ValueMultiplexers allow to curate a list of values and [[Drive|drive]] a target with one of them.
They implement [[Type:IValue`1|IValue]] which means that a reference to them can be used to create a [[ProtoFlux:Source|Source]] node representing the currently indexed value. This enables using them like arrays when combined with a <code>Source</code> of the <code>Index</code> field.
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.
Changes to <code>Index</code> or the list entries will affect <code>Target</code> whenever the drive is evaluated.
On the other hand the <code>Source</code> of this component updates instantly.
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.
