glTF node class.

</brief_description>

<description>
|
|
Represents a glTF node. glTF nodes may have names, transforms, children (other glTF nodes), and more specialized properties (represented by their own classes).
|
|
glTF nodes generally exist inside of [GLTFState] which represents all data of a glTF file. Most of GLTFNode's properties are indices of other data in the glTF file. You can extend a glTF node with additional properties by using [method get_additional_data] and [method set_additional_data].

Gets additional arbitrary data in this [GLTFNode] instance. This can be used to keep per-node 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.

Sets additional arbitrary data in this [GLTFNode] instance. This can be used to keep per-node state data in [GLTFDocumentExtension] classes, which is important because they are stateless.
|
|
The first argument should be the [GLTFDocumentExtension] name (does not have to match the extension name in the glTF file), and the second argument can be anything you want.

|
<member name="camera" type="int" setter="set_camera" getter="get_camera" default="-1">
|
|
If this glTF node is a camera, the index of the [GLTFCamera] in the [GLTFState] that describes the camera's properties. If -1, this node is not a camera.
|
|
</member>
|
|
<member name="children" type="PackedInt32Array" setter="set_children" getter="get_children" default="PackedInt32Array()">
|
|
The indices of the child nodes in the [GLTFState]. If this glTF node has no children, this will be an empty array.
|
|
</member>
|
|
<member name="height" type="int" setter="set_height" getter="get_height" default="-1">
|
|
How deep into the node hierarchy this node is. A root node will have a height of 0, its children will have a height of 1, and so on. If -1, the height has not been calculated.
|
|
</member>
|
|
<member name="light" type="int" setter="set_light" getter="get_light" default="-1">
|
|
If this glTF node is a light, the index of the [GLTFLight] in the [GLTFState] that describes the light's properties. If -1, this node is not a light.
|
|
</member>
|
|
<member name="mesh" type="int" setter="set_mesh" getter="get_mesh" default="-1">
|
|
If this glTF node is a mesh, the index of the [GLTFMesh] in the [GLTFState] that describes the mesh's properties. If -1, this node is not a mesh.
|
|
</member>
|
|
<member name="original_name" type="String" setter="set_original_name" getter="get_original_name" default="""">
|
|
The original name of the node.
|
|
</member>
|
|
<member name="parent" type="int" setter="set_parent" getter="get_parent" default="-1">
|
|
The index of the parent node in the [GLTFState]. If -1, this node is a root node.
|
|
</member>
|
|
<member name="position" type="Vector3" setter="set_position" getter="get_position" default="Vector3(0, 0, 0)">
|
|
The position of the glTF node relative to its parent.
|
|
</member>
|
|
<member name="rotation" type="Quaternion" setter="set_rotation" getter="get_rotation" default="Quaternion(0, 0, 0, 1)">
|
|
The rotation of the glTF node relative to its parent.
|
|
</member>
|
|
<member name="scale" type="Vector3" setter="set_scale" getter="get_scale" default="Vector3(1, 1, 1)">
|
|
The scale of the glTF node relative to its parent.
|
|
</member>
|
|
<member name="skeleton" type="int" setter="set_skeleton" getter="get_skeleton" default="-1">
|
|
If this glTF node has a skeleton, the index of the [GLTFSkeleton] in the [GLTFState] that describes the skeleton's properties. If -1, this node does not have a skeleton.
|
|
</member>
|
|
<member name="skin" type="int" setter="set_skin" getter="get_skin" default="-1">
|
|
If this glTF node has a skin, the index of the [GLTFSkin] in the [GLTFState] that describes the skin's properties. If -1, this node does not have a skin.
|
|
</member>
|
|
<member name="xform" type="Transform3D" setter="set_xform" getter="get_xform" default="Transform3D(1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0)">
|
|
The transform of the glTF node relative to its parent. This property is usually unused since the position, rotation, and scale properties are preferred.
