Hi. I'm trying to make a gap closer mechanic for my map. I have some-what of an idea; the problem is executing it.

For my gap closer mechanic, I was thinking of placing 4 locations around the unit (left, right, up, and down).
If the unit steps on one of these locations, it moves x units more to the direction it steps on.
If it steps on both, it moves diagonally.

My problem is setting the locations on a unit's left, right, upper, and lower side. ><

You can do this using a mobile grid.

The way starcraft creates units is predictable. Usually like so:


7..6..5
8..1..4
9..2..3

1 being the center of the location.

So knowing this you can create 1 unit and then create the same unit but for another player and then center a location on it and give it to the same player as the first unit you created. In this way you can go around the player creating units and centering locations. Hope you catch my drift.

For a more detailed explanation with images and trigger examples, check the wiki article on mobile grids: http://www.staredit.net/wiki/index.php?title=Grid_Systems#Mobile_Grids

As a bonus, here is a gif I made that shows how to position a location with mobile grids:

Of note here though is that if you constantly (i.e. every trigger cycle) use mobile grids directly on top of a unit, it will slow that unit down, so look out for that.

... which is why you usually follow the unit with the center location and only in the trigger cycle when you actually need the grid create the devourers to space out the remaining 8 locations.
