Solved Random items in chest | HELP

I've managed to place random items in chests across my world, but they are set in a line (one after another). Where I want them to be randomly placed in slots in the chest. How can I modify the following code to do so?

Code:java

//Some code before this
 
if(b instanceof Chest)
                    {
                        Chest chest = (Chest) b;
                        Inventory chestInventory = chest.getInventory();
 
                        int o = 0;
                        Random randomvariable = new Random();
                        for(int i = o; i<randomvariable.nextInt(24); i++){
                            chestInventory.addItem(new ItemStack(mats.get(randomvariable.nextInt(mats.size())),
                            randomvariable.nextInt(1) + 1));
                            }
 
 
                    }
 
//END

I would use setItem instead of addItem and use a new random variable for the slot.

 

You can do what endoml said with setItem(int slotIndex, ItemStack item) and for the slotIndex you could either do just a random number between 0-chest size (which could lead to accidentally replacing an item you already set), or you could make a list of integers that contains 0-chest size and shuffle it. Using that list you can use the next number in the list and remove it to prevent accidentally replacing an item.

 

Xyplo You could do something like this to randomly choose the slot:

Code:java

chestInventory.setItem(rand.nextInt(27), theItem);

where theItem is an ItemStack of the material that your wish to put in a random slot.

Edit: And rand is just a new random

 

I forgot about this thread, this is pretty much what I did anyway XD
