Hey everybody,

I need an advice for an algorithm.

 

I'll try to describe what the situation is...

 

I have a structure that looks like this: https://dl.dropboxusercontent.com/u/8655042/struct.bmp

A grid of cells having their coordinates and a value 'X' or 'O'.

 

I'm looking for an algorithm that could build me a path, array of cells that are having value of 'O' and one cell apart from each other (neighbor cells).

buildPath: (x, y) -> array of cells

So if I'll call it like buildPath( 2, 0 ) it will produce output something like so:

[ (2,0); (3,1); (3,2); (3,3); (2,3); (1,3); (0,2); (0,1); (1,1) ]

 

It's not exactly what I'm looking for, but it will help me to start with.

 

Thanks. smile.png

Well what exactly are you looking for?

 

If you want all connected paths from a start point you want the flood fill algorithm http://en.wikipedia.org/wiki/Flood_fill

 

If you want the shortest path between 2 nodes you want A* or Dijkstra's Algorithm http://en.wikipedia.org/wiki/A*_search_algorithm http://en.wikipedia.org/wiki/Dijkstra%27s_algorithm
