Draw Debug Circle (Matrix)

Plugin: StateTreeToolsCore Category: Debug

Draws a debug circle oriented by a full transformation matrix. When While Task Is Active is enabled the circle is redrawn every tick. When disabled it is drawn once on enter and the task immediately succeeds. For a simpler center+axis-vector version see Draw Debug Circle.


Configuration

Transform Matrix

The FMatrix that positions and orients the circle in world space.

Radius

The radius of the circle in world units. Default is 100.

Segments

The number of line segments used to approximate the circle. Default is 12.

Color

The color of the circle. Default is red.

Draw Axis

When enabled the matrix axes are drawn as lines through the center. Default is true.

While Task Is Active

When enabled the circle is redrawn every tick and the task stays running until the state exits. When disabled it is drawn once on enter.

Persistent Lines

When enabled (and While Task Is Active is off) the circle persists until FlushPersistentDebugLines is called.

Life Time

How long the circle remains visible in seconds. A value of -1 uses the engine default. Only active when While Task Is Active and Persistent Lines are both off.

Depth Priority

Rendering depth priority. Default is 0.

Thickness

Line thickness in world units. Default is 0 (hairline).
