Blueprint Spline Component Property Reference in Unreal Engine | Unreal Engine 5.5 Documentation

This page contains a reference listing of properties available on Blueprint Spline Components. The properties displayed will be slightly different if the Blueprint Spline Component is selected in the Blueprint Editor, is a Root Component, or if the component is selected in the Level Editor.

Properties

Transform

Property	Description
Location	The location of the Actor or Component in World Space or Relative to its parent.
Rotation	The rotation of the Actor or Component in World Space or Relative to its parent.
Scale	The Scale of the Actor or Component in World Space or Relative to its parent.

Sockets

Property	Description
Parent Socket	When this component is the Child of a Skeletal Mesh Component (or Static Mesh Component with a Socket), you can specify a Socket or Joint to attach this component to.

Spline

Property	Description
Duration	%doxygen:USplineComponent::Duration%
Override Construction Script	%doxygen:USplineComponent::bSplineHasBeenEdited%
Input Spline Points to Construction Script	%doxygen:USplineComponent::bInputSplinePointsToConstructionScript%
Draw Debug	%doxygen:USplineComponent::bDrawDebug%
Closed Loop	%doxygen:USplineComponent::bClosedLoop%
Default Up Vector	%doxygen:USplineComponent::DefaultUpVector%

Advanced

Property	Description
Reparam Steps Per Segment	%doxygen:USplineComponent::ReparamStepsPerSegment%
Stationary Endpoints	%doxygen:USplineComponent::bStationaryEndpoints%

Editor

Property	Description
Editor Unselected Spline Segment Color	Color of an unselected spline component segment in the editor.
Editor Selected Spline Segment Color	Color of a selected spline component segment in the editor.
Should Visualize Scale	Whether or not scale visualization should be displayed in the editor.
Scale Visualization Width	Width of the spline when scale visualization is enabled in the editor.

Selected Points

Property	Description
Input Key	This is the index of the selected Curve Point on the curve.
Position	This is the location of the selected Curve Point in local space.
Arrive Tangent	This is the vector that defines the tangent of the curve as it approaches the selected Curve Point.
Leave Tangent	This is the vector that defines the tangent of the curve as it departs the selected Curve Point.
Rotation	Rotation can be applied to a Curve Point to modify its tangents. This value is applied separately from the tangents, so both can be modified to create the desired results.
Scale	Scale can be applied to a Curve Point to modify its tangents. This value is applied separately from the tangents, so both can be modified to create the desired results.
Type	Defines the type of curve at the selected Curve Point. Linear: From the selected Curve Point to the next, the curve will be straight. This affects the tangent coming into the selected Curve Point as well as the tanget departing the next. Curve: Default value. The locations of the Curve Points (before and after the selected one) define the tangents of the selected Curve Point. Constant: Like Linear but doesn't affect the tangent coming into the selected Curve Point as well as the tanget departing the next. CurveClamped: Like Curve but it clamps the tangents of the curve. CurveCustomTangent: If you adjust any tangent on a Curve Point, it is set to this value.
