I'm having problems using this. Not sure if I might be using it the wrong way!
I create a new Sprite (Sprite1).
Add the behaviour "Nickname".
Copy the object (now having 2 instances of it in the layout, both with the "Name" of "Sprite1").
The first one i "Nickname": "button_1" and the second: "button_2".
Then i select the action: "Pick matched instances" and enter "button_1" as the nickname to be matched.
Then i select the action to set visibility of "Sprite1" to invisible.
Run the preview.
Both of them are invisible.
Is this intended behaviour?
Thank you, rexrainbow
