I made a particle effect of my own, and I can only display the particle effect in the game through the command : /particle mymod:juan1particle 0 0 0 0 0 255 100 3.   When I want add the particle through World.addParticle(IParticleData particleData, double x, double y, double z, double xSpeed, double ySpeed, double zSpeed), it does not show at all.   But when I change the particleData Parameter from my particledata's instance to those in the ParticleTypes in the vanilla, It works without problem. So it seems that only my particle effect can't be added into the game, but those in the vanilla can be added.

This is where I want to call the addParticle() method, it is in the livingTick() in an entity. But it shows no particle effect.

@Override

public void livingTick() {

double x = rand.nextGaussian() * 0.02D;

double y = rand.nextGaussian() * 0.02D;

double z = rand.nextGaussian() * 0.02D;

double px = this.getPosX() + 4.0D * rand.nextDouble() - 2.0D;

double py = this.getPosY() + rand.nextDouble() - 0.5D;

double pz = this.getPosZ() + 4.0D * rand.nextDouble() - 2.0D;

world.addParticle(new Juan1ParticalData(new Vector3d(x, y, z), new Color(0xae6be2), 0), px, py, pz, x, y, z);

 }

When I change "new Juan1ParticalData(new Vector3d(x, y, z), new Color(0xae6be2), 0)" to "ParticleTypes.DRAGON_BREATH" , the particle effects appeared.

These are my particle effect classes, they are all copied from a tutorial.

return particle;

}

}

I wander how to use World.addParticle to add custom particle effect, or is there any other ways to add? Or is there anything wrong with my particle effect?
