If you check Praetorian Industries v1.2a you will find your answer. You need two main components a DETONATOR and EXPLOSIVES:
How To Make a Selfdestructive hull:
1- Detonators:
The role of the detonator is to self destruct the ship as fast as it enters in firing range, or in other words, ship shockwave range. To do this you must use a modded Parasite Flak Cannon. Use the Minefield detonator module as example:
-Operative range: The shockwave radius must be a little bit higher than the maximun firing range, this will guarantee the self damage effect.
-Damage: Always higher than the kamikaze ship combined Armour and Hitpoints, ALWAYS. There are two ways to do this; the first one and potentially OP is to use ships with standard HP values (150-300) but this would result on the complete obliteration of ANY kind of ship inside the detonator range, wich is BAD.
The second one and most realistic is to make a ship with EXTREMELY low Hitpoints… The detonator will have a damage never higher than the highest vainilla fighter HP, then, when the detonator hits a fighter scuad, you MIGHT (not WILL) destroy them, and then your kamikaze ship will explode, causing a larger Shockwave that should take out or damage (may vary depending the EXPLOSIVES specs) any ship inside the detonator max range, or in other words, the ship shockwave range. The armour and shield penetration of the detonator is 100% always.
As i’ve said, the detonator main role is to kill your ship, generating a high damage shockwave, wich is explained below, its secondary role is to damage fighters.
Remember to make the detonator (flak cannon) bullet/bolt FX invisible (veeeeeery small or unexistent at all)
2- Explosives:
Their role is simple, they are the main frigate/cruiser damaging component, composed by a powerful power generator. The power that it generates will be the exact ammount of damage that will deal the shockwave on its strongest moment. The “power generator” will be our explosive, with a power generation value AND a power consumption value, the first one ALWAYS sightly higher than the second one, making it work as a standard power generator but giving an increased shockwave damage to the destroyed hull.
Remember that the total ammount of HP of your hull must be lower than the weakest moment of your DETONATOR shockwave damage, if that doesnt happens, there will be no kamikaze ilusion!
My Praetorian Minefields work exactly in that way, as fast as any ship enters in firing range (or proximity detection range) it “detonates” itself to death, killing or damaging everything around it. You can get different results from using different hull classes.
Remember to use large sprite sized hulls (ie, tiny ship inside a giant sprite of empty space, and compensate it giving to the ship a larger hull size) (this is the reason of why my minefields consume so much pc requeriments, wich is its main flaw…)
