Error referencing an Object

Hi,

im trying to make a card game. There is something I can’t understand:

I have a class named HandManagement that has a list of GameObject and a method AddToHand that add to a list (the hand) a gameobject passed through variable (bringing in hand)

I have a Tile GameObject on the screen with a script that, when collides with mousedown:
the variable hand of HandManagement type is called with method AddToHand to add that gameobject to hand (AddToHand(this.gameobject)

When I try unity tells me that the object doesnt exist…
Why?

Thank you

Unity tells you which object doesn’t exist?
Are you getting an error? Please share the code and the exact error message.

My guess is you never assigned your HandManagement reference.
