Are you using forum_account's pixel movement or Sidescroller?
mob
    bump()
        ..()
        if(can_jump())
            jump()

Something like that.

No its entirely mine code using byond built in pixel movement and I think you didn't got what I am trying to do I am trying to make that if user bump into densed turf they will jump over it something like pokemon

Yeah, he got what you wanted. I recommend using forum_account's Pixel Movement library. It handles this for you, and all you have to do is write the code Kaiochao mentioned above.

One method to do this in the "Pokemon style" ridges where they don't actually have a third-dimension to "jump" within is to simply play a "hop" animation. You can also use Enter() to determine if they're approaching from the correct direction like in Pokemon.

Here's an example implementation. You were rather vague, so I took some liberties:
turf
    Ridge
        name = "Ridge"
        icon = 'Ridges.dmi'
        density = 0 // We use Enter() to manually control density
        
        Entered(atom/movable/A,atom/oldLoc)
            
            if(istype(A,/mob))
                // Play the jumping animation for players
                flick("hop", A)
            
            spawn(1)
                // Try to step them over the ridge
                var/direction = get_dir(oldLoc, src)
                var/success = step(A, direction)
                
                if(!success)
                    // If it fails (something in the way), send them back
                    A.Move(oldLoc, direction)
        
        Directional
            icon_state = "directional"
            North/dir = NORTH
            South/dir = SOUTH
            East/dir = EAST
            West/dir = WEST
            
            // Make this turf enterable from only one direction
            Enter(atom/movable/A, atom/oldLoc)
                
                // Check they're coming from the right dir
                if(get_dir(oldLoc, src) != src.dir)
                    return 0 // Block entry
                
                // Do the standard checks for dense objects
                return ..()
