A* Pathing implementation for NodeJS in Coffeescript
(Forked from bgrins' awesome Javascript implementation via MIT License)
Uses a Binary Heap for speeeeeed!
Note: This is just the server-side code to get a* pathing working in NodeJS. If you want the client-side code, check out bgrins' library here: https://github.com/bgrins/javascript-astar
npm install astar
Create the Graph:
Graph = (require 'astar').Graph # This a* implementation uses a graph
graph = new Graph 10
Search the Graph: # Starting point x = 0 y = 1
# Ending point
end_x = 8
end_y = 9
graph.path x, y, end_x, end_y, (path) ->
# Do stuff with the path here or do a callback path to use it elsewhere
Add some walls: # We want a wall at 5, 6 x = 5 y = 6
graph.set 5, 6 ->
To run the tests npm install
