Q:

How can I create tiles that scale to multiple resolutions?

I am trying to create a multiplayer version of the popular Flash game N in Java. However, I'm not sure how to create a tileset that will scale up. Are the tiles for N pre-drawn or are they defined with mathamatical formulas in code?
I do see how they would scale up in Flash if they were pre-rendered. So if anyone has any ideas how I should go about creating the tileset, or how they are created in the game please let me know.
You can check out the game here.

A:

The creator of N actually put together a few tutorials explaining a little of the technology they used.
Tutorial A is about the collision detection used (separating axis theorem) but may be useful to you.

Tutorial B explains more about the tile shapes used and from the looks of it, they are just a tileset.  Some sample source code can be found at the bottom of the page.
