<brief_description>
|
|
A class used by the editor to define Node3D gizmo types.
|
|
</brief_description>
|
|
<description>
|
|
[EditorNode3DGizmoPlugin] allows you to define a new type of Gizmo. There are two main ways to do so: extending [EditorNode3DGizmoPlugin] for the simpler gizmos, or creating a new [EditorNode3DGizmo] type. See the tutorial in the documentation for more info.
|
|
To use [EditorNode3DGizmoPlugin], register it using the [method EditorPlugin.add_node_3d_gizmo_plugin] method first.

<description>
|
|
Override this method to commit a handle being edited (handles must have been previously added by [method EditorNode3DGizmo.add_handles] during [method _redraw]). This usually means creating an [UndoRedo] action for the change, using the current handle value as "do" and the [param restore] argument as "undo".
|
|
If the [param cancel] argument is [code]true[/code], the [param restore] value should be directly set, without any [UndoRedo] action.
|
|
The [param secondary] argument is [code]true[/code] when the committed handle is secondary (see [method EditorNode3DGizmo.add_handles] for more information).
|
|
Called for this plugin's active gizmos.

<description>
|
|
Override this method to commit a group of subgizmos being edited (see [method _subgizmos_intersect_ray] and [method _subgizmos_intersect_frustum]). This usually means creating an [UndoRedo] action for the change, using the current transforms as "do" and the [param restores] transforms as "undo".
|
|
If the [param cancel] argument is [code]true[/code], the [param 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.

<description>
|
|
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 [code]restore[/code] argument in [method _commit_handle].
|
|
The [param secondary] argument is [code]true[/code] when the requested handle is secondary (see [method EditorNode3DGizmo.add_handles] for more information).

<return type="int" />
|
|
<description>
|
|
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 [code]-1[/code]. If not overridden, this method will return [code]0[/code], which means custom gizmos will automatically get higher priority than built-in gizmos.

<description>
|
|
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.

|
<description>
|
|
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 [code]true[/code] the node gets a generic [EditorNode3DGizmo] assigned and is added to this plugin's list of active gizmos.

<description>
|
|
Override this method to update the node's properties when the user drags a gizmo handle (previously added with [method EditorNode3DGizmo.add_handles]). The provided [param screen_pos] is the mouse position in screen coordinates and the [param camera] can be used to convert it to raycasts.

Override this method to allow selecting subgizmos using mouse drag box selection. Given a [param camera] and [param frustum_planes], this method should return which subgizmos are contained within the frustums. The [param frustum_planes] argument consists of an array with all the [Plane]s 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 [method _get_subgizmo_transform] or [method _commit_subgizmos].
