Hey, I'd just like to ask you a question regarding collision data within Pokémon B/W/B2/W2.
While I am aware there is 2D Collision data (the same type used in D/P/P/HG/SS), I'm also aware there is 3D Collision data as well. Now I'm not sure if you've found anything relating to 3D Collision, but it should be data that uses triangles in which determines the player's north/south/west/east direction.
I haven't found anything relating to that, but I really would like to find it, so I can document about it. It's the collision data that's used in places like Skyarrow Bridge and Castelia City.
There might be some data similar to that in Pokémon Platinum in the Distortion World, when the player switches to walking on the side and all that.
Really interested in finding how its structured and where its located.
