   Hi I am trying to create a fireworks effect with Flint and the FlarToolKit , how would I start the emitter only when my base node for Flar is showing
   any help would be appreciated. here is the good that I have so far.
   Thanks

   Hi
   
   I don't know the FlarToolkit, so can't be specific on this, but
   
   emitterReference.start()
   
   is what starts the emitter.

   Hi yea the emitter starts I am having issues trying to add it to the base node.
