[ANSWERED] chance.js Javascript Library

[jtsteph]

Hello,

I am trying to use the chance.js javascript library. 

https://chancejs.com/

I have placed it in the Javascript Libraries folder and am testing using various iterations of this:

include("chance.js");
function main() {
    let a = chance.d20(); // Rolls a random 20-sided dice
    return a;
}

The javascript window does not report an error when closing, so i assume it is finding the library file. The monitor is telling me that chance is not defined.

Am i doing this correctly? Is it that the chance.js library is incompatible with the isadora javascript engine?

I would appreciate any input here.

Thanks, J

I am interested in this to generate random numbers between ranges - but similarly was unable to get the chance.js library to take in Isadora.

I did manage a solution that fits my purpose using 'math.random' function:

// pseudo-random number generator between min and max range
// iz_input 1 "trigger"
// iz_input 2 "min"
// iz_input 3 "max"
// iz_output 1 "random"
function main()
{
a = arguments[0];
d = arguments[1];
e = arguments[2];
const minCeiled = Math.ceil(d);
const maxFloored = Math.floor(e);
  {
return [ Math.floor(Math.random() * (maxFloored - minCeiled + 1) + minCeiled)]; 
  // The maximum is inclusive and the minimum is inclusive
}
}

best wishes

@bonemap , Thanks for this. I was excited about the chance.js library because it offered random outputs to so many data types which would make things quite efficient here. I will try your method and am sure i could use it to work with other data types.

Next up, I want to try papaparser.js for csv files. It looks promising.
