Solved Particle Effects

Hello there
I've reached the end of my wits for this one...

Code:

   
    @EventHandler
    public void onShift(PlayerToggleSneakEvent e)
    {
        Location loc = e.getPlayer().getLocation().add(0,2,0);
        ParticleEffect.HEART.display(0,0,0,0,1,loc,20);
    }

Basically, it won't show any particles effect at all. There are no errors, no exceptions, nothing. And that is why I can't find anything wrong with it. I got the Particle Library from here:
https://github.com/DarkBlade12/ParticleEffect
And the parameters above the "display" function are (offsetX, offsetY, offsetZ, speed, amount, center, range), according to Eclipse that is.
I'm probably just dumb, and overlooking something very small probably, but I can't find it no matter how hard I try. Plz help.

 

Yes, I did.
I'm using CraftBukkit 1.9.4 by the way

EDIT: I'm so stupid (I said so didn't I) I had Particles on minimal; sorry for wasting your time
