Most basic 3D game object, parent of all 3D-related nodes.
</brief_description>
<description>
Most basic 3D game object, with a 3D [Transform] and visibility settings. All other 3D game objects inherit from Spatial. Use [Spatial] as a parent node to move, scale, rotate and show/hide children in a 3D project.
Affine operations (rotate, scale, translate) happen in parent's local coordinate system, unless the [Spatial] object is set as top-level. Affine operations in this coordinate system correspond to direct affine operations on the [Spatial]'s transform. The word local below refers to this coordinate system. The coordinate system that is attached to the [Spatial] object itself is referred to as object-local coordinate system.
[b]Note:[/b] Unless otherwise specified, all methods that have angle parameters must have angles specified as [i]radians[/i]. To convert degrees to radians, use [method @GDScript.deg2rad].
Forces the transform to update. Transform changes in physics are not instant for performance reasons. Transforms are accumulated and then set. Use this if you need an up-to-date transform when doing physics operations.
When using physics interpolation, there will be circumstances in which you want to know the interpolated (displayed) transform of a node rather than the standard transform (which may only be accurate to the most recent physics tick).
This is particularly important for frame-based operations that take place in [method Node._process], rather than [method Node._physics_process]. Examples include [Camera]s focusing on a node, or finding where to fire lasers from on a frame rather than physics tick.
Rotates the global (world) transformation around axis, a unit [Vector3], by specified angle in radians. The rotation axis is in global coordinate system.

<methodname="global_scale">
<returntype="void"/>
<argumentindex="0"name="scale"type="Vector3"/>
<description>

</description>
</method>

</description>
</method>
<methodname="hide">
<returntype="void"/>
<description>
Disables rendering of this node. Changes [member visible] to [code]false[/code].
Returns [code]true[/code] if the node is present in the [SceneTree], its [member visible] property is [code]true[/code] and all its ancestors are also visible. If any ancestor is hidden, this node will not be visible in the scene tree.
Rotates the node so that the local forward axis (-Z) points toward the [code]target[/code] position.
The local up axis (+Y) points as close to the [code]up[/code] vector as possible while staying perpendicular to the local forward axis. The resulting transform is orthogonal, and the scale is preserved. Non-uniform scaling may not work correctly.
The [code]target[/code] position cannot be the same as the node's position, the [code]up[/code] vector cannot be zero, and the direction from the node's position to the [code]target[/code] vector cannot be parallel to the [code]up[/code] vector.
Operations take place in global space.

<description>
Changes the node's position by the given offset [Vector3] in local space.
Rotation part of the global transformation in radians, specified in terms of YXZ-Euler angles in the format (X angle, Y angle, Z angle).
[b]Note:[/b] In the mathematical sense, rotation is a matrix and not a vector. The three Euler angles, which are the three independent parameters of the Euler-angle parametrization of the rotation matrix, are stored in a [Vector3] data structure not because the rotation is a vector, but only because [Vector3] exists as a convenient data-structure to store 3 floating-point numbers. Therefore, applying affine operations on the rotation "vector" is not meaningful.
Determines the threshold distance at which this node will be shown or hidden when this node is parented by a [LOD] node.
For example, a first child with a range of [code]2[/code] will be shown from distance 0 to 2. A second child with a range of [code]5[/code] will be shown from distance 2 to 7, etc.
The merging mode determines whether merging features of the engine ([MergeGroup] and [RoomManager]) will attempt to operate on branches of the scene tree.
The default mode inherited from the scene tree root is [constant MERGING_MODE_ON].
[b]Note:[/b] Merging mode determines whether the merging is [b]allowed[/b] to be performed. It does not guarantee that merging will occur, which depends on whether there are suitable matching objects.
Rotation part of the local transformation in radians, specified in terms of YXZ-Euler angles in the format (X angle, Y angle, Z angle).
[b]Note:[/b] In the mathematical sense, rotation is a matrix and not a vector. The three Euler angles, which are the three independent parameters of the Euler-angle parametrization of the rotation matrix, are stored in a [Vector3] data structure not because the rotation is a vector, but only because [Vector3] exists as a convenient data-structure to store 3 floating-point numbers. Therefore, applying affine operations on the rotation "vector" is not meaningful.
[b]Note:[/b] Mixed negative scales in 3D are not decomposable from the transformation matrix. Due to the way scale is represented with transformation matrices in Godot, the scale values will either be all positive or all negative.
If [code]true[/code], this node is drawn. The node is only visible if all of its ancestors are visible as well (in other words, [method is_visible_in_tree] must return [code]true[/code]).
Spatial nodes receives this notification when their global transform changes. This means that either the current or a parent node changed its transform.
In order for [constant NOTIFICATION_TRANSFORM_CHANGED] to work, users first need to ask for it, with [method set_notify_transform]. The notification is also sent if the node is in the editor context and it has at least one valid gizmo.
