Spawn item entity and check when it touches ground or another entity.

Hello dear friends))) , I have two problems
1:I tried to spawn item Entity using this code , but it not works;
2:I want to check when Item entity from this code touches ground or another entity(like player);
Is this possible?
Thx for your answers))

PHP:

$speed = 0.8;
        $pos = $player->getPosition();
        $dir = $player->getDirectionVector();
        $frontPos = $player->add($player->getDirectionVector()->multiply(1));
        $dir->x = $dir->x * $speed;
        $dir->y = $dir->y * $speed;
        $dir->z = $dir->z * $speed;
        $nbt =
            new Compound("",
                         ["Pos" => new Enum("Pos",
                            [new Double("", $frontPos->x),
                                new Double("", $frontPos->y+1),
                                new Double("", $frontPos->z)]),
                            "Motion" => new Enum("Motion",
                            [new Double("",$dir->x),
                                new Double("",$dir->y),
                                new Double("",$dir->z)]),
                          "Rotation" => new Enum("Rotation",
                            [new Float("", 0),
                                new Float("", 0)])]);
        Entity::createEntity(Item(1), $pos->getLevel()->getChunk($pos->x >> 4, $pos->z >> 4),$nbt)->spawnTo($playrs);


What is Item(1)? Learn PHP.

i know php -_- i just tried to spawn Item ENTITY not item packet or something else!

If you don't have the answer don't type "Learn php" please

On collide with entity, run this is a task etc.

PHP:

foreach($itemEntity->getLevel()->getNearbyEntities($itemEntity->boundingBox->grow(0.5, 0.5, 0.5), $itemEntity) as $e){
           //$e is the entity it collided with
        }


If on ground

PHP:

$onGround = count($itemEntity->getLevel()->getCollisionBlocks($itemEntity->boundingBox->grow(0.5, 0.5, 0.5)>offset(0, -0.1, 0))) > 0;

PHP:

Entity::createEntity("Item", $p->chunk,$nbt)->spawnToAll();

thanks but can you correct my code so i can spawn item entity

You should be able to figure out where it goes if you know php... JUST SAYING

and another question: how do i match Item entity that i spawned as $itemEntity???

i understand where it goes i just can't spawn item entity something wrong with Item

here is the problem part of the code

PHP:

Entity::createEntity(Item(1), $pos->getLevel()->getChunk($pos->x >> 4, $pos->z >> 4),$nbt)->spawnTo($playrs);


i use pocketmine/entity/Item.php

PHP:

Entity::createEntity("Item", $player->chunk,$nbt)->spawnToAll();

Can you put all you want to say in one post? You are spamming the thread

It isnt Item(1), what does Item(1) mean? It should be Item::get(1,0,1)

You also misspelled players.

Obviously, something is VERY weird, isn't it? The variable names, and the order they are defined is EXACTLY the same.
Also:

PHP:

$dir = $player->getDirectionVector();
$frontPos = $player->add($player->getDirectionVector()->multiply(1));


If you actually have written the code yourself, most people would have done:

PHP:

$frontPos = $player->add($dir->multiply(1));


If you don't know how to use it, don't copy it. You clearly don't know.
Edit: I have deleted that post so that this does not occur again. Moderators can still see the deleted posts, so let's leave it to them. I still have the code, so it wouldn't really matter, either.

Actually it should be "Item"

this is my problem...
i wanna spawn item and give it parameters such as id or damage , but when i try to do that i am getting a crash because its an entity....

Can you tell me what this is for?

PHP:

       $frontPos = $player->add($player->getDirectionVector()->multiply(1));


What do you want to do to the entity?
Take a look at how Level::dropItem() spawns the item entity
https://github.com/PocketMine/PocketMine-MP/blob/master/src/pocketmine/level/Level.php#L1463

i know its silly to leave it in my code
it was no 1 it was 1,5 or something like that, i used this code in my other plugin...

That's very funny, I also had 1.5 too.
