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, RIBaseprovides IsValid to detect for scene objects' validity.
Member Functions
IsValid ( self )
Check whether or not the scene object exists; If detection fails, return False.
Returns
- True if valid, else False - bool
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)
