Class ScyllaQuadShape

Parametric vertical quad in the XY plane (facing +Z), with configurable width and height. Equivalent to Unity's built-in quad primitive but with serialized dimensions that can be retuned in the Inspector or at runtime.

Syntax
[AddComponentMenu("Scylla/Geometry/Quad")]
public sealed class ScyllaQuadShape : ScyllaShapeBase3D
Remarks

The mesh is a single 4-vertex / 2-triangle quad. Normals point along +Z. UVs span (0,0) at the bottom-left to (1,1) at the top-right. The quad is centered at local origin.

Because the quad has only one face, it is typically used with DoubleSided set to true so it is visible from both sides. Per-face coloring is supported: face index 0 of 1 is passed to the resolver, which assigns one solid color to all four vertices.

The MatchingPrimitive option is not overridden for this shape; it falls back to UnityEngine.MeshCollider. For a paper-thin collider matching a flat quad, consider using ScyllaPlaneShape (which attaches a thin UnityEngine.BoxCollider) or assigning a collider manually.

Properties

Height

Quad size along the Y axis. Values below 0.0001 are clamped when set and at build time. Setting this triggers an immediate mesh rebuild and updates Size.

Declaration
public float Height { get; set; }
Property Value
Type Description
float

Size

Quad extent on the XY plane as a Size2D. Width maps to X, Height maps to Y. Components below 0.0001 are clamped when set and at build time. Setting this triggers an immediate rebuild.

Declaration
public Size2D Size { get; set; }
Property Value
Type Description
Size2D

Width

Quad size along the X axis. Values below 0.0001 are clamped when set and at build time. Setting this triggers an immediate mesh rebuild and updates Size.

Declaration
public float Width { get; set; }
Property Value
Type Description
float

Methods

Build(Mesh, float, float, IFaceColorResolver)

Populates target with a single-quad mesh in the XY plane facing +Z. Existing mesh data is overwritten.

Declaration
public static void Build(Mesh target, float width, float height, IFaceColorResolver resolver = null)
Parameters
Type Name Description
Mesh target

Destination mesh. Must be non-null.
float width

Quad width along the X axis. Clamped to a minimum of 0.0001.
float height

Quad height along the Y axis. Clamped to a minimum of 0.0001.
IFaceColorResolver resolver

Optional per-face color resolver. When non-null, a per-vertex color channel is emitted with the single face's color (face index 0 of 1). When null, no color channel is written.

BuildMesh(Mesh)

Subclass extension point: write vertex / triangle / normal / uv data into target from the shape's serialized parameters. The base class calls Clear(bool) before invoking this method and UnityEngine.Mesh.RecalculateBounds() afterwards, so subclasses should not invoke either themselves.

Declaration
protected override void BuildMesh(Mesh target)
Parameters
Type Name Description
Mesh target

The owned mesh to populate. Already cleared by the base class.
Overrides

GetMeshName()

Returns the shape's mesh name as it should appear on the generated mesh asset. Defaults to the subclass type name; override to provide a friendlier label.

Declaration
protected override string GetMeshName()
Returns
Type Description
string

A short identifier for the generated mesh, used as UnityEngine.Object.name.
Overrides
