The Sims 4 Community Library

The Sims 4 Community Library

An open source library with a focus on providing utilities and services to the larger Sims 4 modding community. Let’s not reinvent the wheel!

This is more of an API than a mod itself. It does nothing on its own and is meant as a framework for other Sims 4 developers to utilize in their own code
bases. Only install the library if you have installed a mod that requires it!

Planned Features:
– For a list of planned features, take a look at the repository.

Note for Modders:
– If you have ideas for additions to add or want one of the planned features sooner rather than later, I’m all ears! Let’s work together to create a library that we all can use!
– To see the documentation for S4CL check out the docs!

What is the workflow for working with S4CL?
– Create a project based off of the Template Project
– Use the green button in the top right The Main Page to download this project as a zip file.
– In your project, create another directory called `S4CL`.
– Open the downloaded project and copy the `Scripts/sims4communitylib` folder into the `S4CL` folder we created in the previous step. The folder structure should then be: `/S4CL/sims4communitylib`
– Right click the `S4CL` folder -> Mark Directory as -> Sources Root
– The `S4CL` folder should turn a blue color and the `sims4communitylib` folder should look like a folder with a dot (In other words, it should NOT be blue).
– Your folder structure should look like this: `/S4CL/sims4communitylib` at this point.
– Ensure you list in the description of your mod a link to the github releases (You may even link a specific release to ensure compatibility.)
– Ensure you properly attribute S4CL and its author according to the license located at the bottom of this readme.
– In order to prevent users from accidentally installing multiple copies of S4CL into their Mods folder, it is preferred to redirect the users of your mod to download S4CL from either the github repository or releases pages instead of bundling it with your mod.
