Solved removeItem(new ItemStack) Method

Hello, Please understand I am still learning JAVA and spoon feeding wont help me! Please try to explain your code a little, Many thanks!

At this current stage I am starting my creation into a Guild RPG Plugin for my server, Now I am not looking to get advanced right now as I am stuck at the bottom of the mountain right now and it is only the smallest thing that is affecting my progression.

I want to remove 4x64 of the item from the players inventory after checking that he has it, and if he doesn't have it then I want it tell them you can't buy a guild yet.

My code so far:

Code:

public boolean onCommand(CommandSender sender, Command command, String commandLabel, String[] args) {
        Player player = (Player) sender;
        if (commandLabel.equalsIgnoreCase("Guild")) {
            if (args.length < 1) {
                sender.sendMessage("You need to use one of the following:");
                sender.sendMessage("/guild create <name>");
                sender.sendMessage("/guild invite <name>");
                sender.sendMessage("/guild remove <name>");
            } else if (args[0].equalsIgnoreCase("create")
                    && player.getInventory().contains(new ItemStack(Material.GOLD_NUGGET, 64 * 4))) {
                sender.sendMessage("You just created a Guild, It costed you 256 Golden Nuggets!");
                player.getInventory().removeItem(new ItemStack(Material.GOLD_NUGGET, 64 * 4));
            } else {
                sender.sendMessage("You can't afford a Guild yet! Please go get 256 Gold Nuggets!");

                return true;
            }
        }
        return false;
    }

 

@JBAvodas
Because bukkit checks if the inventory contains the exact stack, and doesn't care about amounts. What you can do is:
1) Create an int and set it to the amount you want (in this case, 64 * 4 = 256)
2) Loop through the inventory's contents
3) Check if the item is not null due to empty slots
4) Check if the item's type is a gold nugget, then subtract the item's amount from the number created in step 1
5) After the loop, check if the number from step 1 is smaller than or equal to 0, if it is, remove the items using Inventory#removeItem(ItemStack) as that doesn't care about amount.

 

So, Would I do the following below my public class create an int as follows:

Code:

int guildcost = 256;

Then would I do the following:

Code:

for(int : guildcost)
{
   player.getInventory().contains(new ItemStack(Material.GOLD_NUGGET);
}

and if that is true then:

Code:

sender.sendMessage("");

but if it is false then

Code:

} else {
sender.sendMessage("");

return true;
}

am I on the right track? If not can you please give me an example

 

@JBAvodas
Please tahg me next time :/.
What I explained should be enough.

 

"for(int : guildcost)" will not work.
You are not looping through the items.

 

@megamichiel
I am very new to java coding and over the last week am still learning, I am not the sort who will go sit down and watch 100s of videos though and my best way of learning is to do it as I go.
I don't full understand what looping through items meant could you please give me an example of how something like this should be laid out? Thanks!

 

@JBAvodas
if (inventory.containsAtLeast(itemstack, itemstack.getamount()) ) {
inventory.removeItem(itemstack)
}

This is the best way for remove itemstack. If you have many stack to remove, do a loops. Im not sure you can set an amount of 400 and remove it like that.

 

@caderape
I understand all of that cader its the looping part I am stuck on. Can you give me an example of how the loop should look?

EDIT: I worked out how to do it using your containsAtLeast method! Thanks so much Cader! for anybody who would be wondering this is what I have ended up using:

Code:

} else if (args[0].equalsIgnoreCase("create")
                    && player.getInventory().containsAtLeast(new ItemStack(Material.GOLD_NUGGET), guildcost)) {
                sender.sendMessage(ChatColor.GOLD + "You just created a Guild, It costed you a 256 Gold Nuggets!");
                player.getInventory().removeItem(new ItemStack(Material.GOLD_NUGGET, 64));
                player.getInventory().removeItem(new ItemStack(Material.GOLD_NUGGET, 64));
                player.getInventory().removeItem(new ItemStack(Material.GOLD_NUGGET, 64));
                player.getInventory().removeItem(new ItemStack(Material.GOLD_NUGGET, 64));
            }

 

@JBAvodas
for (int i = 0; i < StackNumber; i++)
if (player.getinventoy.containsAtleast(itemstack, itemstack.getamount)
removeitem(itemstack);
