I have a question about how can I do a good Probability Table using Weights, like the default one a lot of games have, as example: Minecraft Loot Tables.

I have this .txt imgur.com/a/eLmdTDp with some weighted values, 10 being the most common and 1 the rarest. The print doesn't show the total, but it's 264 possibility values.

So, I want to know a good way to choose one of these values by probability, if you know any type of solution or you can help, i would really appreciate!

Easy fix is to move to Construct 3 lol. I guess you could add values to rows of an array and pick a random row.

Sadly this is a construct 2 How do I forum. By the way, explain me more about the array solution, how could I suit it in a way that would work with all the values of the .txt?

If you put all those values in an array and just get one at random that would work.

Array.at(int(random(Array.width)))

For a more deluxe and compact version you could store the values and weights of each value. The sum of all the weights should be 1.

Then to randomly pick a value based on the weights you’d:

1. Generate a random value 0-1

2. Loop over the array

3. If the current weight<value? Then subtract the weight from the value and look at the next array position.

4. If weight>=value then you’re done and the array position you’re on is the value to use.

Anyways that’s the gist of it at least.

I've understanded it a bit, but I think would be better if you make an .capx for me to see how to do it, the .txt is here if you need ghostbin.com/aEb1P and all of the weighted values are stored in the ♣ symbol.

Like you said, the way that I want it to be is by having the chance to get choosed by the item weight value.

By the way, thanks a lot for helping me sir, I'm really glad!
