Before you post, please note that I know how to generate random stats using Math.random().

What I need is a formula, using Math.random, that creates a lower chance of getting higher numbers. I’ve thought about this, and I’m positive there is a simple solution, but I can’t think of one that doesn’t involve doing Math.random\*100 and then using if’s to assign the damages.

If you know of a simple formula which will have a better chance to output small numbers then high using math.random please answer.

you mean like a critical chance of getting something?

i would say something like this

```auto

function generateRandomNumber(){
    var n=Math.random()*100
    var r
   if(n>85){
       r=Math.random()*100
    }else{
      r=Math.random()*50
   }
return r
}

```

now with this code, just because you have a chance of getting it does not mean that you will get a higher number it just means that you will have a chance, if this is what you want

after playing around I came up with this: Math.round(((Math.random()\*30)/((Math.random()\*20)+1))+5);

lots of brackets, I know, I’m sorry.  
The first number is the max damage (-5), and the second number is the limiter. 30 is nearly impossible to get, 20’s are rare, 10’s are uncommon. The most common number seems to be 7 (2+5). This looks like it might work. The idea behind it is that the generator has to generate a 30 (1 in 30 shot) then a 0(1 in 20 shot) to output 35. That’s 1 in every 600 which is good enough for me 🙂

sure if thats the way you wan’t to do it, i prefer functinos better though easier on the eyes
