Detecting mouse movement

Example: If you do nothing with the mouse for about 3 seconds, hide the thumbnails. Otherwise, show a thumbnail.

How to do something like this?

You have to create a timer variable that will be reseted when the mouse moves. If the timer is bigger than the defined amount, the thumbnail will be hidden.

Here's a quite example (I haven't tested it but it should work)

Code:

---

// Copy this into the "When movie starts" script.
var timer:uint = 0;
var lastMouseX:uint = 0;
var lastMouseY:uint = 0;
const timerLimit:uint = 60; // in frames

// Copy this into the "On every frame" script
if(mouseX != lastMouseX || mouseY != lastMouseY)
        timer = 0;

element("thumbnail").visible = !(timer >= timerLimit);

lastMouseX = mouseX;
lastMouseY = mouseY;
timer++;

Let me know whether it works or if you need further help (e.g. for a smooth fading effect etc.)

Thank leifi. It works, but I wonder whether there will be better to use the command setInterval.

Code:

---

done = function()
{
        clearInterval(counter);
        element ("thumbnail")._visible = false;
}
counter = setInterval(done, 3000);
_root.onMouseMove = function()
{
        clearInterval(counter);
        counter = setInterval(done, 3000);
        element ("thumbnail")._visible = true;
}

I still have a lot of questions but I will return to these questions another time. Thank you again for helping.

Of course you can do it this way... But then it's better to use the Timer class of flash. The official documentation says:

Instead of using the setInterval() method, consider creating a Timer object, with the specified interval, using 0 as the repeatCount parameter (which sets the timer to repeat indefinitely).
