So after I released Frog Battle multiplayer game for iPad in late 2013, I have been fooling around with Cocos2d and Tiled. Explored some tutorials at Ray Wenderlich's epic site (http://www.raywenderlich.com/39113/cocos2d-x-tile-map-tutorial-part-1). There are two tutorials about creating a tilemap and implementing A* pathfinding algorithm for single-source shortest path problem in a tilemap. I have implemented both in this video.
What you see in this video is a 128x128 tilemap, a miniature tilemap in the upper right corner, and movement of two tanks (T) and a warrior (W) with different movements 3 and 1 respectively. Selecting a unit and dragging it around will display the shortest path to that tile given some obstacles i.e. walls, all adjacent tiles have the same weight/movement cost.
This is a very early video so don't expect that the final product will be anything near this prototype (if it will ever turn into something real at all).
