Bool

A Bool is a checkbox: on or off. Operators use it for things that are either done or not, such as whether outputs that are not active are emptied. Click the box to switch it.

Any parameter can drive a Bool. A number that is not 0 switches it on, and 0 switches it off. Text is read as a number first, so the word true does not switch it on. As a source, a Bool sends 1 for on and 0 for off, which makes it useful for switching a signal on and off through a Math operator.
