It was made very simply.
1)I got a plain.
2)I increased its amount of polygons.
3)I got out a deform tool and manualy deformed the plain to make those hills.
4)You cant see it, but its an island, so I pulled down all the edges with a point and face tool.
5)I added a simple texture by tiling it onto the plain.
6)I got some cubes, textured them with a wall texture, put them together and formed a fort.
7)Exported it as an x format object into the same file as the textures.
8)Added into code.
9)Made a cup of tea.
10)Tested code. Worked.
If you make quite a detailed landscape with the odd tree and bit of grass, then you might not want to use it as collision. Instead, get the original landscape and simplify it, eg. take out grass and take off textures. Add that object to the code in the exact same position as the other one, and turn off the others collision while turning the simplified ones on. Oh, dont forget to hide the somplified one.
Theres also a tool that will let you wrap a matrix around an objects surface, so you can use the matrix for the ground instead. I didnt though.
You can indeed borrow the landscape. Im using it in a project right now though (See WIP, RPG Deja Vu) but I dont really care if you use it. If you still want it, I may need an e-mail address.
