How do I pick the last spawn unit instance?

How do I pick the last spawn unit instance from a Families?

Maybe pick by highest IID

^ Which event should I use to do that?

Another way: every time you spawn a unit update a variable with it's unique id.

variable: latestID[/code:2zaa6yzj]

then

[code:2zaa6yzj]sprite -> onCreated 
               set variable latestID to sprite.UID[/code:2zaa6yzj]

then when you want to pick the latest instance add this to the appropriate event:
[code:2zaa6yzj]
sprite -> pick by unique id [latestID][/code:2zaa6yzj]

thanks

^ Which event should I use to do that?

sorry, the expression is (for a no-variable solution)

System: Pick Sprite by evaluating Sprite.IID = Sprite.Count - 1

thanks a lot

thanks a lot

Or even System: Pick Sprite instance Sprite.count - 1 which is the "Pick nth instance" condition under "System" and does the same as the above.
