Hi,

I need a way to remove all the children of a BaseObject

This is what I currently have

    
    
    
    
    
    
    
    void RemoveChildObjects(BaseObject* op)
    
    
    
    
    {
    
    
    
    
    BaseObject *child = op->GetDown();
    
    
    
    
    while(child)
    
    
    
    
    {
    
    
    
    
    child->Remove();
    
    
    
    
    BaseObject::Free(child);
    
    
    
    
    child=child->GetNext();
    
    
    
    
    }
    
    
    
    
    }

But that doesn't work because child becomes NULL after the first BaseObject::Free

get the child before you remove the original.

BaseObject* temp;
while(child)
{
temp = child->GetNext();
child->Remove();
BaseObject::Free(child);
child = temp;
}

I have a question indirect to this discussion. Every time that I Remove() something from a document and try to Free() it, Cinema 4D crashes (Objects, Tags, Materials, you name it). I have since determined that either Cinema 4D handles the deallocation or it is also possible that as long as the object is tied to an Undo, it cannot be deleted (thereafter handled by Cinema 4D). I always add AddUndo(UNDO_NEW) when inserting just-created objects. Could this be why I can't Remove()-Free()?

Hi Kuro,

I don´t think it could be the cause for the crashing. Maybe another plugin is the cause? Try to remove all other plugins, this may help sometimes. Otherwise I don´t see a reason for crashing with Remove & Free(). Never has this issue.
