Class EditorNode3DGizmo

Gizmo for editing Node3D objects.

Inheritance
EditorNode3DGizmo

Remarks

Gizmo that is used for providing custom visualization and editing (handles and subgizmos) for Node3D objects. Can be overridden to create custom gizmos, but for simple gizmos creating a EditorNode3DGizmoPlugin is usually recommended.

Methods

_begin_handle_action(int, bool)

Qualifiers: virtual

void _begin_handle_action(int id, bool secondary)

Parameters

id int
secondary bool

_commit_handle(int, bool, Variant, bool)

Qualifiers: virtual

Override this method to commit a handle being edited (handles must have been previously added by EditorNode3DGizmo.add_handles). This usually means creating an UndoRedo action for the change, using the current handle value as "do" and the restore argument as "undo".

If the cancel argument is true, the restore value should be directly set, without any UndoRedo action.

The secondary argument is true when the committed handle is secondary (see EditorNode3DGizmo.add_handles for more information).

void _commit_handle(int id, bool secondary, Variant restore, bool cancel)

Parameters

id int
secondary bool
restore Variant
cancel bool

_commit_subgizmos(PackedInt32Array, Transform3D[], bool)

Qualifiers: virtual

Override this method to commit a group of subgizmos being edited (see EditorNode3DGizmo._subgizmos_intersect_ray and EditorNode3DGizmo._subgizmos_intersect_frustum). This usually means creating an UndoRedo action for the change, using the current transforms as "do" and the restores transforms as "undo".

If the cancel argument is true, the restores transforms should be directly set, without any UndoRedo action.

void _commit_subgizmos(PackedInt32Array ids, Transform3D[] restores, bool cancel)

Parameters

ids PackedInt32Array
restores Transform3D[]
cancel bool

_get_handle_name(int, bool)

Qualifiers: virtualconst

Override this method to return the name of an edited handle (handles must have been previously added by EditorNode3DGizmo.add_handles). Handles can be named for reference to the user when editing.

The secondary argument is true when the requested handle is secondary (see EditorNode3DGizmo.add_handles for more information).

String _get_handle_name(int id, bool secondary)

Parameters

id int
secondary bool

_get_handle_value(int, bool)

Qualifiers: virtualconst

Override this method to return the current value of a handle. This value will be requested at the start of an edit and used as the restore argument in EditorNode3DGizmo._commit_handle.

The secondary argument is true when the requested handle is secondary (see EditorNode3DGizmo.add_handles for more information).

Variant _get_handle_value(int id, bool secondary)

Parameters

id int
secondary bool

_get_subgizmo_transform(int)

Qualifiers: virtualconst

Override this method to return the current transform of a subgizmo. This transform will be requested at the start of an edit and used as the restore argument in EditorNode3DGizmo._commit_subgizmos.

Transform3D _get_subgizmo_transform(int id)

Parameters

id int

_is_handle_highlighted(int, bool)

Qualifiers: virtualconst

Override this method to return true whenever the given handle should be highlighted in the editor.

The secondary argument is true when the requested handle is secondary (see EditorNode3DGizmo.add_handles for more information).

bool _is_handle_highlighted(int id, bool secondary)

Parameters

id int
secondary bool

_redraw

Qualifiers: virtual

Override this method to add all the gizmo elements whenever a gizmo update is requested. It's common to call clear at the beginning of this method and then add visual elements depending on the node's properties.

void _redraw

_set_handle(int, bool, Camera3D, Vector2)

Qualifiers: virtual

Override this method to update the node properties when the user drags a gizmo handle (previously added with EditorNode3DGizmo.add_handles). The provided point is the mouse position in screen coordinates and the camera can be used to convert it to raycasts.

The secondary argument is true when the edited handle is secondary (see EditorNode3DGizmo.add_handles for more information).

void _set_handle(int id, bool secondary, Camera3D camera, Vector2 point)

Parameters

id int
secondary bool
camera Camera3D
point Vector2

_set_subgizmo_transform(int, Transform3D)

Qualifiers: virtual

Override this method to update the node properties during subgizmo editing (see EditorNode3DGizmo._subgizmos_intersect_ray and EditorNode3DGizmo._subgizmos_intersect_frustum). The transform is given in the Node3D's local coordinate system.

void _set_subgizmo_transform(int id, Transform3D transform)

Parameters

id int
transform Transform3D

_subgizmos_intersect_frustum(Camera3D, Plane[])

Qualifiers: virtualconst

Override this method to allow selecting subgizmos using mouse drag box selection. Given a camera and a frustum, this method should return which subgizmos are contained within the frustum. The frustum argument consists of an array with all the Planes that make up the selection frustum. The returned value should contain a list of unique subgizmo identifiers, which can have any non-negative value and will be used in other virtual methods like EditorNode3DGizmo._get_subgizmo_transform or EditorNode3DGizmo._commit_subgizmos.

PackedInt32Array _subgizmos_intersect_frustum(Camera3D camera, Plane[] frustum)

Parameters

camera Camera3D
frustum Plane[]

_subgizmos_intersect_ray(Camera3D, Vector2)

Qualifiers: virtualconst

Override this method to allow selecting subgizmos using mouse clicks. Given a camera and a point in screen coordinates, this method should return which subgizmo should be selected. The returned value should be a unique subgizmo identifier, which can have any non-negative value and will be used in other virtual methods like EditorNode3DGizmo._get_subgizmo_transform or EditorNode3DGizmo._commit_subgizmos.

int _subgizmos_intersect_ray(Camera3D camera, Vector2 point)

Parameters

camera Camera3D
point Vector2

add_collision_segments(PackedVector3Array)

Adds the specified segments to the gizmo's collision shape for picking. Call this method during _redraw.

void add_collision_segments(PackedVector3Array segments)

Parameters

segments PackedVector3Array

add_collision_triangles(TriangleMesh)

Adds collision triangles to the gizmo for picking. A TriangleMesh can be generated from a regular Mesh too. Call this method during _redraw.

void add_collision_triangles(TriangleMesh triangles)

Parameters

triangles TriangleMesh

add_handles(PackedVector3Array, Material, PackedInt32Array, bool, bool)

Adds a list of handles (points) which can be used to edit the properties of the gizmo's Node3D. The ids argument can be used to specify a custom identifier for each handle, if an empty array is passed, the ids will be assigned automatically from the handles argument order.

The secondary argument marks the added handles as secondary, meaning they will normally have lower selection priority than regular handles. When the user is holding the shift key secondary handles will switch to have higher priority than regular handles. This change in priority can be used to place multiple handles at the same point while still giving the user control on their selection.

There are virtual methods which will be called upon editing of these handles. Call this method during _redraw.

void add_handles(PackedVector3Array handles, Material material, PackedInt32Array ids, bool billboard, bool secondary)

Parameters

handles PackedVector3Array
material Material
ids PackedInt32Array
billboard bool
secondary bool

add_lines(PackedVector3Array, Material, bool, Color)

Adds lines to the gizmo (as sets of 2 points), with a given material. The lines are used for visualizing the gizmo. Call this method during _redraw.

void add_lines(PackedVector3Array lines, Material material, bool billboard, Color modulate)

Parameters

lines PackedVector3Array
material Material
billboard bool
modulate Color

add_mesh(Mesh, Material, Transform3D, SkinReference)

Adds a mesh to the gizmo with the specified material, local transform and skeleton. Call this method during _redraw.

void add_mesh(Mesh mesh, Material material, Transform3D transform, SkinReference skeleton)

Parameters

mesh Mesh
material Material
transform Transform3D
skeleton SkinReference

add_unscaled_billboard(Material, float, Color)
