I’m trying to get the children of a node and its returning the error message:
“Attempt to call function get_children in base ‘null instance’ on null instance”
The node path is correct and I copied the path directly from node so it doesn’t seem like there is a mistake with that.
Here is the code:
for inv_slot in $InventorySlots.get_children():
inv_slot.connect("gui_input", self, "slot_gui_input", [inv_slot])
And the scene tree looks like this(I don’t know how to upload photos):
Inventory → InventorySlots → Slots 1-25
(The script is attached to the “Inventory” Node)
Is there anyway to fix this?
When I need to acces the all teh childs of a node I do this
for i in Node.get_child_count():
var node = Node.get_child(i)
# do your stuff
Not sure if get_children() does the same? maybe it does. If what I wrote doesnt work, try this please and let me know what is the output:
for i in $InventorySlots.get_child_count():
var node = $InventorySlots.get_child(i)
It output the same error message as before.

but what are the print outputs? for example print($InventorySlots).
If you just do
func _ready(): print($InventorySlots) and it shows the error, then the problem is that godot cant find that node (probably a typo?). Thats why I asked you to show me all the prints, to see where the problem is

When I ran the line it output:
Also it shouldn’t be a typo because I copied the root directly from the node unless the script is being executed in another scene(This scene is the only instance of than script so it shouldn’t be).
print(self.get_children()) to make sure that the InventorySlots node is in fact a child and it output this so I cant seem to find the issue.
