Hey guys,

 

So I have what is essentially a custom snowball.  I would like it to create particles when it flies.  I looked in the bow class, and it uses the function onUpdate() to create the particles if the arrow is a critical hit.  However, when I try using this function in the snowball class, the snowball renders, the particles render properly, but the snowball never moves.  Anyone know how to fix this?

Does anybody know?  I really need this for my mod.

Can you post the code for your snowball class?

Here it is.  I have the onUpdate commented out though.

    public EntityBombProjectile(World par1World)
    {
        super(par1World);
    }

    public EntityBombProjectile(World par1World, EntityLiving par2EntityLiving)
    {
        super(par1World, par2EntityLiving);
    }

    public EntityBombProjectile(World par1World, double par2, double par4, double par6)
    {
        super(par1World, par2, par4, par6);
    }

        {
            byte b0 = 99;

            if (par1MovingObjectPosition.entityHit instanceof EntityBlaze)
            {
                b0 = 3;
            }

            par1MovingObjectPosition.entityHit.attackEntityFrom(DamageSource.causeThrownDamage(this, this.getThrower()), b0);
        }

        for (int i = 0; i < 8; ++i)
        {
            this.worldObj.spawnParticle("snowballpoof", this.posX, this.posY, this.posZ, 0.0D, 0.0D, 0.0D);
        }

        if (!this.worldObj.isRemote)
        {
            this.setDead();
        }
    }
    
/*    public void onUpdate() {

    /**

    public void writeEntityToNBT(NBTTagCompound par1NBTTagCompound)
    {
        super.writeEntityToNBT(par1NBTTagCompound);
        par1NBTTagCompound.setInteger("ExplosionPower", this.field_92057_e);
    }

    /**

     */
    public void readEntityFromNBT(NBTTagCompound par1NBTTagCompound)
    {
        super.readEntityFromNBT(par1NBTTagCompound);

        if (par1NBTTagCompound.hasKey("ExplosionPower"))
        {
            this.field_92057_e = par1NBTTagCompound.getInteger("ExplosionPower");
        }
    }
}

 

 

Try putting super.onUpdate() in your update method, so that it runs the EntityThrowable update code, which contains the code to make it move.
