# Area Definition
Map areas: the named places the world map labels and the icons the minimap draws for them.

## AreaDefinition.Create
```pascal
function TAreaDefinition.Create(id: Integer; const data: TByteArray): TAreaDefinition; static;
```
Decodes a map area - the named places the world map labels, and the icons the minimap draws for
them.

`SpriteId` is what {ref}`TMapDataLoader.LoadAreaIcons` turns into the icon itself. The opcodes
this does not keep are still read past, because the stream has to stay aligned for the ones
that follow.

## TAreaDefinitionArray.IndexOf
```pascal
function TAreaDefinitionArray.IndexOf(id: Integer): Integer;
```
The position of `id` in the array, or `-1` if there is no such area.

Area definitions are stored one per id with no gaps, so an id is its own index; this exists to
keep that assumption in one place.
