Throw snowball

I know how I can spawn a snowball. But how can I throw it?

PHP:

$pos = $player->getPosition();
        $nbt = new CompoundTag("",[
            new ListTag("Pos",[
                new DoubleTag("",$pos->getX()),
                new DoubleTag("",$pos->getY()+$player->getEyeHeight()),
                new DoubleTag("",$pos->getZ()),
                ]),
            new ListTag("Motion", [
                new DoubleTag("", 2*-sin($player->yaw / 180 * M_PI) * cos($player->pitch / 180 * M_PI)),
                new DoubleTag("", 2*-sin($player->pitch / 180 * M_PI)),
                new DoubleTag("", 2*cos($player->yaw / 180 * M_PI) * cos($player->pitch / 180 * M_PI)),
                ]),
            new ListTag("Rotation", [
                new FloatTag("", lcg_value() * 360),
                new FloatTag("",0),
                ])
            ]);
  $entity = Entity::createEntity('Snowball', $pos->getLevel()->getChunk($pos->getX() >> 4, $pos->getZ() >> 4), $nbt);
        $entity->spawnToAll();

 

How? If I use for example Pig in my code, it works. But I want to throw a snowball

 

And how can I check if it hits the ground? (And get cords)

 

The snowball despawns instantly

PHP:

$nbt = new CompoundTag("",[
            new ListTag("Pos",[
                new DoubleTag("",$pos->getX()),
                new DoubleTag("",$pos->getY()+$player->getEyeHeight()),
                new DoubleTag("",$pos->getZ()),
                ]),
            new ListTag("Motion", [
                new DoubleTag("", 2*-sin($player->yaw / 180 * M_PI) * cos($player->pitch / 180 * M_PI)),
                new DoubleTag("", 2*-sin($player->pitch / 180 * M_PI)),
                new DoubleTag("", 2*cos($player->yaw / 180 * M_PI) * cos($player->pitch / 180 * M_PI)),
                ]),
            new ListTag("Rotation", [
                new FloatTag("", lcg_value() * 360),
                new FloatTag("",0),
                ])
            ]);
  $entity = Entity::createEntity('Snowball', $pos->getLevel()->getChunk($pos->getX() >> 4, $pos->getZ() >> 4), $nbt);
$entity->setMotion($entity->getMotion()->multiply(2));   
        $entity->spawnToAll();

 

entity despawn event?

 

It doesn't throw the snowball. It only spawns and despawns. I want to throw in it

 

use @Thunder33345 method for throwing it
use the EntityDespawnEvent for checking if it despawns

 

Lol look at my code -_-

It isn't working. Or am I using setMotion wrong?

 

I really wonder why ppl still struggle to do this while the code is already written and ready to be adapted. https://github.com/pmmp/PocketMine-MP/blob/master/src/pocketmine/Player.php#L2124-L2160

 

I don't know why, but it isn't working

PHP:

$pos = $player->getPosition();

$aimPos = new Vector3(
      -sin($player->yaw / 180 * M_PI) * cos($player->pitch / 180 * M_PI),
      -sin($player->pitch / 180 * M_PI),
      cos($player->yaw / 180 * M_PI) * cos($player->pitch / 180 * M_PI)
     );
$nbt = new CompoundTag("", [
       "Pos" => new ListTag("Pos", [
        new DoubleTag("", $pos->x),
        new DoubleTag("", $pos->y + $player->getEyeHeight()),
        new DoubleTag("", $pos->z)
       ]),
       "Motion" => new ListTag("Motion", [
        new DoubleTag("", $aimPos->x),
        new DoubleTag("", $aimPos->y),
        new DoubleTag("", $aimPos->z)
       ]),
       "Rotation" => new ListTag("Rotation", [
        new FloatTag("", $player->yaw),
        new FloatTag("", $player->pitch)
       ]),
      ]);
      $f = 1.5;
      $snowball = Entity::createEntity("Snowball", $pos->getLevel()->getChunk($pos->getX() >> 4, $pos->getZ() >> 4), $nbt);
      $snowball->setMotion($snowball->getMotion()->multiply($f));
        $snowball->spawnToAll();


 

WTF? $pos->getLevel()->getChunk($pos->getX() >> 4, $pos->getZ() >> 4) is that anywhere in the code i showed you? no. and there is a reason for that https://github.com/pmmp/PocketMine-MP/commit/c21197ef176166b1c2c19b091cf84664aa878c00

 

What would be correct?

This isn't working:

PHP:

$snowball = Entity::createEntity("Snowball", $player->getLevel(), $nbt, $player);

 

Oh I had an old version. Now it works! And how can I check the cord where the snowball despawns?

 

On EntityDespawnEvent, get the Entity, check if it is an instance of Snowball, then get the position of it.
