Class SplineDataHandle<T>

SplineDataHandle is a base class to override in order to enable custom handles for spline data. The Drawer needs to inherit from this class and override the method corresponding to the correct splineData type. Either one of the method or both can be overriden regarding the user needs.

Inheritance

Object

SplineDataHandle<T>

Namespace: UnityEditor.Splines

Syntax

public abstract class SplineDataHandle<T> : object, ISplineDataHandle

Type Parameters

Name	Description
T	The type parameter of the SplineData<T> that this drawer targets.

Properties

attribute

Declaration

public SplineDataHandleAttribute attribute { get; }

Property Value

Type	Description
SplineDataHandleAttribute

controlIDs

Array of reserved control IDs used for SplineData<T> handles.

Declaration

public int[] controlIDs { get; }

Property Value

Type	Description
Int32[]

Methods

DrawDataPoint(Int32, Vector3, Vector3, Vector3, SplineData<T>, Int32)

Override this method to create custom handles for a DataPoint<TDataType>in SplineData<T>, 'position' and 'direction' are given in the Spline-space basis. This method is called after DrawSplineData in the render loop.

Declaration

public virtual void DrawDataPoint(int controlID, Vector3 position, Vector3 direction, Vector3 upDirection, SplineData<T> splineData, int dataPointIndex)

Parameters

Type	Name	Description
Int32	controlID	A control ID from controlIDs that represents this handle.
Vector3	position	The position of the keyframe data in spline space.
Vector3	direction	The direction of the spline at the current keyframe.
Vector3	upDirection	The up vector orthogonal to the spline direction at the current keyframe regarding knot rotation.
SplineData<T>	splineData	The SplineData<T> for which the method is drawing handles.
Int32	dataPointIndex	The index of the current keyframe to handle.

DrawSplineData(SplineData<T>, Spline, Matrix4x4, Color)

Override this method to create custom handles for SplineData<T>, this method is called before DrawKeyframe in the render loop.

Declaration

public virtual void DrawSplineData(SplineData<T> splineData, Spline spline, Matrix4x4 localToWorld, Color color)

Parameters

Type	Name	Description
SplineData<T>	splineData	The SplineData<T> for which the method is drawing handles.
Spline	spline	The target Spline associated to the SplineData for the drawing.
Matrix4x4	localToWorld	The spline localToWorld Matrix.
Color	color	The color defined in the SplineData scene interface.
