问题
I am new to AndEngine and very happy that it's very easy and exciting thing to do. Unfortunately I am unable to draw a curved line in AndEngine.
Actually my scenario is that I have an animated sprite say Object. I want to move this object on a Line with the points given onToucing and dragging it. Now the problem is that I can't find any method to draw a line on points in a way that it does not produce corners. I want a smooth line with no corners.
Suppose I touch the object and drag it on the screen with the points of a square type region. But I don't want the corners in it. I want curves. Previously I am doing this by using quadTo(..) function of android to do this. All I want is a complete alternative to quadto function in AndEngine but with same functionality.

You have to stitch together the curved line from many many small straight lines.
Moving an object along a line is a very different task though. You'd want to have a look at CubicBezierMoveModifier and QuadraticBezierMoveModifier for those.
Maybe you can actually use the code in those modifiers to create your 'smooth' line.
