Can I make my own landscape and also have it to where the get ground height works on that object?

How would I go about doing this if I wanted to?

Lol, I wasn't askign how to make one. I have it already made.

How do I make it act as a matrix to where I say Get Ground Height, or does it do that automatically?

He wants to use it as a heightmap, not just position it.

You can use models like a mesh, but I haven't looked at how it is done yet.

Sparky's collision DLL (search in the DLL Talk forum for 'sparky collision') has a DBC version. It's essentially a really fast intersectObjectDBC() function, that allows you to shoot a 'ray'. It'll then return what objects the ray passes through.

The examples included in the archive are more than enough to get you started; they'll serve as a nice introduction at least. The idea is you fake your own get ground height() function by shooting a ray from the player's feet downwards a little bit. If there's nothing there, move the player object down (i.e. gravity). If there is, cement the player's feet to the object.

Not easy, but models/objects can be used to make faster-rendering landscapes than matrices. intersectObjectDBC() is extremely versatile, once you get a feel for it...
