Question

I’m trying to make a script that duplicated a Package, but the amount that duplicates doubles, and I don’t know why.

func spawnPackage():
	var packagedupe = get_node("/root/Main/Packages/PackageD").duplicate()
	get_node("/root/Main/Packages/PackageD").add_child(packagedupe)
	packagedupe.name = "Package" + str(Packages.size())
	print(packagedupe.name)
	packagedupe.visible = true
	print(packagedupe.visible)
	packagedupe.get_node("CollisionShape3D").disabled = false
	print(packagedupe.get_node("CollisionShape3D").disabled)
	packagedupe.global_position = global_position + Vector3(0, 5, 0)
	print(packagedupe.global_position)
	packagedupe = null

You’re parenting each copy under PackageD:

get_node("/root/Main/Packages/PackageD").add_child(packagedupe)

Next duplicate() copies PackageD and every package already stuck under it, so count doubles each spawn.

Duplicate from a template, parent to Packages (or another folder node), not to the source:

func spawnPackage():
	var template = get_node("/root/Main/Packages/PackageD")
	var packagedupe = template.duplicate()
	get_node("/root/Main/Packages").add_child(packagedupe)
	packagedupe.name = "Package" + str(Packages.size())
	packagedupe.visible = true
	packagedupe.get_node("CollisionShape3D").disabled = false
	packagedupe.global_position = global_position + Vector3(0, 5, 0)

Cleaner long-term suggestion: make a package.tscn and preload(…).instantiate() instead of duplicating a live node.

–Also
packagedupe = null doesn’t free anything ; the node is already in the tree.
