Ring

Sealed shape drawer that renders ring (circle outline) shapes using the Shapes library. Contains the nested Ring readonly struct for storing ring parameters. Unlike PieDrawer, the normal is stored as-is without negation.

Definition

Namespace: Paragon.Core.ShapesDrawer Assembly: Paragon.dll

public sealed class RingDrawer : ShapeDrawer<RingDrawer.Ring>

Inheritance: ShapeDrawer<Ring> → RingDrawer

Methods

Add

Enqueues a ring for rendering this frame.

public void Add(Vector3 center, Vector3 normal, float radius, Color color, float thickness = 1f)

Parameter	Type	Default	Description
center	Vector3	—	Ring center position
normal	Vector3	—	Normal direction of the ring plane
radius	float	—	Ring radius
color	Color	—	Ring color
thickness	float	1f	Ring stroke thickness in pixels

Draw

Renders all queued rings. Sets lineGeometry and thicknessSpace from the base class, then iterates the queue calling Shapes.Draw.Ring() with DiscColors.Flat() for each entry.

public override void Draw()

Ring Struct

Readonly struct holding all parameters for a single ring draw call.

public readonly struct Ring
{
    public readonly Vector3 Center;
    public readonly Vector3 Normal;
    public readonly float Radius;
    public readonly Color Color;
    public readonly float Thickness;
}

Common Pitfalls

Normal is NOT negated. Unlike PieDrawer and ArcDrawer, the Ring constructor stores the normal as-is. If you're switching between ring and pie/arc drawing, be aware of this difference.

Examples

Direct Usage via ShapesDrawer

// Draw a ring on the XZ plane
ShapesDrawer.DrawRing(
    transform.position,
    Vector3.up,
    radius: 5f,
    Color.green,
    thickness: 2f
);

Range Indicator

public override void OnDebug()
{
    // Inner and outer range rings
    ShapesDrawer.DrawRing(transform.position, Vector3.up, minRange, Color.yellow);
    ShapesDrawer.DrawRing(transform.position, Vector3.up, maxRange, Color.red, thickness: 2f);
}
