Auto Replanter

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

Demo

Features

• Automatic Crop Replanting: Crops are instantly replanted at age 0 when broken
• Dual Tool Validation System: Choose between tag-based and specific item-based tool requirements
• Configurable Tool Requirements: Choose whether specific tools are required for auto-replanting
• Smart Tool Damage: Tools take durability damage with full enchantment support (such as Unbreaking)
• Mature vs Immature Handling: Different behaviour for fully grown vs growing crops
• Sneak Mode Control: Configure auto-replanting to work always, only while sneaking, or only while standing
• Highly Configurable: Extensive configuration options to customise behaviour
• Mod Compatibility: Works with any modded crops that extend Minecraft's CropBlock

Installation

1. Install Fabric Loader
2. Download the mod jar from CurseForge
3. Place the jar file in your mods folder
4. 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
• Respects enchantments like Unbreaking
• 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.
