Thank you, that was my thoughts also, was just asking for clarification.
I'm just thinking that this option could be expanded, and not just true of false, but to something like a name value pairing:
None = All units hit by this unit are killed with a single shot
All:2 = All units hit by this unit receive 2 hit points of damage (any unit with more then 2 hit points will survive).
(if a 'largeArmoredTransport' unit has 2 hit points, and a 'largeArmor' has 2 hit points) Then:
largeArmoredTransport 2:superArmor:1=largeArmoredTransport is killed, but the largeArmor would survive by receiving only a single hit.
Change of thought, maybe 'targetsAA' should be used instead, since that already requires a list of units that can be attacked by this unit. The default for 'targetsAA' would be all 'isAir' units are killed by this unit, otherwise a list of the units that this unit could attack followed by the amount of damage caused, with -1 being kills with a single shot. So using the above :
<option name="targetsAA" value="largeArmoredTransport:-1:largeArmor:1"/>
Then the largeArmordTransport would be killed even if its hit points equaled 3, while the largeArmor would only receive 1 damage.
These are just some thoughts.
