How to refer to an object hidden in the scene?

Question

C++ / C#

It is required to refer to an object that is hidden on the stage, tell me how to do this?

Answer 1

I had it so that with a trigger it was necessary to include an object in the hierarchy . I
used this method
//Your object
public GameObject zipnik ;
private void YourEventName(){
// If (your object is not active in the Hierarchy)
if ( ! zipnik.activeInHierarchy ){
//Make your object active(true)
zipnik.SetActive(true);
}
}
