Class TCastleLine2DBase

Unit

CastleLine2DBase

Declaration

type TCastleLine2DBase = class(TCastleAbstractPrimitive)

Description

Base class for shapes that are defined by a set of vertices Points. Inherited classes should override the ReLoad method.) A property editor is provided for the Points vertex set It is also possible to edit a set of vertices from the CGE editor window. To enter edit mode, use "verb" (Edit mode ON) - right-click on the object in the object hierarchy window.
