EditorNode3DGizmoPlugin #

virtual func _begin_handle_action(secondary: bool) -> void#

virtual const func _can_be_hidden() -> bool#

Override this method to define whether the gizmos handled by this plugin can be hidden or not. Returns true if not overridden.

virtual func _commit_handle(cancel: bool) -> void#

Override this method to commit a handle being edited (handles must have been previously added by EditorNode3DGizmo.add_handles during _redraw). 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).

Called for this plugin's active gizmos.

virtual func _commit_subgizmos(cancel: bool) -> void#

Override this method to commit a group of subgizmos being edited (see _subgizmos_intersect_ray and _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. As with all subgizmo methods, transforms are given in local space respect to the gizmo's Node3D. Called for this plugin's active gizmos.

virtual const func _create_gizmo(for_node_3d: Node3D) -> EditorNode3DGizmo#

Override this method to return a custom EditorNode3DGizmo for the 3D nodes of your choice, return null for the rest of nodes. See also _has_gizmo.

virtual const func _get_gizmo_name() -> String#

Override this method to provide the name that will appear in the gizmo visibility menu.

virtual const func _get_handle_name(secondary: bool) -> String#

Override this method to provide gizmo's handle names. The secondary argument is true when the requested handle is secondary (see EditorNode3DGizmo.add_handles for more information). Called for this plugin's active gizmos.

virtual const func _get_handle_value(secondary: bool) -> Variant#

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 _commit_handle.

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

Called for this plugin's active gizmos.

virtual const func _get_priority() -> int#

Override this method to set the gizmo's priority. Gizmos with higher priority will have precedence when processing inputs like handles or subgizmos selection.

All built-in editor gizmos return a priority of -1. If not overridden, this method will return 0, which means custom gizmos will automatically get higher priority than built-in gizmos.

virtual const func _get_subgizmo_transform(subgizmo_id: int) -> Transform3D#

Override this method to return the current transform of a subgizmo. As with all subgizmo methods, the transform should be in local space respect to the gizmo's Node3D. This transform will be requested at the start of an edit and used in the restore argument in _commit_subgizmos. Called for this plugin's active gizmos.

virtual const func _has_gizmo(for_node_3d: Node3D) -> bool#

Override this method to define which Node3D nodes have a gizmo from this plugin. Whenever a Node3D node is added to a scene this method is called, if it returns true the node gets a generic EditorNode3DGizmo assigned and is added to this plugin's list of active gizmos.

virtual const func _is_handle_highlighted(secondary: bool) -> bool#

Override this method to return true whenever to 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). Called for this plugin's active gizmos.

virtual const func _is_selectable_when_hidden() -> bool#

Override this method to define whether Node3D with this gizmo should be selectable even when the gizmo is hidden.

virtual func _redraw(gizmo: EditorNode3DGizmo) -> void#

Override this method to add all the gizmo elements whenever a gizmo update is requested. It's common to call EditorNode3DGizmo.clear at the beginning of this method and then add visual elements depending on the node's properties.

virtual func _set_handle(screen_pos: Vector2) -> void#

Override this method to update the node's properties when the user drags a gizmo handle (previously added with EditorNode3DGizmo.add_handles). The provided screen_pos 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).

Called for this plugin's active gizmos.

virtual func _set_subgizmo_transform(transform: Transform3D) -> void#

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

virtual const func _subgizmos_intersect_frustum(frustum_planes: Plane[]) -> PackedInt32Array#

Override this method to allow selecting subgizmos using mouse drag box selection. Given a camera and frustum_planes, this method should return which subgizmos are contained within the frustums. The frustum_planes 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, these identifiers can have any non-negative value and will be used in other virtual methods like _get_subgizmo_transform or _commit_subgizmos. Called for this plugin's active gizmos.

virtual const func _subgizmos_intersect_ray(screen_pos: Vector2) -> int#

Override this method to allow selecting subgizmos using mouse clicks. Given a camera and a screen_pos 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 _get_subgizmo_transform or _commit_subgizmos. Called for this plugin's active gizmos.

func add_material(material: StandardMaterial3D) -> void#

Adds a new material to the internal material list for the plugin. It can then be accessed with get_material. Should not be overridden.

func create_handle_material(texture: Texture2D = null) -> void#

Creates a handle material with its variants (selected and/or editable) and adds them to the internal material list. They can then be accessed with get_material and used in EditorNode3DGizmo.add_handles. Should not be overridden.

You can optionally provide a texture to use instead of the default icon.

func create_icon_material(color: Color = Color(1, 1, 1, 1)) -> void#

Creates an icon material with its variants (selected and/or editable) and adds them to the internal material list. They can then be accessed with get_material and used in EditorNode3DGizmo.add_unscaled_billboard. Should not be overridden.

func create_material(use_vertex_color: bool = false) -> void#

Creates an unshaded material with its variants (selected and/or editable) and adds them to the internal material list. They can then be accessed with get_material and used in EditorNode3DGizmo.add_mesh and EditorNode3DGizmo.add_lines. Should not be overridden.

func get_material(gizmo: EditorNode3DGizmo = null) -> StandardMaterial3D#

Gets material from the internal list of materials. If an EditorNode3DGizmo is provided, it will try to get the corresponding variant (selected and/or editable).
