Switcher

A radio-button list that outputs the index of the selected item — a hand-operated multi-way switch.

Output: number (the selected item's index: 0, 1, 2…)

Inputs

None.

Parameters

Parameter Default Where
items cube, pyramid ⓘ Params tab — edit, add (＋ Add item) or remove entries
selection first item radio buttons on the card

Practical example

Build a two-speed fan switch:

  1. Add a Switcher and rename its items to slow, fast (ⓘ tab).
  2. Add a Select node; wire Switcher → Select's index input.
  3. Add two Number nodes (0.5 and 4) wired into Select's a and b.
  4. Wire Select → a Spin node's speed input, and Spin → an Object Selector targeting your fan object.
  5. Click the radio buttons: the fan flips between slow and fast for everyone.

Tip

The index output pairs naturally with Select (pick between two wired values) and Compare. Legacy note: in older scenes a Switcher with cube/pyramid items wired straight into an Object Selector swaps the target's geometry — kept working for saved graphs.
