Projectile Trails

CompProperties_ProjectileTrail can be attached to any projectile's ThingDef in order to allow to attach or spawn flecks, motes, effecters and sustainers. You can also make your projectile have an athena beam linking them and their firer. This looks the best on high-speed projectiles as the beam will look unnatural if the firer moves while the projectile is in flight.

Beam def must be have a Beam thingClass or be a subclass of a Beam
