I have seen tutorials on how you can constrain a MC so it does not leave a squared area, however none for circled areas? is it possible with flash and if so, any links tutorials or examples?
Cheers.

2_pi_r\*squared… I am going to sleep in a bit so I cant post code, but do this: pick your center point (for the circle constrain - flash gives your cords) and use geometery to define the area for your MC - basically modify the rectangular code.
Hope this helps a bit - try it, if you still dont know where to go: post! Either way… GOOD NIGHT 😛
Peace

Yea, I had a feeling that some mathamatical formula would be required, thanks for the speedy replies guys. Well I hope some forum members here know that code or have a link to it, I await your replies 😉
