Could someone help me how do I create a probability with 2 arrays?

The problem is this, I created a npc for ticket exchange per item, and using Luckywhell that posted here in the forum, the item configuration is like this: IDItem, Quantity, Enchant, Chance.

But the chance is according to the quantity of items, not by chance of each item, could you help me to solve this problem?

Could you post some code in order to help us?

Why don't you edit the core to read it by chance value then? I guess would be easier and better.

 

Without seeing the code, I can't really understand how exactly it calculates the chance and what's the problem.

 

Show the code, explain it better, show an example or so. 

Every time I try to post, it gives error in the page: /

Pastebin. 

if (Rnd.get(100) > 50) //50% chance to
do that in array1
else //50% chance to

do the other array2

Example, the configuration looks like this: Item ID, Quantity, Enchant, and Chance

But even if I put the chance 000000001, if there are few items in the list, for example 4, the chance is going to be 1/4.

Ok, well, still you didn't provide important info. I had to find it on my own and looks like you are talking about Elfos' code, more or less?

Uppon config load it stores the info

 

public void add(double weight, E result)
{
    if (weight <= 0) return;
    total += weight;
    map.put(total, result);
}

public E next()
{
    double value = random.nextDouble() * total;
    return map.ceilingEntry(value).getValue();
}

 

So, the next return 0.0 - 1.0 * total . But still, I don't see any "chance calculation" over the code, else that's the chance itself? I guess?

Yes, I used the Elf code as a base, but I did a npc for it, the code itself, that's it.

 

I would simply drop the RandomCollection and eventually rework config load. Make it as you want it to be. 

As I'm not very experienced in java, would not I have a way to make it "functional" until I can redo?
