    How to represent a map

    hi,
    I couldn't find anything on web about ways to represent a map. I sometimes improvise, but I thought that maybe there are some "known ways" to represent a map. so?
    (generally speaking of game or simulation program maps that include some info, nothing specific). Also what should I use, a database or a txt file?

    Thank you (:

    Hehe I remember those days. Only I was making the map for Zork instead of Wizardry.

    Why not store it as a graph of nodes and edges (with the edge value being the speed limit)?

    What do you mean?
    Can you demonstrate this way?

    By the way, I'm also talking about represent a map using a file (save the map) not only how to use it in code.

    Does anyone know what kind of data structure is used in a game like Terraria to model the world?

    I'd use a 2D grid of layers. The world doesn't get any wider or taller, so the rows and columns remain fixed. All that changes is what each cell contains, and each one seems to contain a wall and an object (say a dirt wall background, and a dirt square therein). So a simple structure that contains background and foreground should be sufficient.

    No but I do know that you revived a dead thread for no reason. Closed.
