Code:
world
    view = 21
mob
    icon = 'male.dmi'
mob
    Login()
        src.loc = locate(1,1,1)
        sleep(10)
        src.gravity()
atom/movable/Move()
    if(dir == 1)
        var/obj/block/block
        for(block in locate(src.x,src.y-1,src.z))
            jump()
            return ..()
        if(src.y<2)
            jump()
            return ..()
    else
        return ..()
mob
    proc
        gravity()
            if(src.y>=2)
                takedown()
            sleep(10)
            src.gravity()
mob
    proc
        takedown()
            spawn(5) usr.y -= 1
atom
    proc
        jump()
            spawn(1) usr.y++
            spawn(3) usr.y++
            spawn(5) usr.y++
            spawn(7) usr.y++
turf
    floor
        blackness
            icon = 'blackness.dmi'
atom
    var
        jumpover = 1
        canjump = 0
        activategrav = 1
obj
    block
        density = 1
        icon = 'block.dmi'
    notblock
        density = 0
        icon = 'block.dmi'


Problem description:
The gravity works, the user jumps and goes up a 4 blocks, *Trying to make a game based around this*
But when the users jumped, he cannot scroll to left or right.
he will jump and go down, any ideas?
By the way, when hes landed back onto Y 1, he can move again, and when hes landed on a few blocks i put in the air.

If I had to guess, I would say that the problem is with how your gravity proc is working... I would try:
mob
    Login()
        src.loc = locate(1,1,1)
        sleep(10)
        spawn() src.gravity()

    proc
        gravity()
            if(src.y>=2)
                takedown()
            spawn(10) src.gravity()

I'm not sure why you're sleeping in Login(), and I'm not too fond of calling "takedown()" unless you use it more than just in that one spot... but those are just minor details...

Darn, didnt work, i tryed it, i forget why i put gravity with a sleep.


Gravity system, a pain :|

Thanks for trying

Now that I'm off work, I was messing around with it a bit... the actual functionality of it is a bit strange, but in any case, I did notice that you're checking if(dir == 1)... but without the Move() actually taking place, the direction the mob is facing stays the same. After changing it to:
atom/movable/Move(NewLoc, Dir)
    if(Dir == 1)

You can move while the gravity stuff is taking place.
