Inventory: Anvil Events

Hello,

I do not know whether this already exists or if it is implemented in the latest builds, at least not in mine.
For my plugin I needed a way to access Anvil events, such as item renaming or combining tools to repair them.

Maybe someone finds this code useful:
Item Renaming

Code:java

 
@EventHandler(priority = EventPriority.MONITOR)
public void onInventoryClick(InventoryClickEvent e){
// check if the event has been cancelled by another plugin
if(!e.isCancelled()){
HumanEntity ent = e.getWhoClicked();
 
// not really necessary
if(ent instanceof Player){
Player player = (Player)ent;
Inventory inv = e.getInventory();
 
// see if the event is about an anvil
if(inv instanceof AnvilInventory){
InventoryView view = e.getView();
int rawSlot = e.getRawSlot();
 
// compare the raw slot with the inventory view to make sure we are talking about the upper inventory
if(rawSlot == view.convertSlot(rawSlot)){
/*
slot 0 = left item slot
slot 1 = right item slot
slot 2 = result item slot
 
see if the player clicked in the result item slot of the anvil inventory
*/
if(rawSlot == 2){
/*
get the current item in the result slot
I think inv.getItem(rawSlot) would be possible too
*/
ItemStack item = e.getCurrentItem();
 
// check if there is an item in the result slot
if(item != null){
ItemMeta meta = item.getItemMeta();
 
// it is possible that the item does not have meta data
if(meta != null){
// see whether the item is beeing renamed
if(meta.hasDisplayName()){
String displayName = meta.getDisplayName();
 
// do something
}
}
}
}
}
}
}
}
}
 

Item Repairing

Code:java

 
@EventHandler
public static void onInventoryClick(InventoryClickEvent e){
    // check whether the event has been cancelled by another plugin
if(!e.isCancelled()){
HumanEntity ent = e.getWhoClicked();
 
// not really necessary
if(ent instanceof Player){
Player player = (Player)ent;
Inventory inv = e.getInventory();
 
// see if we are talking about an anvil here
if(inv instanceof AnvilInventory){
AnvilInventory anvil = (AnvilInventory)inv;
InventoryView view = e.getView();
int rawSlot = e.getRawSlot();
 
// compare raw slot to the inventory view to make sure we are in the upper inventory
if(rawSlot == view.convertSlot(rawSlot)){
  // 2 = result slot
if(rawSlot == 2){
  // all three items in the anvil inventory
ItemStack[] items = anvil.getContents();
 
// item in the left slot
ItemStack item1 = items[0];
 
// item in the right slot
ItemStack item2 = items[1];
 
// I do not know if this is necessary
if(item1 != null && item2 != null){
int id1 = item1.getTypeId();
int id2 = item2.getTypeId();
 
// if the player is repairing something the ids will be the same
if(id1 != 0 && id1 == id2){
  // item in the result slot
ItemStack item3 = e.getCurrentItem();
 
// check if there is an item in the result slot
if(item3 != null){
ItemMeta meta = item3.getItemMeta();
 
// meta data could be null
if(meta != null){
  // get the repairable interface to obtain the repair cost
if(meta instanceof Repairable){
Repairable repairable = (Repairable)meta;
int repairCost = repairable.getRepairCost();
 
// can the player afford to repair the item
if(player.getLevel() >= repairCost){
// success
}else{
// bugger
}
}
}
}
}
}
}
}
}
}
}
}
 

 

Very useful, thanks

 

Tabs? Pastebin? naaah, for losers.

 

Hi I would really like to know if like I could check what block they are renaming and if it is like mushroom soup it get's cancelled.

 

Perfect! Its working!
