Here is my code and the Error im getting can any one help me please on fixing it

 

@Lukas12137 Well, I can tell you that you are getting a NullPointerException in your SpawnBosses (PlayerInteractEvent) method.

Its a bit hard to read. Would you mind using code blocks for the code.

 

Well the plugin works but it throws this error when ever i break something or click on any block

 

@Lukas12137 I don't think this will fix it, but I rewrote your spawnbosses event. With that you shouldn't get any more NPE's. I think it was because you didn't have the right checks.

Code:

@EventHandler
public void spawnBosses(PlayerInteractEvent e) {
    Player p = e.getPlayer();
    ItemStack is = p.getItemInHand();
 
    if (is == null || is.getType() == Material.AIR) {
        e.setCancelled(true);
        return;
    }
 
    if (e.getAction() == Action.RIGHT_CLICK_AIR || e.getAction() == Action.RIGHT_CLICK_BLOCK) {
        if (is.getItemMeta().hasDisplayName()) {
            if (is.getItemMeta().getDisplayName().contains("§c§lThe Zombie God! §6§l(Click To Spawn)") && is.getType() == Material.PAPER) {
                Bukkit.getServer().dispatchCommand(Bukkit.getConsoleSender(), "gz");
                p.getInventory().setItemInHand(new ItemStack(Material.AIR));
            }
            else if (is.getItemMeta().getDisplayName().contains("§e§lThe Headless King! §6§l(Click To Spawn)") && is.getType() == Material.PAPER) {
                Bukkit.getServer().dispatchCommand(Bukkit.getConsoleSender(), "hk");
                p.getInventory().setItemInHand(new ItemStack(Material.AIR));
            }
        }
    }
}

 

Still throws out the same Error when i have an item in hand and i place it or click it/breake.

Fixed it i added a thing to if the player is not holding paper just return it and that seems to fix it.
