How to make an probability table using Weights?

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.

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!

Ultimately you can store the data any way you want. In this example I just stored it in a list of number,name;...

Mainly because it was simple to parse.
