JBUM, one for you!

[oldnewbie]

We've talk about this...

How would I get this happening as it is but based on the center of the rectangle, rather than on the left side (xpos = 0), when you test this in the application?
Hope this is somewhat clear!

[Adam14]

Is this what you were looking for?

Nice to see you Old, been a long time since I've been here

//edit..holy crap, you're almost at 20,000 posts :P

somehow, when I edited, it deleted my file

[oldnewbie]

Exactly! Thanks! Now I want it contained within, let's say 50 on the left and 500 on the right!

[Adam14]

I did this recently for a site, and I put an mc over top of the "hit" area, and tested for the mouse hitting it..would that work?

I did it here:
http://www.shavasana.com/flash.html
the scroll thing at the top

//edit

actually, this works, but it's a little sketchy:

code:

---

onClipEvent (load) {

	speed = 5;

}

onClipEvent (enterFrame) {

	// reverse mouse coord

	if(_root._xmouse>=50 && _root._xmouse<=500){

	var imx = ((Stage.width/2)+(this._width))-_root._xmouse;

	// convert to ratio (0 - 1)

	_x += (imx-_x)/speed;

	}

}

Maybe... But it would sort of be containing the people in that window, on either side...

That said there's somewhat awkward in your other file...

Look at the position of the mouse on the left, when the ball is just leaning on the right border, then the mouse position on the right, when the ball is leaning on the left border... Not the same. Nor does it work the same at all, when screening the .swf?

[Adam14]

Holy crap!! just tested the swf by itself..that is messed up

[Adam14]

Ok, this one works perfect when tested as the swf by itself.

//edit....or even better, 'cause you're not relying on the start position of the ball:

code:

---

onClipEvent (load) {

	speed = 5;

}

onClipEvent (enterFrame) {

	var imx = Stage.width-_root._xmouse;

	_x += (imx-_x)/speed;

}

Pretty good! Curious how it handles in the application...

Trying to set different left and righ offsets now... Think something is somewhat working...

Thanks for the help!

[Adam14]

After how many times you've helped me!!!! Man, I'm happy I could help out

[Adam14]

this sets limitations:

code:

---

onClipEvent (load) {

	speed = 5;

}

onClipEvent (enterFrame) {

	if(_root._xmouse<Stage.width/2){

	var imx = Stage.width-_root._xmouse-50;

	_x += (imx-_x)/speed;

	}else if(_root._xmouse>Stage.width/2){

		var imx = Stage.width-_root._xmouse+50;

	_x += (imx-_x)/speed;

	}

}

I'm just not that good at maths stuff! Never liked maths, and still don't!

[Adam14]

Replying, just to make sure you see my above post before you spend too long on it.

I was ok with math stuff, but when it comes to as, I just fiddle around until I find something that works...and then I try to figure out what I did

//edit. nah nevermind, that one messes up if you're right around the center...

[oldnewbie]

But it sort of gets sticky if you hover slowly over the middle, no?

Was just answering the above, while you were posting the above...

[oldnewbie]

And why does it seem to jump on that link you posted?

[Adam14]

arg..just worked on it some more and made even more of a mess of it!! I'm off to bed, good luck with it, oldnewbie

As far as the jumping on that link, it's a hitTest on a mc over the scroll thing, if you hit it "off center" if reacts according to the script. Not perfect, but you know my experience with flash, surprised I pulled that one off actually

good luck,
Adam

[oldnewbie]

Nighty! Catch you another day maybe!

[jbum]

Looks like I missed this one. I did the 50-500 thing by replacing this line, in your original:

endX = _root._xmouse*-ratio;


with this:

endX = (500-50)*ratio + 50;

[oldnewbie]

Cool! Can even change those numbers for different offsets...

Now, why doesn't this work properly when tested in the application?

And one last question... What if I wanted it to move according to the mouse's position but not on the whole stage's width... say 20 pixels from either the left or the right border?

[jbum]

Basically the trick is getting whatever mouse range you want into ratio (which is a number that must go from 0 - 1.

So if the desired mouse range is 20 - 50, you would use something like:

code:

---

xm = _root._xmouse;



// are we in the correct range?

if (xm >= 20 && xm <= 50) {



  // change scale from 20-50 to 0-1

  ratio = (xm - 20) / (50 - 20);



  // optional step - reverse mouse

  ratio = 1-ratio;



  // change scale from 0-1 to 50-500

  endX = (500-50)*ratio + 50;

}

---

The reverse step causes the mouse to have the opposite effect in that range (e.g. mouse on left pushes object to right).

Also notice that equation to get the ratio is closely related to the equation to get the endX (they are both scaling operations, which basically involve multiplication or division by a scaling factor).
