We don't use that info for anything, and it generates unnecessary diffs every time we bump the minor version (and CI failures if we forget to sync some files from opt-in modules (mono, text_server_fb).

[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].

Packs the given container into a binary representation. The [param value] must be either [Array] or [Dictionary], any other type will result in invalid data error.
|
|
[b]Note:[/b] Subsequent calls to this method will overwrite the existing data.
