Little Question

I have a Question

I want to make

Gold = Copper (Finished)
Wood = Silver (Finished)
Food = Gold

Can i changed that Gold can be added to the "Food" if you found Gold somewhere ?

I'm sure there's a trigger for it. I'm not a big triggerer myself but if you look around you might find something. Sorry I couldn't be more helpful.

Food into Gold... that could be tricky... then again it could be so amazingly easy.
I think the easiest way to do it would be to set a maximum gold (maximum food) with a structure that gives alot of food. Then whenever you gain gold you trigger it so it creates a number of units equal to the amount of gold you found.
These units would have to have a food cost of one, thus increasing your food cost and making it seem you gained more gold.

Of course, there may be a way to change the maximum or current food with triggers, but I've never heard of it.

Hope that helps.
