Button Injection
Menu: ALF > Interactivity > Button Injection
Adds a button that learners can press, either on a machine (it moves with the machine) or anywhere in the room. The machine itself isn't changed, except with Clickable part, which makes one of its parts pressable.
Five kinds of button
| Kind | Looks like |
|---|---|
| Flat button | A flat key on a panel. |
| Flat button with a label | The same, with text above it. |
| Push button model | A 3D push button that moves when pressed. |
| Push button model with a label | The same, with text above it. |
| Clickable part | Nothing extra: a part of the machine itself becomes pressable and lights up when pointed at. See Make a part of a machine clickable. |
