Activate something upon armor remove/place?

Hi,

So im making this simple plugin which allows u to fly if u are wearing the specific piece of armor.

Now, what i dont know how to achieve is, the way to check when the player placed the that specific piece of armor on himself or removed it.

Lets say we are using chestplate. As soon as he puts the chestplate on himself, he is granted flying, and as soon as he removes it, he cant fly anymore. So all suggestions are welcome.

 

You can use an InventoryDragEvent. Then check if the player is wearing, for example, a diamondchestplate. If this is true, set his flying to true. If it is not, set it so false.

For example:

Code:

if(player.getInventory().getChestPlate().getType() == Material.DIAMOND_CHESTPLATE)
  player.setFlying(true);
else player.setFlying(false)

How would i get the player? Since in the DragEvent it seems i cant get the player via

Code:java

@EventHandler
    public void onInventoryDrag(InventoryDragEvent e) {
        Player p = e.getPlayer();
 
    }
 

 

Use this:

Code:

if(e.getWhoClicked() instanceof Player)
{
  Player p = (Player) e.getWhoClicked();
}

 

Err - I'm not sure InventoryDragEvent is universal for something like this... Why not InventoryClickEvent?
When he clicks, check if the cursor has an item, if it does, check if it's a chestplate. If it is, then let the event pass and grant the player fly mode. Else, let the event pass and don't grant the player fly mode. You could also check for the specific slots of a PlayerInventory object if you want to make sure he's clicking the chestplate in the chestplate armor slot:

Edit: As an afterthought, you might also want to check the Player's gamemode and any other data involving MetaData, ItemMeta, or whatnot of the item.

Wait, i get it to the part when u say i can check specific slot. I need it to grant fly when he places chestplace in the chestplate slot, and when he removes it, fly is removed. I dont want to check it right away as he click the chestplate and starts dragin it across inventory. So, click a chestplate, once placed in the chestplate slot, can fly, when removed, flying removed.

And for the other part, ive got a custom recipe for that armor, and the way im checking for it is if the ItemMeta displayname matches the one of the chestplate

 

Hi. This is a bit of code I made a few years ago for boots that make you fly if you put them on and stop you flying if you take them off. Hopefully you can adapt it to your needs. I have commented it so you will be able to understand

Code:java

        @EventHandler
        public void onCloseInventory(InventoryCloseEvent ev){
            //if the inventory is a player's inventory
            if(ev.getView().getType() == InventoryType.CRAFTING || ev.getView().getType() == InventoryType.CREATIVE){
                Player player = (Player) ev.getPlayer();
                //get the players armor
                ItemStack[] armor = player.getInventory().getArmorContents();
                //cycle through the armor
                for(int i = 0; i < armor.length; i++){
                    if(armor[i].hasItemMeta()){
                        String itemName = getItemName(armor[i]);
                        //if the item doesnt have a special name e.g. "fly boots" return.
                        if(itemName != null){
                            //let the player fly
                        }
                    }
                }
            }
        }
 
        @EventHandler
        public void onInventoryClick(final InventoryClickEvent ev){
            final Player player = (Player) ev.getWhoClicked();
            //if the clicked slot is an armor slot or the hovered item is boots
            if(ev.getSlotType() == InventoryType.SlotType.ARMOR || ev.getCursor().getType().equals(Material.LEATHER_BOOTS)){
                //get the players armor
                final ItemStack[] armor = player.getInventory().getArmorContents();
                //wait one tick and check the players armor again
                plugin.getServer().getScheduler().scheduleSyncDelayedTask(plugin, new Runnable() {
                    public void run() {
                        //get the players armor
                        ItemStack[] armor2 = player.getInventory().getArmorContents();
                        for(int i = 0; i < armor.length; i++){
                            //compare the armor before and after the event
                            if(armor[i] != armor2[i] && armor[i].hasItemMeta()){
                                String itemName = getItemName(armor[i]);
                                if(itemName != null){
                                    //stop flying the player
                                }
                            }
                        }
                    }
                }, 1L);
            }
        }[/i][/i][/i][/i][/i][/i]

I forgot this method
private String getItemName(ItemStack item) {
return ChatColor.stripColor(item.getItemMeta().getDisplayName());
}
