XNA Physics & Terrain

[Crisisonfire]

To a degree yes, each cube is an instance of the cube physics object.

In terms of doing this in GameMaker i have no idea how you would do it as i've only done basic 2d games.

XNA is worth the effort to learn and use =]

Not really, simply create a shader and define an instance of it which i can toggle to being visible or not

was the blur hard to do?

Should be a simple shader.
