Overview
Control variables let you create toggleable options that operators can adjust in the Control Room during a live broadcast. When you add a Boolean control variable to a FUSE graphic, it creates a show/hide toggle that operators can use in real-time to display or hide graphic elements during matches.
After publishing the graphic, the new control variable appears in the Control Room when the graphic is assigned to an event.
Prerequisites
* Access to the FUSE graphics editor
* An existing graphic project
* Understanding of basic FUSE expressions and element visibility
Adding 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.
6. Set the default value to True so the element shows by default.
Linking the Variable to a Graphic Element
1. Select the element you want to control.
2. Reference the variable in its visibility expression settings.
When the variable is False, the element will be hidden.
Testing and Publishing
1. Toggle the variable on and off in the FUSE preview to confirm the element appears and disappears as expected.
2. Click Publish to publish the graphic.
After publishing, the new control variable will appear in the Control Room when this graphic is assigned to an event.
Tips
* Boolean variables are ideal for show/hide toggles.
* Always set a sensible default value.
* Test all variables before publishing.
* Use descriptive naming conventions like ShowTime, ShowScore, AutoMode.
