⚛️ Unity Atoms

Tiny modular pieces utilizing the power of Scriptable Objects

Influences

Unity Atoms is derived from and a continuation of Ryan Hipple's talk from Unite 2017. The original source code can be found here.

This talk by Richard Fine is a forerunner to Ryan Hipple's talk during Unite 2016.

Motivation

The general approach to building scripts in Unity often generates a code base that is monolithic. This results in that your code is cumbersome to test, non-modular and hard to debug and understand.

Unity Atoms is an open source library that aims to make your game code:

• 📦 Modular - avoid scripts and systems directly dependent on each other
• ✏️ Editable - Scriptable Objects makes it possible to make changes to your game at runtime
• 🐛 Debuggable - modular code is easier to debug than tightly coupled code

Installation

NPM

Prerequisite: Since Unity Atoms is using the Unity Package Manager (UPM) you need to use Unity version 2018.3 >=

Add the following to your manifest.json (which is located under your project location in the folder Packages):

{
    "scopedRegistries": [
        {
            "name": "NPM Registry",
            "url": "https://registry.npmjs.org",
            "scopes": [
                "com.unity-atoms.unity-atoms-core",
                "com.unity-atoms.unity-atoms-base-atoms",
                "com.unity-atoms.unity-atoms-fsm",
                "com.unity-atoms.unity-atoms-mobile",
                "com.unity-atoms.unity-atoms-mono-hooks",
                "com.unity-atoms.unity-atoms-tags",
                "com.unity-atoms.unity-atoms-scene-mgmt",
                "com.unity-atoms.unity-atoms-ui",
		        "com.unity-atoms.unity-atoms-input-system"
            ]
        }
    ],
    "dependencies": {
        ...
        "com.unity-atoms.unity-atoms-core": "4.4.5",
        "com.unity-atoms.unity-atoms-base-atoms": "4.4.5",
        "com.unity-atoms.unity-atoms-fsm": "4.4.5",
        "com.unity-atoms.unity-atoms-mobile": "4.4.5",
        "com.unity-atoms.unity-atoms-mono-hooks": "4.4.5",
        "com.unity-atoms.unity-atoms-tags": "4.4.5",
        "com.unity-atoms.unity-atoms-scene-mgmt": "4.4.5",
        "com.unity-atoms.unity-atoms-ui": "4.4.5",
	    "com.unity-atoms.unity-atoms-input-system": "4.4.5",
        ...
    }
}

Note that the core and base atoms packages are mandatory while the others are optional. If you don't want a subpackage, simply remove it from your dependencies. Note that subpackages may have additional dependencies.

OpenUPM

The package is available on the openupm registry. It's recommended to install it via openupm-cli.

# required
openupm add com.unity-atoms.unity-atoms-core
openupm add com.unity-atoms.unity-atoms-base-atoms

# optional
openupm add com.unity-atoms.unity-atoms-fsm
openupm add com.unity-atoms.unity-atoms-mobile
openupm add com.unity-atoms.unity-atoms-mono-hooks
openupm add com.unity-atoms.unity-atoms-tags
openupm add com.unity-atoms.unity-atoms-scene-mgmt
openupm add com.unity-atoms.unity-atoms-ui
openupm add com.unity-atoms.unity-atoms-input-system
