I’m trying to get a movieclip to constantly rotate either left or right.  
At first I set this.\_rotation=-1  
Then I was thinking of using

[COLOR=Blue] if (this.\_rotation==1) {  
this.\_rotation = -1;[/COLOR]

But this only makes the object rotate 1 degree and then stop. How do I make it constantly rotate?

</div>

use [COLOR=Red]onEnterFrame [/COLOR]or [COLOR=Red]setInterval [/COLOR]function to rotate your object.

I am giving sample code below:

// Assuming you named ur object, my\_mc

```php

onEnterFrame = function() {
  my_mc._rotation++;
}

```

for setInterval function

```php

var interval = setInterval(rotatemc, 100, my_mc);
function rotatemc(mc:MovieClip) {
    mc._rotation++;
}

```

Do you want it to switch rotation direction at some point?

Great, I’m gonna try that out, Pandu.

And yes Macsy, I also want it to change direction when it hits the right or left edge of the screen.  
But I know how to get it to bounce back atleast. 🙂
