Branching condition events.

This might seem very trivial but how do I do a branching condition check?

I've tried doing it this way but it doesn't seem to work at all.

Make the System Rotation a OR Block, that way it only execute 1 action.

Vitae : the OR condition is the right one.

In fact, in your example, I'm pretty sure that, if the "Rotation = 0" is true, then the Rotation is set to 1, and on the following one, "Rotation = 1" is true. A classical example where you need to debounce your event.
