Introduction and Instillation

Instillation

Install the mod and its two dependencies Architectury and Rhino.
Make you use the most resent version of each mods for your version.
If you are using 1.16 fabric then use this instead.

When you first install KubeJS, you will need to launch Minecraft with the mods (and the game not crashing) to generate the some folders and files.

The `kubejs` folder

Finding it

Everything you do in KubeJS in located in the kubejs folder in your instance.

In PolyMC the file structure will look like polymc > instances > instance name > minecraft > kubejs
In CurseForge launcher the file structure will look like curseforge > minecraft > instances > instance name > kubejs
In both of these cases the instance name is the name of the instance

From now on this will be referenced as the kubejs folder.

The contents of it

startup_scripts
- Scripts that get loaded once during game startup
- Used for adding items and other things that can only happen while the game is loading
- Can reload code not in an event with /kubejs reload_startup_scripts
- To reload all the code you must restart the game
client_scripts
- Scripts that get loaded every time client resources reload
- Used for:
  - JEI events
  - tooltips
  - other client side things
- Can reload code not in an event with /kubejs reload client_scripts
- Can reload all the code in client_scripts with F3+T
server_scripts
- Scripts that get loaded every time server resources reload (world load, /reload)
- Used for modifying:
  - recipes
  - tags
  - loot tables
  - handling server events
- Can reload code not in an event with /kubejs reload server_scripts
- Can be all the code in server_scripts with /reload
exported
- Data dumps like texture atlases end up here
config
- KubeJS config storage.
- This is also the only directory that scripts can access other than world directory
assets
- Acts as a resource pack
- you can put any client resources in here, like:
  - textures
    - Example: assets/kubejs/textures/item/test_item.png
  - models
  - lang
  - etc.
- Can be reloaded by pressing F3 + T
- Can reload only the lang files (so faster) /kubejs reload lang
- Read more about it here.
data
- Acts as a datapack
- you can put any server resources in here, like:
  - loot tables
    - Example: data/kubejs/loot_tables/blocks/test_block.json
  - functions
  - etc
- Can be reloaded with /reload
- Read more about it here.
README.txt
- Contains the information here

You can find type-specific logs in logs/kubejs/ directory

Other Useful Tools

Code is just a language that computers can understand. However, the grammar of the language, called syntax for code, is very precise. When you code has a syntactical error, the computer does not know what to do and will probably do something that you do not desire.

With KubeJS we will be writing a lot of code, so it important to avoid these errors. Luckily, there are tools called code editors, that can help us write code correctly.
