Cannot teleport occupied boat.

It works fine when the boat is unoccupied. Here is the code I am using:

Code:

boatLoc = boat.getLocation();
       
        boatLoc.setYaw(shipOwner.getLocation().getYaw());
        boatLoc.setY(100);
       
        boat.teleport(boatLoc);

 

@Symphonic I've never tried it but it sounds like this would work:

Code:Java

 
Boat boat = ...; // Your boat
List<Entity> passengers = boat.getPassengers();
 
for (Entity entity : passengers) boat.removePassenger(entity);
 
Location location = ...; // Your location
boat.teleport(location);
 
for (Entity entity : passengers) boat.addPassenger(entity); // I'm not sure if this teleports the entities, otherwise you can do it manually

 

oh see this is high IQ

Edit: this does not work, and it does give some very seizure inducing teleportation behavior. :/

 

What happens?

 

The boat does not teleport, it stays put and the player is teleported in and out of the boat very fast and screen gets all vibratey because of it

 

@Symphonic Try using a BukkitRunnable to delay the teleport, and addPassenger loop by 1 tick.

 

@Symphonic If what KarimAKL says doesn't work, you could first destroy the boat, then spawn a new boat(with all your falling blocks) at the location(along with all the passenger stuff).

this is some code I use:

Code:java

 
    private static void teleportPlayer(@Nullable Player player, Location l) {
        if (player == null) return;
 
        ArrayList<LivingEntity> slaves = new ArrayList<>();
        for (Entity e : player.getWorld().getEntities()) {
            if (e instanceof LivingEntity) {
                LivingEntity livingEntity = (LivingEntity) e;
                if (livingEntity.isLeashed()) {
                    if (livingEntity.getLeashHolder() instanceof Player) {
                        if (livingEntity.getLeashHolder().getUniqueId().equals(player.getUniqueId())) {
                            slaves.add(livingEntity);
                            livingEntity.setLeashHolder(null);
                        }
                    }
                }
            }
        }
 
        LivingEntity horse = null;
        TreeSpecies boatType = null;
        Entity sailor = null;
        if (player.getVehicle() instanceof LivingEntity) {
            horse = (LivingEntity) player.getVehicle();
        } else if (player.getVehicle() instanceof Boat) {
            Boat b = (Boat) player.getVehicle();
            boatType = b.getWoodType();
            if (b.getPassengers().size() > 1) {
                sailor = b.getPassengers().get(1);
            }
            b.remove();
        }
 
        player.teleport(l);
 
        try {
            if (horse != null) {
                horse.teleport(player);
                horse.addPassenger(player);
            } else if (boatType != null) {
                Boat b = player.getWorld().spawn(player.getLocation(), Boat.class);
                b.setWoodType(boatType);
                b.teleport(player);
                b.addPassenger(player);
                if (sailor != null) {
                    sailor.teleport(player);
                    b.addPassenger(sailor);
                }
            }
        } catch (Exception ex) {
            ex.printStackTrace();
        }
 
        for (LivingEntity e : slaves) {
            try {
                e.teleport(player);
                e.setLeashHolder(player);
            } catch (Exception ex) {
                ex.printStackTrace();
            }
        }
    }
 

This is for horses/llamas/donkeys aswell, and for entities on a leash

The LivingEntity horse is the horse/llama
The TreeSpecies boatType is the boat you are in
The Entity sailor is the passenger in the boat with you
The ArrayList<LivingEntity> slaves are the entities on a leash

In some cases the sailor would dissapear for the teleported player, but when he rejoins the server its back. For other players (who just watch the teleport) its all fine

I hope this helps you in the right way

 

The issue is i'm trying to do this very fast every tick and this isnt gonna do that very well

 

bump

 

@Symphonic you could have the boat be a passenger of an arrow, and then use the launchprojectile method to launch it into the air/move it.
docs on vectors here: https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/util/Vector.html
EDIT: You can actually use the boat as the projectile

 

Will this interfere with normal movement of the boat? e.g. if the player in the boat presses W when this is happening will the boat move? forward as well as the launchprojectile direction?

 

@Symphonic likely not, basically what this is doing is "pushing it" in a certain direction.
You could probably make it that way if you need.

EDIT: I also just realized that the player can't move a boat forward in the air, but you could probably check for the oars moving.
