<brief_description>
|
|
Represents all data of a GLTF file.
|
|
</brief_description>
|
|
<description>
|
|
Contains all nodes and resources of a GLTF file. This is used by [GLTFDocument] as data storage, which allows [GLTFDocument] and all [GLTFDocumentExtension] classes to remain stateless.
|
|
GLTFState can be populated by [GLTFDocument] reading a file or by converting a Godot scene. Then the data can either be used to create a Godot scene or save to a GLTF file. The code that converts to/from a Godot scene can be intercepted at arbitrary points by [GLTFDocumentExtension] classes. This allows for custom data to be stored in the GLTF file or for custom data to be converted to/from Godot nodes.

<param index="1" name="required" type="bool" />
|

<description>
|
|
Appends an extension to the list of extensions used by this GLTF file during serialization. If [param required] is true, the extension will also be added to the list of required extensions. Do not run this in [method GLTFDocumentExtension._export_post], as that stage is too late to add extensions. The final list is sorted alphabetically.

<param index="0" name="data" type="PackedByteArray" />
|

<param index="1" name="deduplication" type="bool" />
|
|
<description>
|
|
Appends the given byte array data to the buffers and creates a [GLTFBufferView] for it. The index of the destination [GLTFBufferView] is returned. If [param deduplication] is true, the buffers will first be searched for duplicate data, otherwise new bytes will always be appended.

<description>
|
|
Gets additional arbitrary data in this [GLTFState] instance. This can be used to keep per-file state data in [GLTFDocumentExtension] classes, which is important because they are stateless.
|
|
The argument should be the [GLTFDocumentExtension] name (does not have to match the extension name in the GLTF file), and the return value can be anything you set. If nothing was set, the return value is null.
