Play With a Stuffed Animal as an Adult
Sims of teenage and above can perform actions on stuffed animals (usually limited to the Childish trait).
Possible commands are "hug", "play", and "cheer up" when happiness is low. No other conversation is possible. Commands issued when in anger are normal.
In order to adjust the balance, we have increased the amount of happiness that rises when hugging and playing, and decreased the amount of happiness that falls over time.
Can be used in conjunction with the infant version above. *There is a conflict, but since the conflicting part is completely the same (change in the amount of reduction in pleasure), there is no problem in operation.
If you still feel that the pace of declining happiness is fast (or slow), use Sims4Studio, etc., and rewrite the number (0.04) before <!-- Default is 0.06 --> near line 13 of Commodity_StuffedAnimal_Love . If you are also using the infant version, change it as well.
