class Property

Defined in: C4Properties.h

Every property that can be attached to a scene graph node is a subclass of the Property class.

Definition

class Property : public MapElement<Property>, public Packable, public Configurable, public Registrable<Property, PropertyRegistration>

Member Functions

`Property::GetPropertyType`	Returns the property type.
`Property::GetPropertyFlags`	Returns the property flags.
`Property::SetPropertyFlags`	Returns the property flags.
`Property::ValidNode`	Returns a boolean value indicating whether the property can be assigned to a particular node.

Constructor

Property(PropertyType type);

Parameters

type The property type.

Description

The Property class is a generic container for any kind of special information that can be attached to a scene graph node. An application may define its own custom properties, and they become visible in the World Editor.

A custom property type is usually defined by creating a subclass of the Property class. For the property type to be visible in the World Editor, it is also necessary to construct an associated PropertyReg object. Although a subclass is normally created for custom property types, using the base class alone is allowed if the property does not need to carry any information beyond its type. (It may be sufficient for the application to simply detect that a particular type of property exists for a node.) In this case, the custom property type still needs to be registered using the PropertyReg template, but the classType template parameter may simply be Property.

A custom property can expose its data to the World Editor by implementing the functions of the Configurable base class.

Base Classes

`MapElement<Property>`	Properties are stored in a map.
`Packable`	Properties can be packed for storage in resources.
`Configurable`	Properties can define configurable parameters that are exposed as user interface widgets in the World Editor.
`Registrable<Property, PropertyRegistration>`	Custom property types can be registered with the engine.
