[1.7.10] Give player random items

[Bugzoo]

So if I have a list of 20 items, I want it to give the player 5 random items from that list of 20

[knokko]

Create a static randomizer and change the value every tick.

[TheDav1311]

You should double the list if you need it twice.

 

Random rand = new Random();

for(int m = 0; m < 6; m++)
{
          int r = rand.nextInt(YOURLIST.size() - 1);
          ItemStack stack = YOURLIST.get(r);
          player.inventory.addItemStackToInventory(stack);

   //if you want not 2 times the same one
          YOURLIST.remove(r); 
}

          YOURLIST.remove(r); 
}

 

MyList.get and MyList.remove dont work

[TheDav1311]

What kind of list you use?

What kind of list you use?

An ItemStack array

[TheDav1311]

With a Array I don't know how to delete, but you get it in this way.

 

Random rand = new Random();

for(int m = 0; m < 6; m++)
{
          int r = rand.nextInt(YOURLIST.size() - 1);
          ItemStack stack = YOURLIST[r];
          player.inventory.addItemStackToInventory(stack);
}

 

I would use a ArrayList in your situation.

That doesnt seem to be giving me any items at all

[TheDav1311]

In this case I need your full code

package com.bugzoo.Lootcube;

import java.util.Random;

import net.minecraft.creativetab.CreativeTabs;

public class ItemPokepack extends Item{
public ItemPokepack(){
	setMaxStackSize(1);
	setUnlocalizedName("pokePack");
}

@Override
public ItemStack onItemRightClick(ItemStack itemStack, World world, EntityPlayer player){
	Random rand = new Random();

	for(int m = 0; m < 6; m++)
	{
	          int r = rand.nextInt(Lootcube.pokelist.length - 1);
	          ItemStack stack = Lootcube.pokelist[r];
	          player.inventory.addItemStackToInventory(stack);
	}
	return itemStack;
}


}

 

MyList:

public static ItemStack[] pokelist = {new ItemStack(Cascoon), new ItemStack(Silcoon), new ItemStack(Purugly), new ItemStack(Gothita), new ItemStack(Watchog), new ItemStack(Dunsparce), new ItemStack(Sunkern), new ItemStack(Wormadam), new ItemStack(Patrat), new ItemStack(Luvdisk), new ItemStack(Mewtwo), new ItemStack(Charizard), new ItemStack(Arceus), new ItemStack(Lugia), new ItemStack(Slaking), new ItemStack(Dragonite), new ItemStack(Mew)};
   

[Bugzoo]

I found out that if I even give the player pokeList[1] it doesnt give the player anything, so it must be something up with the array

[Bugzoo]

anybody?

[coolboy4531]

You need to return the "stack" not the originally itemStack field.

[Bugzoo]

You need to return the "stack" not the originally itemStack field.

I cant return stack because it will only be made if the for loop runs. And if i make a public ItemStack variable, that just crashes the game

[MultiMote]

Store Item links (Mymod.someitem etc.) in your array. NOT ItemStacks. Create new ItemStacks from items in your loop.

Still doesnt give me any items

List:

public static Item[] pokelist = {Cascoon, Silcoon, Purugly, Gothita, Watchog, Dunsparce};

[sequituri]

You IDE is not giving you an error message about this nonsense:

public static Item[] pokelist = {Cascoon, Silcoon, Purugly, Gothita, Watchog, Dunsparce};

Class names are not items. Do you even read error messages? On the other hand, many new coders name instances with initial cap... either is very wrong.

I'm still not getting any items when I right click

[MultiMote]

I tested it and it works. Recheck your code.

What did you have as your array?

[daafganggdg]

I'd just use this:

    
Random rand = new Random();
        ItemStack[] itemstack = new ItemStack[20];
        itemstack[0] = new ItemStack(Items.apple, 2);
        itemstack[1] = new ItemStack(Items.bread, 34);
        //...
        for(int i = 0; i < 5; i++) {
        	player.inventory.addItemStackToInventory(itemstack[rand.nextInt(20)]);
        }

        //...
        for(int i = 0; i < 5; i++) {
        	player.inventory.addItemStackToInventory(itemstack[rand.nextInt(20)]);
        }

Thank you, this works. I dont know how I didnt think of that earlier. But im having a problem where sometimes it gives me 3 items, sometimes 4 and sometimes 5

uhhm, U have to put itemstack[2] = new ItemStack(theItemYouWant, TheAmountUWant);

and so on ofc into there too (up too 19).

If you have already done that and its still not working show your code. And if its adding e.g. 5 eggs 3 eggs u dont get 5 and 3 eggs but 8 in one stack ofc. And I dont know if you want to deny the chance of an ItemStack beeing added twice, if so u have to put in a check for that.
