Solved is world.loadChunk(int x, int z, boolean regen); async? (Make random Teleport 1.14)

Hey, i have only a short question. I will make a random TP for my Server-Ssystem. But the Problem is, randomly players gets teleported in the ground. I think the issue is that, thats the koordinate gets savechecked before the chunk is complete generated. Now my question, is world.loadChunk async? if yes a must create a bukkit task that runs later.


Here my code

Code (Java):

/**
     * Errechnet eine sichere Position.
     *
     * @param player {@link Player}
     * @param world  {@link World}
     * @param max_x  {@link Integer}
     * @param max_z  {@link Integer}
     * @return {@link Location} und null wenn unsicher.
     */
    private Location getGoodLocation(World world, int max_x, int max_z) {
        Location teleportlocation = null;
        Random random = new Random();
        int x = random.nextInt(max_x);
        int y = 170;
        int z = random.nextInt(max_z);
        Location targetlocation = new Location(world, x, y, z);
        targetlocation.getWorld().loadChunk(x, y, true);
        while (targetlocation.getBlockY() > 0) {
            Block block = targetlocation.getBlock();
            if (block.getType() == Material.LAVA || block.getType() == Material.WATER
                    || block.getType() == Material.CACTUS) {
                break;
            } else if (block.getType() == Material.AIR) {
                targetlocation.subtract(0.0, 1.0, 0.0);
            } else if (block.getType() != Material.AIR) {
                teleportlocation = targetlocation;
                break;
            }
        }
        if (teleportlocation != null) {
            return teleportlocation.add(0.0, 1.0, 0.0);
        } else {
            return null;
        }
    }

Iam enjoyed for any suggestions or help.

 

Ok? Why this code let players spawn into the ground? Have a solution for it?

 

Ok? Also instead of int y = 170; int i = world.getHigestBlockAt().getY; ?

 

Thanks i will try it

 

Not work i get stuck in the ground

Code (Java):

private Location getGoodLocation(World world, int max_x, int max_z) {
        Location teleportlocation = null;
        Random random = new Random();
        int x = random.nextInt(max_x);
        int z = random.nextInt(max_z);
        world.loadChunk(x, z, true);
        int y = world.getHighestBlockYAt(x, z);
        Location targetlocation = new Location(world, x, y, z).subtract(0.0, 1.0, 0.0);
        Block block = targetlocation.getBlock();
        if(block.getType() != Material.WATER && block.getType() != Material.LAVA) {
            teleportlocation = targetlocation;
        }
        return teleportlocation;
    }

 

It is like the world gets generated around me

 

Thanks! I have fixed the random Teleport. Thank you so mush.

 

Yea. Simple get the highest block in the world int y = world.getHighestBlockYAt(x, z);
then get the blockface down from the location and check whatever you want. then teleport the player.

 

Thanks
