Launch-Pad Movement

Hello,
i am trying to make a Launch-Pad plugin. With some research i found this:

Code:

private static final MaterialData PISTON = new MaterialData(Material.MOVING_PISTON);

    @EventHandler
    public void onMove(PlayerMoveEvent event) {
        Block block = event.getTo().clone().subtract(0,1,0).getBlock();
        JumpPadManager manager = new JumpPadManager(block);
        if(block.getType() != Material.SLIME_BLOCK)
            return;
        if(!manager.isJumpPad())
            return;

        FallingBlock fallingBlock = event.getTo().getWorld().spawnFallingBlock(event.getTo(), PISTON.getItemType(), PISTON.getData());
        fallingBlock.setDropItem(false);
        fallingBlock.setCustomName("JumpPadEntity");

        Location launchLocation = event.getFrom().setDirection(event.getTo().toVector().subtract(event.getFrom().toVector())).clone();
        launchLocation.setPitch((float) -(manager.getMultiplier().getAngle()));
        launchLocation.setYaw(event.getTo().getYaw());
        fallingBlock.setVelocity(launchLocation.getDirection().normalize().multiply(manager.getMultiplier().getMultiplier()));

        launchPlayer(event.getPlayer(), fallingBlock);
    }

    private void launchPlayer(final Player player, final FallingBlock fallingBlock) {
        if (!player.getAllowFlight()) {
            player.setAllowFlight(true);
        }
        (new BukkitRunnable() {
            private boolean endFlight = false;

            private boolean ignoreFirstPlayerOnGround = true;

            public void run() {
                player.setFallDistance(0.0F);
                if (fallingBlock != null) {
                    fallingBlock.setTicksLived(1);
                    if (!player.getLocation().getWorld().equals(fallingBlock.getWorld()) || fallingBlock.getLocation().clone().add(fallingBlock.getLocation().getDirection().clone().multiply(0.5D)).getBlock().isLiquid())
                        endFlight = true;
                    if (!fallingBlock.isDead())
                        player.setVelocity(fallingBlock.getVelocity());
                }
                if(player.isSneaking())
                    endFlight = true;
                if ((player.isOnGround() && !ignoreFirstPlayerOnGround) || fallingBlock == null || fallingBlock.isOnGround() || fallingBlock.isDead() || fallingBlock.getLocation().getY() < -10.0D || fallingBlock.getVelocity().length() == 0.0D || endFlight || player.getLocation().getBlock().getType() == Material.LADDER) {
                    if (fallingBlock != null)
                        fallingBlock.remove();
                    if(player.getGameMode() != GameMode.CREATIVE && player.getGameMode() != GameMode.SPECTATOR)
                        player.setAllowFlight(false);
                    player.setFlying(false);
                    cancel();
                }
                ignoreFirstPlayerOnGround = false;
                fallingBlock.getLocation().setYaw(player.getLocation().getYaw());
            }
        }).runTaskTimer(Main.plugin, 0L, 1L);
    }

it also works, but i can't move/change direction when i'm in the air.
Is there any way to fix this?
(I thought of changing the direction of the falling block in that direction i look, but i don't know how to do it)

Thanks for help

 

As a good start you can do: player.getLocation().getDirection() which will give you a vector of where the player is looking.
