How do i save a Node and Its children

Question

I'm trying to save a node and its children, but only the Parent is saved:

func save():
    var save = PackedScene.new()
    save.pack(self);

    ResourceSaver.save(save, "res://lista de clientes/JDC.tscn");

There is one step you are missing here to include a nodes children, that would be to set the owner. So using your example code here:

func save():
    var save = PackedScene.new()
    for c in self.get_children():
        c.set_owner(self)
    save.pack(self);

    ResourceSaver.save(save, "res://lista de clientes/JDC.tscn");

Remember to set the owner before you pack it, this will now save itself and it's immediate children. As a side note, if c in this case has children, you will also need to loop through these and set owner to self so the for loop would then become

for c in self.get_children():
            c.set_owner(self)
            for a in c.get_children():
                a.set_owner(self)

Okay, it kinda worked, but when it loads, all the variables were reset to the default

---

if your variable is exported, it will have the appropriate flags set to be saved

Okay, i used the @export thingy on the variables i wanted and it kinda works

But everytime i use it in a array that stores the Nodes inside the parent variable it crashes

It might me because i'm declaring the array wrong

@export var clientes:=[];

Nope, you are declaring it correctly. When I export and use an array, the same one you posted, it seems to save just fine with its children and a random value appended to it just fine. I tried with the node paths and it was fine, as well as getting a node with $ and storing it. Getting the node of course caused an empty entry, but it did not crash.

Could I see the code as you are writing it, so I can try to replicate this crash and if so, help try to find the reason why.

I noticed i was doing an infinite loop inside the object, sorry XD.

But thanks, you were of immense help!!
