/* This is an attempt to make some easily reusable "particle" type effect, to stop the code
|
|
constantly having to be rewritten. An item like the jetpack that uses the ion_trail_follow system, just has one
|
|
defined, then set up when it is created with New(). Then this same system can just be reused each time
|
|
it needs to create more trails.A beaker could have a steam_trail_follow system set up, then the steam
|
|
would spawn and follow the beaker, even if it is carried or thrown.
