Moving grid?
Hi there, I'm new to portal mapping, and have started making a map. For one part though, I need a moving emancipation grid (Specifically, It has to follow a path) I was just wondering if this is possible. Any help would be much appreciated

It depends if it's going straight or using a complex path(IE; Straight, left, etc) If it's straight you could parent it to an invisble door, if it's more complex, you'd have to use path_tracks and func_tracktrains.
I've made a moving (forward to backward in the x/y plane) fizzler, and one moving vertically upwards and downwards. If you want ideas, the first one is in the third chamber of The Electric Castle, and the second was part of a puzzle that got axed. As said, if you're following a more complex path then a func_tracktrain is the way to go, but if you're moving along a simple path (front to back, vertically) then you can easily do the same thing with a func_door. This: http://i30.tinypic.com/2zrf3ox.jpg is the only picture of it I can find, I can give you some better ones when I get back =)
Edit: in the pit, there's some piston-like brushes that explain the movement of the fizzler, one of these has a nodraw func_door in it, and everything is parented to this.
You may run into problems if you try and move it too fast; the particle effect starts to lag behind the models after a particular speed.
How it works, is a semi-complex (Forward, down, backwards, up, repeat) pattern. I was more wondering if it COULD be done, before I start playing with the pathtracks. I'll look at a moving platform or elevator for how those work. Thanks guys!
EDIT: Actually, there might be an easier way to do what I'm trying to do, I need A grid to move from one end of a hall, t o the other, then start at the first end again. I know I could get it to slide down the hall, then go through the floor, move back to starting position, and raise back up. Is there anything hammer can do to teleport a emancipation grid?

I'm not sure about actualy teleporting it, but if you wanted you could probably kill it at the end, then spawn another one at the start.
It's probably easier to do your first suggestion with a tracktrain - that'll be pretty easy.
