Calling Bump (figured out, I think)

I was trying to define my own density variable so that I could have differnt types of density and I got it to work, except that Bump is not called. Is there something else that has to be done?

turf
  Enter(atom/movable/e)
    var/d = get_dir(src,e) //Get the direction of the object moving onto the turf
    if(!ChkDen(e)||!ChkEnter(d)) 
      e.Bump(src) //Added this to call bump, but is there something else I should do? 
                 //Now it calls Bump twice instead of not at all...
      return 0
    else return ..()

turf
  proc
    ChkDen(atom/movable/e) //Checks for density and special density
      if(src.density) return 0
      if(e.pwall&&pwall) return 0
      else return 1

    ChkEnter(d) //Checks to see if an object can enter
      if(d && (dir_to_bitflag[d] & tbit)) return 0 //Directional Blocking
      else if(d&(d-1)) return 0 //Block Diag
      else return 1

Instead of using something like <code>Bump()</code>, you may want to override the <code>Move()</code> proc alltoghether.

atom
    var
        density2=0
    movable
        Move(atom/newloc,newdir)
            .=..()
            if(.)
                var/atom/A=newloc.loc
                if(!A)A=newloc
    
                if(A.density2>=src.density2).=0
                for(var/atom/X in A.contents)
                    if(X.density2>=src.density)
                        .=0
                        break


This creates a <code>density2</code> variable. If it's equal or higher, the object is considered dense.

Now that I look at it more closely, you may be wanting to block directions. Here's a version for directions:

turf
    var
        //by default, only allow cardinal directions
        enter=NORTH|SOUTH|EAST|WEST
        exit=NORTH|SOUTH|EAST|WEST
    Enter(atom/movable/M)
        if(M.dir&enter)return ..()
    Exit(atom/movable/M)
        if(M.dir&exit)return ..()


I hope I helped ya.
