Attack and damage technos under ground

[TaranDahl]

Attack technos underground

• Now, you can enable projectiles to attack technos underground.
  • To actually damage the technos, you need AffectsUnderground.

In rulesmd.ini:

[SOMEPROJECTILE]      ; Projectile
AU=false              ; boolean

Damage technos underground

• Now you can make the warhead damage technos underground!
  • To allow weapons to target underground technos, you need AU.
• Notice that if the projectile detonates underground, its animation effect may look strange.
  • You can use [SOMEWARHEAD] -> PlayAnimUnderground=false to prevent the warhead animation from playing when the projectile detonates underground.
  • You can also use [SOMEWARHEAD] -> PlayAnimAboveSurface=true to make the warhead animation play on the ground directly above when the projectile detonates underground.

In rulesmd.ini:

[SOMEWARHEAD]                         ; WarheadType
AffectsUnderground=false              ; boolean
PlayAnimUnderground=true              ; boolean
PlayAnimAboveSurface=false            ; boolean,

According to our test, only Inviso projectiles can effectively penetrate ground and hit underground units. Others will all explode when impact the ground, while still able to damage underground units if CellSpread is large enough.

This is a hardcoded thing so it's fine to keep it as it is, but it should be noted in the doc.

LGTM

Besides Inviso, maybe only Straight with Trajectory.Straight.SubjectToGround=false and Bombard with Trajectory.Bombard.SubjectToGround=false can hit.

[TaranDahl]

I thought you were planning to add SubjectToGround for other types of trajectories?

[CrimRecya]

Not very accurate. Even after the update, SubjectToGround still only affects the selection of attacking area. Just in Straight and Bombard, because their judgment criteria are simple, allowing them to penetrate the ground will not cause any problems.

You can place these in TechnoExt::ExtData::~ExtData()

	if (this->UndergroundTracked)
		ScenarioExt::Global()->UndergroundTracker.Remove(pThis);

	if (this->SpecialTracked)
		ScenarioExt::Global()->SpecialTracker.Remove(pThis);
