Help on how to avoid random number to be equal to a variable

NinoBrown · March 30, 2011, 11:42pm

I’m new to AS3 and I’m trying to make a multiplication tables review to help kids learn their tables. The app shows a random equation “a * b = c” with four possible answers with randomly generated positions, three of which are randomly generated answers and one right answer and for the most part my code works fine, but im having trouble avoiding any of the three randomly generated answers to be the same as the right answer.

my code is on the timeline, here’s some of it


displayRandomNumber();
var a = wildCardNum;
var b = factorB.text;
var product:Number = 0;

factorA.text = String(a);
factorB.text = String(b);

product = a * b;

var answerPositionNumber:Number = Math.floor(Math.random() * 4) + 1;

randomAnswerPosition();


function displayRandomNumber()
{
    var high:Number = 10;
    var low:Number = 1;

    factorA.text = (Math.floor(Math.random()*(1+high-low))+low).toString();
    factorB.text = (Math.floor(Math.random()*(1+high-low))+low).toString();
}

function randomAnswerPosition()
{

    if (answerPositionNumber == 1)
    {
        answerPlace1.text = ""+product;
        answerPlace2.text = ""+Math.floor(Math.random() * 10) + 1;
        answerPlace3.text = ""+Math.floor(Math.random() * 10) + 1;
        answerPlace4.text = ""+Math.floor(Math.random() * 10) + 1;
    }
    if (answerPositionNumber == 2)
    {
        answerPlace2.text = ""+product;
        answerPlace1.text = ""+Math.floor(Math.random() * 10) + 1;
        answerPlace3.text = ""+Math.floor(Math.random() * 10) + 1;
        answerPlace4.text = ""+Math.floor(Math.random() * 10) + 1;
    }
    if (answerPositionNumber == 3)
    {
        answerPlace3.text = ""+product;
        answerPlace1.text = ""+Math.floor(Math.random() * 10) + 1;
        answerPlace2.text = ""+Math.floor(Math.random() * 10) + 1;
        answerPlace4.text = ""+Math.floor(Math.random() * 10) + 1;
    }
    if (answerPositionNumber == 4)
    {
        answerPlace4.text = ""+product;
        answerPlace1.text = ""+Math.floor(Math.random() * 10) + 1;
        answerPlace2.text = ""+Math.floor(Math.random() * 10) + 1;
        answerPlace3.text = ""+Math.floor(Math.random() * 10) + 1;
    }
