Circle

Works! :3 thank you)

And, last question, if you do not mind)
Not sure how to remove all particles of a player?
ie instant removal

Depends on your particle. I don't think it is possible for most particles except FloatingTextParticle.

I'm talking specifically about FloatingTextParticle

PHP:

$particle->setInvisible();
$level->addParticle($particle);

okay, thanks :3

Why would you want to spawn FT like that?

Actually I'm Russian, but Google translator says that you ask why I want to throw eggs xD

LMAO...lol XDXDXD

I again about these particles
Is it possible to change the radius?

Yep. Just multiply $x and $z.

ok, thanks)

Oh, and don't know how to make a simple circle? (as in a spiral, but just around the player)

Use the code for a sphere in the previous page but keep the Y axis at the same place, and delete the randomization.

okay, thanks

I seem invalid, because did not understand how to extend the spiral..

PHP:

    public function spiral() {
        $level = $this->getServer()->getDefaultLevel();
        $x = 128.5;
        $y = 66.8;
        $z = 128.5;
        $center = new Vector3($x, $y, $z);
        $radius = 5;
        $count = 100;
        $particle = new PortalParticle($center);
        for($yaw = 3, $y = $center->y; $y < $center->y + 4; $yaw += (M_PI * 2) / 30, $y += 1 / 25){
            $x = -sin($yaw) + $center->x;
            $z = cos($yaw) + $center->z;
            $particle->setComponents($x, $y, $z);
            $level->addParticle($particle);
        }
    }

Oh. Then, modify my spiral code. Stop modifying Y. Instead, make an increasing radius.

Translation please?

okay, waiting, please)
