#1
mob/verb/rock()
   var/obj/o = 'rocks.dmi'
   new o(usr.loc)
   sleep(1)
   o.pixel_y += 2

#2
mob/verb/rock()
   var/obj/o = 'rocks.dmi'
   new o(usr.loc)
   while(o)
       sleep(1); o.pixel_y+=2


Those don't work. I get runtime errors.

RUNTIME ERROR FOR #1:
runtime error: Cannot create objects of type null.
proc name: rock (/mob/verb/rock)
  source file: Verbs.dm,130
  usr: \[Designer] SSJ4_Gohan_Majin (/mob/characters/Male_White)
  src: \[Designer] SSJ4_Gohan_Majin (/mob/characters/Male_White)
  call stack:
\[Designer] SSJ4_Gohan_Majin (/mob/characters/Male_White): rock()

RUNTIME ERROR FOR #2: SAME ERROR AS #1


Please help if you can, thanks!

You're trying to set an object reference equal to an icon file.

Try something like this:
/*  This defines what a rock is, sets an icon for them, and
    adds a Hover() proc which will make the rock rise into 
    the air, then vanish when it gets as high as the Height
    var which is passed to it.
*/

obj
  rock
    icon = 'rock.dmi'
    proc
      Hover(Height=10 as num)
        while(Height)
          pixel_y += 1
          Height--
          sleep(1)
        del src

/*  This verb simply creates a new rock in the usr's
    location, then calls the rocks Hover() proc.  You 
    can change the height of the hover to whatever you 
    want.
*/

mob
  verb
    Rock()
      var/obj/rock/Rock = new(loc)
      Rock.Hover(30)


There are a few problems with this snippet, but it's a start. You may not even see the rock at all, depending on how high you hover it, and how big your mob's icon is. The rock will be on a lower layer than the mob, so it may be behind it. Set the objects layer var to MOB_LAYER+1 to fix this temporarily.

You would also need to check to be sure Height is a valid
value. You wouldn't want a negative value to get passed, etc.
