I would like somone to create a demo on turning beam proc for a dbz games a actual homing beam, although i'm not to particular to math this factor bewilders me.


sequances beam finds usr Y.axis stops turns usr.X axis stops when aligned proceeds usr.dir contact dmg.

------
i
i
i
-------[X].dmg

all dir.

mob/verb/Doom(mob/m in view())
    set name="TURNING BEAM OF DOOM"
    set category="Ultra Cool Moves"
    var/obj/beam/b=new/obj/beam
    if(m.y>b.y)b.dir=NORTH
    else b.dir=SOUTH
    view()<<"<B>TURNING BEAM OF DOOM!"
    while(src.y!=b.y)step(b,b.dir)
    //Now Its at the Y value of the person
    if(m.x>b.x)b.dir=EAST
    else b.dir=WEST
    while(src.x!=b.x)step(b,b.dir)

Your new statement needs parenthesis.
var/obj/beam/b = new()


Your while statements are checking the beams location against the 'src'. I am pretty sure you should be checking it against 'm'.

You need some sort of sleep statement in the while statements.

Also you should close your html tag.

Perhaps something like this:
mob/verb/US_Beam(mob/m in oview())
  set name="Turning Beam of Upset Stomach"
  set category="Relatively Cool Moves"
  var/obj/beam/b=new(src.loc)
  var/d=get_dir(b,m)
  b.dir=(d&(d-1))^d
  viewers(,b)<<"<B>Behold! The Turning Beam of Upset Stomach</B>"
  while(b.y!=m.y) 
    step(b,b.dir) 
    sleep(1)
  b.dir=d&(d-1)
  while(b.x!=m.x) 
    step(b,b.dir) 
    sleep(1)

Oh yeah good point i rushed it, that'd make a single beam thats no where, if your a decent coder you can figure it out though.

**edit**
wth is <dmb.dir=(d&(d-1))^d</dm>

d if d is a cardinal direction, or the NORTH/SOUTH component of d if it isn't.
