dtcraft-datapacks

A collection of vanilla enhancement datapacks and utilities. Click on the following datapacks for specific usage and installation information or see the general Installation section here.

Note These datapacks are in development and may not be stable or up to date.

Autocraft

Automate the crafting process with a redstone enabled crafting table.

Inventory Sort

A quality of life datapack that will sort your inventory (excluding hotbar) into a defined group ordering.

Refill

Automatically refill an empty stack of a hotbar item with available stacks from your inventory.

Library Datapacks

The following datapacks are libraries of functions that are intended to be used by other datapacks, and are not standalone.

Call-stack

This datapack provides some bare bones support for a call stack like data structure, providing scope to your function variables. This is very convenient for avoiding side effects from other functions overwriting variable values.

Array

This datapack encapsulates common array operations.

Crafting

This datapack offers an api for crafting items from recipes through commands.

Inventory

This datapack offers a number of commonly repeated functions for manipulating player inventories complete with shulker box looting. Functions include, getting only hotbar items, only inventory items, replacing a single slot of user inventory with custom item, getting first item by id, and getting all items by id. Other functionality will be added as needed.

Raycast

A utility datapack used for performing raycasts with configurable parameters.

Custom-Block

Easily create blocks with custom models and behaviors.

GUI

Easily create container based GUIs.

Unit-Test

This datapack offers an api for testing functions. Additionally includes experimental multi-tick testing functionality.

Installation

Navigate to the Releases tab and download the desired datapack's .zip file. Copy the zip file into your Minecraft world's datapacks folder. Open your Minecraft world and type /reload.

Library datapacks (intended for datapack devs) such as call-stack or crafting can be added to existing datapacks with Lantern Load. This entails adding the load function of the library datapack to the load.json tag. For example:

{
    "values": [
        "dt.crafting:load",
        "your_pack:load"
    ]
}

Building From Source

1. Create a datapack development directory and change directories into it. For example,

   mkdir -p dev/datapacks; cd dev/datapacks

2. Clone this repository into your datapack development directory

   git clone git@github.com:dthigpen/dtcraft-datapacks.git

3. Create a libraries directory, and put the latest compatible PlayerDB release zip into it.

4. You should have something like

   ls
   dtcraft-datapacks/
   libraries/
       playerdb-v1.20.zip

5. Navigate into the dtcraft-datapacks directory with cd dtcraft-datapacks.

6. Create and source a Python virtual envirnment so that we can install project dependencies. Remember to run the source command in the future.

   python -m venv env
   source env/bin/activate

7. Install dependencies with pip.

   pip install -e .

8. Run build tasks with invoke.

   # show commands
   invoke --list
   # bundle the datapack with dependencies
   invoke bundle autocraft ~/.minecraft/saves/test-world/datapacks --watch

Datapack Conventions

All of these datapacks utilize the call-stack utility when calling functions. Functions that implement this utility have function level variables, arguments, and return values without chance of side effects from other functions.

Example

example.mcfunction

data modify storage call_stack: call.arg0 set value "foo"
function namespace:some/function
data modify storage namespace:storage from storage call_stack: call.return

lib/foo_bar.mcfunction

# push a new frame to the stack
function call_stack:push

data modify storage call_stack: this.foo set from storage call_stack: this.arg0
data modify storage call_stack: this.return value "bar"

# pop the frame and replace with parent frame
function call_stack:pop

See the call-stack for more details.

To Do

• Update libraries and dependencies to current Minecraft version
• Update pre-macro mcfunction methods
• Update recursive functions to use return
• Update tree functions to use return
