Description
Indicates the position of the component in its owner's Components property array.
Use ComponentIndex when iterating through the Components list of the component's owner to perform some action on owned components. It can be used in conjunction with ComponentCount. ComponentIndex is used internally for iterative assignment procedures.
Note: The first component in the list has a ComponentIndex value of 0, the second has a value of 1, and so on. Therefore, when using ComponentIndex with ComponentCount, note that ComponentCount is always 1 more than the highest Components index.
