Overview
Boolean control variables create on/off toggles that operators can adjust in the Control Room during live broadcasts. Use them to show or hide graphic elements in real-time, such as match clocks, sponsor logos, or player statistics.
You add Boolean variables in the FUSE editor's Control Variables panel, set a default value, then link them to graphic elements through visibility expression settings.
How to Add a Boolean Control Variable
1. Open your graphic in the FUSE editor.
2. Navigate to the Control Variables panel in the right-hand panel of the FUSE editor.
3. Click Add Variable.
4. Select Boolean as the type.
5. Name it something descriptive like ShowTime, ShowScore, or AutoMode.
6. Set the default value to True or False. Setting it to True means the element shows by default.
7. Click to confirm and add the variable.
How to Link the Variable to a Graphic Element
1. Select the element you want to control in your FUSE graphic.
2. Reference the variable in the element's visibility expression settings.
3. When the variable is False, the element will be hidden. When True, the element will be visible.
How to Test and Publish
1. Toggle the variable on and off in the FUSE preview to confirm the element appears and disappears as expected.
2. Once verified, publish the graphic.
3. After publishing, the new control variable will appear in the Control Room when this graphic is assigned to an event.
