+ Efficiently packs and serializes [Array] or [Dictionary].
</brief_description>
<description>
+ [PackedDataContainer] can be used to efficiently store data from untyped containers. The data is packed into raw bytes and can be saved to file. Only [Array] and [Dictionary] can be stored this way.
+ You can retrieve the data by iterating on the container, which will work as if iterating on the packed data itself. If the packed container is a [Dictionary], the data can be retrieved by key names ([String]/[StringName] only).
+ [codeblock]
+ var data = { "key": "value", "another_key": 123, "lock": Vector2() }
+ var packed = PackedDataContainer.new()
+ packed.pack(data)
+ ResourceSaver.save(packed, "packed_data.res")
+ [/codeblock]
+ [codeblock]
+ var container = load("packed_data.res")
+ for key in container:
+ prints(key, container[key])
+
+ # Prints:
+ # key value
+ # lock (0, 0)
+ # another_key 123
+ [/codeblock]
+ Nested containers will be packed recursively. While iterating, they will be returned as [PackedDataContainerRef].
