Solved GetHighestBlockAt

PHP:

    public function execute(CommandSender $sender, string $commandLabel, array $args) : bool{
        if(!$sender instanceof Player){
            $sender->sendMessage(C::RED . "Please use this command ingame.");
            return false;
        }
        $world = $this->getServer()->getLevelByName("world");
        $x = rand(1,9999);
        $z = rand(1,9999);
        $y = $world->getHighestBlockAt($x + 5, $z + 5);

        $sender->teleport(new Position($x, $y, $z));

        return true;
    }

not workinf teleports me to bedrock

 

Maybe this is a chunk rendering problem, i mean, you need to render the block before processing the event, (but i'm not sure)

 

If the chunk was never loaded (a totally fresh chunk), Level::getHighestBlockAt() returns -1.

 

that's what I wanted to say, but you are more specific.

 

How do I load it

 

you need to go to this area, actually i don't know exactly how to load them whitout going to the area or if has an way to load that.

 

Thx sm
