Solved getDirection with x and z?

How would I know if I should add x or z from getDirection? Or other functions? I am trying to setBlock every air block in front of your face

replace Player:: with the player.
do you mean

PHP:

Player::getLevel()->setBlock(new Vector3(Player::getX()+1, Player::getY()+1, Player::getZ()));

Did you even read my post? x and z is different. What if his x is on his sides?

getDirection returns int 0-3
0 = South(+x)
1 = West(+z)
2 = North(-x)
3 = East(-z)

How would I do it in a blocks perspective? I have a block (dirt) and want to set 2 blocks towards the player looking at it.

Something like this?

PHP:

    $x = $player->x;
    $y = $player->y;
    $z = $player->z;
    switch($player->getDirection()){
        case 0: $x += 2; break;
        case 1: $z += 2; break;
        case 2: $x -= 2; break;
        case 3: $z -= 2; break;
    }
    $level->setBlock(new Vector3($x,$y,$z),Block::get(0));

But I want in a blocks perspective? So I want when a player is looking at a 2 block high pillar, the pillar extends (setBlock) towards the player.

Maybe you mean

PHP:

$x = $player->x;
$y = $player->y;
$z = $player->z;
switch($player->getDirection()){
case 0: $x -= 1; break;
case 1: $z -= 1; break;
case 2: $x += 1; break;
case 3: $z += 1; break;
}
$blocks = $player->getLineOfSight($distance);
foreach($blocks as $b)
$level->setBlock(new Vector3($x,$y,$z),Block::get(1));


What does getLineOfSight do? And $b is useless

It gets the blocks the player is looking at. And returns array of blocks so i just foreach it

Not sure what exactly you are asking about, but maybe you mean these:
