Struct MapObjectsAtCastEnumerator<T>
A custom enumerator used to iterate over all objects on a Map which are at a given location on given layers and are of a given type efficiently. Items are returned in order from highest layer to lowest, as applicable. Any items not of the given type are ignored.
Generally, you should use GetObjectsAt<TObject>(Point, uint) or one of that function's overloads to get an instance of this enumerator, rather than creating one yourself.

Syntax
public struct MapObjectsAtCastEnumerator<T> : IEnumerable<T>, IEnumerable, IEnumerator<T>, IEnumerator, IDisposable where T : IGameObjectType Parameters
| Name | Description |
|---|---|
| T | The type of items to look for. |
Remarks
This type is a struct, and as such is much more efficient when used in a foreach loop than a function returning IEnumerable<T> by using "yield return". This type does implement IEnumerable<T>, so you can pass it to functions which require one (for example, System.LINQ). However, this will have reduced performance due to boxing of the iterator.
