Check the Y value of the oval to see if it is equal to the Y value of the line. Of course, this would make it very difficult, so I would suggest checking if the Y is within a certain distance, say, 5 pixels, of the line.

Sketch this out on paper, and figure out the math from there.

A line has a certain Y value, for the height at which it is drawn.

A circle has a certain Y value, for the position of it's center, at a given frame. The said circle also has a radius.

How would you describe a condition where you are certain that the line is inside the circle?
