Control mob speed and direction?

Hey guys, JBoss925 here. I've been playing around with riding entities. I want to make a plugin that will move a sheep you are riding in the direction you are looking when you right click with bread in your hand. Basically, I want to just have the sheep move in the direction a player is looking which is what I'm having trouble with. Here's my code I'm using to try to control the sheep:

Code:java

public void onPlayerInteract(PlayerInteractEvent e){
        if(e.getAction() == Action.RIGHT_CLICK_BLOCK || e.getAction() == Action.RIGHT_CLICK_AIR){
            if(e.getPlayer().getVehicle().getType() == EntityType.SHEEP){
                Sheep en = (Sheep) e.getPlayer().getVehicle();
                Player p = e.getPlayer();
                if(p.getItemInHand().getType() == Material.BREAD){
                    Vector v = p.getLocation().getDirection().multiply(5);
                    en.setVelocity(v);
                }
            }
        }
    }

 

And the problem is...?
