code chest

Can you tell the code to make the chest
like virtual chest
Example:
If we write the command / test. he would open a chest containing tnt

 

PHP:

    public function sendChestShop(Player $player){
        $nbt = new CompoundTag('', [
            new ListTag('Items', []),
            new StringTag('id', Tile::CHEST),
            new IntTag('x', floor($player->x)),
            new IntTag('y', floor($player->y)),
            new IntTag('z', floor($player->z))
        ]);
        /** @var Chest $tile */
        $tile = Tile::createTile('Chest', $player->chunk, $nbt);
        $block = Block::get(Block::CHEST);
        $block->x = floor($tile->x);
        $block->y = floor($tile->y);
        $block->z = floor($tile->z);
        $block->level = $tile->getLevel();
        $block->level->sendBlocks([$player], [$block]);
        $inventory = $tile->getInventory();
        $inventory->setContents(array_fill(0, 27, Item::get(Item::TNT)));
        //$inventory->addItem(Item::get(Item::TNT)):
        $player->addWindow($inventory);
    }


 

With this code, how to make sure that the player can't add anything inside?

 

You need to use InventoryTransactionEvent for that, and also, add an NBT tag to the tile for identification.

PHP:

public function sendChestShop(Player $player){
        $nbt = new CompoundTag('', [
            new ListTag('Items', []),
            new StringTag('id', Tile::CHEST),
            new IntTag('x', floor($player->x)),
            new IntTag('y', floor($player->y)),
            new IntTag('z', floor($player->z))
        ]);
        /** @var Chest $tile */
        $tile = Tile::createTile('Chest', $player->chunk, $nbt);
        $tile->namedtag->blocktrans = new IntTag('blocktrans', 1);
        $block = Block::get(Block::CHEST);
        $block->x = floor($tile->x);
        $block->y = floor($tile->y);
        $block->z = floor($tile->z);
        $block->level = $tile->getLevel();
        $block->level->sendBlocks([$player], [$block]);
        $inventory = $tile->getInventory();
        $inventory->setContents(array_fill(0, 27, Item::get(Item::TNT)));
        //$inventory->addItem(Item::get(Item::TNT)):
        $player->addWindow($inventory);
    }


PHP:

    public function onTransaction(InventoryTransactionEvent $event){
        $transactions = $event->getTransaction()->getTransactions();
        $player = null;
        $chestinv = null;
        $action = null;
        foreach($transactions as $transaction){
            if(($inv = $transaction->getInventory()) instanceof ChestInventory && isset($inv->getHolder()->namedtag->blocktrans)){
                //This means $inv is a custom inventory..
                $event->setCancelled();
                break;
            }
        }
