Spawning particles around player

Hey,

so for one of the features in my plugin there will be an item that spawns with particles that spawn around it. For now, I am trying to get the particles to spawn around player in a 'circle' type, whereas whenever I attempt to do it then it always goes bit off a circle shape, and I no longer am in the middle of it.



I've attempted multiple ways of going against this problem, this is the latest code I've used:

Code:java

 Location l = p.getLocation();
 
//loop to make a circle of fire
for (double t = 0; t < 2 * Math.PI; t += 0.39) {
p.getWorld().playEffect(l.add(1 * Math.cos(t), 0, 1 * Math.sin(t)), Effect.SMOKE, 4);
}

EDIT
I've attempted to use this method now, but still failed as I can't get it to spawn all locations in a circle but only on one spot.
