Solved How can I ensure both randomly generated colors are not the same?

[newbiSoso]

I'm making a simple game where two shapes change colors repeatedly using a timer, I have an array of colors to choose from how can I make sure both shapes will have be colored differently?

My code:

property variant colorArray: ["#008499","#963A65","#01FF97","#FF4140"] //colors to choose from
Timer{
        id: color_switch
        interval: 1000; running: true; repeat: true
        onTriggered: {
            shape1.color = colorArray[Math.floor(Math.random()*3)]
            shape2.color = colorArray[Math.floor(Math.random()*3)]
        }
    }

So in some shape or form you have to write a tiny bit of code there which checks: while the second call to Math.random() * 3 returns the same as the first call did, call it again!

Just genereate 2nd index until it is not same as 1st index:

        let idx1 = Math.floor(Math.random() * 3);
        let idx2 = Math.floor(Math.random() * 3);
        while (idx2 === idx1)
            idx2 = Math.floor(Math.random() * 3);
