I made an entity which should fall from the sky. It falls, but the hitbox seems to lag behind the actual entity. And when the hitbox is out of the View Frustum it doesn't render, thus creating a bug which I must remove.

 

Registering the entity: 

ENTITY_COMET = EntityEntryBuilder.create().entity(EntityComet.class).id(InterstellarComets.MODID + ":" + "comet", 0).name("comet").tracker(64, 20, true).build();

 

Entity's onUpdate code:

@Override
public void onUpdate() {
	super.onUpdate();
	this.prevPosX = this.posX;
	this.prevPosY = this.posY;
	this.prevPosZ = this.posZ;
		
	this.posX += this.motionX;
	this.posY += this.motionY;
	this.posZ += this.motionZ;

	if (this.posY <= 68) { //that it doesn't fall out of the map
		this.posY = 68;
	}else{
		this.motionY -= getGravityVelocity();
	}
}

protected float getGravityVelocity() {
	return 0.03F;
}

What update frequency do living entities use? they seem to fall correctly.
