| - | When the event range is triggered it checks the value of the event call against the range and triggers either the list of events when inside or outside of the range. E.g. a button could generate a message with value 1.0 which is received by an input_event and then the input_event triggers this event_range. Depending on what the button value was the event_range does one thing within a set range but does something different when the value is outside that range. | + | When the event_range |
