[General] Event unit is selected and un-selected by Select User (by Marketplace)

[redivider]

I'm trying to detect the event where that a unit is selected/un-selected by Select User from, example Marketplace. Is there any way to do it? Tks for helping.

If you can't detect it from an ability cast then try using orders. A unit issued an order targeting an object -> Order = whatever the select user order is -> Do stuff.

Dunno if you can detect Unselecting units. It's probably possible with a more complex system, something like keeping track of who has been selected by the marketplace and then keeping an eye on that unit periodically to see if it's still selected/near the market.
