What is Modula?

Modula is a package for Unity Engine that helps splitting your code into smaller independent parts. Get Started

When needed, inherit from ModularBehaviour instead of Unity’s default MonoBehaviour class. This lets you split all the logic inside of your component and move it into independent modules, which could later be connected to/removed from each instance of that component, using the inspector GUI:

That way by distributing the code into small self-containing modules you could make the codebase cleaner and easier to understand.

Brief Overview

The final gameobject designed using Modula should consist of these components:

Main behaviour script

// Main Behaviour
    public class Car : ModularBehaviour
    {
         // Your code as you do it usually
         ...
    }

Some connected modules

// Example Module
    public class Engine : Module 
     {
         void Start() { ... }
         
         ...
     }

`Pros & Cons`

Faster updates: don’t need to wait for Unity team to approve the package. Download updates right when they’re ready and published
“Under the Hood” usage: no code in your Assets/ folder at all.

con: it’s not so straightforward to dig into the source code because it’s hidden in Packages/ folder.

Choose this method if you want Modula to work under the hood without littering your Assets/ folder.

There are other installation methods listed at “Installation” page.
