[1.7.10]Particle Entities not moving when spawned

[ArtisanGaming]

Hello again,

 

So I am having a throwable entity spawn some particles on impact, but when the particles spawn they all just spawn in one place and then stay there (rather than spawning in one place and then moving outwards.  How would I remedy this?

 

Here is my spawning code:

 

public void spawnParticles(String type, int number) {
for (int l = 0; l < number; ++l){
	double motionX = rand.nextGaussian() * 0.02D;
	double motionY = rand.nextGaussian() * 0.02D;
	double motionZ = rand.nextGaussian() * 0.02D;
	this.worldObj.spawnParticle(type, this.posX, this.posY, this.posZ, motionX, motionY, motionZ);
        }
}
