It would be much easier to write a script that converts illa mapdata to minecraft data.
Illa map data has tiles data, and item data. Let's call the floor number n, for which the ground (the overworld/oberwelt) floor has n==0.
First you'd make a Minecraft map file which would be pure ground from the 0th floor down, empty up from there.
You'd dlmread (or stream in .NET or whatever you use) in the tiles.txt for the nth floor. With this you'd set the (x,y,3n)th elevation coordinate minecraft blocks to whatever tile that is. So a grass tile would equate to a grass minecraft tile etc.
For water it'd be more difficult to distinguish between a river and the ocean. You could do that by examining nearby tiles but you'd likely make lakes into bottomless water pits. However, for the most part I think it'd be easier just to make it so if it reads water, it'd set water all the way down to the bedrock.
Then you'd read in the items.txt from the nth floor files, and depending on the item it read in it would yield different results. For instance, say you're reading any object 30, 31, 32 or 33, you'd want this to create a standard brick wall. Therefore for these object ids, you'd set it to write the (x,y,3n+1)st and (x,y,3n+2)nd coordinate floors to walls. Say it was object 321, you'd spawn a chest at (x,y,3n+1). say it was 724/725, you'd set (x,y,3n+1) to a crafting table.
Then you'd iterate through, repeating for e.g. the (n+1st) floor.
So, for example, if you started at n=0, you'd be settings the tiles (x,y,0) to the floor, then (x,y,1) for small objects and (x,y,1)&(x,y,2) for large objects, then the first floor the tiles would be (x,y,3) and its objects would be (x,y,4) and (x,y,5).
You'd also have to write something such that if two items occupy the same space it would stick the second one on top of the first one, rather than overwriting it.
I'm not familiar with how minecraft processes map data, but I believe it's raw editable in the same way that illa's map data is from text files, so it would probably be about 4/5 hours' work tops to write a script to fully convert illa map data to minecraft data.
I'm busy making my android game right now (
Press release), but if I'm bored and find some spare time in the coming week I'd be happy to write a script for it. Sounds fun. The only issue is whether that's a problem with the illa team, because obviously.. it is their map data. It's not in my place to go converting it to Minecraft data if they don't want that. But if they're cool with it I'm happy to do it.
