Change the durability of the chestplate while flying?

How would I lower the durability from the chestplate your wearing while the player is flying? And which event?

 

I assume that you want to be using PlayerMoveEvent. You can check if the player is flying by using event.getPlayer().isFlying() and you can use player.getInventory().getChestplate().setDurability(durability) to change the durability of the chestplate.

 

Thanks this worked, but do you also know how to increase the durability and remove the item, because right now it just gives this long red bar.

 

Do you mean increasing the maximum durability of an item? If so, doing that requires with NMS code, and I'm not sure it will actually work...

If you just mean that you want to fix the long red bar, then increase the durability to its current durability -1, and it will slowly tick down.

To get rid of the item, use player.getInventory().setChestPlate(null)

 

Don't use the PlayerMoveEvent for that, it's "extremely CPU intensive".
You just have to schedule a task that runs every X ticks (10 represents half a second and is probably enough) and check if a player is flying inside.

 

Wolftic Just a warning, doing this will make the durability decrease, even if they're standing still (in the air).

 

How would I do this? Any samples of codes?

 

You can use Bukkit.getScheduler().scheduleSyncRepeatingTask()

Examples:
http://wiki.bukkit.org/Scheduler_Programming#Repeating_Tasks

 

Code:

Bukkit.getScheduler().scheduleSyncRepeatingTask(this, new Runnable() {
//variables
public void run() {
p.getInventory().getChestPlate().setDurability(p.getInventory().getChestPlate().getDurability()-1);
}
}, 0L, 20L);

Not tested

 

It says I have to change the "player"(Player player = getServer().getPlayer(getName()) to an final and i'm not quite sure where I have to put this, since ive never used that before :s

 

Code:

public void startPlayerTracking(final Player p) {
Bukkit.getScheduler().scheduleSyncRepeatingTask(this, new Runnable() {
//variables
public void run() {
p.getInventory().getChestPlate().setDurability(p.getInventory().getChestPlate().getDurability()-1);
}
}, 0L, 20L);
}

As always, not tested

EDIT: The schedule event gives a int id which you can use to stop the tracking
