AS copy and paste

For the AS copy and paste function, FLASH uses AS to create copy and paste function classes. Let's take a look at the call method.

On (release ){
StopDrag ();
// End the action
}
On (press ){
StartDrag (this );
// End the action
Mx. behaviors. DepthControl. bringToFront (this );
// End the action
}
