I have a signaling problem that I am not sure how to fix. I have my main scene. Within that scene, I instantiate a child scene. That child scene runs the actions it needs to, and once it is done I need to let the main scene know that it is done. I have function in the child scene that fires once it is done. How to I get the main scene to notice that this function is activated? I tried creating a signal in the child scene, but it only showed the option to connect to nodes within the child scene.
In summary: how do I have an instantiated scene notify its parent scene?
