Solved InventoryClickEvent...Advanced

This is the inventory that is being created...It is basically an Item Menu.
.

Code:java

Public Inventory createInventoryPERK(){
pot = Bukkit.createInventory(null, 9, ChatColor.BLUE + "Perks"); // (owner, size (int), name)
 
//Add Items
 
pot.setItem(0, BACK);
      pot.setItem(1, REGAN);
      pot.setItem(2, SPEED);
      pot.setItem(3, STRENGTH);
      pot.setItem(4, INVISIBILTY);
    return pot;
}
 

Basically I am trying to get the player that opens that inventory
I need to get the player that opens the inventory because I need that to determine if the player bought the item or not.
Here is how it tells them if they bought the item

Code:java

 List<String> ls = new ArrayList<String>();
        ls.add(ChatColor.GRAY + "----------");
        if(((Permissible) p).hasPermission("Snipecraft.Regen")){
            ls.add(ChatColor.GREEN + "Purchased");
        }else {
        ls.add(ChatColor.GOLD + "Cost:");
        ls.add(ChatColor.GREEN + "50 Emeralds");}

Here is how they see the item in the inventory that they opened up

Code:java

  ItemStack REGAN = cname(new ItemStack(Material.PUMPKIN_PIE), ChatColor.LIGHT_PURPLE + "Gives you Meds", ls);
      ItemMeta REGANMeta = REGAN.getItemMeta();
      REGAN.setItemMeta(REGANMeta);

This is what stores the player the item they selected
This section of code is not part of the Inventory.
It is instead a click listener. So when a player clicks on the item Pumkin_Pie this is executed.

Code:java

 
@EventHandler
public void click(InventoryClickEvent event){
if (event.getInventory.getSize() == 9) {
event.setCancelled(true);
if(event.getCurrentItem.getType() == Material.PUMKIN_PIE){
if (!p.hasPermission("Snipecraft.Speed")){((CommandSender) p).sendMessage(ChatColor.BLUE + "You have to buy this Perk!");return;}
            ((Player) p).playSound(p.getLocation(), Sound.FIRE_IGNITE, 1f, 1f);
            List<String> ls = new ArrayList<String>();
            ls.add(ChatColor.BLUE + "Click to activate");
                        ItemStack pk = cname(new ItemStack(Material.DIAMOND_BOOTS), ChatColor.LIGHT_PURPLE + "Speed", ls);
                        perk.put(p.getName(), pk);
        ((CommandSender) p).sendMessage(ChatColor.BLUE + "Perk:" + ChatColor.LIGHT_PURPLE + " Speed");}}}
return;}}

This gives them the item they selected

Code:

ItemStack retrieve5 = perk.get(po.getName());
po.getInventory().addItem(retrieve5);

I gave you this long detailed list of code so you know exactly what is going on code wise.
Again the problem is that I am trying to get the player who is viewing the inventory......so it gets their
stats. Stats are determined by permissions, as you see above in the ArrayList example. I will take any question you ask...Thanks for reading this very long help message.

event.getView().getPlayer(), cast to Player because it returns a HumanEntity I believe

 

So, I can set

Code:java

Player p = (Player) event.getView().getPlayer();

This Is what I put so far...haven't tested it yet.

Code:java

public Inventory createInventoryPERK(){
pot = Bukkit.createInventory(null, 9, ChatColor.BLUE + "Perks"); // (owner, size (int), name)
InventoryClickEvent event2;
InventoryClickEvent event = event2;
Player p = (Player) event.getView().getPlayer();
//rest of Inventory
}
 

Good thing: No error in code

ASHninja1997
It should be inside the InventoryClickEvent handler

 

xTrollxDudex
well....That's my problem
I want it to when a player's mouse hovers over the item...it tells them, through permissions, if they have Purchased the item or not. That why I need to get the player viewing the Inventory.
If you don't understand what I am saying...Hypixel's server, QuakeCraft, will serve a fine example for that. In his Inventory GUI...It tells you if you have unlocked that item or not and what you need to do to get it...My Inventory GUI is very similar. Ask if you need more Description. I will be glad to give it.

 

ASHninja1997
That would mean you need to edit the inventory before it is opened.

 

xTrollxDudex
Humm...I think I know what your saying. Let me try something out then get back to you.

xTrollxDudex
Ok I think I got it to almost work....There are no errors in the code but when I try to open it there is a NPE in the console.
Ok so instead of opening a separate method I made a variable that equals a inventory...I basically did what you told me and I put the code that creates the inventory inside the InventoryClickEvent.
Here is the code that I changed

Code:java

@EventHandler
public void click(InventoryClickEvent event) {
if (event.getInventory().getSize() == 9) {
event.setCancelled(true);
if (event.getCurrentItem().getType() == Material.BEACON){
    HumanEntity p = event.getWhoClicked();
    p.closeInventory();
    ((Player) p).playSound(p.getLocation(), Sound.BAT_TAKEOFF, 1f, 1f);
    p.openInventory(pot);
    pot = Bukkit.createInventory(null, 9, ChatColor.BLUE + "Perks"); // (owner, size (int), name)
        List<String> ls = new ArrayList<String>();
        ls.add(ChatColor.GRAY + "----------");
        if(p.hasPermission("Snipecraft.Regen")){
            ls.add(ChatColor.GREEN + "Purchased");
        }else {
        ls.add(ChatColor.GOLD + "Cost:");
        ls.add(ChatColor.GREEN + "50 Emeralds");}
 
        List<String> ls2 = new ArrayList<String>();
        ls2.add(ChatColor.GRAY + "----------");
        if(p.hasPermission("Snipecraft.Speed")){
            ls2.add(ChatColor.GREEN + "Purchased");
        }else {
        ls2.add(ChatColor.GOLD + "Cost:");
        ls2.add(ChatColor.GREEN + "50 Emeralds");}
 
        List<String> ls3 = new ArrayList<String>();
        ls3.add(ChatColor.GRAY + "----------");
        if(p.hasPermission("Snipecraft.Strength")){
            ls3.add(ChatColor.GREEN + "Purchased");
        }else {
        ls3.add(ChatColor.GOLD + "Cost:");
        ls3.add(ChatColor.GREEN + "50 Emeralds");}
 
        List<String> ls4 = new ArrayList<String>();
        ls4.add(ChatColor.GRAY + "----------");
        if(p.hasPermission("Snipecraft.Invisibility")){
            ls4.add(ChatColor.GREEN + "Purchased");
        }else {
        ls4.add(ChatColor.GOLD + "Cost:");
        ls4.add(ChatColor.GREEN + "50 Emeralds");}
 
      ItemStack BACK = new ItemStack(Material.ENDER_PEARL, 1);
      ItemMeta BACKMeta = BACK.getItemMeta();
      BACKMeta.setDisplayName(ChatColor.LIGHT_PURPLE + "Back");
      BACK.setItemMeta(BACKMeta);
 
      ItemStack REGAN = cname(new ItemStack(Material.PUMPKIN_PIE), ChatColor.LIGHT_PURPLE + "Gives you Meds", ls);
      ItemMeta REGANMeta = REGAN.getItemMeta();
      REGAN.setItemMeta(REGANMeta);
 
      ItemStack SPEED = cname(new ItemStack(Material.DIAMOND_BOOTS), ChatColor.LIGHT_PURPLE + "Increase your Speed", ls2);
      ItemMeta SPEEDMeta = SPEED.getItemMeta();
      SPEED.setItemMeta(SPEEDMeta);
 
      ItemStack STRENGTH = cname(new ItemStack(Material.GOLD_CHESTPLATE), ChatColor.LIGHT_PURPLE + "Increase your Strength", ls3);
      ItemMeta STRENGTHMeta = STRENGTH.getItemMeta();
      STRENGTH.setItemMeta(STRENGTHMeta);
 
      ItemStack INVISIBILTY = cname(new ItemStack(Material.GLASS), ChatColor.LIGHT_PURPLE + "Gives you Invisibility", ls4);
      ItemMeta INVISIBILTYMeta = INVISIBILTY.getItemMeta();
      INVISIBILTY.setItemMeta(INVISIBILTYMeta);
 
      pot.setItem(0, BACK);
      pot.setItem(1, REGAN);
      pot.setItem(2, SPEED);
      pot.setItem(3, STRENGTH);
      pot.setItem(4, INVISIBILTY);
    return;
}

ASHninja1997
Where's the NPE

 

xTrollxDudex
Sorry for the very late reply

 

Whats on line 128 of snipecraft.java?

 

ASHninja1997
Switch lines 9 and 10 around. The null for createInventory should be (Player) p

 

xTrollxDudex
What do you mean line 9 and 10..those are imports.

Atakyn

Code:java

    p.openInventory(pri);

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

I think he meant switch these:

1. p.openInventory(pot);
2. pot = Bukkit.createInventory(null, 9, ChatColor.BLUE + "Perks"); // (owner, size (int), name)

p.openInventory(pot);
pot = Bukkit.createInventory(null, 9, ChatColor.BLUE + "Perks"); // (owner, size (int), name)

These two, you need to define pot before you can open it

I think I solved it...let me test it out

xTrollxDudex Atakyn
IT WORKS!!!!!!!!!!!!!!!!! xTrollxDudex You are the best!!!!!
Atakyn Thank you so much for the understanding!!!
