The Silent Architecture of Simlish: An Essay on Language Strings in The Sims 4
Risks & Mitigations
- Risk: Delays from asset owners providing context — Mitigation: Require context in pull request checklist.
- Risk: Inconsistent source strings introduced by rapid content patches — Mitigation: CI gating on localization lint rules.
The Sims 4 uses "string tables" (STBL files) to store and manage all text displayed in-game, from interaction names to notification pop-ups
ModName_Category_Object_Action
The File Path
On Windows, the English string tables are typically located in:
C:\Program Files (x86)\Origin Games\The Sims 4\Data\Client\Strings_ENG_US.package
- Always include a default (EN-US) string. The game crashes or glitches if it cannot find a fallback language.
- Use a unique naming convention. Don't just call your mod
NewTrait.package. Use [ModName]_Strings.package.
- Leave the "FNV64 Hash" alone. When you type a new string into S4S, it automatically generates a Hash key. Do not manually edit this key, or you will break every save file that uses the old version.
- Create "Translation Packs." Release your core mod with only EN-US, then release separate
.package files for FR, DE, ES, etc. This keeps file sizes small for users who only need one language.
