Durability Check

Hello, I've been trying to develop a plugin based on a friend's request that checks a player's tool and armor durability, and warns them if it's getting low. So far, I've gotten the tool check done for the most part, but I've got some questions:
1) Mainly, is there any easier way to check if the player has taken durability on an item such as some listener "onItemUse" or something? I know you can use PlayerInteractEvent, but I always have to check if a) The player is holding an item, b) If the item is a tool, c) If they're actually destroying the block, ca) If they aren't destroying the block, are they holding a shovel or hoe that takes durability in any other way, and cb) If the block is modifiable by the specified tool. Not to mention there's shearing to involve too.

2) If there isn't, is there at least a function that checks if the item is a tool (eg shovel, hoe, sword, pick)?

Here's my code for now, pretty messy, so any suggestions would be appreciated:

Code:

        {
            Bukkit.broadcastMessage(ChatColor.GREEN + "Item is at 10% durability!");
            player.playSound(player.getLocation(), Sound.ENTITY_PLAYER_LEVELUP, 30, 1);
            return;
           
        }
           
        if (item.getDurability() == fivePercent)

            return;
        }
       
    }

}

I'm more used to C++ than I am with Java, so I still needs some getting used to. Hope you understand!

 

If you want to learn more about Bukkit's class/events/method, this is the link you need. Please, bookmark/create a file with this link for when you have questions like this:
https://hub.spigotmc.org/javadocs/bukkit/

Under Events/Player, you will find the PlayerItemDamageEvent, which is called when an item changes its durability. Listen for this.

 

Thank you! I'll make sure to do that! And yes I've been scouring the javadocs for that kind of function, but just couldn't find one that I needed (still trying to get used to navigating the site). Nice to have some expert advice!

If your problem has been solved, mark this thread as solved.

 

It says "PlayerItemDamageEvent cannot be resolved to a type" and it has a red squiggly line under it. And it doesn't say any imports under it either.

 

@Side8StarLite
What version of bukkit/spigot are you using?

 

1.9.4 CraftBukkit
