Check player position

How can I check if a players walks through two block? And if the player walks around these blocks he should get a message

 

Through two blocks? As in moves by two blocks??

 

There is a wall with some empty blocks. I want to check if the players walks though the empty blocks. And if he walks around it, he gets a message

 

Okay, I'm not sure what I am visualizing is right. It would be nice if you can provide an image of what you are meaning.

 

This

 

I swear to god that I don't know how to attach images here

 

No.. I want to do it over the hole world.

 

I want to make it like an invisible wall along the whole world were the passage is.

 

The players should only fly through this ring:

 

But how can I send a message when the player fly's around it? Can I check this?

 

I tried this to check if the block on the players right is stone. (Didn't work)

PHP:

$yaw = $player->yaw;
$right = $yaw + 180;
$x = cos($right * M_PI / 180) * 1 + $player->x;
$z = sin($right * M_PI / 180) * 1 + $player->z;
if($player->getLevel()->getBlock($player->subtract($x,0,0))->getID() === 1) {

 

I use this to check if player is in the area

PHP:

#$pp is player position, $p1 is first point, $p2 is second point
    public function isInside(Vector3 $pp, Vector3 $p1, Vector3 $p2){
       return ((min($p1->getX(),$p2->getX()) <= $pp->getX()) &&
               (max($p1->getX(),$p2->getX()) >= $pp->getX()) &&
               (min($p1->getY(),$p2->getY()) <= $pp->getY()) &&
               (max($p1->getY(),$p2->getY()) >= $pp->getY()) &&
               (min($p1->getZ(),$p2->getZ()) <= $pp->getZ()) &&
               (max($p1->getZ(),$p2->getZ()) >= $pp->getZ()));
   }


 

But I want to check the block on the players right

 

Does someone know how to check if the right and the left block of a player is stone?

 

Use $this->getLevel()->getBlock() and the Position left or right of the player

 

But my question was how to get left and right...

 

Get the facing direction and then depending on that x or y + and - 1 maybe?

 

I tried this:
But it isn't working correctly

PHP:

foreach($nrs as $nr) {
        if($player->getLevel()->getBlock($player->subtract(0,$nr,0))->getID() == 1 && $player->getLevel()->getBlock($player->subtract(0,-$nr,0))->getID() == 1) {
        $player->sendPopup(TextFormat::GREEN . "You are in a stone room");
}

$nrs ist an Array with the numbers 1 to 10

 

Most likely both conditions cannot be satisfied at the same time so try using or instead of &&

 

I tried this. But it's only true, if the player is in the middle of it. Do u know why?

PHP:

$in = 0;
if($player->getLevel()->getBlock(new Vector3($x, $y + $nr, $z))->getId() == 159) {
$in++;
}
if($player->getLevel()->getBlock(new Vector3($x, $y - $nr, $z))->getId() == 159) {
$in++;
}
if($in == 2) {
$player->sendMessage("§aTRUE");
} elseif($in == 1) {
$player->sendMessage("§cFALSE");
}
}
