Basically the same as Ops.Boolean.IfTrueThen, the only difference is that the output ports are switched.

You can also input non-boolean values, 0, 0.0, '' (empty string) will all evaluate to false. On the contrary 1.234, '5' or 'lalala' will evaluate to true.

You can use it in two ways: If Exe is connected Then / Else will be triggered every time Exe is triggered. If Exe is not connection Then / Else will be triggered every time Boolean changes. This way you can convert a bool to a trigger (function).
