ItemStack[] ArrayList

With this array:

Code:java

    public ArrayList<ItemStack[]> items = new ArrayList<ItemStack[]>();

how would I add a itemstack.

 

Code:

    public ArrayList<ItemStack> items = new ArrayList<ItemStack>();
    items.add(new ItemStack(Material.AIR));

 

Umm google java array list.javadocs. the answer is there.

Seriously its just .add
Should have learned it while learning about lists

 

SuperOmegaCow Something similar to this:

Code:java

public void addStack(ArrayList<ItemStack[]> list, ItemStack stack) {
ItemStack[] temp = { stack };
list.add(temp);
}

Just make a new ItemStack[] and make it equal whatever you want. My method is a fairly simple way of adding one IemStack[]. I'll edit this if I find a way of adding multiple. Alternately you can make it just ItemStack instead of ItemStack[] and use the method from the first post.

SuperOmegaCow Decided not to edit my last post. Here is a method for supplying as many ItemStacks as you want, I have not testing it but it should work (in theory):

Code:java

public void addStack(ArrayList<ItemStack[]> list, ItemStack... stack)
{
    List<ItemStack> temp1 = new ArrayList<ItemStack>();
    for (int x = 0; x < stack.length; x++)
    {
        temp1.add(stack[x]);
    }
    ItemStack[] temp2 = (ItemStack[]) temp1.toArray();
    list.add(temp2);
}

AoH_Ruthless JRL1004 Maybe I have a improper import because it gives me an error... that is why I came here:

Code:java

items.add(new ItemStack(Material.BOW), 1);

 

SuperOmegaCow No, you are getting that error because you need to put an ItemStack[] and are supplying just an ItemStack.

 

SuperOmegaCow
ItemStacks don't have the integer attached to it; remove it and you should be all set.

Edit: JRL1004
I believe he is using what I did in a previous post.

 

AoH_Ruthless If so then what you put should be fine, otherwise they can use my post.

 

SuperOmegaCow
I just noticed that your integer was in the wrong location. The proper way:

Code:java

items.add(new ItemStack(Material.BOW, 1));

The import you should use is this:

Code:java

import org.bukkit.inventory.ItemStack;

 

AoH_Ruthless JRL1004 thanks this worked for me:

Code:java

public class ArenaClasses {
 
    public String player;
    public String character;
    public ArrayList<ItemStack[]> items = new ArrayList<ItemStack[]>();
 
    public ArenaClasses(String p, String character) {
        this.player = p;
        this.character = character;
        switch (character) {
        case "Archer":
            this.setArcher();
            break;
        case "":
            break;
        }
 
        for(int i = 1; i < items.size(); i++) {
            Bukkit.getPlayer(this.player).getInventory().addItem(items.get(i));
        }
 
    }
 
    public void setArcher() {
        ItemStack[] temp = { (new ItemStack(Material.BOW, 1)) };
        items.add(temp);
    }
 
 
 
}

And thank you Not2EXceL for nothing.

 

Why are you doing that at all, though? Unless you need to save multiple arrays of itemstacks, which you're not doing, just use a list of ItemStacks. Also you should use .clone() when you get the item.

 

why using ItemStack[] in a ArrayList this can be very nasty... people told me that ItemStack already can be nasty and serializing is alot better though depending what you need because other way you also are saving things which you may not want to use like ItemMeta thats why I say it depends.

i've wrote here almost the same thing in one of my psuodo codes how to make a ItemStack[] from a ArrayList though I haven't checked myself if it works.

Garris0n xize it is an object btw.

 

SuperOmegaCow So I helped you with nothing ehh?

Your working code

Code:java

 
public void setArcher() {
ItemStack[] temp = { (new ItemStack(Material.BOW, 1)) };
items.add(temp);
}
 

What I told you to do

Code:

Umm google java array list.javadocs. the answer is there.
 
Seriously its just .add

What my method comes up with:

Code:

[URL]http://docs.oracle.com/javase/7/docs/api/java/util/ArrayList.html[/URL]
add(E e)
Appends the specified element to the end of this list.

I clearly told you the exact way to solve your problem. So now you proceed to go f yourself if you think I didn't help. I gave you the tools to solve it yourself.

I still don't get why you have a list of ItemStack array's when you're not even using the array portion. You're just putting a single item array into the list from what's shown. It's a waste of resources to create a new array when its uneccessary

 

SuperOmegaCow
yes all these are 'Object' in some term but since it has its class reference it tells java what to do with it also in the IDE
just a quick question are you using the bukkit.jar api in your references directory? because this is needed so it doesn't say Object to these ItemStacks and so on you can use ItemStacks as ItemStacks instead of Objects.

 

An ItemStack when used like this is an object....

 

Not2EXceL thats true when its used as [], but I don't fully understand his question.

 

umm..
ItemStack == Object
ItemStack[] == array of ItemStacks

bukkit doesn't handle ItemStacks in any way other than objects.

 

Not2EXceL that is true but without a reference to it, it could be a Object but underfined as.
thats why I asked the op if he added the bukkit api inside the references.
though I believe if its not added it shouldn't see it as a Object inside the IDE though but rather more than a error but in case it shows it as a Object then the bukkit api isn't added correct inside the references folder.

in eclipse whenever I hover over my ItemStack[] it shows: org.bukkit.inventory.ItemStack if it said Object there something is terible wrong that is what I try to explain.

every thing is handled with Objects but have their own references to tell java what it does but Object it self means undefined which is really strange here.
