Can someone help me out on making a Pushing/Pulling Verb?

Without offering specifics, this is the most I can give:

mob/verb
  Push()
    var/obj/O = locate() in get_step(src,src.dir)
    if(O)
      step(O,src.dir)

  Pull()
    var/obj/O = locate() in get_step(src,src.dir)
    if(O)
      step(src,turn(get_dir(O,src),180))
      step(O,turn(src.dir))

I feel guilty that I provided this code without explaining how it works. The last thing I want is a simple copy+paste job without you understanding what you've done. Here's a commented version:

mob/verb
> >   Push()
> >     var/obj/O = locate() in get_step(src,src.dir) // This assigns 'O' to the first object found in the turf directly in front of 'src'. If there is none, then it returns 'null'
> >     if(O) // If 'O' is NOT 'null'...
> >       step(O,src.dir) // Move the object one space in the direction that it was pushed
> > 
> >   Pull()
> >     var/obj/O = locate() in get_step(src,src.dir)
> >     if(O)
> >       step(src,turn(get_dir(O,src),180)) // This may be confusing. This moves 'src' one step away from the object, and the following line moves the object towards 'src', making the effect of the object being pulled

Hope that clarifies. Play around with the code to get a better understanding as to how it works. Trust me, the last thing you want to do is copy+paste code without knowing how it works.

He forgot to add the ",180" as the last paramiter.

Does step() check for dense objects before it moves something?

Push()
var/obj/O = locate() in get_step(src,src.dir)
if(O)
step(O,src.dir)

Pull()
var/obj/O = locate() in get_step(src,src.dir)
if(O)
step(src,turn(get_dir(O,src),180))
------->step(O,turn(src.dir))<-------


I PUT THAT but it says Turn:Expected 2 arguments found 1 one the one pointed to!

It uses Move(), so yes.

It means it's expecting 2 arguments for turn(), not for step(). You need to add the argument after src.dir; for example:

<code>step(O,turn(src.dir, 180))</code>

Don't bump your post three times within six hours. This is a FORUM, not a chatroom. If you hadn't been so rude about bumping, I might actually be inclined to help you.

icon_state = "Rock1"

Push()
set src in oview(1)
var/obj/O = locate() in get_step(usr,usr.dir)
if(O)
step(O,usr.dir)
step(usr,O.dir)
Pull()
set src in oview(1)
var/obj/O = locate() in get_step(usr,usr.dir)
if(O)
step(usr,turn(get_dir(O,src),180))
step(O,turn(usr.dir,180))
