Penumbra Worm...

[Neelke]

Well, I've figured out one way of getting it's animations to work. There's an example in The Fugitive 3.

Basically what I did there was converting the actual animation, making it into a static object with the mass 5. Then I converted a block box to a move object which now works as an invisible move box that can be moved the direction you wish (and pushing the worm forward). This is more complex than the other one and it still needs to be linear, but it works.

It's slightly harder script here, but I'm assuming you want animations really bad.
