Detecting not enough gold

[HungryHusky]

Hi. Is there anyway to detect via triggers when a unit tries to purchase an item but don't have enough gold?
Or would I have to make a custom price and purchase system entirely?

EDIT: The only way i can think of is to make an event "A unit is issued an order targeting an object", Condition "Issued order equal to <order string for (trying?) to purchase an item>".

But for this I would need the order string for a unit trying to purchasing an item. Anyone know how I can find this string?

If you find a way, then tell me. I don't know there is any method to get this "try" to buy an item. :S

I think it's the name of unit, but I'm not sure.

I tried detecting the order id by a jass script I found by displaying the order id when any order is given, but no order id is displayed when trying to purchase an item but dont having enough gold.
However, when I DID have enough gold I discovered that there is a different order id for each item in the shop... <.<

I think it's the name of unit, but I'm not sure.

That what is the name of the unit? The id or the string?
I think id can only consist of numbers no?

Yes if you successfully buy an item, the OrderId should equal the ItemType, (ItemTypes are integers)

but when you only try to buy one, there is no OrderId. (not enough gold/full inventory)

Yeah, this is because the buying action never occurs. It's like trying to use a spell with no mana, the same thing happens. The only way you can detect it is to trigger it by yourself, unfortunately.

For custom vendor systems I always use an item's Life as price. An item's Life can be called in triggers and frankly, I have never run into a problem involving an item's Life.
