Solved Right click block nullpointer error

Hello guys,

I got a nullpointer exception when I right click on a block with nothing in my hand..
My code is:

Code:java

if(e.getAction() == Action.RIGHT_CLICK_BLOCK ){
            if(player.getItemInHand() == null) {
 
            }
            else if(!player.getItemInHand().getItemMeta().getDisplayName().contains(ChatColor.GOLD + "Hub") && !player.getItemInHand().getItemMeta().getDisplayName().contains(ChatColor.GOLD + "Kit Selector") && !player.getItemInHand().getItemMeta().getDisplayName().contains(ChatColor.RED + "Apple of health")){
 
            }
            else if(player.getItemInHand().getItemMeta().getDisplayName().equalsIgnoreCase(ChatColor.GOLD + "Hub")){
              if(block.getType() == Material.SIGN_POST || block.getType() == Material.WALL_SIGN){
              Sign sign = (Sign) e.getClickedBlock().getState();
              if(sign.getLine(0).contains(ChatColor.GREEN + "TeamDM")){
                  return;
              }else if(block.getType() != Material.SIGN_POST || block.getType() != Material.WALL_SIGN){
                  inventoryh.clear();
                  inventoryh.setItem(0, hn.Spawn());
                  inventoryh.setItem(1, hn.TeamDM());
                  player.openInventory(inventoryh);
              }
              }
            }else if(player.getItemInHand().getItemMeta().getDisplayName().contains("Kit Selector")){
                inventory.clear();
                inventory.setItem(2, hn.Warrior());
                inventory.setItem(4, hn.Archer());
                inventory.setItem(6, hn.Tank());
                player.openInventory(inventory);
            }else if(player.getItemInHand().getItemMeta().getDisplayName().contains("Apple of health")){
                player.addPotionEffect(new PotionEffect(PotionEffectType.HEAL, 2 ,0));
 
                Bukkit.getServer().getScheduler().scheduleSyncDelayedTask(plugin, new Runnable() {
                    public void run() {
                        player.setItemInHand(new ItemStack(Material.AIR));
                    }
                }, 1L);
 
                player.sendMessage(ChatColor.GREEN + "Je bent gehealed!");
            }else{
                return;
            }
        }

Please help

 

Error log where is the nullpointer getting throw at? @robberti

 

I think I already fixed it boysnnoco

But I got the nullpointer on this line

Code:java

else if(!player.getItemInHand().getItemMeta().getDisplayName().contains(ChatColor.GOLD + "Hub") && !player.getItemInHand().getItemMeta().getDisplayName().contains(ChatColor.GOLD + "Kit Selector") && !player.getItemInHand().getItemMeta().getDisplayName().contains(ChatColor.RED + "Apple of health")){
 
            }

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

you need to have a check if the itemInHand is null, and if it even has item meta with .hasItemMeta() (on the item stack) before you attempt getting it.

 

Mark thread as solved then?
