My scene exits pass the local player offset (from the exit) to the SceneManagement script. This information is retrieved by the new scene entrance. This is to help give a sense of continuity between scenes.
My particle system uses a local space simulation, so the scene exit can be rotated, and the particles will fire in the right direction. Since I will be rotating my scene exists, there is no need for me to micromanage the local position of my scene entrances.
For my particle system, I imported a star sprite to make my own star particle. I also used plane collision to prevent the particles from veering too far.
