[SOLVED] Create a sphere of particles.

I guess the title says it all.

PHP:

/** @var Vector3 $center */
$diameter = 10;
$radius = $diameter / 2;
//π = M_PI;


 

Take a look at this: https://forums.pmmp.io/threads/creating-basic-shapes.705/
You should be able to, by decreasing the for loop increase to for example $x += 0.05 instead of $x++, make the particle density bigger which would look better.

 

I had the same thoughts but the loop would consume a heavy amount of time.

 

I finally managed to do it by converting this code I found on Bukkit Forums to PHP. Here's the code for future readers...

PHP:

    /**
    * PMMP should add this to their
    * Position.php
    */
    private static function getDirection($pos) : Vector3
    {
        $y = -sin(deg2rad($pos->pitch));
        $xz = cos(deg2rad($pos->pitch));
        $x = -$xz * sin(deg2rad($pos->yaw));
        $z = $xz * cos(deg2rad($pos->yaw));
        return new Vector3($x, $y, $z);
    }

    private static function genCircle(int $radius, int $vertLines, int $dotsPerLine, $center)
    {
        $pitchDelta = (float)180 / $dotsPerLine;
        $yawDelta = (float)360 / $vertLines;

        $results = [];
        for ($i = 0; $i < $vertLines; ++$i) {
            for ($j = 0; $j < $dotsPerLine; ++$j) {
                $loc = clone($center);
                $loc->yaw = -180 + ($i * $yawDelta);
                $loc->pitch = -90 + ($j * $pitchDelta);
                $v = self::getDirection($loc)->normalize()->multiply($radius);
                $results[] = $v;
            }
        }
        return $results;
    }

    public static function makeSphere($player, $radius = 5) {
        $data = self::genCircle($radius, 20, 20, $player->getLocation());
        foreach ($data as $pos) $player->getLevel()->addParticle(new MobSpellParticle($player->add($pos->x, $pos->y, $pos->z), 255, 255, 255));
    }


PHP:

self::makeSphere($player);
