Why the need to reverse the map?

I see. Thanks. OK I'll make a point of referencing your gihub page when I make my game public. :)

I wrote the code a very long time ago, can you point out exactly where this is?

Yeah it's the Level.generateMap method you added the comment // Reverse the list so the row index will grow as the z index

I'm not sure what that means. Is it because this is the way JavaFX expects the objects to be added? I tried reversing the for loops and I didn't see any difference. Or could it be because of the Perspective Camera orientation?

Thanks for replying BTW. This this is very nice sample on how to make a 3D maze. In my case, I don't only use Blocks. I also use other object types which need the correct orientation.

I think the answer simply is because the map is saved as a 2D matrix in the map data files, and naturally the row index starts at 0, at the top left corner, and increases downward (like pixel coordinates on the screen). But if we reverse the lines and face "upward" on the plane of the map, then increasing row index will correspond to increasing z coordinate.

I don't think this has much significance, this might have just been more natural to me, and might result in somewhat easier calculations. Does not have a big impact.
