create particles around a Block

I want to create a plugin which adds particles around a block.

for example the player executes /blockparticles add

a message is sent to the player saying the next block they touch will have particles around it.

how can I create the particle bit?

 

i am asking how to create the particles around the block though xd

 

PHP:

$bx = floor($block->x) > 0 ? floor($block->x) + 0.5 : floor($block->x) - 0.5; //Blocks x, y and z already come floored :P
$bz = floor($block->z > 0) ? floor($block->z + 0.5) : floor($block->z - 0.5);
for($y = floor($block->y);$y <= floor($block->y) + 1;$y += 0.1){
  for($x = $bx - 0.5;$x < $bx + 0.5;$x += 0.1){
    $block->getLevel()->addParticle(new FlameParticle(new Vector3($x, $y, $bz + 0.5)), $this->getServer()->getOnlinePlayers());
    $block->getLevel()->addParticle(new FlameParticle(new Vector3($x, $y, $bz - 0.5)), $this->getServer()->getOnlinePlayers());
  }
  for($z = $bz - 0.5;$z < $bz + 0.5;$z += 0.1){
    $block->getLevel()->addParticle(new FlameParticle(new Vector3($bx + 0.5, $y, $z)), $this->getServer()->getOnlinePlayers());
    $block->getLevel()->addParticle(new FlameParticle(new Vector3($bx - 0.5, $y, $z)), $this->getServer()->getOnlinePlayers());
  }
  if($y === floor($block->y) or $y === floor($block->y) + 1){
    for($x = $bx - 0.5;$x < $bx + 0.5;$x += 0.1){
      for($z = $bz - 0.5;$z < $bz + 0.5;$z += 0.1){
        $block->getLevel()->addParticle(new FlameParticle(new Vector3($x, $y, $z)), $this->getServer()->getOnlinePlayers());
      }
    }
  }
}


Its a bad and kinda slow code, i know
Dont use this code if you dont have to
(it may also lagg the client is he has bad phone)

 

PS: if you are using a task, set it to at least 20 ticks

 

Why is a task needed for this? Does the task make the particles repeat themselves?

thankyou for the code though !

 

Unless you want the particles to despawn quickly, you can use a task to make them respawn as needed.

 

Ahh. Thanks. However he put in his code new FlameParticle.. so does this mean I have to create a class with the flame particle ?
if so , how

 

No, pocketmine\level\particle\FlameParticle is an existing class in PocketMine. You never specified what type of particle you wanted to spawn around the block.

 

ok. I can only spawn particles implemented in PMMP anyway, right?

 

You could add particles unimplemented in PMMP with a LevelEventPacket, but I suggest sticking with those that extend GenericParticle.
