Most basic 3D game object, parent of all 3D-related nodes.
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.
Note: Unless otherwise specified, all methods that have angle parameters must have angles specified as radians. To convert degrees to radians, use @GDScript.deg2rad.

Methods¶
Constants¶
- NOTIFICATION_TRANSFORM_CHANGED = 2000 — 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 NOTIFICATION_TRANSFORM_CHANGED to work, users first need to ask for it, with set_notify_transform.
- NOTIFICATION_ENTER_WORLD = 41 — Spatial nodes receives this notification when they are registered to new World resource.
- NOTIFICATION_EXIT_WORLD = 42 — Spatial nodes receives this notification when they are unregistered from current World resource.
- NOTIFICATION_VISIBILITY_CHANGED = 43 — Spatial nodes receives this notification when their visibility changes.
Property Descriptions¶
- SpatialGizmo gizmo
| Setter | set_gizmo(value) |
| Getter | get_gizmo() |
The SpatialGizmo for this node. Used for example in EditorSpatialGizmo as custom visualization and editing handles in Editor.
- Transform global_transform
| Setter | set_global_transform(value) |
| Getter | get_global_transform() |
World space (global) Transform of this node.
- Vector3 rotation
| Setter | set_rotation(value) |
| Getter | get_rotation() |
Rotation part of the local transformation in radians, specified in terms of YXZ-Euler angles in the format (X angle, Y angle, Z angle).
Note: 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.
- Vector3 rotation_degrees
| Default | Vector3( 0, 0, 0 ) |
| Setter | set_rotation_degrees(value) |
| Getter | get_rotation_degrees() |
Rotation part of the local transformation in degrees, specified in terms of YXZ-Euler angles in the format (X angle, Y angle, Z angle).
- Vector3 scale
| Default | Vector3( 1, 1, 1 ) |
| Setter | set_scale(value) |
| Getter | get_scale() |
Scale part of the local transformation.
- Transform transform
| Default | Transform( 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0 ) |
| Setter | set_transform(value) |
| Getter | get_transform() |
Local space Transform of this node, with respect to the parent node.
- Vector3 translation
| Default | Vector3( 0, 0, 0 ) |
| Setter | set_translation(value) |
| Getter | get_translation() |
Local translation of this node.
- bool visible
| Default | true |
| Setter | set_visible(value) |
| Getter | is_visible() |
If true, this node is drawn.
Method Descriptions¶
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.
- Spatial get_parent_spatial ( ) const
Returns the parent Spatial, or an empty Object if no parent exists or parent is not of type Spatial.
- World get_world ( ) const
Returns the current World resource this Spatial node is registered to.
Rotates the global (world) transformation around axis, a unit Vector3, by specified angle in radians. The rotation axis is in global coordinate system.
- void global_scale ( Vector3 scale )
Scales the global (world) transformation by the given Vector3 scale factors.
- void global_translate ( Vector3 offset )
Moves the global (world) transformation by Vector3 offset. The offset is in global coordinate system.
Disables rendering of this node. Changes visible to false.
- bool is_local_transform_notification_enabled ( ) const
Returns whether node notifies about its local transformation changes. Spatial will not propagate this by default.
- bool is_scale_disabled ( ) const
Returns whether this node uses a scale of (1, 1, 1) or its local transformation scale.
- bool is_set_as_toplevel ( ) const
Returns whether this node is set as Toplevel, that is whether it ignores its parent nodes transformations.
- bool is_transform_notification_enabled ( ) const
Returns whether the node notifies about its global and local transformation changes. Spatial will not propagate this by default.
- bool is_visible_in_tree ( ) const
Returns whether the node is visible, taking into consideration that its parents visibility.
Rotates itself so that the local -Z axis points towards the target position.
The transform will first be rotated around the given up vector, and then fully aligned to the target by a further rotation around an axis perpendicular to both the target and up vectors.
Operations take place in global space.
Moves the node to the specified position, and then rotates itself to point toward the target as per look_at. Operations take place in global space.
Resets this node’s transformations (like scale, skew and taper) preserving its rotation and translation by performing Gram-Schmidt orthonormalization on this node’s Transform.
Rotates the local transformation around axis, a unit Vector3, by specified angle in radians.
Rotates the local transformation around axis, a unit Vector3, by specified angle in radians. The rotation axis is in object-local coordinate system.
- void rotate_x ( float angle )
Rotates the local transformation around the X axis by angle in radians.
- void rotate_y ( float angle )
Rotates the local transformation around the Y axis by angle in radians.
- void rotate_z ( float angle )
Rotates the local transformation around the Z axis by angle in radians.
- void scale_object_local ( Vector3 scale )
Scales the local transformation by given 3D scale factors in object-local coordinate system.
- void set_as_toplevel ( bool enable )
Makes the node ignore its parents transformations. Node transformations are only in global space.
- void set_disable_scale ( bool disable )
Sets whether the node uses a scale of (1, 1, 1) or its local transformation scale. Changes to the local transformation scale are preserved.
Reset all transformations for this node (sets its Transform to the identity matrix).
- void set_ignore_transform_notification ( bool enabled )
Sets whether the node ignores notification that its transformation (global or local) changed.
- void set_notify_local_transform ( bool enable )
Sets whether the node notifies about its local transformation changes. Spatial will not propagate this by default.
- void set_notify_transform ( bool enable )
Sets whether the node notifies about its global and local transformation changes. Spatial will not propagate this by default.
Enables rendering of this node. Changes visible to true.
Transforms local_point from this node’s local space to world space.
Transforms global_point from world space to this node’s local space.
- void translate ( Vector3 offset )
Changes the node’s position by the given offset Vector3.
Note that the translation offset is affected by the node’s scale, so if scaled by e.g. (10, 1, 1), a translation by an offset of (2, 0, 0) would actually add 20 (2 * 10) to the X coordinate.
- void translate_object_local ( Vector3 offset )
Changes the node’s position by the given offset Vector3 in local space.
Updates the SpatialGizmo of this node.
