How do I pick multiples instances of same object ?

Hello

I would like to know how to pick multiples instances of the same object for using it in the same action

For example :

• I click on a sprite, I save the UID in a variable
• I click on an other instance of the same sprite

How can I check the distance between the two instances of the same sprite ?

The "distance" function is easy to use but with two different object...

Thanks

easiest, would be to have the object in an extra family. ie object player in family "Checker"

tmpUID = 0

on click player

sub event: tmpUID = 0 ?

-action: set tmpUID = player.UID

else

pick all checker

pick checker by evaluate checker.uid = tmpUID

-action: set text to: distance(player.X,player.Y,checker.X,checker.Y)

-action: set tmpUID 0

Nice trick ! Thanks !
