Butter

This library is my personal implementation of the SOAP architecture. It's free to use for personal and non-commercial projects. I'm a strong advisor for donationware, so please if you need to use it for commercial purposes donate anything here on itchio.

Most of my knowledge has been taken from these sources:

• Unite Austin 2017 - Game Architecture with Scriptable Objects
• Improve your Game Architecture with Scriptable Objects
• Game architecture with ScriptableObjects | Open Projects Devlog
• Create modular game architecture in Unity with ScriptableObjects

I'll keep updating the library as I learn more and implement new features.

Features

Before starting this section, keep in mind that Scriptable Objects live in the game's memory outside of a scene, and are generally publicly accessible by all memebers, which is why they are a good way to implement data decoupling and dependency inversion.

For use cases check out the wiki.

Scriptable Variables

A Scriptable Variable is a runtime variable that can represent a piece of data that you want to reference from different points. It can be player health, score, a simple flag to check whether you pressed New Game or Continue in the main menu... you can do pretty much anything with it, but it's supposed to be an atomic piece of data.

Scriptable Variables can also have persistent states, meaning that you can easily save and restore their state.

Scriptable Events

Scriptable Events are scriptable objects that make cross-component communication very easy and fexible.

Runtime Sets

Runtime sets are, just like the name suggests, sets that live in a Scriptable Object.

These can be useful to quickly define sets of items that you might want to reference somewhere else without having to create a hard link between scripts. In his talk at Unity, Ryan Hipple explains how at Schell Games they used this technique to quickly add some enemies to a set and reference them from another script that applied a custom renderer on top of them.

Installation

Navigate to the unity package manager, press the + icon to add a package and select "Install Package from git URL". Finally input https://github.com/xNicklaj/Butter.git as URL.

This should install the whole library. To check that it's working you can right click anywhere in your Assets folder and make sure that under Create you have Butter.

Alternatively you can install the latest package provided here on itchio, however I plan to only release LTS packages here.
