How to make an entity move on X and Z axis?

[The MasterNater]

Thank you Daemian, I'll give it a try and get back to this thread once I have to let you know if it worked or not. Lol, DnAlange, that wasn't quite what I mean (I'm very used to the level editor by now- my fault for not making my question clear), but thank you for trying to help. My issue is trying to script entities to move in-game (much like the cars at the beginning of your Premonition full conversion mod). If you have any advice to add to Daemians, let me know.
