What is the use of angle in DrawCircle and DrawSolidCircle?

cocos2d-x C++

There is a float angle parameter in
drawSolidCircle (const Vec2 &center, float radius, float angle, unsigned int segments, const Color4F &color)
But changing the value of the parameter seems to have no effect, it draws the full circle regardless of the value of angle.

If you set segments to a low enough number that you make out the lines used to draw the circle, then angle will visible affect its orientation. For example, if you set segments to 5, you get a pentagon. Setting the angle visibly changes its rotation. Perhaps the ability to set the angle is just so people can choose the default way a shape will sit when its rotation is set to 0. Other than that, I can’t think of a use for it.

Thanks Kevin :+1:

I guess I’ll leave it as 0 then.
