Description

This is the base class for all scene objects such as RIAvatar, RIProp, RICamera, etc. Deployed objects might come across some points of operation failure during the course of one's work with the scene, i.e. deletion, undo/redo operations, file importation, etc. Therefore, RIBase provides IsValid to detect for scene objects' validity.

Inheritance

RIBase > RIClip | RIMaterialComponent | RIMaterialComponent | RINode | RISkeletonComponent | RIVisemeComponent 
RIBase > RIObject > RIAvatar | RICamera | RIParticle | RIProp 
RIBase > RIObject > RILight > RIDirectionalLight | RIPointLight | RISpotLight

Member Functions

IsValid ( self )

Check whether or not the scene object exists; If detection fails, return False.

Returns

True if valid, else False - bool

 2 event_callback = None
