function disappearNum(e){
   
}

function makeRandNum(){
    for(var i = 0; i < nums.length; i++){
        var curNumbers = new Text(nums[i]);
        var pastNumbers = new Text(nums[i] – 1);
        curNumbers.setPosition (Randomizer.nextInt(0 + curNumbers.getWidth(), getWidth() – curNumbers.getWidth()) , Randomizer.nextInt(0 + curNumbers.getHeight(), getHeight() – curNumbers.getHeight()));
        pastNumbers.setPosition (Randomizer.nextInt(0 + pastNumbers.getWidth(), getWidth() – pastNumbers.getWidth()) , Randomizer.nextInt(0 + pastNumbers.getHeight(), getHeight() – pastNumbers.getHeight()) );
       
       
        curNumbers.getX() != pastNumbers.getX()
        curNumbers.getY() != pastNumbers.getY()
       
        add(curNumbers);
    }
}

This is the code that I have so far, however feel free to correct anything if needed. I want to have the user go through the numbers from least to greatest and click them, making them disappear. There should be a timer that will end once they make all the numbers disappear. In addition, I would like an end screen along and please make sure the numbers 1-20 don’t overlap. I am willing to pay more if the code is done soon and all the functions work properly (this is a project for CodeHs)
