Path finding algorithm for 2d game

I want A* path finding algorithm for my 2d game. I have read about NevMesh but it doesn’t work for 2d game. If you guys have implementation of A* algorithm for 2d game then please share it.

I have to write algorithm from my self. I can’t able to find 2d implementation of A* path finding algorithm.

To write algorithm, I found basic explanation from following site :
Introduction to A* Pathfinding

I really appreciate their work. I have written code from their explanation as per my requirement if anybody want this implementation then message me any time.
