It contains several example scripts as well as Intellisense(autocompletion) for CustomNPCs.

NOTE: This repo is still WIP. Snippets and Typings are still in the making. Intellisense for 1.12.2 is done! Check it out in the 1.12.2 branch! (1.16.5 coming soon)

Requirements for scripting

1. Install Visual Studio Code

Visual Studio Code is one of many editors to use in scripting/programming. We use it for its ability to make scripting really easy.

Make sure to download VSCode from its official website.

2. Choose a scripting language

CustomNPCs allows you to choose your own language to script in. You only have to download a specific .jar file for your chosen language. Click here for info about enabling scripting

This repo contains only javascript examples for now so we assume you downloaded nashorn.jar.

If you are running CustomNPCs on a server, then only the server needs nashorn.jar.

If you are making a modpack for singleplayer or self-host use you'll need to include nashorn.jar in your modpack. This can be problematic if you have a CurseForge modpack, but is easily solved because someone uploaded nashorn.jar to CurseForge

3. Download this repo

Download this repository and open it up in VSCode to get started! Create some directories. Organize the example files how you want it.

Do NOT remove jsconfig.json and .vscode or you'll lose your autocompletion feature.

Getting started

Your first script

Decide what type of script you want to make. You can choose from:

• NPC Script (Scripts that are executed by NPCs)
• Item Script (Scripts that are executed by scripted items)
• Block Script (Scripts that are executed by scripted blocks)
• Player Script (Scripts that are executed by every player)

TODO: add explanation on in-game steps to run scripts

The good stuff

This repo contains some extra handy files to enhance your scripting experience.

Snippets

Intellisense (autocomplete)

FAQ

Intellisense/autocomplete is not working anymore

Make sure your jsconfig.json and .vscode still exists within the root of your opened VSCode project.

What is all the @param stuff?

This is required for VSCode to know what we are programming. It tells VSCode stuff about the code.
