Why this ain't working?

PHP:

// This is looped 20 times per second wile $this->lastRadius is equal to $this->radius (100)
$r = $this->lastRadius;
$pitch = $this->angle[0];
$yaw = $this->angle[1];

$x = -sin($yaw / 180 * M_PI) * cos($pitch / 180 * M_PI) * $r;
$y = -sin($pitch / 180 * M_PI) * $r;
$z = cos($yaw / 180 * M_PI) * cos($pitch / 180 * M_PI) * $r;

echo 'X: '.$x."\n";
echo 'Y: '.$y."\n";
echo 'Z: '.$z."\n";
echo 'Radius:'.$r."\n";
echo 'Pitch: '.$pitch."\n";
echo 'Yaw: '.$yaw."\n";
echo "______";
$particle = new DustParticle($this->pos->add($x, $y, $z), $this->color[0], $this->color[1], $this->color[2]);
$this->pos->level->addParticle($particle);

$r++;
$this->lastRadius = $r;


But the rocket (particles) are launched chaotic

Hay how to add particles Block Bedrock ?

3 - 4 Line from bottom.

# Bump

what do you mean by launched chaotic?

No metter how i'm facing it will launch "rocket" somewhere else.

Do you understand trigonometry?

Yes else i would'nt be posting this thread.
