Investigate alternatives for adding bullets/particles

[JeremyLeland]

Currently, we pass a Level object to every Actor so it can call Level.addParticle and Level.addBullet. Is there a better way to do this?

• We could pass the bullet and particle lists in as objects, but then we have to do all editing on the list itself
• Would some sort of static Level object make sense? It feels odd/inelegant, but it may be the best way to do it...just take another look later.

Maybe have all Actors keep a local list of particles/actors generated, and the level retrieves them every update cycle?

[JeremyLeland]

If we no longer give actors a link to the level, we’ll need to pass them lists of nearby entities somehow. Maybe on update?

maybe this is what makes actors different than entities — they get called with a list of nearby objects, so they can take actions based on them?

Should have been fixed by comment (guess I need separate fix statements for each issue)
