How to execute a script after message appears on users screen?

The biggest problem here is that I downloaded this dudes website with HTTrack and I've got my site to work almost fully. Yet this one part doesn't want to work. I want to swap his script with mine. Is there a way to make MY script stay dormant until 5 seconds after "You need to recharge your lightsaber." appears on the screen?

    }
    });
    loadingMessages.push({
        message:"Sending...",
    sleep:5000,
        after:function(){
            addStatus('<span class="greenDot"></span> <span class="white_text">Sandpeople killed successfully.</span>');
            $('.cpabuildSpinner').removeClass('redSpinner').removeClass("yellowSpinner").addClass('greenSpinner');
        }
    });
    loadingMessages.push(
            {
                message:"Checking for live sandpeople...",
                sleep:1000,
                after:function(){
                    addStatus('<span class="yellowDot"></span> <span class="white_text">More sandpeople are in the area.</span>');
                    $('.cpabuildSpinner').removeClass('yellowSpinner').removeClass("greenSpinner").addClass('redSpinner');
                }
            });
    loadingMessages.push(
            {
                message:"User not verified.",
                sleep:3000,
                after:function(){
                    addStatus('<span class="redDot"></span> <span class="white_text">You need to recharge your lightsaber.</span>');
                    $('.cpabuildSpinner').removeClass('yellowSpinner').removeClass("greenSpinner").addClass('redSpinner');
