Unable to place spawner.

What could be a possible reason my spawner can't place?

My place() function.

PHP:

public function place(Item $item, Block $blockReplace, Block $blockClicked, int $face, Vector3 $clickVector, Player $player = null): bool {
    parent::place($item, $blockReplace, $blockClicked, $face, $clickVector, $player);
    if($item->getDamage() > 9 and $item instanceof CustomItem) {
        /** @var CompoundTag $tag */
        $tag = $item->getNamedTagEntry(CustomItem::SPECIAL);
        $tier = $tag->getInt("tier");
        $this->setTier($tier);
        $tile = $this->getLevel()->getTile($this);
        $this->entityId = $item->getDamage();
        if(!$tile instanceof MobSpawner) {
            /** @var CompoundTag $nbt */
            $nbt = new CompoundTag("", [
                new StringTag(Tile::TAG_ID, Tile::MOB_SPAWNER),
                new IntTag(Tile::TAG_X, (int)$this->x),
                new IntTag(Tile::TAG_Y, (int)$this->y),
                new IntTag(Tile::TAG_Z, (int)$this->z),
                new IntTag(MobSpawner::TAG_ENTITY_ID, $this->entityId),
                new IntTag(MobSpawner::TAG_SPAWN_COUNT, 4),
                new IntTag(MobSpawner::TAG_MIN_SPAWN_DELAY, floor(200 / $tier)),
                new IntTag(MobSpawner::TAG_MAX_SPAWN_DELAY, floor(800 / $tier))
            ]);
            /** @var MobSpawner $tile */
            $tile = Tile::createTile(Tile::MOB_SPAWNER, $this->getLevel(), $nbt);
            $tile->setEntityId($this->entityId);
            return true;
        }
    }
    return true;
}


 

Does it ever leave your hand? Does it appear for a split second, then go back to your hand?

 

2nd one

 

Can I see where you registered the block? I assume it's a class that overrides the existing MonsterSpawner class, right?

 

Its registered already.

 

Send your MobSpawner::addAdditionalSpawnData()
method.

 

PHP:

protected function addAdditionalSpawnData(CompoundTag $nbt): void {
    $nbt->setInt(self::TAG_ENTITY_ID, $this->getSpawnCompound()->getInt(self::TAG_ENTITY_ID));
    $nbt->setInt(self::TAG_DELAY, $this->getSpawnCompound()->getInt(self::TAG_DELAY));
    $nbt->setInt(self::TAG_SPAWN_COUNT, $this->getSpawnCompound()->getInt(self::TAG_SPAWN_COUNT));
    $nbt->setInt(self::TAG_SPAWN_RANGE, $this->getSpawnCompound()->getInt(self::TAG_SPAWN_RANGE));
    $nbt->setInt(self::TAG_MIN_SPAWN_DELAY, $this->getSpawnCompound()->getInt(self::TAG_MIN_SPAWN_DELAY));
    $nbt->setInt(self::TAG_MAX_SPAWN_DELAY, $this->getSpawnCompound()->getInt(self::TAG_MAX_SPAWN_DELAY));
}
