Well this modding question has been asked about a hundred times, 101 won't hurt

Not at this time.

You can make a new unit class that is functionally identical to ships, but without the ability to warp, though. Not quite the same, but its something.

Fyron's right, the ability (something_need_component/ability to transit warp point) is not functional at this point. It has a place holder in the coding but its not turned on yet.

I've tried this as well: auto close warp point after transit - not functioning either.

problem with units, I'm pretty sure that they are built without a spaceyard. Aaron needs to make it so we can have a file like "Vehicles_Ship_Types.txt" for the space yard.

I'm not sure if it would work but...

Seeing as how warp points can have size restrictions (e.g. anything bigger than "x" will not be able to use the said warp point) one could easily change the Ship Types (or hull sizes I can't remember) so that they are far bigger than the warp points and by using a special component reduce the size of the hull so that they can get "through" the warp point.

Would that work?

No, the warp point size feature is unimplemented.

I think someone else suggested an ECM value for the warp point...
Need scanners above a certain level to see and use the warp points...
This could allow for the "discovery" of new warp points...
I could also limit warp point usage...
