Project.

I need to calculate how far out the side of the circle is based on how far up the mouse is. I can't use sin or cosine, because the only information available is the Y coordinate. Please see the project for a demonstration.

Is this even possible? Thanks.

Hmm, judging by the comment you left on one of your scripts, I think I know an alternative to how to solve your problem. I could write it down and you could try to copy what I'm explaining, or I can remix your project and you can just use my script.

I went ahead and just remixed your project. If this isn't what you wanted then let me know.

I appreciate your help, but that isn't quite what I'm looking for. I want to be able to calculate the width of the circle at a certain Y position, without taking the mouse's X into account. In your example, you made it point towards the mouse, taking both X and Y into account.

I changed the animation in my project to demonstrate it better.

Okay, so your question is slightly confusing. I would rewrite it to something like this: “If I draw a horizontal line across a circle at a certain Y value, how could I calculate the distance the circle extends on each side?”

That aside, Does this meet your standards?

define Calculate Distance (size) (y)
set [distance v] to ([2] * ([sqrt v] of ((((size) / [2]) * ((size) / [2])) - ((y) * (y)))))

Here is a small demonstration: https://scratch-mit-edu.ezproxyberklee.flo.org/projects/1136251565/

Well poorly worded question or not, you gave an excellent answer. Thanks!

No problem!
