I don't think that will do what I want, in this instance.

My plan was part of the development of Neutrals with unique and tradable abilities.

What I wanted to do was make a ship training component, which added experience points only when "activated" and worked only for one turn (and then was destroyed)
So you would move the ship into position, with any ships you wanted to train, then crack open the component and let the training flood out...

I have tried mucking about with negative numbers and so on, but I think this is impossible to do.
