This example would trigger a Trackview Sequence when pressing Ctrl+G in the editor or Launching the level.
A Track Event is a one-way signal that will allow you to branch Flowgraph logic from a Trackview Sequence. First you will have to set it up in the Trackview, without that you cannot use this flownode. You can read more about the setup in the Using Track Events page.
In this example the predefined events are triggering Particle Effects to start and to stop.
