How They Do This? (Help)

Hi, I Got A Question. When I Saw To OwnagePE I Saw The Rainbow Particle Keep Circling The Player Pn The Spawn. Question:
A. How They Got The Rainbow Particles?
B. How The Rainbow Particle Keep Circling?
Thats It!Please Reply.

Here's the full code.
use the Scheduler (RepeatingTask), to keep

PHP:

//PlayerMoveEvent as $sender
$sender = $event->getPlayer();
$level = $sender->getLevel();
$x = $sender->x;
$y = $sender->y;
$z = $sender->z;
$center = new Vector3($x, $y, $z);
$radius = 0.5;
$count = 100;
$particle = new DustParticle($center, mt_rand(), mt_rand(), mt_rand(), mt_rand()); //Color
for($yaw = 0, $y = $center->y; $y < $center->y + 4; $yaw += (M_PI * 2) / 20, $y += 1 / 20){
$x = -sin($yaw) + $center->x;
$z = cos($yaw) + $center->z;
$particle->setComponents($x, $y, $z);
$level->addParticle($particle);


There is the sample video.
If you want to see, please reply me.
But it's japanese

What Is RepeatingTask?Explain It Pls

Seriously you don't know what a repeating task is?!
Go search in the forums

PHP:

public function onJoin(PlayerJoinEvent $event){
$player = $event->getPlayer();
$level = $player->getLevel();
$xpos = $player->getX();
$ypos = $player->getY();
$zpos = $player->getZ();
$c = new Vector3($xpos, $ypos, $zpos);
$sound = new BlazeShootSound($c);
$level->addSound($sound);
$r = mt_rand();
$g = mt_rand();
$b = mt_rand();
$a = 1;
$radius = 0.5;
$count = 250;
$particle = new DustParticle($c, $r, $g, $b, $a);
for($yaw = 0, $y = $c->y; $y < $c->y + 4; $yaw += (M_PI * 2) / 20, $y += 1 / 20){
$x = -sin($yaw) + $c->x;
$z = cos($yaw) + $c->z;
$r = mt_rand();
$g = mt_rand();
$b = mt_rand();
$a = 1;
$particle = new DustParticle($c, $r, $g, $b, $a);
$particle->setComponents($x, $y, $z);
$level->addParticle($particle);
}
}


Why do you construct a particle you are never actually using?

I think he wants it continuously spawning. A repeating task would be better for this.

Understand you probs don't know PHP, but this is common sense.

REPEATING TASK

a TASK that REPEATS


And is this your plugin?
