==Examples==
{{Lua_example |
  description          = Adds a trail onto entity "ent".|
  useOn                = {{Serverside}}|
  code                 = <lua>local trail = util.SpriteTrail(ent, 0, Color(255,0,0), false, 15, 1, 4, 1/(15+1)*0.5, "trails/plasma.vmt")

</lua> |
}}

== Additional Notes ==
* For texture res, a good calculation is 1/(startWidth+endWidth)*0.5
* Not including the file extension may cause the game to crash.
* The function returns an env_spritetrail entity.
