Requirements
This mod requires The Sims 3: Generations and The Sims 3: Seasons.
Writing Letters
The “Write Letter to…" and “Write Hate Mail to…” interactions work similar to the “Send Love Letter to...” interaction from The Sims 3: Seasons, but no actual letter is sent.
Child and older sims can write letters or hate mail to people they know in town! Writing letters will give a small relationship boost (similar to texting), while hate mail will do the opposite and reduce their relationship.
Young Adults and older will use the “Write Thank You Notes” animation from The Sims 3: Generations, while Child and Teen sims use the homework animations.
Small note that the homework notebook doesn't appear when a Child or Teen sim is writing a letter, but the interaction works fine.
Tuning
All of the following values are tunable in the mod’s XML files.
kFriendlyLetterLTR = 10
kMeanLetterLTR = 10
Conflicts & Known Issues
This is a new script mod so there shouldn’t be any conflicts.
Credits
EA/Maxis for The Sims 3, Visual Studio 2019, ILSpy, s3pe, Notepad++, deathbypufferfish on Tumblr for extracting the TS4 icons, and Around The Sims 3 for her letter/envelope textures.
