Setting this to true redirects writes from Target or from a Source representing the selected value to the currently indexed list entry.
Usage
The component behaves similar to a ValueCopy with the list entry indicated by Index as the value to output. Changes to Index or the list entries will affect Target whenever the drive is evaluated.
In addition, the component implements the IValue interface. This allows the component to be sourced by dragging out the component header with the ProtoFlux tip. This allows one to use the component like an array when sourcing the Index field as well. The source of this component will update instantly, as opposed to the drive being limited to once per frame.
Examples
Array-like access from within ProtoFlux. Note the setting of AllowWriteBack and that you can only access a single value at a time!
