Move()
            if(!src.canmove)
                return
            ..()
            var/oldloc=src.loc
            var/olddir=src.dir
            var/owned=src.owner
            var/obj/trail/N=new/obj/trail
            N.loc=oldloc
            N.dir=olddir


this produces trails but i want to know how to handle the trails turning smoothly as in a transition from north to east provides a new trail to mkae it look joint together. at the moment i get this:

Make the diagonal icon states the connecting icon states and then set the dir to that connecting state (ex: if the beam was going north than it turned east, make the icon state northeast).

This is done rather easily: 
 if(!src.canmove)
                del src  //  Why keep it when there's no point?
            var
                oldloc = src.loc
                olddir = src.dir
            .=..()  //  After this, the src.loc is NOT the same as oldloc (if the Move() is successful)!
            if(!(.)) del src  //  If it cannot move, get rid of it
            var/obj/trail/N = new(oldloc)  //  Makes a new trail at the old location
            N.owner = src.owner
            N.dir = olddir
            if(src.dir != olddir)  //  If the direction changed. 
                N.dir |= src.dir   //  Bit operation. If the old dir was NORTH, new dir is EAST, this does NORTH|EAST = NORTHEAST

In response to GhostAnime (#1)
ah thanks. especially for the comments about how to improve other things that i had coded in.
