# Locations Definition
Where a region's objects stand: their id, their tile, and the shape and rotation they are
placed at.

This is only the placement. What is being placed is a {ref}`TObjectDefinition`.

## LocationsDefinition.Create
```pascal
function TLocationsDefinition.Create(regionX, regionY: Integer; const data: TByteArray): TLocationsDefinition; static;
```
Decodes a region's object placements.

Locations are stored as a run of deltas, so their number is only known once the whole buffer has
been read; the array is grown in doublings while decoding and trimmed to size at the end, rather
than resized once per location.
