Directional Shields ( Deflectors )
Using the discussions on Ablative Armor, it seems relatively straight forward to adapt them to modeling Directional Shields ( ala SFB ) in a Starmada context. So far to date, Ablative Armor has been valued at:
SU Cost: ( Armor Value / HS ) ^ 2 x Original SU
Base DRat: (( 2 / 3 x Armor Value ) + HS ) x 2 x Shield Factor
Given that, a HS 6 ship with an Ablative Armor value of 3 and no shields would use 225 SU for the Armor and have a base DRat of 16.0.
This Ablative Armor stops all damage from 360 degrees. After it is destroyed, damage proceeds on to the Damage Track as normal. So the above ship would take the first three points of damage it received on its Ablative Armor before rolling any additional damage as normal.
Now, couldn't we simply multiply this Ablative Armor by six and assign it to one of the six hex faces surrounding the ship and have it simulate Directional Shields? So the above 3 Ablative Armor could actually represent 18 Shield boxes that would need to be permanently assigned to one of the six facings, say 4/4/2/2 which would represent 4 boxes on the forward (#1) shield, 4 boxes on the #2 and #6, 3 boxes on the #3 and #5, and finally 3 boxes on the rear (#4) shield. Thus any damage that comes in through that facing would first have to destroy those boxes before proceeding onto the Damage Track but the other shield facings would be unaffected and later the ship could maneuver to interpose these undamaged shields.
The shield assignment should take place during the design process and be permanent for that class. Obviously, small ships will have paper thin shields, while HS 20 behemoths will have tons. As there are no conventional Starmada shields to penetrate (or maybe you did equip them?) PEN values become straight multiples to damage, like DMG is. So a 3+ 3/2/2 weapon would have three shots each causing 4 points of damage if/when they hit.
I think that a TL modifier could also be applied so that a race with low tech will have minimal shields while a high tech race would have oodles.
So the final Shield calculations would be:
SU Cost: (( Total Shield Boxes / 6) / HS ) ^ 2 x Original SU
Base DRat: ((( 2 / 3 x ( Total Shield Boxes / 6 )) + HS ) x 2 x original Starmada Shield Factor
This will add an element of maneuver to the game as you try to keep an opponent away from a weakened or down shield. Also to avoid confusion with the existing Starmada Shields, perhaps we should call this type "Deflectors" although the reverse seems more appropriate. Maybe the next version of Starmada will switch the names?
