    Desktp to Touchscreen

    I have created an eLearning course using Flash CC5.5 and it works well when operated via a browser on a desktop or laptop PC. However my customer also wants the course to be navigated via touchscreen monitors. Apart from possibly enlarging the buttons is there anything else I will need to ammend? Will all the exsisting onclick etc AS work with touch interaction? Many thanks, Miles.

    Hi Miles,

    I can't remember where I got this code:

    function touchHandler(event) {
    var touches = event.changedTouches,
    first = touches[0],
    type = "";
    switch (event.type) {
    case "touchstart":
    type = "mousedown";
    break;
    case "touchmove":
    type = "mousemove";
    break;
    case "touchend":
    type = "mouseup";
    break;
    default:
    return;
    }

    var simulatedEvent = document.createEvent("MouseEvent");
    simulatedEvent.initMouseEvent(type, true, true, window, 1, first.screenX, first.screenY, first.clientX, first.clientY, false, false, false, false, 0 /*left*/ , null);
    first.target.dispatchEvent(simulatedEvent);
    event.preventDefault();
    }

    document.addEventListener("touchstart", touchHandler, true);
    document.addEventListener("touchmove", touchHandler, true);
    document.addEventListener("touchend", touchHandler, true);
    document.addEventListener("touchcancel", touchHandler, true);



    Also you should remove all on-rollover functionality.

    You'll have to give specifics about the touchscreen monitors. Are you talking about specific set of devices or "touchscreen monitors" in general?
