MCPVP GRAPPLER QUESTIONS

Code:

@EventHandler(priority = EventPriority.NORMAL, ignoreCancelled = true)
    public void onPlayerFish(PlayerFishEvent event) {
        final Player player = event.getPlayer();
        if (player.getItemInHand().getItemMeta().getDisplayName()
                .equals("Grapple Rod")) {
            event.getHook().setBounce(false);
            if (event.getState().equals(PlayerFishEvent.State.IN_GROUND)) {
                Location lc = player.getLocation();
                Location to = event.getHook().getLocation();
                lc.setY(lc.getY() + 0.5D);
                player.teleport(lc);
                double g = -0.08D;

    }

Hi, I'm having trouble with mcpvp's grappler. If you don't know what I'm talking about watch this video .

My first question is how do I make the bobber to hook on walls? Normal fishing rod can't hook on the walls, I wonder if there is a way to do that.

My second question is there a way to make the line go longer and faster?

My final question is how can I make the throwing tool leash/lead instead of the fishing rod? Thank you.

For your questions:
1. Extend EntityFishingHook (not sure about this one)
2. ent.setVelocity(ent.getVelocity().multiply(speed));
3. You cant launch fishing hook entity with bukkit... youll have to create your own one, and launch it when you need it. Theres a theard in the forums that ChaseChocolate replied in with a code for extended entity fishing hook that you can just launch...
