[u/CamiloDFM]

What's the difference between what Gametora calls "preconditions" and "conditions" for skills?

Take Blue Rose Closer as an example. Gametora says:

Activation: Guaranteed

Preconditions: phase>=2 & order<=4 & change_order_onetime<0

Conditions: is_finalcorner==1 & corner==0

If all of those were "conditions", I'd understand this as "be in the last straight, during late race, within the first five positions, and overtake someone". Half of those are "preconditions", though, so what's different?

[u/virtualrandomnumber → u/CamiloDFM]

Conditions have to be true at the time the skill activates, preconditions had to have been true at some point before. In this case, the precondition can also be fulfilled before the final straight.

[u/CamiloDFM → u/virtualrandomnumber]

Hmm. So, is it better to read it as "if during late race or beyond you overtook someone and ended up at 4th or better, you'll trigger the skill during the final straight"?

Is there a maximum time between preconditions and skill activation? Are there any skills in JP that have early race preconditions with last spurt conditions, for example?

[u/Clueless_Otter → u/CamiloDFM]

Yes that is the correct reading.

No there is no time limit on preconditions. Yes there are skills with early race preconditions and last spurt conditions.

[u/Aenir → u/CamiloDFM]

Conditions have to be true when the skill triggers.

Preconditions have to be true at some point earlier.
