SAM

Flag:	SAM
File(s):	Rules(md).ini
Values:	Boolean values: yes or no, true or false, 1 or 0
Default:	no
Applicable to:	BuildingTypes

Can be set to yes in order to restrict a defensive structure to being a SAM (surface to air missile launcher) site. When enabled, the weapons can only fire at aircraft and not at hovering/flying vehicles, nor at airborne infantry.

NOTE: this is unused in Red Alert 2 as the use of this means that the structure will not fire InfantryTypes,VehicleTypes with JumpJet=yes set or acquire them as targets - it will only target AircraftTypes.

---

(For YR only) Because the SAM tag has many limitations If you want give BuildingTypes (AA Tower) The fake SAM=yes effect can be used
I recommend that you use the Natural=yes tag for BuildingTypes (AA Tower) And use the tag Unnatural=yes for InfantryTypes,VehicleTypes,AircraftTypes All that can fly.

Note

This is unused in Red Alert 2 as the use of this means that the structure will not fire InfantryTypes,VehicleTypes with JumpJet=yes set or acquire them as targets - it will only target AircraftTypes.

Aircraft designated as targets must not exist in the [General]►PadAircraft list;

• otherwise, the SAM will not even aim.

Aircraft designated as targets cannot have a valid building in their Dock list;

• otherwise, the SAM can only rotate its turret but cannot actually fire.

However, even so, the SAM can only fire its weapons normally when the target aircraft is in a hover state. Once the aircraft moves, it will only occasionally fire a few shots under specific conditions and the frequency of re-locking and turret rotation in this case does not adhere to the weapon's ROF settings, nor is it a fixed value. Even the aforementioned situation of suddenly firing two rounds can occur without facing the target, even if there is no [Weapon] > OmniFire=yes. Additionally, SAM enforces attacks only on aerial targets, meaning it cannot fire at targets that have landed on the ground, even if they do not have LandTargeting=1.

In other words, SAM targets can only be Aircraft that have AirportBound=yes, Dock=none, and have taken off.
Currently measured:
In the YR1.001+Ares3.0p1+PhobosBuild#45 environment
it is functioning normally.
In the YR1.001+Ares3.0p1+KratosPPv0.1.15 environment
the SAM building will be prohibited from acquiring targets

• (the author of KratosPP stated that this part was not modified at all, and the author does not understand this logic either).
  

In the YR1.001+Ares3.0p1+PhobosBuild#45+KratosPPv0.1.15 environment
the SAM can acquire targets normally
but firing will immediately trigger a Fatal Error, and the EIP address is not in gamemd.exe (the record doesn't really mean much, hence it's not included in the EIP page.).
