Hi, I use standard code for Movie_Clip movement:

onClipEvent (enterFrame) {
if(Key.isDown(Key.RIGHT)) {
_x += 10;
}
}

But in that case, MC can move unlimited and continue to move out of the screenview. Is there some code for limited move, till certain position only? For example, when MC arrives to position _x=200, it can not move any more in that direction, it just can come back. So, it could move in _x(+) direction only when _x<200.
