Syntax

public struct SelectableKnot : ISelectableElement, IEquatable<ISelectableElement>, IEquatable<SelectableKnot>

Constructors

SelectableKnot(SplineInfo, Int32)

Creates a SelectableKnot from a SplineInfo and a knot index.

Declaration

public SelectableKnot(SplineInfo info, int index)

Parameters

Type	Name	Description
SplineInfo	info	The SplineInfo associated with the tangent.
Int32	index	The index of the knot.

Properties

KnotIndex

The index of the knot in the spline. If the spline element is a tangent, this is the index of the knot that the tangent is attached to.

Declaration

public readonly int KnotIndex { get; }

Property Value

Type	Description
Int32

Implements

ISelectableElement.KnotIndex

LocalPosition

The position of the spline element in local space.

Declaration

public float3 LocalPosition { get; set; }

Property Value

Type	Description
float3

Implements

ISelectableElement.LocalPosition

LocalRotation

The rotation of the spline element in local space.

Declaration

public quaternion LocalRotation { get; set; }

Property Value

Type	Description
quaternion

Mode

The TangentMode associated with a knot.

Declaration

public TangentMode Mode { get; set; }

Property Value

Type	Description
TangentMode

Position

The position of the spline element in world space.

Declaration

public float3 Position { get; set; }

Property Value

Type	Description
float3

Implements

ISelectableElement.Position

Rotation

The rotation of the spline element in world space.

Declaration

public quaternion Rotation { get; set; }

Property Value

Type	Description
quaternion

SplineInfo

The SplineInfo that describes the spline.

Declaration

public readonly SplineInfo SplineInfo { get; }

Property Value

Type	Description
SplineInfo

Implements

ISelectableElement.SplineInfo

TangentIn

The In tangent associated with the knot. The In tangent defines the curvature of the segment that enters the knot.

Declaration

public readonly SelectableTangent TangentIn { get; }

Property Value

Type	Description
SelectableTangent

TangentOut

The Out tangent associated with the knot. The Out tangent defines the curvature of the segment that exits the knot.

Declaration

public readonly SelectableTangent TangentOut { get; }

Property Value

Type	Description
SelectableTangent

Tension

The tension associated with a knot. Tension is only used if the tangent mode is Auto Smooth.

Declaration

public float Tension { get; set; }

Property Value

Type	Description
Single

Methods

Equals(Object)

Checks if two instances of an object are equal.

Declaration

public override bool Equals(object obj)

Parameters

Type	Name	Description
Object	obj	The object to compare against.

Returns

Type	Description
Boolean	Returns true if obj is a SelectableKnot and its values are identical to the original instance.

Overrides

ValueType.Equals(Object)

Equals(ISelectableElement)

Checks if two instances of SplineElement are equal.

Declaration

public bool Equals(ISelectableElement other)

Parameters

Type	Name	Description
ISelectableElement	other	The ISelectableElement to compare against.

Returns

Type	Description
Boolean	Returns true when other is a SelectableKnot and the values of each instance are identical.

Implements

IEquatable<T>.Equals(T)

Equals(SelectableKnot)

Checks if two instances of SelectableKnot are equal.

Declaration

public bool Equals(SelectableKnot other)

Parameters

Type	Name	Description
SelectableKnot	other	The SelectableKnot to compare against.

Returns

Type	Description
Boolean	Returns true if the values of each instance of SelectableKnot are identical.

Implements

IEquatable<T>.Equals(T)

GetBezierKnot(Boolean)

Creates the BezierKnot representation associated with a SelectableKnot.

Declaration

public BezierKnot GetBezierKnot(bool worldSpace)

Parameters

Type	Name	Description
Boolean	worldSpace	Set to true for the BezierKnot to be in world space, or set to false for the Bezierknot to be in local space.

Returns

Type	Description
BezierKnot	The BezierKnot associated with the knot.

GetHashCode()

Gets a hash code for this knot.

Declaration

public override int GetHashCode()

Returns

Type	Description
Int32	A hash code for the SelectableKnot.

Overrides

ValueType.GetHashCode()

IsValid()

Checks if the element is valid. For example, checks if the spline is not null and the index is valid.

Declaration

public bool IsValid()

Returns

Type	Description
Boolean	Returns true if all fields from the element have valid values.

Implements

ISelectableElement.IsValid()

SetTangentMode(TangentMode, BezierTangent)

Sets the tangent mode of the knot.

Declaration

public void SetTangentMode(TangentMode mode, BezierTangent main)

Parameters

Type	Name	Description
TangentMode	mode	The TangentMode to apply to the knot.
BezierTangent	main	The tangent to use as the main tangent when the tangent is set to the Mirrored or Continuous tangent mode. The main tangent is not modified, but the other tangent attached to that knot is modified to adopt the new tangent mode.
