How to make an item auto repair?

What I tried?

Code:

            Bukkit.getServer().getScheduler().scheduleSyncRepeatingTask(this, new Runnable(){
 
                @Override
                public void run() {
                    if(LO.getDurability() != 0){
                        LO.setDurability((short) 0);
                    }
                   
                }
               
            }, 0, 1);

 

If you want the item to get autorepaired on time, do a scheduler.
Else do a while true to set the item they are holding, if it is a pickaxe for example, repair it.
Remember to not overwrite it because of it can be an enchanted one.

 

winitro You should make it so when they break a block or when it gets to a certain durability change it rather than doing a task which could cause lag with lots of players.

 

i think that setting the durability to -1 you make it indestructible. im not sure.
