shapez.io Modding

General Instructions

Currently there are two options to develop mods for shapez.io:

1. Writing single file mods, which doesn't require any additional tools and can be loaded directly in the game
2. Using the create-shapezio-mod package. This package is still in development but allows you to pack multiple files and images into a single mod file, so you don't have to base64 encode your images etc.

Mod Developer Discord

A great place to get help with mod development is the official shapez.io modloader discord.

Setting up your development environment

The simplest way of developing mods is by just creating a mymod.js file and putting it in the mods/ folder of the standalone (You can find the mods/ folder by clicking "Open Mods Folder" in the shapez.io Standalone, be sure to select the 1.5.0-modloader branch on Steam).

You can then add --dev to the launch options on Steam. This adds an application menu where you can click "Restart" to reload your mod, and will also show the developer console where you can see any potential errors.
