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"
}

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.

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",
  "customBlockReplacements": [
    {
      "target": "farmersdelight:brown_mushroom_colony",
      "replacement": "minecraft:brown_mushroom",
      "damageTool": true
    },
    {
      "target": "farmersdelight:red_mushroom_colony",
      "replacement": "minecraft:red_mushroom",
      "damageTool": true
    }
  ],
  "useCustomBlockReplacements": true
}

Custom Block Replacements

The mod supports custom block replacement rules that allow you to automatically replace non-crop blocks with other blocks when broken. This is useful for blocks like mushroom colonies that should replant a mushroom when harvested.

Each custom block replacement rule has the following structure:

{
  "target": "farmersdelight:brown_mushroom_colony",
  "replacement": "minecraft:brown_mushroom", 
  "damageTool": true
}

Example Configuration:

"customBlockReplacements": [
  {
    "target": "farmersdelight:brown_mushroom_colony",
    "replacement": "minecraft:brown_mushroom",
    "damageTool": true
  },
  {
    "target": "farmersdelight:red_mushroom_colony", 
    "replacement": "minecraft:red_mushroom",
    "damageTool": false
  }
]

How It Works:

• When you break a farmersdelight:brown_mushroom_colony with a valid tool, it will automatically place a minecraft:brown_mushroom in its place
• The original block's drops are spawned, minus one of the replacement item (to simulate using it for replanting)
• Tool damage is applied based on the damageTool setting for each rule
• All other configuration options (tool requirements, sneak mode, etc.) still apply

Notes:

• Custom block replacements work independently of crop blocks
• The useCustomBlockReplacements setting must be true for this feature to work
• Block IDs must be valid and exist in your game (including mod blocks)
• If the replacement block ID is invalid, that rule will be ignored

Auto Replanter Enchantment Support

There is an additional, optional datapack to add enchantment support. If a tool has the Auto Replanter Enchantment (regardless of its type or whether it matches your configured tags or item lists), it will always be considered a valid tool for auto-replanting. This means you can enchant any tool with the Auto Replanter enchantment and it will work with the mod, even if it is not listed in validToolTags or validTools. The tools that can be enchanted are defined in the Auto Replanter Enchantment data pack.

If this datapack is enabled, the mod will automatically detect it with no config required. To enforce the enchantmentand ignore any valid tools as defined using the config settings described above, simply set useValidToolTags and useValidTools to false in the config.

The Auto Replanter Enchantment datapack is available on Modrinth

Note:

The other configuration settings—such as requireTool, sneakMode, and tool durability—still apply.

• If requireTool is set to false, any tool (or even no tool) will work, regardless of enchantment.

• If requireTool is true, a tool with the Auto Replanter enchantment will always be valid, even if it doesn't match your tags or item lists.

• The sneak mode and tool damage settings are still respected.

This allows for more flexibility: you can give the enchantment to custom tools, modded tools, or even vanilla tools not normally allowed by your config, and they will work seamlessly with auto-replanting.

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.

Custom Block Harvesting

Use custom block replacements to automatically replant modded blocks like mushroom colonies:

"customBlockReplacements": [
  {
    "target": "farmersdelight:brown_mushroom_colony",
    "replacement": "minecraft:brown_mushroom",
    "damageTool": true
  }
]

Using the default values, when you break a brown mushroom colony from Farmer's Delight (having met the valid criteria to trigger automatic replanting), it will automatically place a brown mushroom and drop the colony's normal loot (minus one brown mushroom used for replanting).

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.

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?

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.

Q: Can I use custom block replacements with any modded blocks?

A: Yes, as long as you specify valid block IDs for both the target and replacement blocks. The blocks must exist in your game for the replacement to work.

Q: Do custom block replacements work with crops?

A: Custom block replacements are designed for non-crop blocks. Regular crops are handled by the mod's built-in crop replanting system. If a crop block is also defined in the custom block replacement config, crop breaking logic will take precedence.

Q: Can I disable tool damage for specific custom blocks?

A: Yes! Set "damageTool": false in the custom block replacement rule to prevent tool damage for that specific block. Note that crop blocks take precedence over custom blocks, so if a crop block is defined in the custom blocks, its damageTool value will be ignored in favour of the crop block logic.
