Chemistry: Difference between revisions

This whole section is the reason why the encouragement system is important. Sims with the same zodiac are neutral to each other, thus Sims that have the same exact genetic personality would get high scores here, but would never be beyond 70 points because their zodiacs cancel each other out. To get the amount of points needed for 3-bolt relationships, youSims need to have a pair of signs that have +35 attraction and arebe close in personality. Thus it is far more likely that CAS Sims or playable Sims beyond the first generation that vary from the norm have 3 bolt relationships with their partners. The [[personality]] portion of the attraction score is the most complex easy to mess up.

For those of you who are math-oriented, here are the formulas used: If both qualities are on the same side of the scale (6-10 or 0-4) there is a '''bonus''' of 7 - (difference / 71). Note that 5 is excluded, although not when both sims have 5 points for that quality pair. If they are on opposite sides of the scale (say one is grouchy while the other is nice), there is a '''penalty''' of (difference between simSim and 5)/71 for each simSim added together.

If you don't especially care to track down every stray decimal, the following is a chart of estimated values based on personality points. Again, note that if the personality is on the same side of the scale, you use the first chart. If they are on opposite sides or one is 5, then use the second chart. When using the Penalty chart, you find the penalty for each simSim and add them. If the combined penalty is less than -7, it becomes -7.

With ''[[FreeTime]]'', Sims can wish for Beauty from the [[Genie#The Sims 2|genie]], which sets the attraction score to a flat +100 for all relationships he or she has with other Sims. This modification is actually set first and, if true, the rest of the calculations and effects are skipped. This means that if youa wishedSim forwho Beautyhad andan thenactive wish for Beauty took a love potion, the love potion would be nulled until the Beauty wore off, which would resultresulting in a wasted love potion.

If two Sims with negative chemistry are married, engaged, going steady, in love, crushing, or develop a long term [[relationship]] of at least 70, their chemistry points will be increased to zero the next time they interact face-to-face. Although the total attraction is an average of individual attractions, if either individual Sim has an attraction toward the other of < -25, then the final averaged attraction score will be adjusted by -50. Note that both of these modifications are done after finding the Sims' chemistry fromusing the methods given above and isapplying addedthe onto by themodifying effects described below.
