2 Questions...

Okay I have to questions that I need for my map, please answer :D:
1. Is it possible to make food usable like gold?
2. The second question is, how do I make it so that a person is able to BUY spells like in the TGS (The Great Strategy)???

I Think the answere 2 the 2nd 1 is yes, make a blank item then (Depending on what item it is) Give the buying unit the spell

1. Yes, you'd have alot of changing of things to do though.

2. Setup a trigger so that when a hero acquires an item(how much food it cost can be determined in object editor), that the ability is added to that hero.

As for the food thing, you can just create a reverse food system, see, gold you use and it decreases, you get more of it. Food you use it and it increases, you get less of it. And food can also be changed using triggers.

So yes, food is usable. It's a rather general answer but that should be enough.

Thanks for your help guys.
