Static STR ALSO applies to Enemy! No decaying to above -75!

Pet is kinda iffy... To say the least...

I used Simlogical's More Realistic Relationship Decay mod for a long time, and after seeing how quicker the relationships decayed regarding pets, I decided to expand upon Inge's mod, shifting the thresholds around and adding more conditions.
This mod helps with both maintaining relationship and segregating how well do Sims know and should treat each other.


General
- Enhances the ability for Sims to remain on good terms with one another via dictating when the STR decay per day should stop
- Sims have a set range of relationship values where their STR will cease decaying, allowing certain status to be kept for life! (Until they antagonize each other.
)
- These status are Best Friend, Love, BFF, Enemy and close relatives.
- For example, the STR scores for any acquaintances remain static from -30 to 30. Therefore, any Sims can take advantage of that to build up their relationship to 30, and keep that value for the rest of their life.
- As they can keep fairly good relationship scores for as long as they live, they may then take advantage of that and become Friends more easily.
- The Best Friend status is for life, as their STR will not drop below 60. Useful for maintaining family friends and various social events. That's is, unless they run afoul of each other!
- Changes to how BFF is earned and preventing it from supplementing Best Friend
- Proper BFF loss on low LTR
- STR decay changes cover both Sims and pets. Pets benefit even moreso.
Next up are specific detail. Long lists and a lot of numbers!

Sims
- STR decay rate is -\+2 per day. (Same as original)
- STR decay rate is -1 per day for Best Friends or better.
- Acquaintances have a broad range where their STR values do not decay: -30 to 30.
- The following status have their STR values cease decaying once values are equal to or less than the specified numbers (more than for negative):
- Enemy: -75.
- Best Friend: 60.
- Love: 75.
- BFF: 90.
- Relative: always static; never climbs up or decays.

Pets
- Pets have a broader range for static STR than Sims: -45 to 60.
- If Sims are Best Friends with pets => Sims' STR to pets will never decay below 75.
- If Sims consider pets as Friends => Pets' STR to Sims will never decay below 75.
- If Sims consider pets as Best Friends => Pets' STR to Sims will never decay below 90.
- STR decay rate for pets is different from Sims: -\+3 per day.
- Packs (dogs only): decay rate is -1\+3 per day, and STR may actually climb up to 75.
- Masters (dogs only): never decreases, and may climb back at +5 per day, up to 90.
- Mine (cats only), never decreases, and may climb back at +4 per day, up to 90.
- Wolves use the same logic as dogs, but do not benefit from the Master status.
BFF Changes
Because BFF status is rather quickly earned after gaining the Best Friend status, I decided to have BFF earned during the relationship decay hour (16:00) - linking them if both Sims' LTRs are 90 or more. Because of the sheer length and sparse sub-functions of the Adjust LTR global, the optional file suppresses earning the BFF status the normal way, and enforce it to only earn during the relationship decay hour.
BFF status is always earned quickly - as soon as the LTRs for both are 90+, they will earn the status in as quickly as half an hour.
BFF status will be lost if the LTR score of either drops below 30, via the same method and at the same hour.

- Either of the Core folder is required.
- The difference is the slower LTR change per day on the 6LTR version.
- BFF changes are within the Optional folder.

These are less of bugs within the mod itself, and more of outside issues I have not yet properly understood. 2 bugs are known:
- University students, at least for dormitory residents who are being played, suffer from magnified STR decay:
- The decay is multiplied by the number of household members. If there are 6 playable members present, then their STRs that can decay will decay at -12 instead of -2. This affects everyone.
- The current solution is to suppress STR decay for all university students.
- To undo the suppression, use SimPE to find BCON: Rel.Decay - University (101D), and change the sole value inside to 0.
- STRs for pets decay unlike the expected amount, such as decaying at -4 per day instead of -2.
Please report any other bugs in the comment section.

This mod is built upon Simlogical's More Realistic Relationship Decay mod, and therefore intended to replace it. It adds and modifies the Controller - Relationship Decay group (0x7FF41B0C) with the following instances:
BCONs:
0x00001000
0x00001001
0x0000101A
0x0000101B
0x0000101C
0x0000101D
BHAVs:
0x00001005
0x00001013
0x00001102
0x00001103
0x00001104
0x00001105
0x00001106
0x0000110A
For the additional files regarding BFF adjustment, they modifies 3 following globals:
BHAVs:
0x0000038F
0x0000060C
0x0000060D

About Me
Mod update logs are always in the comment sections. Bold line indicates an important fix or a big feature. Some updates may be stated to be non-essential.
I prefer to modify and expand upon other people's contents, since I'm no artist. I will ask content creators still active first, but I'd love if they actually ask me to help out. I also like mods and objects that add more to gameplay (and modify them to add even more!) since everybody else has been making fixes.
