[erlang-questions] How to implement the A Star find path algorithm using NIF?

[skyman]

Hi everybody,


Our game is using A Star algorithm to find path. For performance I want to write it in C language, and Erlang calls it by NIF. I don't know whether the map data is maintained in C or in Erlang. Can anyone tell me?
In addition, is there any better solution than NIF?


Thanks very much!
