If i were to get a series of coords, how would i dispatch an ent to follow the path by the coords? Also, how would I be able to stop and start the *train* when it gets to a certain coord / path checkpoint. Im assuming you could create an info_target with a model, set its velocity, and turn after a certain amount of time? That would be easiest as I can just mess around with the time changes until i get the *train* moving right. Aslo, is it possible to create a bounding box around the *train* model? so when it stops and possibly while moving, playeres will run into it like a wall? I would try this but I have no clue how to use entity_set_*. except setting weapon model, model animation, and view model.
