Custom Resource Types

You can add your own resource types by dropping JSON files into the config directory. No coding required.

Client & Server must match

This config registers actual blocks and items, so the client and server must use the exact same config. If they differ, the client will fail to connect (registry mismatch) and textures/models won't load correctly. Distribute the same config/resourcestrees files to every player and the server.

File Location

config/resourcestrees/resources_type/<name>.json

The filename (without .json) is used as the type's unique identifier. The name field inside the JSON must match.

The directory is created automatically on first launch.

JSON Format

{
  "name": "ruby",
  "material": "minecraft:redstone",
  "color": -3342336,
  "weight": 4,
  "saplingDropChance": 0.1,
  "leafDropChance": 0.2,
  "treeSimulatorTicks": 1400
}

Fields

Field	Description
name	Unique identifier. Must match the filename.
material	Item registry name used to craft the sapling. Prefix with # for an item tag.
color	ARGB integer tint color applied to leaves, sapling, and leaf fragment.
weight	No longer used (deprecated).
saplingDropChance	Chance (0.0–1.0) a sapling drops when leaves decay or are broken.
leafDropChance	Chance (0.0–1.0) a leaf fragment drops from a leaves block.
treeSimulatorTicks	Ticks per growth cycle in the Tree Simulator. Lower = faster.

Using an Item Tag as Material

Prefix the tag path with # to use an item tag:

{
  "name": "wood",
  "material": "#minecraft:logs",
  "color": -7508381
}

Color Conversion

The color field is an ARGB integer (signed 32-bit). To convert from a hex color:

#RRGGBB → 0xFF + RR + GG + BB as a signed int

For example, #CC0000 (dark red) = 0xFFCC0000 = -3342336 as a signed int.

You can calculate it in Java: (int) 0xFFCC0000

Or use an online signed 32-bit int converter.

Example: Ruby

config/resourcestrees/resources_type/ruby.json

{
  "name": "ruby",
  "material": "minecraft:redstone",
  "color": -3342336,
  "saplingDropChance": 0.1,
  "leafDropChance": 0.2,
  "treeSimulatorTicks": 1400
}

This creates:

• ruby_oak_sapling, ruby_birch_sapling, … (one per tree type)
• ruby_oak_leaves, ruby_birch_leaves, …
• ruby_leaf_fragment

All tinted with the specified red color.
