About This File


The Sims 4 Community Library


An API, for The Sims 4, used to make creating/writing mods using Python much easier and more accessible. On its own it does only a few debug commands/interactions. Only install this API if you also have a mod installed that requires it! This mod is intended to always be backwards compatible, so it is recommended to always keep it up to date!

  1. Download the API using the links at the bottom of this description
  2. Unpack the archive using your favorite archiving tool.
  3. Drag the files and folders to your The Sims 4 directory. The files will be at `The Sims 4/Mods`. Overwrite All if asked!
  4. Keep in mind the ts4script file MUST be either top level (Directly in the Mods/folder) or one folder deep (Mods/Blah/). Any deeper and it will not work.
    The final paths for the files should be the following:

    The Sims 4/Mods/sims4communitylib.package
    The Sims 4/Mods/sims4communitylib.ts4script



  • Q: S4CL is throwing a ton of errors in my game! Can you fix it??
    • A: S4CL can catch errors caused by other mods. It is extremely rare that S4CL itself is the one breaking.
  • Q: Is S4CL compatible with X???
    • A: S4CL is compatible with ALL mods, it is intended to be an extension of The Sims 4 and not replace functionality of it.
  • Q: I don't want to use S4CL because it contains Adult Content!!
    • A: S4CL does not contain any adult content whatsoever. It may be available on Sites that permit Adult Content, however it does contain any adult content itself.




Usage (For Mod Authors):


A nifty tutorial has been created on the Github Wiki to help those wishing to either get into modding The Sims 4 or to begin utilizing S4CL, you may find it here

I had no problems with this at all - honestly, the only reason I write this review is to counteract the 1-star, as I feel like that is a troll account!

This mod is essential, I really like how easy it is to use. ColNutty made a rock-solid mod.

downloading this mod broke my downloads folder. it won't open anymore.

Response from the author:

Define "broke my downloads folder", because this API does not make any modifications to the game and thus would not "break your downloads folder". Did you mean your mods folder?
