The '''ValueMultiplexer''' component allow to curate a list of values and [[Drive|drive]] a target with one of them, much like a multiplexer.

The component behaves similar to a [[Component:ValueCopy|ValueCopy]] with the list entry indicated by <code>Index</code> as the value to output. Changes to <code>Index</code> or the list entries will affect <code>Target</code> whenever the drive is evaluated.
The component behaves similar to a [[Component:ValueCopy|ValueCopy]] with the list entry indicated by <code>Index</code> as the value to output. Changes to <code>Index</code> or the list entries will affect <code>Target</code> whenever the drive is evaluated.
In addition, the component implements the [[Type:IValue|IValue]] type. This allows the component to be [[ProtoFlux:Source|sourced]] by dragging out the component header with the ProtoFlux tip. This enables using the component like an array when sourcing the <code>Index</code> field as well. The source of this component will update instantly, as opposed to the drive being limited to once per frame.

Setting this to true redirects writes from Target or from a Source representing the selected value to the currently indexed list entry.
Usage

Examples
Array-like access from within ProtoFlux. Note the setting of AllowWriteBack and that you can only access a single value at a time!
