Coordinate systems? #8

Closed kazimuth closed 9 years ago

kazimuth commented 9 years ago

I'm trying to implement block selection in Unity and I'm running into some issues figuring out how to translate between Unity coordinates and Dwarf Fortress coordinates. I was wondering if we could document some things in GameMap. Specific questions:

The DFtoUnityCoordinate function returns a point at the bottom center of the block.

Both Unity and DF share the origin at 0,0,0

Unity uses y is up, and z is north. Unity uses Z is up, and y is South.

  • What would a function mapping from a location in Unity-space to a map tile/block GameMap index look like? (specifically, to the coordinates of the 8 corners of the block?)
  • What coordinate does DFtoUnityCoordinate return, relative to the cube that is a block (in the center of the top, I think?)
  • How do the Unity origin and the Dwarf Fortress origin relate to each other?

And is (0,0,0) the corner of a map block?

It's the bottom North West corner of the entire map.

Hopefully more documented now.
