Most basic 3D game object, parent of all 3D-related nodes.
描述¶
Most basic 3D game object, with a Transform3D and visibility settings. All other 3D game objects inherit from Node3D. Use Node3D 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 Node3D object is set as top-level. Affine operations in this coordinate system correspond to direct affine operations on the Node3D's transform. The word local below refers to this coordinate system. The coordinate system that is attached to the Node3D 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 @GlobalScope.deg_to_rad.
Note: Be aware that "Spatial" nodes are now called "Node3D" starting with Godot 4. Any Godot 3.x references to "Spatial" nodes refer to "Node3D" in Godot 4.

Methods¶
信号¶
visibility_changed ( )
Emitted when node visibility changes.
Enumerations¶
enum RotationEditMode:
RotationEditMode ROTATION_EDIT_MODE_EULER = 0
The rotation is edited using Vector3 Euler angles.
RotationEditMode ROTATION_EDIT_MODE_QUATERNION = 1
The rotation is edited using a Quaternion.
RotationEditMode ROTATION_EDIT_MODE_BASIS = 2
The rotation is edited using a Basis. In this mode, scale can't be edited separately.
常量¶
NOTIFICATION_TRANSFORM_CHANGED = 2000
Node3D 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. The notification is also sent if the node is in the editor context and it has at least one valid gizmo.
NOTIFICATION_ENTER_WORLD = 41
Node3D nodes receives this notification when they are registered to new World3D resource.
NOTIFICATION_EXIT_WORLD = 42
Node3D nodes receives this notification when they are unregistered from current World3D resource.
NOTIFICATION_VISIBILITY_CHANGED = 43
Node3D nodes receives this notification when their visibility changes.
NOTIFICATION_LOCAL_TRANSFORM_CHANGED = 44
Node3D nodes receives this notification when their local transform changes. This is not received when the transform of a parent node is changed.
In order for NOTIFICATION_LOCAL_TRANSFORM_CHANGED to work, users first need to ask for it, with set_notify_local_transform.
Property Descriptions¶
Basis basis
Direct access to the 3x3 basis of the transform property.
Basis global_basis
Global basis of this node. This is equivalent to global_transform.basis.
Vector3 global_position
Global position of this node. This is equivalent to global_transform.origin.
Vector3 global_rotation
Rotation part of the global 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 global_rotation_degrees
Helper property to access global_rotation in degrees instead of radians.
Transform3D global_transform
void set_global_transform ( Transform3D value )
Transform3D get_global_transform ( )
World3D space (global) Transform3D of this node.
Vector3 position = Vector3(0, 0, 0)
Local position or translation of this node relative to the parent. This is equivalent to transform.origin.
Quaternion quaternion
void set_quaternion ( Quaternion value )
Quaternion get_quaternion ( )
Access to the node rotation as a Quaternion. This property is ideal for tweening complex rotations.
Vector3 rotation = Vector3(0, 0, 0)
Rotation part of the local transformation in radians, specified in terms of Euler angles. The angles construct a rotation in the order specified by the rotation_order property.
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.
Note: This property is edited in the inspector in degrees. If you want to use degrees in a script, use rotation_degrees.
Vector3 rotation_degrees
Helper property to access rotation in degrees instead of radians.
RotationEditMode rotation_edit_mode = 0
void set_rotation_edit_mode ( RotationEditMode value )
RotationEditMode get_rotation_edit_mode ( )
Specify how rotation (and scale) will be presented in the editor.
EulerOrder rotation_order = 2
void set_rotation_order ( EulerOrder value )
EulerOrder get_rotation_order ( )
Specify the axis rotation order of the rotation property. The final orientation is constructed by rotating the Euler angles in the order specified by this property.
Vector3 scale = Vector3(1, 1, 1)
Scale part of the local transformation.
Note: 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.
Note: Not all nodes are visually scaled by the scale property. For example, Light3Ds are not visually affected by scale.
bool top_level = false
If true, the node will not inherit its transformations from its parent. Node transformations are only in global space.
Transform3D transform = Transform3D(1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0)
void set_transform ( Transform3D value )
Transform3D get_transform ( )
Local space Transform3D of this node, with respect to the parent node.
NodePath visibility_parent = NodePath("")
Defines the visibility range parent for this node and its subtree. The visibility parent must be a GeometryInstance3D. Any visual instance will only be visible if the visibility parent (and all of its visibility ancestors) is hidden by being closer to the camera than its own GeometryInstance3D.visibility_range_begin. Nodes hidden via the visible property are essentially removed from the visibility dependency tree, so dependent instances will not take the hidden node or its ancestors into account.
bool visible = true
If true, this node is drawn. The node is only visible if all of its ancestors are visible as well (in other words, is_visible_in_tree must return true).
Method Descriptions¶
void add_gizmo ( Node3DGizmo gizmo )
Attach a gizmo to this Node3D.
void clear_gizmos ( )
Clear all gizmos attached to this Node3D.
void clear_subgizmo_selection ( )
Clears subgizmo selection for this node in the editor. Useful when subgizmo IDs become invalid after a property change.
void force_update_transform ( )
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.
Node3DGizmo[] get_gizmos ( ) const
Returns all the gizmos attached to this Node3D.
Node3D get_parent_node_3d ( ) const
Returns the parent Node3D, or an empty Object if no parent exists or parent is not of type Node3D.
World3D get_world_3d ( ) const
Returns the current World3D resource this Node3D node is registered to.
void global_rotate ( Vector3 axis, float angle )
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.
void hide ( )
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. Node3D 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_transform_notification_enabled ( ) const
Returns whether the node notifies about its global and local transformation changes. Node3D will not propagate this by default.
bool is_visible_in_tree ( ) const
Returns true if the node is present in the SceneTree, its visible property is true and all its ancestors are also visible. If any ancestor is hidden, this node will not be visible in the scene tree.
void look_at ( Vector3 target, Vector3 up=Vector3(0, 1, 0), bool use_model_front=false )
Rotates the node so that the local forward axis (-Z, Vector3.FORWARD) points toward the target position.
The local up axis (+Y) points as close to the up 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 target position cannot be the same as the node's position, the up vector cannot be zero, and the direction from the node's position to the target vector cannot be parallel to the up vector.
Operations take place in global space, which means that the node must be in the scene tree.
If use_model_front is true, the +Z axis (asset front) is treated as forward (implies +X is left) and points toward the target position. By default, the -Z axis (camera forward) is treated as forward (implies +X is right).
void look_at_from_position ( Vector3 position, Vector3 target, Vector3 up=Vector3(0, 1, 0), bool use_model_front=false )
Moves the node to the specified position, and then rotates the node to point toward the target as per look_at. Operations take place in global space.
void orthonormalize ( )
Resets this node's transformations (like scale, skew and taper) preserving its rotation and translation by performing Gram-Schmidt orthonormalization on this node's Transform3D.
void rotate ( Vector3 axis, float angle )
Rotates the local transformation around axis, a unit Vector3, by specified angle in radians.
void rotate_object_local ( Vector3 axis, float angle )
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_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.
void set_identity ( )
Reset all transformations for this node (sets its Transform3D 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. Node3D will not propagate this by default.
void set_notify_transform ( bool enable )
Sets whether the node notifies about its global and local transformation changes. Node3D will not propagate this by default, unless it is in the editor context and it has a valid gizmo.
void set_subgizmo_selection ( Node3DGizmo gizmo, int id, Transform3D transform )
Set subgizmo selection for this node in the editor.
void show ( )
Enables rendering of this node. Changes visible to true.
Vector3 to_global ( Vector3 local_point ) const
Transforms local_point from this node's local space to world space.
Vector3 to_local ( Vector3 global_point ) const
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.
void update_gizmos ( )
Updates all the Node3DGizmos attached to this node.
