Math - how to find oval radius at a certain angle?

Hello.

I have trouble to find an equation that can calculate an oval radius c lenght, while having the leading radius a, radius b and angle alpha.

If anyone could help, I would appreciate a lot!

(sorry for my english I hope I am clear).

Thank you in advance.

So basically:

distance(centerX,centerY,centerX+cos(angle)*a,centerY+sin(angle)*b)

Actually no - I did try that at first, but that only works for a circle, not an ellipse. You can try it - it gives a point on the ellipse, but it does not match the angle.

Check the distance between the sprite you created, and the center.

Your formula is different than the one you used to make the loop.

I mean there is no set definition of "oval", so it doesn't matter how you set it up, so long as you always use the same rules.
