Item selected detection

[micca]

How do I detect whether an item is selected by a player?

I need to display some custom values of an item, so I assume this would be the easiest way.

AFAIK you can’t do this. Items don’t fire selection events and you can’t enumerate items currently selected by player.

That's sad, they should add this And also variables of item groups and destructible groups.

What's the context? There may be an alternative approach for whatever it is you're trying to implement.

You could create a dummy unit at the position of the item and then make a trigger that detects whenever that unit is selected?

Or, if you want a better method, you can use Trackables : How to: Use Trackables

Unless they added the functionality, trackables can’t be destroyed and they can’t be moved (never any naives for this), so while it sounds attractive this is probably a subpar solution as it permanently uses memory every time you create one. They were likely meant to be superseded by the new mouseclick/location natives. Which could also work for this if you want to ignore drag selecting an item (can you even do that?) and feel like calculating the coordinates of the click based on camera angles.

It was possible before 1.31 and it was implemented in my MWS map (combined usage of EnableSelect, SelectUnit, BlzGetTriggerPlayerMouseX/Y and dummy units)
But in 1.31 they changed EnableSelect behavior, so it's broken now (kinda works, but far from perfection).
