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, e.g. deletion, undo/redo operations, file importation, etc. Therefore, RIBase provides IsValid() to detect for scene objects' validity.

Member Functions

IsValid ( self )

Check whether or not the scene object exists; If detection fails, return False. Call IsValid() to determine the validity of the object or use an EventCallback to update the state of the object after an event is triggered.

Returns

Valid or not - bool
import RLPy

avatar = None
event_callback = None

class REventCallbackSampleCode(RLPy.REventCallback):
    def __init__(self):
        RLPy.REventCallback.__init__(self)
    def OnObjectDeleted(self):
        global avatar
        if not avatar.IsValid():
            print ("The avatar has been deleted")

def run_script():
    global avatar
    global event_callback
    avatar_list = RLPy.RScene.GetAvatars()
    avatar = avatar_list[0] 
    event_callback = REventCallbackSampleCode()
    id = RLPy.REventHandler.RegisterCallback(event_callback)
