Hey newbie question here.

Suppose I have a scene tree like this:

Living
—Animal
---------- Dog
---------- Cat
—Plant
---------- Rose
---------- InsertNameOfAnyPlantHere

where ‘Living’ is the parent of ‘Animal’ and ‘Plant’ and so on.

My question is can a signal emitted by let’s say … ‘Dog’ be received by ‘Living’?
Or can a signal emitted by ‘Plant’ be received by ‘Animal’ or ‘Living’?
If not how can we make sure that the signals can be received?

Mind it that the signals I am talking about are custom made signals in the scripts of the respective nodes.

HELP!

There is no scope for the signals, all the Objects connected to the emitter can be notified of it (in or outside the tree).

ps: with “outside the tree” I mean, it does not need to be a Node attached to the tree, can be a inner Object class in a variable (usually of a Node in the tree).
