How do I stop every SINGLE unit at a specific location?
I mean, STOP, at all, not being able to move, and no, not moving the unit on its own location, something un-specific.
Example:
As in Crazy Missile (Fleet Beacon) at Missile Warfare T1.1, something similar to that...
Help would be highly appreciated.

Move to a location they can't go to. Like water.

I shouldve mentioned, AIR units.

I would recommend constantly moving them(with hypers) to a location OUTSIDE the map, this can be done by modifying the coordinates of a location so it is outside the map, this creates less lag than moving it to an implaceable area inside the map, and it works on both air and ground units.

Note, however, that these units will basically dodge any attacks done to them, because they are constantly moving, almost anything you try to hit them with will miss.

Move to a location outside the map. I'm sure there is a wiki article on this.

Outside the map, as in, expanding it with dimensions to like, 257x257, then resizing it to 256x256?
If that works, thank you alot.

It's easier if you just change the coordinates of the location so it's outside the map, place it right next to the edge then just add a bit to it's current coordinates.
