@plixel @Rodeo if the parent is creating the children at runtime then that's the time to connect signals in code.
If the child already exists as part of the parent's scene you could connect it's signals in the editor (built-in signals or your own signals). Then in code just run singal_name.emit(args) when needed. You can still connect them in code if you want [e.g. iterate over get_children()].
