Cool usage of the "Not" operator

[trevorg]

I just learned something and thought I'd share.

In the past whenever I wanted to use a field as a toggle (on, off) I would write a script that would check if on/true/1 then set it set it to off/false/0 , else set it to the other on/true/1.

This can all be replaced with just ONE set field and no [if's] inside.

Lets say we had the field called "Toggle" and it's a number field. Since this technique only uses the 0, and 1 (0=off, 1=on), then a number field makes sense to me.

If we simply make a set field command like this:

Set Field ["Toggle", "Not Toggle"]

This automatically flips the 0 to a 1, or a 1 to a 0.

The only problem is if the field is empty to start, then it doesn't enter anything.

I thought it could be useful and wanted to share.

To deal with the null field issue, you can use the slightly less "streamlined" version:

Set Field ["toggle", "Case(toggle, not toggle, 1)"]
