No, C is the unknown and it can be anywhere. Its directly dependent on A and B. I know point A, point B and the angle of the arc that needs to be drawn between them. I assumed I'd need to provide a starting angle for the arc but now I don't think that's necessary.
In the drawing, C is the...
In thi case the positive x-axis (angle 0) (originating from the center) and the radius from C to A form the starting angle. Now that I think about it, the starting angle doesn't need to be given, it can be derived by which point A or B forms the lesser starting angle.
by starting angle I'm referring to the the angle the starting point makes relative to the center. That is where the arc angle starts (its just simply the angle the starting point makes)
I'm trying to find the equation for a circle given two points in x, y and the starting angle, arc length, and two points along the circle. I need to find the equation because I need to translate a sprite along the curved path from one point to another.
The situation ends up looking like this:A...
