This simplifies #12467.
Using a tree-exclusive amor type is far more efficient
than adding more warheads, which cost performance
due to their huge Spread
This also restores the 100% efficiency vs. trees for
some of the incendiary nuke warheads (which have
reduced efficiency vs. Wood since #13643).
Note: Atomic had two tree-only warheads with a Delay
of 15, I believe the first one to be a copy-paste error
and moved the damage to the regular SpreadDamage
with a Delay of 10.
penev discovered that the RulesetLoaded functions of projectiles were
never being called, meaning that their blocking calculations were not
properly accounting for actors with large hitboxes.
The best fix for this is to change FindActorsOnLine to always account
for the largest actor's hit radius, rather than forcing callers to pass
the largest radius. Per the comment in Util.cs, as a result, move this
computation to ActorMap. I decided to simplify by not making a separate
calculation for actors that block projectiles only; this may cause a
small performance degradation as the search space is a bit larger.
Similarly to this, I've removed the ability to specify a search radius
manually. Because this is only a search radius, setting a value smaller
than the largest eligible actor makes no sense; that would lead to
completely inconsistent blocking. Setting a larger value, on the other
hand, would make no difference.
CreateEffectWarhead was the only place in core code any of these search
radii were set, and that's because 0 was a mysterious magic value that
made the warhead incapable of hitting actors. I replaced it with a
boolean flag that more clearly indicates the actual behaviour.
Fixes#14151.
On bleed, both the explosion as well as the water splash warhead of weapons triggered on bridges, since they have both the Ground and Water target types.
Ground cannot be made invalid for water splashes without causing regressions elsewhere, so a new Bridge target type is introduced to explicitly make bridges invalid targets for water splash effect warheads.
Also walls, trees and husks in most cases.
Note: Differences between warheads are intentional.
Note2: Some smudge WHs were removed instead when the weapon was purely anti-air or anti-water.
Renamed RA UnitExplode to AmmoExplode, added new UnitExplode with 1/10
damage.
Reduced TD UnitExplode damage to 1/10 of old value.
Now artillery always explodes, but there's only a 75% chance it explodes
violently and only when it has ammo.
If either condition isn't met, it explodes with the (now less violent) UnitExplode.
