Is there a way with the api to send block change to a client only (not at server side)

Is there a way with the api to send block change to a client, (but not change the block in the world).
In bukkit i do it with this command : player.sendBlockChange ?

Thx

Yes i know it's deprecated, but i dont know why.
It's usefull for me. That allow me to show to players the limit of their territory wihout modify the wold.

UpdateBlockPacket is public and won't be deprecated or deleted in futur version of the API ?

I will test that... thx

$pk = new UpdateBlockPacket;
$pk->x = $block->x;
$pk->y = $block->y;
$pk->z = $block->z;
$pk->block = $block->getID();
$pk->meta = $block->getMetadata();
$player->dataPacket($pk);

I've done it that way :

private function sendBlockChange(Player $player, Position $position , $blockid) {
$player->dataPacket(MC_UPDATE_BLOCK, array(
"x" => $position->x,
"y" => $position->y,
"z" => $position->z,
"block" => $blockid,
"meta" => 0));
}

UpdateBlockPacket was not known by the plugin.

Same idea long time ago, never started on it (for factions)
