Please show the entire class code so that we can determine how to fix it.

First thing is that lines 27 through 30 do not do a thing (if at ground level, set at ground level?). Better would be to set the actor at ground level if below ground level. Change the '==' in line 27 to '>'. Next thing is you currently only have vertical movement for the actor, so the blockade will therefore either be hit on the underside or landed on. Since no information on what you are aiming at is given, I will only give what is needed for hitting the underside of a blockade (you are calling it a blockade and only have vertical movement). Change your blocade method to this:

public void blocade()
{
    Actor box = getOneIntersectingObject(Boxes.class);
    if (box != null)
    {
        setLocation(getX(), box.getY()+(box.getImage().getHeight()+this.getImage().getHeight())/2+1);
        ySpeed = 0;
}

I have done it, but when I touch the Boxes class I fall down under the Boxes

Is that not what you wanted? If the actor does not move horizontally and only jumps, then the blockade must be above it and therefore, the actor will hit the underside and fall back to ground level.

No I want to jump on the Boxes that I can jump from on Box to the other.

So, you want to be able to jump up through the box and then land on it?

You will never land on it if the actor cannot move horizontally.
