Problem with RIGHT_CLICK_BLOCK

Hello everyone.
I want to add func when player uses certain item and after column of blocks appears with height equal 6, but RIGHT_CLICK_BLOCK called twice and set 7-height pillar and also removed 2 items instead of 1.
I don't register event twice and I tried check main hand

Code presents below

Code:

@EventHandler
    public void onItemUse(PlayerInteractEvent e) {
        if (e.getAction().equals(Action.RIGHT_CLICK_BLOCK)) {
            if(EquipmentSlot.HAND.equals(e.getHand()) && flag_basic.targetItem.isSimilar(e.getItem())) {
                Location basicOrigin = e.getClickedBlock().getLocation();
                e.getItem().setAmount(e.getItem().getAmount() - 1);

                for (int iB = 0; iB < 6; iB++) {
                    basicOrigin.add(0, 1, 0);

                    Bukkit.getServer().getWorld(e.getPlayer().getWorld().getName()).getBlockAt(basicOrigin).setType(Material.OAK_LOG);

                }
            }
        }
    }

 

Try this code, it worked for me.
Tested in 1.7.10 version.

Use "==" instead of .equals() to compare Enums.

Code:

@EventHandler
public void onItemUse(PlayerInteractEvent e)
{
    if(e.getItem().getType() == Material.STICK && e.getAction() == Action.RIGHT_CLICK_BLOCK)
    {
        Block b = e.getClickedBlock();
        e.getItem().setAmount(e.getItem().getAmount() - 1);
       
        for(int iB = 1; iB <= 6; iB++)
        {
            b.getRelative(BlockFace.UP, iB).setType(Material.LOG);
        }
    }
}

 

If it runs twice you might be registering the pluginmanager registerevents function twice. Check in your onEnable() that that isn't true.
