yeah thats what I did too. Added that line, made her a little bit faster but a little bit weaker in terms of hull.. and gave her a 0.01 possible spawn rate for pirates
Changing the stats for a pirate version should not be necessary, it's done automatically according to code near the top of "Ships_init.c". Pirate ships should already get 10% extra speed and turn rate, and 20% less HP. (And also more crew and less weight.) It also means that if the ship is assigned to Spain then it will get the Spanish modifiers instead. Why would it be assigned to Spain? Because the
Silent Mary in "Salazar's Revenge" is a variant of the
Couronne, black/red is a suitable colour scheme for Spain, so this ship could represent the
Silent Mary before it was cursed - not an exact match but better than the normal "FR_Couronne".
You'll probably also need to edit "InternalSettings.h" to change MAXPIRATECLASS, currently set by default to 4, which means the tier 2 "Couronne_pirate" won't show up in a pirate group even if you set its spawn rate to 1.0.
Unless Maelstrom handles both national modifiers and ship spawn probabilities differently from NH, that is...
Meanwhile, I've got the ship working in NH:
I've also made a new texture file so that the yardarms match the black masts:
And this is the ship pretending to be the uncursed
Silent Mary:
Spanish flags on the masts and the eagle emblem of the Holy Roman Empire on the sails.
