Channels: proposing GetSlice [Reactive.Channel] #628

Closed antongit closed 1 year ago

antongit commented 1 year ago

Is your feature request related to a problem? Please describe. There is no easy way to convert between human-readable-strings and datatypes when binding. An example is ImGui's Combo (dropdown). UI shows Strings, but the logic is interested in the "values" behind them. (see the screenshot, where the Strings are mapped to Vector2s).

Describe the solution you'd like One can use Merge (Selector), but it's cumbersome. GetSlice [Reactive.Channel] offers an easy mapping of Strings (as an example) to Index, and the Index is then used to choose the "value".

Although GetSlice can be a good old name, it is working with Channels so shouldn't be confused with the old one. Maybe it is still not the best name.

Invented with @gregsn but the node still needs more thoughts about namings.
