playEffect() on player not showing up

I'm making a plugin that will create mob spawner flames around every player online with this code:

Code:java

public void onEnabled(){
        getServer().getScheduler().scheduleSyncRepeatingTask(this, new Runnable(){
 
            @Override
            public void run() {
                for (Player p : getServer().getOnlinePlayers()){
                    p.getWorld().playEffect(p.getLocation(), Effect.MOBSPAWNER_FLAMES, 30);
                }
            }
 
        }, 0, 20);
    }

However, when I put the plugin on my private server for testing, I don't see any flames.

Do you see it in third person view?

getLocation() doesn't give you the center of the player, you need to position on to player's body or so.

 

Try:

Code:java

getServer().getScheduler().scheduleAsyncRepeatingTask(this,
new Runnable(){
@Override
public void run(){
for(Player p : Bukkit.getServer().getOnlinePlayers()){
p.getWorld().playEffect(p.getLocation(), Effect.MOBSPAWNER_FLAMES, 10);
}
}
}, 20, 20);

 

Yeah getLocation gives you the leg position.
What's the 30 for?

 

tommycake50 - It's a data value. To be honest, I'm really not sure what it does, I saw it in example code on one of my other threads.

newboyhun - I double checked to make sure that particles are on, and I can't see it in third person view.

All you did that I saw was make it async, which would just add more possible errors...

 

the data value changes the direction of the smoke particle. I believe there are only 9 directions starting at 0. So try a data value <= 8

 

Changing the data value didn't change that fact that I couldn't see any particles on the player at all.

 

I think it is the amount

 

But, that wouldn't make sense, because regardless of the data value given, I can't see any particles from playEffect().

 

Try p.playEffect()

It shouldn't be any different, but I've seen weirder things with Bukkit. Also if you were interested in more particle effects: https://github.com/OvercastNetwork/SportBukkit

 

Wow! Player.playEffect() works! My only concern is that p.playEffect() only plays the effect for that specific player, and for the purposes of my plugin, that won't work.

Edit: Doing Effect.MOBSPAWNER_FIRE doesn't work. I'm think that it's maybe an issue with the loop I'm using, because the playEffect() method works outside of it. Another Edit: I started the loop in the onEnabled() method. onEnabled() should've been onEnable(). onEnabled() never was run because it was meant to be onEnable().

 

JaguarBolt mobspawner fire is an "oldest" effect and it works fine. I used this effect in some of my plugins including the NoSmoking! and PlayEffect. Here is example: https://github.com/fromgate/PlayEff...e/fromgate/playeffect/effect/EffectFlame.java

May be you trying to use wrong name? Right name is Effect.MOBSPAWNER_FLAMES
The data value for this effect does not mean anything. So you can type world.playEffect(loc,Effect.MOBSPAWNER_FLAMES, 0) and it will work. Data is required for SMOKE effect (Example: https://github.com/fromgate/PlayEff...e/fromgate/playeffect/effect/EffectSmoke.java) and for some other effects.

I think you need to do additional check before play effect in by loop. You must be sure that there's a player can see this effect and play this effect. If no one can see this effect - you don't need to play it. If you play a lot of effects you can overload a network bandwidth (every playEffect sends a packet to players).
