DrawGizmoAttribute

Remarks

Doc 36 § D3, and Unity's [DrawGizmo]. The method is what Draw takes.

[DrawGizmo(typeof(SpawnPoint), SelectedOnly = true)] public static void Draw(GizmoDraw draw, object component, GizmoPlacement placement, bool selected) { draw.Sphere(placement.Position, ((SpawnPoint) component).Radius, new(0.2f, 0.9f, 0.4f, 1f)); }

⚠ The component is Object rather than the target type, and casting it is the author's line. A typed delegate would need the attribute to be generic, which an attribute cannot be over a type argument the scanner discovers at run time. The cast is checked — the drawer is only ever called for an entity carrying Target.

⚠ Read by a scan of the assembly that declared it, and only for a plugin or a project script — see CustomInspectorAttribute for why that is bounded rather than the assembly scanning ADR-002 refuses. In-tree code registers a ComponentGizmo directly.
