Simple but frustrating problem, please help

that's not going to work. assign centerX and centerY to be 0 and 0 and you'll see what you're really doing.

with centerX and centerY greater than r, you're not doing anthing by using Math.abs().

i'd use a variable to indicate if sharps or flats are to be displayed. then use an if-statement to assign text to the notes.

Hey, not sure if you're still checking this (since I marked it answered), but here goes...

I wanted to modify it so the points start at the top of the circle and go clockwise right. After working through your code and re-acquainting myself with some of this trig stuff, I came up with this:

pt.x = Math.abs(r*Math.sin(i*Math.PI/180)+centerX);
pt.y = Math.abs(r*Math.cos(i*Math.PI/180)-centerY);

Do you see any problems doing it that way? It worked on the preview, I just have to modify the text label positioning.

Also, since this is for musical notes (i.e. C, C#, D, E#) I wanted to put a button on the stage that lets the user choose whether they see sharps or flats on the labeling -- so C, C# vs. C, Db.

Would it be best to take the textual label part of the code and put it into it's own function that handles the event of whether the "Sharps/Flats" button is pushed?

Could I just make an array with the note names...one for sharps and one for flats, and then apply one or the other depending on the stage button?

Hey, thank you so much for all the help.

One last thing...when adding the labels, how do I attach them to the points? I was looking for a function of "pt" like ".addLabel" but didn't see anything.

I'm guessing I have to use another type of object for it but I'm a little confused.

Thanks again, I'll be marking your previous post as the answer later today.

and you can make that for-loop a little more efficient by using:

for (var i:int=0; i<360; i+=30) {
// comment out the if(i%30)
// and there's no need to define ivar. just use i instead of ivar.

Hey that code you sent looks pretty cool. It's not exactly what I need but it's a huge help as far as understanding it goes. I'm gonna pore over it for a little bit.

The one thing I need to change-- clearing the former triangles when a new point is clicked (should just be a call to "clear" I'm thinking). The program is actually for explaining a certain piece of music theory if you're interested.

It's an animated version of this:

I guess I don't really need the outside circle. What would be the best way to "attach" the note names to the created points?

Thanks again, you saved me a lot more frustration.

here's one way to do it if you want to pick random (except for the clicked point) pts to form the triangle:

how do you determine the two other points to use in forming your inscribed triangle?
