how to drop item (developper here is a non corrected bug ^^)

if(!world.isRemote){
        EntityItem var14 = new EntityItem(world,(double)(i),(double)(j+1),(double)(k),new ItemStack(*name_of_the_mod*.block, *number_of_item* , 0));
    var14.delayBeforeCanPickup = 10;
    world.spawnEntityInWorld(var14);
}
