Hi everyone,

I have created a square movie clip and I tween it randomly using the caurina class within the available space in the stage,

how can I limit the space in the stage?

for example if my stage is 1000x1000 but I want my square only to tween randomly within 500x500px?

here is my code:

```auto

import caurina.transitions.*;

function trigger_mc()
{
    Tweener.addTween(cube_mc, {x:Math.random()*stage.stageWidth,
                           y:Math.random()*stage.stageHeight, y:300, time:1,
                           rotation:Math.random()*300, onComplete:trigger_mc,
                           transition:"easeOutBounce"});
}

trigger_mc();

```

thanks
