Properties

Public property AsArray [const Index: TIndex]: Byte read GetItems;

Get vector components by index. This is a default property, so you can write MyVector[0] instead of MyVector.Data[0] or MyVector.AsArray[0].

But note that this is not writeable (because exposing writeable properties on vectors would cause some subtle traps, see https://castle-engine.io/coding_traps ). Use MyVector.Data[0] := 123 if you want to set by index, or MyVector.X := 123.
