Item attribute, how to detect item

[sestorme]

How do I detect an item in a backpack not associated with the action? Just purely for instance, I use item A(weapon) on item B(something on the ground) and item C(in my backpack) is to be detected. How? Somehow with item ID which is known for me? Any suggestions?

I tried like this, no effect.

doItemSetAttribute(getPlayerItemById(cid, true, 2050), "description", desc)

getPlayerItemById uses pushThing, so you get a table with itemid, uid, actionid and type
you need to call field uid

doItemSetAttribute(getPlayerItemById(cid, true, 2050).uid, "description", desc)

Worked Thanks.
