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.

</method>
<methodname="get_global_transform_interpolated">
<returntype="Transform"/>
<description>
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.
Returns the parent [Spatial], or an empty [Object] if no parent exists or parent is not of type [Spatial].
</description>
</method>
<methodname="get_world"qualifiers="const">
<returntype="World"/>
<description>

</method>
<methodname="global_rotate">
<returntype="void"/>
<argumentindex="0"name="axis"type="Vector3"/>
<argumentindex="1"name="angle"type="float"/>
<description>
Rotates the global (world) transformation around axis, a unit [Vector3], by specified angle in radians. The rotation axis is in global coordinate system.
</description>
</method>
<methodname="global_scale">
<returntype="void"/>
<argumentindex="0"name="scale"type="Vector3"/>
<description>

</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 antecedents are also visible. If any antecedent is hidden, this node will not be visible in the scene tree.
</description>
</method>
<methodname="look_at">
<returntype="void"/>
<argumentindex="0"name="target"type="Vector3"/>
<argumentindex="1"name="up"type="Vector3"/>
<description>
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.

<argumentindex="0"name="offset"type="Vector3"/>
<description>
Changes the node's position by the given offset [Vector3].
Note that the translation [code]offset[/code] is affected by the node's scale, so if scaled by e.g. [code](10, 1, 1)[/code], a translation by an offset of [code](2, 0, 0)[/code] would actually add 20 ([code]2 * 10[/code]) to the X coordinate.

</method>
<methodname="translate_object_local">
<returntype="void"/>
<argumentindex="0"name="offset"type="Vector3"/>
<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.

If [code]true[/code], this node is drawn. The node is only visible if all of its antecedents are visible as well (in other words, [method is_visible_in_tree] must return [code]true[/code]).

<signals>
<signalname="gameplay_entered">

Emitted by portal system gameplay monitor when a node enters the gameplay area.

</signal>
<signalname="gameplay_exited">
<description>
Emitted by portal system gameplay monitor when a node exits the gameplay area.
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.
