Subject: [PATCH] Configurable LootPool luck formula
|
|
|
|
Rewrites the Vanilla luck application formula so that luck can be
|
|
applied to items that do not have any quality defined.
|
|
|
|
See: https://luckformula.emc.gs for data and details
|
|
-----------
|
|
|
|
The rough summary is:
|
|
My goal was that in a pool, when luck was applied, the pool
|
|
rebalances so the percentages for bigger items is
|
|
lowered and smaller items is boosted.
|
|
|
|
Do this by boosting and then reducing the weight value,
|
|
so that larger numbers are penalized more than smaller numbers.
|
|
resulting in a larger reduction of entries for more common
|
|
items than the reduction on small weights,
|
|
giving smaller weights more of a chance
|
|
|
|
-----------
|
|
|
|
This work kind of obsoletes quality, but quality would be useful
|
|
for 2 items with same weight that you want luck to impact
|
|
in varying directions.
|
|
|
|
Fishing still falls into that as the weights are closer, so luck
|
|
will invalidate junk more.
|
|
|
|
This change will result in some major changes to fishing formulas.
|
|
|
|
-----------
|
|
|
|
I would love to see this change in Vanilla, so Mojang please pull :)
