For example, if hero has specialty that provides primary skill bonuses
with "noneOf" limiter that contains limiter that can only be evaluated
in creature context (such as creature level or native terrain), limiter
itself would evaluate to DISCARD, and then will be inverted to ACCEPT by
noneOf limiter. As result, this would give hero bonus to primary skill
even though it is clearly intended to only target creatures.
This introduces NOT_APPLICABLE limiter decision that is not inverted by
noneOf limiter
Fixes Adela specialty that was apparently broken back in #1518 and
replaced with logic that was clearly not tested - it was neither
functional, nor it was following H3 behavior.
- `HAS_ANOTHER_BONUS_LIMITER` now accepts `null` in place of bonus type,
for cases when limiting is needed by bonus source or bonus subtype. This
allows Adela Bless specialty to always work, irregardless of which
bonuses are provided by Bless.
- Implemented `DIVIDE_STACK_LEVEL` updater that functions same as
`TIMES_STACK_LEVEL`, but it divides bonus value, instead of multiplying
it (to make Adela specialty weaker for high-tier units, as in H3)
- Implemented `TIMES_HERO_LEVEL_DIVIDE_STACK_LEVEL` updater that
combines two existing updaters, to implement `val * heroLevel /
unitLevel` formula needed for Adela specialty
- Removed deprecated `ARMY_MOVEMENT` updater. Its functionality has
already been removed in 1.6.X releases, and it was remaining only as a
placeholder
- Updated modding documentation to account for these changes & to remove
some TODO's
Fixed regression from #777 that could led to either duplicated bonuses
or to multiple application of updaters. It introduced double-recursion -
node parents were gathered recursively, and then bonuses were also
collected recursively within each parent. This created situation where
updater could be applied different number of times. For example, hero
bonus that is propagated to unit in combat could be selected directly,
or via hero->combat unit chain, or via hero->garrison unit->combat unit
chains, leading to different calls to updaters if updater handles
garrison unit node type
