Detect unit giving item to another unit?

[Jonnycakes]

I am working on an item stacking trigger, and it works pretty well so far-items stack even if a unit's inventory is full. This is achieved through using dummy powerup items to replace the real items when they are on the ground. One problem arises when trying to give items to another unit-the item being transferred is not a powerup and it says the hero's inventory is full. Is there a way around this?

Question 2 is the big problem. When a hero drops a 'real' item, the item needs to be replaced with a dummy. The event EVENT_PLAYER_UNIT_DROP_ITEM also registers when a unit sells an item (or loses an item for any reason I am guessing). Is there a way to distinguish between when a unit is pawning and dropping an item?

Problem 1: I think not. Only if you could force a dummy ability for the target X instead of the drop item X.

Problem 2: What about interpreting the orders the unit gets? Or check if the "dropped" item still exists = not sold.

1. Yeah, this actually isn't an order here...
(Using Azlier's PrintOrders gave no result, not even when the unit moves to the other unit which it will give the item too...)

Yeah I was afraid there wasn't a way for giving items between units...for selling, I tried checking if the item exists, but I think the trigger runs before the item is removed, so I will have to use a timer that expires in .01 seconds or something. Thanks!
