Their data can be retrieved the same way as from [PackedDataContainer]. [codeblock] var packed = PackedDataContainer.new() packed.pack([1, 2, 3, ["abc", "def"], 4, 5, 6]) for element in packed: if element is PackedDataContainerRef: for subelement in element: print("::", subelement) else: print(element) # Prints: # 1 # 2 # 3 # ::abc # ::def # 4 # 5 # 6 [/codeblock] </description> <tutorials> </tutorials> <methods> <method name="size" qualifiers="const"> <return type="int" /> <description> Returns the size of the packed container (see [method Array.size] and [method Dictionary.size]). </description> </method> </methods> </class>
