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 ...

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.
