Hello!

Recently i realized, that singleton (Autoload) as a "data manager" will resolve most of my problems in my project. Only problem now is that i dont know how to connect signal from and to Singleton. I tryed to connect it using "node.connect("signal", self, "function_name")", but i dont know how i can get this "node". Probably i searched in wron places, but i didn't find any useful information.

So i'm asking there: How i could connect signal from scene to singleton? is it possible at all? * If it is not possible, how i can realize same actions witout using signals?

I will be very tankful for any information that will help to understand how to solve this problem :)

Your singleton must have a name (let's say DataManager). To connect a signal to it, use the following : DataManager.connect("signal", self, "function_name").

Now i can solve most of problems with singleton and signals. But, just to avoid creating lot of loops in singleton, is there a way to connect signal from scene to singleton? for example: In active scene something happened, and signal with some data has been emited --> Singleton catch this signal, read data from it, make calculations and emit own signal --> Active scene catch signal from signgleton, read signals data, and do things based on incoming data. This is not madatory, but that would be helpful.

May be it will be helpful for someone. Recently i understanded that i can call function in singleton from any point of my game, and it will do same functions as a signal. It will look something like that: In active scene call Singleton function DataManager.compute_something( parametrs ) Singleton function will run function with entered parametrs and send a signal to everyone who needs the result. ( you can also check result from scene, but i think its easyer to do it by using signal ) DataManager.connect( singletonSignal, target, "FunctionInScene" )

It is just a discovery for me, so i describet it there, maybe it will be useful for someone :D
