Check if a player is about to use an item

[Choppa]

Is there anyway, anyway at all to check if a player has clicked an item, like say with Lightening Shield, it's in your inventory, then you click it, and then you choose a unit to cast it on, but is there anyway to be able to check if the player has clicked the item but hasn't used it on a unit yet?

No. However you can detect when the unit is ordered to use it, which triggers before the unit actually uses it, if that's any help.

How's that done? With

Unit - A unit [COLOR="Blue"]uses an item[/COLOR]

???

EDIT: Nevermind, i've done what I wanted to do :>:> =D =D
