Solved How to jump a player to a specific position

Hi,
I'm trying to make a plugin which shoots the player from anywhere through the air to a specific position (for example 107, 71, 17).
I don't want to teleport the player, more like a jump boost that the player is flying.
How can I do that?

setMotion()
And the server will kick the player because of Flying not enabled.

Entity::knockBack() and your client may crash if $base is too high

I've already tried setMotion, but the problem is that you can't set coordinates in setMotion. I don't know how to calculate it correctly that the player exactly lands on the specific position. Same problem with ->knockBack(), it would be really difficult to set it on the right values that the player lands on the correct position. How to do that?

Some random math, will ask @Aodzip

Check EssentialsPE's /jump

Code:

<?php
namespace EssentialsPE\Commands;

use EssentialsPE\BaseFiles\BaseAPI;
use EssentialsPE\BaseFiles\BaseCommand;
use pocketmine\command\CommandSender;
use pocketmine\Player;
use pocketmine\utils\TextFormat;

class Jump extends BaseCommand{
    /**
     * @param BaseAPI $api
     */
    public function __construct(BaseAPI $api){
        parent::__construct($api, "jump", "Teleport you to the block you're looking at", null, false, ["j", "jumpto"]);
        $this->setPermission("essentials.jump");
    }

    /**
     * @param CommandSender $sender
     * @param string $alias
     * @param array $args
     * @return bool
     */
    public function execute(CommandSender $sender, $alias, array $args){
        if(!$this->testPermission($sender)){
            return false;
        }
        if(!$sender instanceof Player || count($args) !== 0){
            $this->sendUsage($sender, $alias);
            return false;
        }
        $block = $sender->getTargetBlock(100, BaseAPI::NON_SOLID_BLOCKS);
        if($block === null){
            $sender->sendMessage(TextFormat::RED . "There isn't a reachable block");
            return false;
        }
        if(!$sender->getLevel()->getBlock($block->add(0, 2))->isSolid()){
            $sender->teleport($block->add(0, 1));
            return true;
        }
        switch($side = $sender->getDirection()){
            case 0:
            case 1:
                $side += 3;
                break;
            case 3:
                $side += 2;
                break;
            default:
                break;
        }
        if(!$block->getSide($side)->isSolid()){
            $sender->teleport($block);
        }
        return true;
    }
}

I think thats only a extended teleport function, but not a jump function like I mean.
I mean something like Knockback Jump Pads through the air, but not teleport.

I researched a bit and got it working, you have to calculate the coordinate change when a player has an x and y velocity of 1, I pasted the result in a file and used it to calculate with it, here is the code, it works well:

PHP:


$pl = $event->getPlayer();



// + 6.5235748291016 x


$wishX = 87;
$wishZ = 49;

$x = ($wishX - $pl->x) / 6.5235748291016;
$z = ($wishZ - $pl->z) / 6.5235748291016;

$pl->setMotion(new Vector3($x, 1, $z));




$wishX and $wishZ are the coordinates the player should get teleported to.

Thank you, it works great!

One more question: In the lobby, players are in survival game mode. So they are always kicked for flying.
When I do:

$pl->setAllowFlight(true);
$pl->setMotion(new Vector3($x, 1, $z));
$pl->setAllowFlight(false);

It does not work, because it calls setAllowFlight(false); directly after setMotion(); is called and not after the movement is finished.
How can I solve that?

Solved it with setting setAllowFlight(false); on EntityDamageEvent on fall damage.

Yeah, or generally turn it off in the config.
