How can I prevent the purchase of an item if...

[SutinG]

Hi,
I need to prevent the purchase of an item if the buying hero hasn't some 'X' item... Is this possible? I've seen something like that in DotA.
Currently I'm checking this with a trigger and that returns the gold if is necessary, but this isn't a very fancy solution...

Thanks in advance.
Oh I almost forget.. Happy new year!

Create an upgrade named after your item that needs an item [going to call it item 1], then if the hero buys the needed item [going to call it item 2] set upgrade level to 1, if he loses item 2 set it to 0, add the tech tree to your items requirements.

Thanks Dameon, but I've already tried that and it doesn't work... I can buy the item without any restriction.

Ahh that's right u need to own the shop for that to work. only other thing I can think of is don't add the 2nd item to the shop, when the hero selects the shop check to see if he has the item, if he does add the 2nd item to the shops inventory with 1 max charge, this way the item wont even show up unless you have the first item you need.
