What are these objects
? Are they all the same kind of object? If so, I'd recommend that you place them all in some "container" node in your scene, which will make them easy to find and update via a script. For example, if all of the objects are Label
nodes, you could create your scene like this:
CanvasLayer (or whatever the root node is)
LabelContainer
Label1
Label2
Label3
Label4
Then, in a script attached to the root node, something like this:
func _ready():
for child in $LabelContainer.get_children(): # get each child control
if child is Label: # if this child is a Label...
child.text = "your text here" # update it's text to whatever...
