Component Modding 101

[Iskander]

Well having gotten hooked onto SEIV about 2 sleepless weeks ago, it didn't take me long to get stuck into playing around with modding, what fun..

Bear with me as I describe my thought process, it does lead somewhere.

First I thought lets bring all the ships down to more 'realistic' sizes, but then I remembered that HPs are related to hull size, d'oh, don't quite want to get into redoing all the weapons just yet.
Well at least the semi neutonian physics as per Proportions works as I wanted the system to move.

So now I'm still left with the feeling that more hull size varieties are needed, but I believe we can't add ship sizes to the roster yet?

So then I thought 'Streamlining' is the answer, if we can't reduce physical hull sizes we can simulate it. And for that I came up with a streamline component.
Now I need to know if this is a valid module description that will behave as intended?

Here's the module first tech level and then I'll list my concerns. Maybe someone can shed some light.

Name := Streamlining I
Description := Streamlining the hull decreases supply costs and increases agility.
Pic Num := x
Tonnage Space Taken := 10
Tonnage Structure := 5
Cost Minerals := 100
Cost Organics := 0
Cost Radioactives := 0
Vehicle Type := Ship
Supply Amount Used := -5
Restrictions := None
General Group := Vehicle Control
Family := 2
Roman Numeral := 1
Custom Group := 0
Number of Tech Req := 1
Tech Area Req 1 := Ship Construction
Tech Level Req 1 := 3
Number of Abilities := 1
Ability 1 Type := Combat To Hit Defense Plus
Ability 1 Descr := Gives a 3% defense bonus in combat (only 1 component per ship effective).
Ability 1 Val 1 := 3
Ability 1 Val 2 := 0
Weapon Type := None

First question is the one component per ship rule, does that apply to the ability or the individual components? ie: will it stack with the defensive armor? In fact what if I want to allow more than one of this component?

Will a negative supply amount work?

How does the family number relate to 'show only latest' when designing a ship? Would it be better (if possible) to make a new family of say 'Hull Tech'?

Thanks for taking the time...
