MurderMystery

I'm creating a MurderMystery plugin from 0%, I'm 98% finished, but I need a command to get to a coordinate (it's an example), that tells you the steps you must do to get there.
Can someone give me an example of how to do it?

 

PHP:

public function getPositionSteps(Player $player, Position $position) : int {
            $playerPosition = $player->getPosition();
          
            $playerX = round($playerPosition->getX());
          
            $playerZ = round($playerPosition->getZ());
          
            $positionX = round($position->getX());
          
            $positionZ = round($position->getZ());
          
            $steps = $playerX - $positionX;
          
            $steps = abs($steps + $playerZ - $positionZ);
          
            return $steps;
        }
