Hi everybody,

I’m currently working on a small, simple, tile-based game. To hold which tiles go where I am using numbers within 2D arrays to select the type of tile. I was wondering if there was a good way to store the arrays for each map or if I should just write each array out in the Flash program itself. I was also thinking about possibly using .dat files and reading them from there, but I’ve never done anything like that with flash.

I’m using this tutorial, when I need help, and it does not really specify a great way to hold the arrays.

Thanks for the suggestions,
