| /datum/effect/trail | ///// Attach an Ion trail to any object, that spawns when it moves (like for the jetpack) just pass in the object to attach it to in set_up Then do start() to start it and stop() to stop it, obviously and don't call start() in a loop that will be repeated otherwise it'll get spammed! |
| /datum/effect/trail/steam | Attach a steam trail to an object (eg. a reacting beaker) that will follow it |
