Create fake block

How to create a fake block? A visible block that is fake not an entity block.

https://github.com/PocketMine/PocketMine-MP/blob/master/src/pocketmine/level/Level.php#L824

But can I make it float? I'm trying to make a floating fake block that follows players.

If you want it to float and move fluently, it has to be an entity block (falling block).

OK, I will try.

Edit: Where is the falling block in PocketMine src?

https://github.com/PocketMine/PocketMine-MP/blob/master/src/pocketmine/entity/FallingSand.php

xD I don't know how to add it, can you give me an example?

https://github.com/PocketMine/PocketMine-MP/blob/master/src/pocketmine/entity/Entity.php#L415
Level::createEntity("FallingSand",$chunk,$nbt);

You talk about a block like in Hide'n'Seek, right? There are plenty of toppics in this forum, search for hide and seek

No. I wan't a block that floats and moves in the air, not moves on the floor.

I would suggest looking in the code for Slapper; spawn a FallingSand entity with a custom block ID, and the tag NoAI (to make it float)

Then.. Change the coordinates?! xD

this works but now it sets the block instead of following the player.

PHP:

public function onMove(PlayerMoveEvent $e){
        $p = $e->getPlayer();
        $fall = Entity::createEntity("FallingSand", $p->getLevel()->getChunk($p->x >> 4, $p->z >> 4), new Compound("", [
            "Pos" => new Enum("Pos", [
                new Double("", $p->x + 0.5),
                new Double("", $p->y+1),
                new Double("", $p->z + 0.5)
            ]),
            "Motion" => new Enum("Motion", [
                new Double("", 0),
                new Double("", 0),
                new Double("", 0)
            ]),
            "Rotation" => new Enum("Rotation", [
                new Float("", 0),
                new Float("", 0)
            ]),
            "TileID" => new Int("TileID", 57),
            "Data" => new Byte("Data", 0),
        ]));
        $fall->spawnToAll();
    }

You have to use packets.

Sorry. I mean: You have to kill the entity after some seconds (the packet) or update its coordinates instead of spawning a new one

You should spawn the FallingSand first for once (in events like PlayerJoinEvent), then store the FallingSand entityId in an array(for me i use player name as key). Then when player moves, get the FallingSand entity from the stored entityId and setPosition of the FallingSand to the player's position
Like so

PHP:

$this->blocks[$player->getName()] = $fallingsand->getId();//just after spawning

        public function onPlayerMove(PlayerMoveEvent $e){
            $p = $e->getPlayer();
            $n = $p->getName();
            if (!isset($this->blocks[$n])) return;
            $block = $p->getLevel()->getEntity($this->blocks[$n]);
            if ($block) $block->setPosition($p->getPosition()->add(0,0.2,0));
        }
