Line

Sealed shape drawer that renders lines using the Shapes library. Contains the nested Line readonly struct for storing line parameters and the LineEndCap enum. The simplest and most commonly used drawer in the system.

Definition

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

public sealed class LineDrawer : ShapeDrawer<LineDrawer.Line>

Inheritance: ShapeDrawer<Line> → LineDrawer

Methods

Add

Enqueues a line for rendering this frame.

public void Add(Vector3 start, Vector3 end, Color color, float thickness = 1f, LineEndCap lineEndCap = LineEndCap.NONE)

Parameter	Type	Default	Description
start	Vector3	—	Line start position
end	Vector3	—	Line end position
color	Color	—	Line color
thickness	float	1f	Thickness in pixels
lineEndCap	LineEndCap	NONE	End cap style

Draw

Renders all queued lines. Applies lineGeometry and thicknessSpace, then iterates the queue calling Shapes.Draw.Line() for each entry.

public override void Draw()

Line Struct

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

public readonly struct Line
{
    public readonly Vector3 Start;
    public readonly Vector3 End;
    public readonly Color Color;
    public readonly float Thickness;
    public readonly LineEndCap LineEndCap;
}

LineEndCap Enum

Paragon wrapper around the Shapes library's LineEndCap enum.

public enum LineEndCap
{
    NONE   = Shapes.LineEndCap.None,
    SQUARE = Shapes.LineEndCap.Square,
    ROUND  = Shapes.LineEndCap.Round
}

Examples

Direct Usage via ShapesDrawer

// Simple line
ShapesDrawer.DrawLine(Vector3.zero, Vector3.forward * 5f, Color.red);

// Thick line with round caps
ShapesDrawer.DrawLine(start, end, Color.green, thickness: 3f, lineEndCap: LineEndCap.ROUND);

Debug Visualization

public override void OnDebug()
{
    // Draw velocity vector
    ShapesDrawer.DrawLine(
        transform.position,
        transform.position + velocity,
        Color.cyan,
        thickness: 2f,
        lineEndCap: LineEndCap.ROUND
    );
}
