers.

Q: Can I change the config without restarting?

A: No, you need to restart Minecraft (or the server) for config changes to take effect.

Q: Does this work with modded crops?

A: Yes, as long as the modded crops extend Minecraft's CropBlock class, then this should work.

Q: Will tools with Unbreaking last longer?

A: Yes! The mod uses Minecraft's built-in durability system, so all enchantments work normally.

Q: I added items to `validTools` but they don't work. Why?

A: Make sure useValidTools is set to true in your config. If it's false, the validTools list is ignored.

Q: Can I use both tag-based and specific item validation?

A: Yes! Set both useValidToolTags and useValidTools to true. A tool will be considered valid if it matches either system.

Q: How do I disable one of the validation systems?

A: Set either useValidToolTags or useValidTools to false to disable that respective validation system. The corresponding list (validToolTags or validTools) will then be ignored.

Q: What's the difference between the sneak modes?

A: "ALWAYS" works regardless of sneaking, "ONLY_SNEAKING" only works while sneaking (for precise control), and "ONLY_STANDING" only works while not sneaking (so you can disable it by sneaking).

Q: Can I set an invalid sneak mode?

A: If you set an invalid sneak mode in the config, the mod will fall back to "ALWAYS" behavior.
