Signals from PackedScenes erroring.

[glad mortar]

@export var experience_manager: Node
@export var skill_upgrade_scene1: PackedScene
@export var skill_upgrade_scene2: PackedScene

experience_manager works just fine, but the PackedScenes are throwing an error. Here's what this script does:

func _ready():
    experience_manager.level_up.connect(on_level_up)
    skill_upgrade_scene1.level_up.connect(on_level_up)
    skill_upgrade_scene2.level_up.connect(on_level_up)

And then, all 3 of those exports have this:

signal level_up(new_level: int)

level_up.emit(global.game_data["level"])

The error is seen in the image. But, why? Can you not do this with a PackedScene?

yeah, PackedScenes are resources, so you could use the .instantiate() method to create an actual Node, then add it do the scene tree with an add_child call. lmk if that works!

Ah, but these nodes would already exist, I wouldn't want to create them again. Honestly, it's good enough to know that I can't use a PackedScene. I'll have to look for another workaround method.

if the nodes already exist, then what's the issue?

Actually, good point. I'm approaching this all wrong.

Sometimes just need someone to say "aren't you forgetting something?" to be like "oh yeah!". Thank you.
