Cutting to the point, it would be a cool idea for parts to be able to change their stats (like buffs) as a result of the ship's various statistics, such as a thruster increasing efficiency as the ship's weight increases. Just a little list of info parts can reference from the ship itself.
Dimensions x, y
Weight w
Crew c
Density d
(ship weight divided by part count)
HP h
(Total HP of all parts)
Avg. HPp
(Total HP divided by part count)
Current Velocity v
(the speed the ship is currently moving at)
You would enter any of these variables x, y, w, c, h, p, d
in place of any number to set that variable to correspond with the ship's information.
Math
Some of you cringed reading that word, don't lie to me.
Basically, you take a variable or value and do math on it, surrounding it in apostrophes or something.
Example
Hp (p*2)
This part would now have twice the average HP of every part on the ship
That sort of thing
Some more variables
Ship Center x and y z, a
(uses the focus center)
Ship Cost l
