Need the math script to determine the X/Y Coordinate from...

[Mikeylkzt]

An ARC.

Hello ALL Math Genious!
I need to get information on how to calculate the X/Y Coordinate of a given PIE Chart.

Let's say I have a circle Divided into 4-5 (not necessarily equal in size) Pie Charts. Now How do I calculate for the X/Y Coordinate of the Center ARC of each pie section?

Did this make sense?

basically it's a circle with a crossSection right in the middle and i want the X/Y coordinate of one of the Sections.


Thanks in Advance

Angelo

P.S. KUDOS to the first one with the solutions.

I'm unclear, can you draw something and post it? i don't really understand. I know someone here (if not me) can figure it out, but I can tell what you want....:) sorry...

Im trying to figure out a formula to figure out the X/Y Coordinate of a given point on a circle.

I can figure out the Area of a circle pretty easy....What I want to do now is try and figure out how to track something on a particular Circular Image.

Almost like a regular clock with the Minutes and the Hours indicator, I want to be able to TRACK ANY POINT of that circle. By using the X/Y coordinate within hte AREA of that circle.

I hope this helps.

Thanks

I don't understand. Maybe someone else will. Sorry. It just doesn't make any sense to me. You are probly explaining it good enough, but I just spend 2 hours trying to fix a flash file for a friend of mine and my brain is fried.

Thanks for trying.. i really appreciate it.

As always, This place is THE BEST place to get info on Flash, If it was not for this board, I would not have been able to keep my current job!


Keep up the good work.

BTW- it's been about 2-4 months since my last posts.

i'm not sure just what you mean either, but this might get you started ...

remember trig?

make a movie of a largish, unfilled circle with it's registration point at its center.

within that movie, make a movie of a small filled circle, also with it's registration point at its center.

select the small circle movie and put this code on it:


onClipEvent(mouseUp){

var x = _parent._xmouse;

var y = _parent._ymouse;

var r = _parent._width/ ((x<0) ? -2 : 2);

var ang = Math.atan(y/x);

_x = Math.cos(ang)*r;

_y = Math.sin(ang)*r;

}

click away.
