    hey everyone. i was wondering how one would go about updating a python plugin by checking for a frame change? any help is greatly appreciated. im running into trouble because when i have the object cache optimization turned on, i cant seem to update or check for anything once the cache has been built. how to i get it to update the cache on a frame by frame basis?

    Hi avd007, in your case turn of the "Optimize Cache" attribute of your Python Generator so
    it will be triggered on all events. To avoid a massive slowdown of your generator for complexe
    geometry add the two lines #1, #2 to your generator which do the same as "Optimize Cache".
    But now you can add custom conditions when you return the cache of your object.

    import c4d
    #Welcome to the world of Python
      
    def main() :
        dirty = op.CheckCache(hh) or op.IsDirty(c4d.DIRTY_DATA) #1
        if dirty is False and not framechanged and ... : return op.GetCache(hh) #2
        
        return c4d.BaseObject(c4d.Ocube)

    You could also check if the frame did really change.

    prev        = type("", (), {})()     # create a new empty type and instantiate it  
    prev.frame  = 0  
    prev.cache  = None  
      
    def **main** () :  
      frame   = doc.GetTime().GetFrame(doc.GetFps())  
      if frame != prev.frame:  
          prev.frame  = frame  
          # continue ..  
            prev.cache  = objectToReturn  
          return objectToReturn  
      else:  
          return prev.cache
