    Hello Community,

    nearly everyone who's watching this Thread is asking himself how to create a balloon that a Player can hold in its hand.

    I'm really sorry for my bad english.

    Image of it (open)


    I tried this only for 1.8.8

    So, let's begin.

    At first, you have to create a Ballon class with a constructor and the following variables and methods:
    Code:
    public class Ballon {[/COLOR][/LEFT]
    [COLOR=rgb(44, 44, 44)]
    [LEFT]
        public Player player;
        public ItemStack block;
        public FallingBlock fallingBlock;
        public Bat bat;
        public boolean active = false;
    
        public static HashMap<Player, Ballon> balloonHashMap = new HashMap<Player, Ballon>();
    
    public Ballon(Player player, ItemStack block) {
            this.player = player;
            this.block = block;
        }


    You can also generate Getter's and Setter's if you want.

    So now create a method called "spawn".
    Code:
     public void spawn() {[/COLOR][/LEFT]
    [COLOR=rgb(44, 44, 44)]
    [LEFT]        active = true;
            balloonHashMap.put(player, this);
    }


    Now you have to create the Falling Block and the Bat. The Bat is there that you can leash the block later.
    Code:
    final FallingBlock[] fallingBlock = {player.getWorld().spawnFallingBlock(player.getLocation().add(0.0D, 2.0D, 0.0D), this.block.getType(), this.block.getData().getData())};[/COLOR][/LEFT]
    [COLOR=rgb(44, 44, 44)]
    [LEFT]        Bat bat = (Bat)player.getWorld().spawnEntity(player.getLocation().add(0.0D, 2.0D, 0.0D), EntityType.BAT);


    So, now you have to set some parameters for the Bat and the Falling Block:
    Code:
      fallingBlock[0].setDropItem(false);[/COLOR][/LEFT]
    [COLOR=rgb(44, 44, 44)]
    [LEFT]        bat.setPassenger(fallingBlock[0]);
            bat.setRemoveWhenFarAway(false);
            bat.setLeashHolder(player);
            bat.setCanPickupItems(false);
            bat.addPotionEffect(new PotionEffect(PotionEffectType.INVISIBILITY, Integer.MAX_VALUE, 255));
    NBTTagCompound compound = new NBTTagCompound();
    ((CraftEntity)bat).getHandle().e(compound);
    compound.setInt("Silent", 1);
    ((CraftEntity)bat).getHandle().f(compound);
    NBTTagCompound tag = new NBTTagCompound();
    ((CraftEntity)fallingBlock[0]).getHandle().e(tag);
    tag.setInt("Time", 1);
    ((CraftEntity)fallingBlock[0]).getHandle().f(tag);
    


    When you've got that, you have to initialize the Bat and the Falling Block in the class:
    Code:
     this.bat = bat;[/COLOR][/LEFT]
    [COLOR=rgb(44, 44, 44)]
    [LEFT]        this.fallingBlock = fallingBlock[0];


    Then create a BukkitRunnable(Timer Task) with 2L delay and 2L period.
    Code:
    new BukkitRunnable() {[/COLOR][/LEFT]
    [COLOR=rgb(44, 44, 44)]
    [LEFT]            @Override
                public void run() {}
            }.runTaskTimer(Main.getPlugin(Main.class),2L,2L);


    So now you need the "active" boolean:
    Code:
     if(active) {[/COLOR][/LEFT]
    [COLOR=rgb(44, 44, 44)]
    [LEFT]} else {
           despawn();
           cancel();
    }

    I'll get later to that despawn thing.

    ** Now: In the "active" if-clause **

    ----------
    Code:
    if(active) {
    ----------

    So now you have to ask if the Bat is(n't) leashed.
    Code:
    if(!bat.isLeashed()) {[/COLOR][/LEFT]
    [COLOR=rgb(44, 44, 44)]
    [LEFT]                        despawn();
                            cancel();
                        }


    Then you have to do the same thing as above:
    Code:
    NBTTagCompound tag = new NBTTagCompound();[/COLOR][/LEFT]
    [COLOR=rgb(44, 44, 44)]
    [LEFT]                    ((CraftEntity)fallingBlock[0]).getHandle().e(tag);
                        tag.setInt("Time", 1);
                        ((CraftEntity)fallingBlock[0]).getHandle().f(tag);


    Now check if the Falling Block is on the ground and if it's null:
    Code:
    NBTTagCompound tag = new NBTTagCompound();[/COLOR][/LEFT]
    [COLOR=rgb(44, 44, 44)]
    [LEFT]                    ((CraftEntity)fallingBlock[0]).getHandle().e(tag);
                        tag.setInt("Time", 1);
                        ((CraftEntity)fallingBlock[0]).getHandle().f(tag);
    if(fallingBlock[0] == null) {
        fallingBlock[0] = player.getWorld().spawnFallingBlock(player.getLocation().add(0.0D, 2.0D, 0.0D), block.getType(), block.getData().getData());
        bat.setPassenger(fallingBlock[0]);
        fallingBlock[0].setDropItem(false);
    }
    


    Now check if the Bat' distance to the player is above "3.0":
    Code:
    if(bat.getLocation().distance(player.getLocation()) > 3.0D) {[/COLOR][/LEFT]
    [COLOR=rgb(44, 44, 44)]
    [LEFT]                        bat.setVelocity(new Vector(player.getLocation().getX() - bat.getLocation().getX()
                            , player.getLocation().getY() - bat.getLocation().getY(),
                                    player.getLocation().getZ() - bat.getLocation().getZ()).normalize().multiply(0.5D));
                        } else {
                            bat.setVelocity(new Vector(0,0,0));
                        }
                       


    Now check if the Bat's distance to the player is above "6.0":

    Code:
      if(bat.getLocation().distance(player.getLocation()) > 6.0D) {[/COLOR][/LEFT]
    [COLOR=rgb(44, 44, 44)]
    [LEFT]                        bat.setVelocity(new Vector(player.getLocation().getX() - bat.getLocation().getX()
                                    , player.getLocation().getY() - bat.getLocation().getY(),
                                    player.getLocation().getZ() - bat.getLocation().getZ()).normalize().multiply(1.25D));
                        }


    Now check players eye location with the bat's y location:
    Code:
    if (player.getEyeLocation().getY() - bat.getLocation().getY() >= 0.125D) {[/COLOR][/LEFT]
    [COLOR=rgb(44, 44, 44)]
    [LEFT]                        bat.setVelocity(new Vector(0.0D, 0.5D, 0.0D));
                        }


    And finally do a try catch for the "setPassenger" method:
    Code:
    try {[/COLOR][/LEFT]
    [COLOR=rgb(44, 44, 44)]
    [LEFT]                        bat.setPassenger(fallingBlock[0]);
                        } catch(Exception e1) {
                            fallingBlock[0].getLocation().getBlock().setType(Material.AIR);
                            fallingBlock[0] = player.getWorld().spawnFallingBlock(player.getLocation().add(0.0D, 2.0D, 0.0D), block.getType(), block.getData().getData());
                            bat.setPassenger(fallingBlock[0]);
                            fallingBlock[0].setDropItem(false);
                        }



    --------
    Code:
    } else {
    --------

    So now insert "despawn" and "cancel" if active isn't true:
    Code:
    despawn();[/COLOR][/LEFT]
    [COLOR=rgb(44, 44, 44)]
    [LEFT]                    cancel();


    -------
    Code:
    }
    -------


    That was the "spawn" method, now finally to the despawn method:

    Set boolean "active" to false.
    Set the leash holder of bat to null.
    Remove the Falling Block.
    Remove the Bat.
    And remove the player from the balloonHashMap.
    Code:
     public void despawn() {[/COLOR][/LEFT]
    [COLOR=rgb(44, 44, 44)]
    [LEFT]        active = false;
            bat.setLeashHolder(null);
            fallingBlock.remove();
            bat.remove();
            Ballons.ballonHashMap.remove(player);
        }



    Thank you for watching my Thread.

    Plugin.
    You put it in a class, you need to make the spawning yourself.
    Might be better for you to make a plugin request.

    Now i try it in Eclipse, but it gives me no import-options for "Player" and "FallingBlock".
    What are the matching classes (names) in minecraft 1.13.2

    third code-box:

    this.block.getType(), this.block.getData()

    in 1.13.2 the class EntityFallingBlock does not have the methods gerType and getData any more.
    What are the right methodes to replace them

    And also player.getLocation is not more known.
    And spawnEntity is not more compatible with the argunents there.
    what must i use there?
