Default value
list(src.loc)
This read-only var tells which turfs are being physically covered by the atom’s bounding box. The purpose of this is for cases where you set the atom’s bounds to change its physical size so that it ends up covering more than one turf.
This is different from the loc var in that every atom still has only one “true” location. A movable atom may cover multiple turfs, but only one turf is its loc. The loc var can be thought of as an anchor point, while the actual physical footprint is in locs.
For every turf in locs, this atom will also be in that turf’s contents list.
If loc is not a turf, it will be the only item in the locs list. If loc is null, locs will be empty.
