I've been tinkering with creating new leader traits and would like to (among others) create a seafaring trait. I'd like it to provide two advantages: +1 unit speed for naval units and +1 food on clams, crabs, fish, and whales when using fishing/whaling boats. The +1 unit speed for naval units is pretty easy... just give the Navigation I promotion for free to naval units.

The +1 food from sea-based resources is the one I'm having a problem with. I can't see a way to do this in the XML and I'm guessing this is going to require python scripting to make it work. Can anyone give me any suggestions on where to look? A code-snippet to insert would be a godsend!

I already made a seafaring trait, and there is a link to it in my sig.

That was my inspiration. I saw your mod and started working on a series of new leader traits. The problem I ran into was that the +1 movement bonus for ships is a fairly light bonus compared to the standard traits. If I can improve it to bring it level with the others, I'll do the playtesting on it and release the set of new leader traits as a mod.

ok, well I was planing on making more traits, but I've been working on learning how to make a new civ, for the california project

Very cool... the ones I've created at this point are:

Seafaring (Naval units get the Navigation and Flanking promotions)
Agricultural (Any square that produces 3 or more food gets a +1 bonus)
Educated (10% bonus to research)
Mercantile (25% bonus to trade route values)
Defensive (Archer and Gunpowder units get City Garrison I promotion)
Productive (Any square that produces 3 or more production gets a +1 bonus)
Raider (Melee, Siege, and Armor units get City Raider I promotion)
Nomadic (Cavalry and Armor units get a +1 to move)

I'm currently using these to assign a third leader trait to each leader such that each leader gets two traits from the standard set and one new trait from the above list. Once I've done that, I'll start playtesting and making adjustments.

nice job, wanna work on this together? In my tread, I had a guy suggest something like defensive, only it was called stalwart, I like that name better.

oh, and I am also trying to figure out how to get it so that each trait has an aditional starting unit.
