ParticleNativeAPI [1.7+]

I've made 3 tests on localhost (MC 1.14.3) to measure execution time of 100 000 particles in random locations around my character.

All tests were made after an extensive warmup of executing them several times to allow JVM to optimize frequently used code.

All code used to test is found on my repository here.

Tests consist of 4 methods to send particle:

• Version specific – uses directly NMS and OBC to send packet,
• ParticleNativeAPI – uses this api to send particle with simple method,
• SpigotAPI – uses Spigot API's spawnParticle method (to player) to send effect,
• Reflection – uses NMS and OBC reflected classes (with accessibility set to true) to send particle. Those classes/methods/fields are cached for multiple use.

As you can see, at least on my machine, ParticleNativeAPI is even faster than Spigot API and very close in speed to version specific implementation.

public class PluginName extends JavaPlugin {

   // cache particles list for later use
   private Particles_1_8 particles;

   @Override
   public void onEnable() {
       // check if everything is fine
       if (!ParticleNativePlugin.isValid()) {
           getLogger().log(Level.SEVERE, "Error occurred while loading dependency.");
           this.setEnabled(false);
           return;
       }
       
       // get API
       ParticleNativeAPI api = ParticleNativePlugin.getAPI();

       // choose particles lists you want to use
       particles = api.getParticles_1_8();
   }

   // example usage
   @Override
   public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
       if (!command.getName().equalsIgnoreCase("somecmd")) return true;

       if (!(sender instanceof Player)) {
           sender.sendMessage(ChatColor.RED + "You must be player to use this command!");
           return true;
       }

       Player pSender = (Player) sender;
       Location loc = pSender.getLocation();

       // create a particle packet
       Object packet = particles.FLAME().packet(true, loc);

       // send this packet to all players within 30 blocks
       particles.sendPacket(loc, 30D, packet);

       return true;
   }
}
