Need help with Javascript random stat generator (for RPG's)

[SgtBot]

Hi, I've been learning a lot of javascript recently and I began programming a script that would emulate how your starting stats are rolled in Dungeons and Dragons. I've never actually played d&d, but from what my roommates were telling me, your starting stats are acquired by rolling a 6 sided dice 4 times (or rolling 4 six side dice all at once) and then taking the highest three numbers and adding them up together. I programmed that like this:

function diceRoll(min, max) {
    return Math.floor(Math.random() * (max - min + 1) + min);
   }

   var rollSet1 = new Array();
    rollSet1[0] = diceRoll(1, 6);
    rollSet1[1] = diceRoll(1, 6);
    rollSet1[2] = diceRoll(1, 6);
    rollSet1[3] = diceRoll(1, 6);

This simulated rolling the 4 dice.

var set1Smol = (Math.min(...rollSet1));

This set the variable: "set1Smol" equal to the smallest number out of the 4 numbers in the array.

var stat1 = (rollSet1[0] + rollSet1[1] + rollSet1[2] + rollSet1[3] - set1Smol);

And this set the variable: "stat1" equal to the sum of all 4 numbers in the array - the smallest number in the array.

I did this for each of the 7 rollSets and put the "stat(x)" variables into a separate array, and then used the Math.min operator to find the smallest number out of all 7 stats.

var totalSetSum = new Array();
    totalSetSum[0] = stat1;
    totalSetSum[1] = stat2;
    totalSetSum[2] = stat3;
    totalSetSum[3] = stat4;
    totalSetSum[4] = stat5;
    totalSetSum[5] = stat6;
    totalSetSum[6] = stat7;

   var lowestStat = (Math.min(...totalSetSum));

Now the one thing I couldn't figure out was how to get rid of the smallest number in the totalSetSum array. Right now I have it just printing all 7 stats and then telling you which one is the smallest, but what I would like to do is create a character stat object with 6 properties that are equal to the 6 highest out of the 7 stats. Does anybody know how I would go about programming that? Any help would be appreciated! Thanks!

 

Here is a link to my github where I have the full javascript program located.

Pseudo code (not really javascript, just translate it over):

var index = 0;
for (i = 0; i < totalSumSet; i++)
	if (totalSumSet[i] < totalSumSet[index])
    	index = i;
totalSumSet.Remove(i);

In JavaScript you use splice.

 

totalSumSet.splice(i, 1)

That being said your code would remove everything smaller that the first item.

I created a fiddle for you. https://jsfiddle.net/ej8bjpmv/

Open the console in your browser and press run.

How so? It only removes one item. You seem not to have seen that it is pseudo code and not js that I wrote. It's not meant to be taken literally as js and just copy-pasted. The translation process from concept to code helps newer people learn by doing. 

 

var index = 0;

for (i = 0; i < totalSumSet; i++)
{
		if (totalSumSet[i] < totalSumSet[index]) 
        {
        	  index = i;
        }
}

totalSumSet.Remove(i);

Pseudo code with brackets. Only removes the smallest item.
