How to make item upgrade system? help?

[kewlthis]

I need system kinda like in battle tanks.

You buy item --> add ability to unit

And i need system that does this:

you click bought item (ability costs gold) --> level of ability increases.

this system will be used in my map: portals. I havent really played around with items so no idea if there is ability that costs gold or something.

• Events
  • Unit - a unit acquires an item
• Conditions
  • level of ability "baaam" for triggering unit equal to 0
  • item being manipulated equal to baaam item
• Actions
  • add ability baaam to triggering unit

• Events
  • Unit - a unit acquires an item
• Conditions
  • level of ability "baaam" for triggering unit bigger than 0
  • item being manipulated equal to baaam item
• Actions
  • set level of baaam for triggering unit = (level of baaam + 1)

baaam is the ability, "baaam item" is the item

baaam is the ability, "baaam item" is the item

but is baam ability that costs gold? is there a way to make that...

the baaam item costs gold, just select the amount of gold in object editor
