Fix Deadline Immortality (Revised)

[K1CE]

##what
This fixes the orbital unit's inability to be destroyed.
Currently, Deadline is indestructible upon being built. This is in contrast to how the other satellite artillery from UEF functions where it can be taken down by destroying the central command building.

##why
It makes it impossible for games started in 'Annihilation' gamemode (which requires every enemy unit to be destroyed) to end.

##how
All Deadlines are destroyed in the OnKilled event of Countdown as long as there are no other Countdowns.

• You can use the unit's blueprint id (which is lowercase) as a category
• FAF adds Unit.Brain as a quicker replacement for Unit:GetAIBrain()
• FAF adds Unit.Dead to check death status. For this station, it will be set to true in the OnKilled you called earlier. For other stations, we have to check it just in case multiple stations die at the same time and a different station exists as a unit but is in its death animation (the entity ID check doesn't work for that case).

Suggested change

	--Destroy all orbital on Countdown's death
	local units = self:GetAIBrain():GetListOfUnits(categories.EXPERIMENTAL, false, false)
	local toRemove = {}
	for i, unit in ipairs(units) do
	local name = unit:GetBlueprint().General.UnitName
	--abort if another Countdown still exists
	if unit:GetUnitId() == "xnb2302" and unit:GetEntityId() ~= self:GetEntityId() then return end
	if unit:GetUnitId() == "xno2302" then
	toRemove[i] = unit
	end
	end
	for _, unit in pairs(toRemove) do
	unit:Kill()
	end
	-- If no other Countdowns exist, kill all Deadline satellites
	local brain = self.Brain
	local stations = brain:GetListOfUnits(categories.xnb2302, false, true)
	for _, station in stations do
	if not station.Dead then
	return
	end
	end
	local satellites = brain:GetListOfUnits(categories.xno2302, false, true)
	for _, satellite in satellites do
	satellite:Kill()
	end

The satellites cost a lot, so maybe it can be more fun to disable their weapons, movement, and selectability once all stations are dead. You would also have to handle re-enabling all satellites once a station is rebuilt.

satellite:SetAllWeaponsEnabled(false)
satellite:SetUnSelectable(true)
satellite:SetImmobile(true)
