is their any way by which i can create no of dots to cover width and height of Sprite.
there are a couple of ways on doing that, either making a bunch of image points on the edges of your sprite and then create dots from point 1 to point 2 and so on, or use canvas plugin to detect the color and pixel position but that would be to complicated and for mobile would eat a lot of performance, or use the bbox left right top etc.
but since is a circle, and if it spins is still a circle, the dots won't make any animation no matter what cause there is no change in the shape is always going to look the same. the led system is meant for odd shapes like rectangles, triangles etc, circles aren't one of those, cause no matter the angle you put the circle at or position it will still look like a circle.
id just make a sprite with dots on it and put a webgl color effect to change colors based on movement progression or some random factor.
