so i want to make it so when i right click mossycobble(vanilla block) by my custom item it changes to cobble and drops another custom item, i know i have to use onItemUse but i am new to java.

Thnx in advance

ohh yeah figured it out

    @Override
    public ActionResultType onItemUse(ItemUseContext context) {
    
        
        World world = context.getWorld();
        BlockPos pos = context.getPos();
        PlayerEntity playerIn = context.getPlayer();
        ItemStack item = context.getItem();
        Hand handIn = context.getHand();

        if (!world.isRemote && world.getBlockState(pos).getBlock() == Blocks.MOSSY_COBBLESTONE)
        {
        (( ServerWorld)world).setBlockState(pos, Blocks.COBBLESTONE.getDefaultState());
        item.damageItem(1, playerIn, (entity) -> {entity.sendBreakAnimation(handIn);;});
        playerIn.inventory.addItemStackToInventory(new ItemStack(ItemInit.moss));
        }
        
        return super.onItemUse(context);
    }
