How can I confine this to a square?

I have a ball that follows the mouse, but I need to confine it to a box shape. I can do it with the dragable buttons but not this MC that follows the mouse.

Here is the code I have attached to the ball MC:

onClipEvent (load) {
    _x = 0;
    _y = 0;
    speed = 5;
}
onClipEvent (enterFrame) {
    targetx = _root._xmouse;
    targety = _root._ymouse;
}
onClipEvent (enterFrame) {
    _x += (targetx-_x)/speed;
    _y += (targety-_y)/speed;
}

Cheers.

Just one more step. Add this AS to the bottem of your AS:

onClipEvent (enterFrame) {
	startDrag(getProperty (_x,_y), true, 1, 1, 200, 200);
}

This confines it to a 200 by 200 box.

There’s no need for your 2nd onClipEvent.

onClipEvent (load) {
    _x = 0;
    _y = 0;
    speed = 5;
}
onClipEvent (enterFrame) {
    targetx = _root._xmouse;
    targety = _root._ymouse;
    _x += (targetx-_x)/speed;
    _y += (targety-_y)/speed;
}

onClipEvent (enterFrame) {
	startDrag(getProperty (_x,_y), true, 1, 1, 200, 200);
}

Excellent, thanks for the help dude :smiley:

Well that completely disables the easing code so it doesn’t follow the mouse with easing…

And all of that can be squished down into this simple code…

onClipEvent (enterFrame) {
	startDrag(this, true, 1, 1, 200, 200);
}

Produces the same effect.

Now for constraining the easing code, it goes like this…

onClipEvent (load) {
	_x = 0;
	_y = 0;
	speed = 5;
}
onClipEvent (enterFrame) {
	targetx = _root._xmouse;
	targety = _root._ymouse;
	_x += (targetx-_x)/speed;
	_y += (targety-_y)/speed;
	if (this._x<=1) {
		this._x = 1;
	}
	if (this._x>=200) {
		this._x = 200;
	}
	if (this._y<=1) {
		this._y = 1;
	}
	if (this._y>=200) {
		this._y = 200;
	}
}

2 things: getProperty sucks and no need to startDrag on enterFrame, you just do it once (on Load for instance) and it’s enough.

Yes, getProperty does suck.

And Ilyas… thanks for the info, I always thought startDrag had to go on an enterFrame to update its position. I never tried on Load though.

Thanks for the advice, I learnt a lot there.
